Chapter 12: Intravenous Therapy and Blood Administration

Welcome to Last Minute Lecture.

This free chapter overview is designed to help students review and understand key concepts.

Welcome to the Deep Dive.

Today we're tackling a really fundamental area of healthcare, intravenous therapy and blood administration.

Yeah, absolutely essential stuff.

Think about those moments when getting essential fluids, medications or even life -saving blood into the body quickly, efficiently,

it's critical.

That's really the power of IV therapy.

Exactly, and we've got a pretty substantial resource here, a chapter that really unpacks the core principles from the Saunders Comprehensive Review.

So our goal today is to explore these concepts, really dig in, so you walk away with a solid understanding of how and why these procedures are just so vital.

And why should this grab your attention?

Well, whether you're directly involved in healthcare, maybe studying to be, or honestly, just curious about how the body's supported during illness,

this is foundational knowledge.

By the end of this deep dive, you'll see the intricate details, the critical thinking that goes into something that might seem, well, routine sometimes.

And it often does seem routine, but there's a lot to it.

Let's start right at the beginning then.

Intravenous therapy, what are the main reasons we actually use it?

Well, the chapter lays out several key scenarios.

First and foremost, it's a lifeline for individuals who just cannot take in fluids, electrolytes, or nutrients orally.

So if they can't eat or drink normally?

Precisely.

It ensures they still get what their body needs to function.

Secondly, and this is important, compared to taking something by mouth, IV therapy allows for a much faster correction of imbalances.

Faster is key sometimes.

Think of it as a direct route, you know?

Straight to where it's needed most, bypassing that whole slower process of digestion and absorption.

So in situations like,

say, severe dehydration or maybe malnutrition, that speed is really of the essence.

Absolutely.

And thirdly, IV therapy gives you immediate access to the vascular system.

Right into the veins.

Which allows for swift delivery of solutions.

That's a huge advantage when time is critical.

And finally, it's the standard, the established method for administering a whole range of medications and, of course, blood components directly into the bloodstream.

It really is quite the toolkit then.

Now when we talk about how these fluids get in, the chapter details various 5E devices.

Let's kick things off with butterfly sets.

What are their key features?

Okay, butterfly sets.

Sometimes called winged infusion sets.

They have a needle with these little plastic wings on the side.

Ah, the ones you pinch.

Exactly, you pinch them for easier insertion.

The needles themselves are typically pretty short.

Maybe half an inch to one and a half inches long.

And the gauge.

Gauge, okay, that's a term we hear a lot with needles.

Remind us what that signifies.

Right, think of the gauge number as, well, inversely related to the width of the needle's opening.

The lumen.

It's a smaller number, bigger hole.

Exactly.

A smaller gauge number actually means a wider lumen.

A wider inner channel.

It allows for greater flow.

Now, for butterfly sets, the gauges usually range from 16 to 26.

Okay.

And the chapter points out that infiltration.

That's the leaking into the tissue.

Yeah, where the fluid leaks out of the vein into the surrounding tissue.

It can be a bit more common with butterfly sets.

They're just, well, relatively stiff compared to other types.

So given that potential drawback, that stiffness, when are butterfly sets the go -to choice?

Well, they're often preferred for children

and older adults, people who tend to have smaller, more fragile veins.

Makes sense.

You might also see them used in outpatient settings for short -term infusions, you know, where you don't need that more secure, longer -term access.

Okay, so delicate access, short -term.

What about plastic cannulas?

How are they different?

Plastic cannulas.

They're primarily designed for short -term therapy too, but especially when a rapid infusion is needed.

More comfortable, I imagine.

Generally, yes.

They offer more comfort for the client compared to that metal needle of a butterfly set, at least once the plastic cannula itself is inside the vein.

Comfort's definitely a factor patients appreciate.

Is there anything to be particularly mindful of with plastic cannulas?

Yes, there's a potential risk, though rare, of catheter embolism.

Embolism, meaning?

It's a rare but serious complication where the tip of the plastic cannula could actually break off during insertion or maybe removal and then travel through the bloodstream.

Wow, okay.

That certainly underscores the need for, well, careful technique.

Absolutely.

Now, we've mentioned gauge a couple of times.

Let's really solidify our understanding of IV gauges and how they influence the choices we make.

Okay, so, as we said, gauge is the diameter of the lumen, and remember that inverse relationship,

smaller gauge number equals larger outside diameter of the needle.

Got it.

Smaller number, bigger needle.

That's the crucial point.

Now, selecting the right gauge depends on a couple of things.

The type of solution you're infusing thicker solutions need a wider lumen and, of course, the diameter of the client's vein.

Stands to reason.

And a larger lumen, meaning that smaller gauge number, allows for higher fluid rates.

You can also give more concentrated solutions without excessive pressure.

Can you give us some specific examples?

When would you use different sizes?

Sure, absolutely.

In situations requiring rapid emergency fluid resuscitation, maybe blood transfusions or administering anesthetics, you'd typically reach for a larger gauge.

Think 14, 16, 18, or even 19.

Big ones.

For high volume, high speed.

Exactly.

For more standard, routine IV fluid infusions, a 20 or 22 gauge is generally sufficient.

The workhorses.

Pretty much.

And then, when you're dealing with very smaller, fragile veins, like in some elderly clients or infants, you might need to use a smaller 24, 25 gauge needle to minimize trauma.

Okay, that provides a much clearer picture of gauge selection.

Let's move on to what actually holds these fluids.

The IV containers.

What are the key things to look out for?

Right, IV fluids typically come in either glass bottles or plastic bags.

With the plastic bags, it's really vital to give them a good squeeze.

Check for any leaks or tears that could compromise sterility.

Makes sense.

And glass.

With glass bottles, you need a careful visual inspection for any cracks.

And regardless of the container type, always hold the solution up to the light.

Examine it for any cloudiness, little bits floating around or discoloration.

That could mean contamination.

So visual checks for integrity and sterility.

What about expiration dates?

Seems basic, but critical.

Oh, absolutely fundamental.

Always, always verify the expiration date on the IV fluid bag or bottle and on all the other supplies you'll be using, like the tubing.

Don't want expired fluids.

Definitely not.

And if you're preparing medications that need to be reconstituted.

Mixing powder and liquid.

Right.

You have to strictly follow the reconstitution instructions from the pharmacy and your facility's protocols.

And I remember reading something about not writing directly on the plastic bags.

Why is that?

That's correct.

You want to avoid using standard marking pens, like Sharpies, directly on plastic IV bags.

The ink can actually leach through the plastic.

Seriously.

Into the solution.

It can, potentially contaminating the solution inside.

So instead, always use a proper label and a ballpoint pen to clearly mark the bag with all the necessary info, making sure that label is stuck on securely.

Smart safety tip.

Okay, now let's talk about the delivery system itself.

The IV tubing.

Looks fairly standard, but I gather there are nuances.

Definitely.

Standard IV tubing, you know, typically has a few key parts.

There's a spike that pierces the IV container.

Got it.

Then a drip chamber, where you can actually see the fluid dripping and count the rate if needed.

A roller clamp to manually adjust the flow rate.

The little wheel thing.

That's the one.

Often there's a Y -site, which is an injection port for giving meds or connecting secondary infusions.

And finally, an adapter that connects to the IV catheter in the client's vein.

Some newer sets might also have special segments for electronic infusion pumps.

The chapter mentions secondary tubing.

What's its purpose?

Secondary tubing is usually shorter.

It's specifically for administering piggyback medications or smaller volumes of fluid that you give, in addition to the main continuous infusion.

Like adding something extra.

Exactly.

This secondary tubing connects to a designated injection port off in that Y -site on the primary 5E line.

Usually you connect it to the port closest to the drip chamber.

That helps make sure the piggybacked medication gets fully infused.

Are there any specialized types of IV tubing we should know about?

Yes, actually.

Certain medications have a tendency to be absorbed by the plastic in standard IV tubing.

So the patient wouldn't get the full dose?

Potentially, yes.

In those cases, you need specialized tubing made of different materials to ensure the client receives the intended dose.

You always have to consult the medication administration guidelines to see if specific tubing is required.

Good to know.

Vented versus non -vented tubing.

This sounds like it relates to how the fluid flows out of the container.

Precisely.

It's all about how air enters the IV container as the fluid leaves.

Vented tubing has a built -in air vent.

Okay.

This type is essential when you're using rigid containers like glass bottles or some hard plastic ones.

Without a vent, a vacuum would form as the fluid drains and the infusion would just stop.

Ah, okay.

So non -vented is four.

Non -vented tubing is used with flexible containers like the common plastic bags.

They just collapse as the fluid infuses so you don't need that air vent.

Makes sense.

Interestingly, if you only have non -vented tubing but you need a vented system, say for a glass bottle, you can often use a special vented adapter to convert it.

That's a handy workaround.

The chapter also talks about extension tubing.

When would you add that to the setup?

Extension tubing is basically just what it sounds like.

Additional lengths of IV tubing connected to the primary set.

To make it longer?

Yeah.

It can be really helpful for increasing the client's mobility.

For instance, allowing a child to move around a bit more freely or giving more slack for restless patients so they don't pull on the IV site.

Okay.

Moving down the line to drip chambers, we've got macro drip and micro drip.

What's the fundamental difference there?

The main difference is the size of the fluid drops they produce.

And that determines the drop factor, which is the number of drops it takes to equal one milliliter written as GTTML.

Got it.

Drops per milliliter.

Right.

Macro drip chambers deliver larger drops.

They're typically used when you need to infuse a larger volume of fluid or if the solution is thick or maybe needs to be given relatively quickly.

So bigger jobs.

Kind of.

Their brink factors generally range from 10 to 20 GTTML, but, and this is important, always check the specific tubing packaging.

It can vary by manufacturer.

Always check the box.

And micro drip.

The name suggests smaller amount.

Exactly.

A micro drip chamber has this short vertical metal piece inside where the drops form.

It delivers a much smaller, finer drip.

And the drop factor.

The standard drop factor is usually around 60 GTTML, but again, always verify on the packaging.

So when would you use micro drip?

It's ideal for situations needing slow, precise infusion rates, typically less than 50 millimiles per hour.

Or when you're giving potent medications that need to be carefully titrated, like you see in critical care or pediatrics.

Okay, so macro drip for volume and speed,

micro drip for accuracy, and slower rates.

That's clear.

What about filters?

What role do they play?

Filters are designed to trap any tiny particles that might be in the IV solution.

Like little bits of stuff.

Yeah.

Could be tiny bits of rubber from a vial stopper or other microscopic contaminants.

The filter prevents them from entering the client's bloodstream, which could cause complications like phlebitis or even an embolism.

When are they typically used?

Filters are considered standard practice when you're administering blood and blood products.

They're also often used for clients who are neutropenic.

Low white blood cell count.

Right, meaning they have a very low white blood cell count and are at a higher risk of infection.

The filter adds an extra layer of protection.

Needless infusion devices, this seems like a really crucial innovation for healthcare worker safety.

Oh, absolutely.

Needless systems are specifically designed to minimize the risk of accidental needle stick injuries.

How do they work?

They use features like recess needles that never get exposed or blunt plastic cannulas and special one -way valves.

These allow you to connect syringes or tubing to the IB system without using a sharp exposed needle.

A huge step forward in safety.

The chapter also mentions intermittent infusion sets.

What are their main uses?

Intermittent infusion sets.

You might hear them called saline locks or sometimes heparin locks depending on what's used to flush them.

They're used when a client needs IV medications or solutions given intermittently periodically but doesn't need a continuous IV infusion running all the time.

So it gives you access when needed but the line isn't constantly flowing.

Exactly.

It provides venous access without the constant fluid flow.

How do you keep those lines from clotting off between uses then?

That's where flushing comes in.

To maintain patency, which just means keeping the line open and clear of clots, these sets need to be flushed periodically.

With what?

Usually with normal saline solution.

It's also standard practice to flush the line immediately before and right after you give any medication through it.

Makes sense.

And the specific volume of saline to use and how often to flush.

That should always follow your hospitals or facilities established policies.

Right, check the policy.

Finally, in terms of equipment, we have electronic infusion devices, IV pumps.

What's their primary advantage?

Electronic infusion devices, pumps, controllers, syringe pumps, PCA devices for patient controlled pain relief.

They offer much more precise and consistent delivery of IV fluids and meds compared to just relying on gravity and that roller clamp.

So you can set the rate exactly.

Yes, you program a specific infusion rate, say milliliters per hour, and the device actively works to maintain that rate.

So it takes a lot of the guesswork out of flow control.

It certainly provides a greater level of control and accuracy.

However, and this is a really critical point, the chapter emphasizes these devices are not foolproof.

You still absolutely need to diligently monitor the infusion rate, check the device's settings regularly, make sure it's actually functioning correctly and delivering the prescribed amount.

Electronic devices enhance safety, yes, but they don't replace vigilant nursing assessment.

That's a great reminder.

Technology is an aid, not a substitute for careful observation.

Let's shift focus now to a really critical consideration in any IV therapy, latex allergy.

Sounds like a key part of that initial assessment.

Absolutely paramount.

You must always specifically ask the client about any known allergies to latex before starting any IV therapy.

Why is it so critical with IVs?

Because many components used in the procedure can potentially contain latex.

The IV catheters themselves, parts of the tubing, injection ports, especially those with rubbery stoppers, the stoppers on medication vials, even some types of adhesive tapes used for the dressing.

It's potentially in a lot of places.

So how do healthcare providers identify latex -free products?

Fortunately, manufacturers are generally very good about clearly labeling products made without latex.

So look for the label.

If you have a client with a documented latex allergy, it's essential to carefully check the packaging of all your IV supplies to ensure they are explicitly marked as latex -free.

The chapter also notes that there's a more detailed discussion of latex allergy elsewhere in the book, highlighting its broader significance.

Okay, good to know.

Moving on to the practical side of inserting a peripheral IV, what are the preferred spots on the body?

In adults, the veins in the forearm are usually the most frequently chosen sites for peripheral IVs.

Why the forearm specifically?

Primarily because the bones of the forearm provide a kind of natural support structure.

It helps stabilize the IV catheter and reduces the risk of it moving around or getting dislodged.

Makes sense, like a built -in splint.

Are there any areas that are generally avoided for peripheral IVs in adults?

Yes, definitely.

Veins in the lower extremities, legs, feet, are generally not recommended for routine peripheral IVs in adults.

There's a significantly higher risk of developing a thrombus, a blood clot,

and also fluid tends to pool more easily in the lower extremities because of, well, decreased venous return that can lead to complications.

The chapter actually includes a specific box outlining sites to avoid.

Good to have that flagged.

What about for infants?

Are the preferred sites different?

Yes, they can be.

In infants, peripheral veins can be quite small and tricky to access, so veins in the scalp.

The scalp, really?

Yes, and also the top, the dorsal aspect of the feet may be considered suitable sites for IV insertion in infants.

Wow, okay, that's important for pediatric care.

Are there any other site -related things for adults we should keep in mind?

Definitely.

As much as possible, you should try to avoid inserting an IV right in an area of elbow flexion, like the bend of the arm.

Because bending the arm kinks the tube.

Exactly, bending the joint can easily kink the catheter, block the flow, and really increase the chance of infiltration.

Also, super important, never take a blood pressure reading on an arm that has an active IV running.

And if a client has physical restraints, make sure they aren't positioned directly over the IV site.

That could put pressure on it and cause problems.

What if you have to use a site near a joint?

If a site in an area of flexion is just unavoidable, the healthcare provider might prescribe an arm board to help keep the limb straight and prevent the catheter from getting blocked or pulled out.

But really, the key takeaway is that forearm veins are usually the first choice for adults because of that bone support.

Okay, good summary on site selection.

Now let's discuss the actual process of administering these IV solutions.

What are the absolutely essential steps?

The very first, most critical step is to meticulously verify the IV solution against the primary healthcare providers, the PHCP's written order.

Double check everything.

Triple check.

You need to confirm the type of solution, the total volume to be infused, the percentage or concentration of any additives, and the prescribed rate of flow.

This is fundamental medication safety.

Always follow the seven rights of medication administration.

Right patient, right drug, right dose, right route, right time, right documentation, right reason.

Got it.

Exactly.

Beyond just the order, you also need to do a thorough assessment of the client's overall health status, any pre -existing conditions.

What are you looking for specifically?

You're looking for any potential contraindications, maybe allergies to the antiseptic cleaning solutions like chlorhexidine or iodine, or to the adhesive in the dressing, or as we just discussed, latex.

You also need to verify the compatibility if multiple IV solutions or medications are running at the same time.

Compatibility is key if you're mixing things.

Absolutely.

Maintaining a sterile environment is obviously crucial too.

Goes without saying, almost.

Well, it needs saying.

Thorough hand hygiene soap and water or alcohol rub followed by strict sterile or clean technique for each step is essential to minimize infection risk.

Okay, so when preparing a new IV solution for infusion, what's the correct procedure?

Walk us through that.

All right, before you even touch the new bag or bottle, make sure the IV tubing is clamped shut.

Stop the flow first.

Right, prevents accidental spills or flow.

Then, carefully take the protective cover off the spike end of the tubing and firmly insert it into the designated port on the IV fluid container.

Yep.

Once it's connected, the next critical step is priming the tubing.

Getting the air out?

Exactly.

You open the clamp and let the solution flow through the entire length of the tubing, pushing all the air out.

You absolutely don't want to infuse air into the client's vein.

Makes sense.

How often should the actual IV site, the spot on the arm, be changed for a peripheral fair?

Current guidelines, like from the CDC and standard facility policies, generally recommend rotating the peripheral IV site and inserting a new one every 72 to 96 hours.

Three to four days.

Roughly.

But of course, if you see any signs of complications at the site, redness, swelling, pain, drainage, you take it out immediately and start a new one somewhere else, sooner than that schedule.

And the dressing over the site.

The IV dressing should be changed whenever it gets wet, soiled, loose, or according to your agency's policy.

Usually that's every 48 to 72 hours for gauze dressings, maybe five to seven days for those clear, transparent film dressings.

And are there rules about how long an IV bag can hang once it's started?

Yes, and it's a crucial infection control measure.

You should not let an IV bag or bottle hang for longer than 24 hours from the time it was spiked.

Why only 24 hours?

Because the longer it hangs, the greater the risk of bacteria getting into the solution and contaminating it.

That could lead to a serious bloodstream infection, sepsis even.

Yikes.

Okay, and on a related note, take care to prevent the IV tubing from touching the floor or other contaminated surfaces, another potential source of bacteria.

Good point.

Finally, regarding the role of LPNs or LVNs in IV administration, what are the key takeaways from the chapter?

Well, the scope of practice for LPNs, LVNs, regarding IVs, specifically giving IV meds and starting lines can vary quite a bit.

It depends on the state's Nurse Practice Act and also the policies of the specific healthcare facility.

So it's not the same everywhere.

Definitely not.

Some states and facilities might allow LPNs, LVNs to give certain IV meds under RN or physician supervision, while others might be more restrictive.

The chapter specifically points to the section on priority nursing actions for instructions on removing a peripheral IV line, which is generally within the scope for most LPNs, LVNs.

Oh, check your local rules and facility policy.

Absolutely essential for LPNs, LVNs to know exactly what their state and facility allow regarding IV therapy.

Okay, let's dig into those priority nursing actions then, specifically for safely removing a peripheral IV line.

What are the critical steps?

All right, step one, always verify you have a PHCP order to actually discontinue the IV.

Check the order first, always.

Always.

Once confirmed, explain the whole removal procedure clearly to the client, make sure they understand, and ask them to keep their arm as still as possible.

Prep the patient.

Right.

Next, clamp the IV tubing to stop any flow.

Then,

carefully remove the dressing and any tape holding the catheter.

And here's a key point.

Stabilize the catheter hub with one hand while you peel off the tape with the other.

Why stabilize it?

To prevent accidentally pulling or yanking on the catheter while removing the sticky tape, that could hurt the vein.

Okay, dressing off hub stabilized, then what?

Take a sterile gauze pad, apply light pressure directly over the insertion site, just above where it enters the skin.

Then, gently and slowly withdraw the catheter.

Use a smooth, steady motion, keeping the hub part as parallel to the skin as possible.

Slow and steady.

Yep.

Immediately after it's out, apply firm pressure to the site with a dry, sterile gauze pad for about two to three minutes.

This stops bleeding and helps prevent a hematoma.

What if they're on blood thinners?

Good question.

If the client has a bleeding disorder or is on anticoagulants, you'll need to apply pressure for longer, maybe five minutes or more, whatever your policy says.

Okay, pressure applied, bleeding stopped.

What next?

Carefully inspect the site.

Look for any redness, drainage, or swelling.

And then, very important, examine the catheter you just removed.

Make sure the entire thing is intact, especially the tip.

You need to be sure no fragment broke off inside the vein.

Check the catheter integrity.

Critical step.

Absolutely critical.

Finally,

document everything accurately in the client's record.

The procedure itself, your observations of the site, that the catheter was intact, and how the client tolerated the removal.

Stabilizing the catheter during removal and checking the tip is intact?

Those sound like absolutely vital safety checks.

They really are.

Non -negotiable parts of the process.

Okay, let's move on to some general precautions.

When a client has an IZ line in place,

what are some key safety considerations?

The chapter highlights several important ones.

First, acknowledge that inserting the IV might cause some initial discomfort or pain.

Be honest with the patient.

Second, because you're puncturing the skin, there's always a potential risk of infection.

That break in the skin is an entry point for microbes.

Constant vigilance needed.

Always.

Third, remember that IV meds hit the bloodstream directly, so their effects are immediate.

This also means adverse reactions or allergies can happen very rapidly.

No buffer time like with oral meds.

Exactly.

Fourth, infusing fluids too quickly or giving too much volume can lead to fluid overload or electrolyte imbalances.

As a general rule, you should check the IV rate on an adult client at least hourly.

Hourly checks, got it.

And finally, be aware that certain IV solutions and medications just don't mix well.

They can be incompatible, leading to harmful reactions or making the meds less effective.

Always check compatibility.

The chapter specifically mentions being extra cautious with IV fluids for clients with heart failure.

Why is that so critical?

Right.

Clients with heart failure often have a heart that's struggling to pump effectively.

Giving IV fluids too fast or in large volumes can quickly overwhelm their circulatory system.

Leading to fluid overload.

Exactly.

That excess fluid puts extra strain on an already weak heart, potentially worsening their heart failure symptoms.

It can even lead to serious issues like pulmonary edema fluid backing up into the lungs.

So careful monitoring of the rate and their breathing is absolutely essential for these patients.

Makes complete sense.

Okay, let's delve into some of the specific complications that can pop up with IV lines.

The chapter has a whole table on this.

Let's start with air embolism.

What is it?

And what are the crucial prevention and intervention steps?

Okay, air embolism.

This happens when a bolus, a chunk of air, gets into a vein and travels through the circulation.

How does air even get in?

It can happen if a line isn't primed properly, filled with fluid to get all the air out before you connect it.

Or if connections in the tubing are loose, it can also happen during tubing or bag changes, or even when removing a central line if not done correctly.

So prevention is key.

Prevention is paramount.

Always make sure tubing is fully primed.

Check for air bubbles.

Ensure all connections are tight.

And replace fluid bags before they run completely dry so air doesn't get sucked into the line.

What if you suspect it has happened?

If you suspect an air embolism, maybe the client suddenly becomes short of breath, chest pain, confusion, the immediate priority is to notify the RN or healthcare provider right away.

Then clamp the IV tubing immediately to stop any more air getting in.

Okay, clamp the line, then what?

Position the client on their left side with the head of the bed lowered.

That's the Trendelenburg position.

The idea is to try and trap the air in the right atrium of the heart and keep it from going to the lungs.

Keep monitoring their vital signs closely and be ready for resuscitation if needed.

Left side Trendelenburg, got it.

Now catheter embolism, we touched on this with plastic cannulas.

Remind us of the key points.

Right, catheter embolism.

That's where a piece of the catheter, usually the tip breaks off during insertion or removal.

How do you prevent that?

Prevention involves carefully inspecting the catheter before you insert it.

Make sure it looks intact.

And when removing an IV, use that slow, gentle, steady technique we talked about.

Afterwards, always, always examine the removed catheter to ensure the tip is intact.

And if you suspect a piece did break off.

If you suspect a catheter fragment has embolized, first, notify the RN and the PHCP immediately.

A tourniquet might be applied high up on the affected arm or leg above the IV site, as prescribed, to try and stop the piece from traveling further.

Then what?

Find it.

Usually an x -ray will be ordered to locate the fragment, and sometimes surgery might be needed to remove it.

Okay.

Circulatory overload or fluid overload?

Another big one.

Who's most at risk and how do we manage it?

Circulatory overload happens when the body gets more IV fluid than it can handle.

People with pre -existing conditions like heart failure, kidney problems, or liver disease are at much higher risk.

Their bodies might just not be able to process the extra fluid volume effectively.

Anyone else?

Yes.

The very young and the very old are also more susceptible.

So how do we prevent it?

Prevention is key.

Carefully calculate and closely monitor the prescribed IV rate.

Using an electronic pump helps ensure accuracy.

It's crucial to assess at -risk clients for any baseline signs of fluid overload before you even start the infusion.

And during the infusion.

Monitor them frequently for developing symptoms.

Things like a rapid rise in blood pressure, neck veins bulging, JVD, a fast bounding pulse, rapid shallow breathing, shortness of breath, a moist cough, crackles in the lungs when you listen, and swelling or edema.

What if you see those signs?

If you suspect overload, immediate actions are slow the IV rate way down, just enough to keep the vein open, KVO rate, elevate the head of the client's bed, helps with breathing, keep them warm, assess their lungs and check for edema, and notify the RN and PHCP immediately for further orders.

Slow the rate, sit them up, call for help, got it.

Now electrolyte overload related to the fluid composition, right?

Exactly.

This is an imbalance caused by giving IV solutions with electrolytes too fast, or giving too much, or using a solution that's just not right for that patient's needs.

How do you avoid that?

Prevention starts with reviewing the client's recent lab results, their electrolytes, before starting the IV.

Then meticulously verify the correct IV solution and any added electrolytes against the PHCP's order.

Calculate and monitor the flow rate closely, ideally using a pump and checking its settings often.

What about additive?

If electrolytes or meds have been added to the bag, there should be a clear medication additive sticker on it.

Always monitor the client for signs of imbalance, like confusion, muscle weakness, cardiac changes, and report concerns promptly.

Any specific solutions to be wary of?

The chapter mentions being cautious with lactated ringer's solution in clients with kidney problems.

LR contains potassium, and if their kidneys aren't working well, they might not be able to clear it, potentially leading to high potassium levels, hyperkalemia.

Good point.

Hematoma formation that brews at the IV site, how does that happen and how can we minimize it?

A hematoma is just a collection of blood under the skin.

With IVs, it can happen if you accidentally poke through the back wall of the vein during insertion, or if the site keeps oozing blood after you take the IV out.

Prevention tips.

During insertion, try hard not to pierce that back wall.

Also, if you have an unsuccessful attempt, don't immediately put the tourniquet back on in the same spot.

When discontinuing, apply that firm pressure for two, three minutes, longer if needed, and elevate the arm.

What if one forms anyway?

If a hematoma develops, elevate the arm, apply pressure, and usually a cold compress is prescribed to help reduce swelling and bruising.

Document it carefully size, appearance, and your facility might require photos.

Infection, always a concern with breaking the skin.

What are the specific risks with IV lines?

Infection is a major risk because, as you said, the IV puncture breaches the skin's barrier.

It's a direct route for microorganisms into the bloodstream.

Does the risk increase over time?

Yes.

The longer an IV catheter stays in place, the higher the risk of infection.

Infections can be localized right at the site or they can become systemic, a bloodstream infection or sepsis, which is very serious.

Who's most at risk for show the infections?

Certain people are more vulnerable.

Those who are immunocompromised, like from cancer, HIV AIDS, chemo, older adults, and individuals with diabetes.

Prevention seems key here.

Absolutely.

Strict adherence to aseptic technique is non -negotiable during insertion and all maintenance.

Thorough hand hygiene, proper skin cleaning, keeping equipment sterile.

What signs should we watch for?

Monitor the site regularly for local signs.

Redness, swelling, warmth, pain, any drainage.

Also, be alert for systemic signs.

Chills, fever, feeling unwell, malaise, headache, nausea, vomiting, backache, rapid heart rate, and check their white blood cell count, if available.

Anything else for prevention?

Always inspect fluid containers for cracks, leaks, cloudiness before use.

Change tubing according to policy, usually no more than every 96 hours.

Change dressings if soiled or per policy.

Label everything site, bag, tubing with date and time.

And remember, a solution shouldn't hang more than 24 hours.

What if you suspect an infection?

Notify the RN and PHCP immediately.

The IVU will likely need to be discontinued.

Often, the catheter tip is sent to the lab for culture in a sterile container.

Blood cultures might also be drawn.

If a new IV is needed, start it in the opposite arm if possible.

Why the opposite arm?

Helps differentiate if it was just a local site infection or something systemic.

And as always, document everything meticulously, including photos if policy dictates.

Oh, and the chapter also reminds us to generally avoid dextrose solutions in diabetic clients as they can raise blood sugar.

Good reminder.

Okay, infiltration fluid leaking out into the tissues.

Signs, prevention, management.

Right, infiltration is when non -vesicant fluid, meaning fluid that doesn't cause tissue damage, leaks out of the vein.

Happens if the catheter slips out or pokes through the vein wall.

How to prevent it.

Try to avoid site's new joints, like the elbow.

Secure the cannula and tubing well with tape.

Maybe loop the tubing.

Use an arm board if the client is restless.

And keep an eye on the flow rate.

If it slows down or stops, that could be an early sign.

What do you do if it happens?

If you suspect infiltration, first, stop the infusion and remove the IV catheter immediately.

Elevate the affected arm or leg to help reduce swelling.

Apply compresses warm or cool, depending on the fluid and facility policy or PHCP order.

Anything you shouldn't do.

Don't rub the infiltrated area, that can make it worse.

Document everything, size, symptoms, what you did, client response.

Photos again, maybe?

Phlebitis and thrombophlebitis, vein inflammation, possibly with a clot, causes prevention management.

Phlebitis is just inflammation of the vein.

It can be caused by mechanical irritation from the catheter itself, chemical irritation from certain meds or fluids, or an infection.

Thrombophlebitis is when that inflammation leads to a blood clot forming in the vein.

Prevention strategies.

Use the right size cannula for the vein.

Smaller cannula in a bigger vein is often better.

Avoid tiny veins for irritating solutions.

Avoid joints and lower extremities in adults.

Secure the cannula well.

Change the site routinely every 72, 96 hours.

What if phlebitis develops?

If you suspect phlebitis, maybe the vein looks red, feels hard or cord -like, painful first step is remove the IV catheter immediately.

Notify the RN and PHCP.

Warm moist compresses are often prescribed to help with pain and inflammation.

Document, photos per policy.

If you suspect a clot, thrombophlebitis, that needs immediate reporting for further evaluation.

Okay, last complication listed, tissue damage.

This sounds like a broader category.

It is.

It covers various kinds of harm to skin, veins, subcutaneous tissue.

Can range from mild bruising to unfortunately permanent damage.

A particularly serious type is extravasation.

Extravasation.

That's when a vesicant, a substance that can cause blistering and tissue death, necrosis leaks out of the vein, or even a strong irritant solution.

This is an emergency.

Eye in emergency.

Because it can cause significant tissue destruction if not treated quickly.

You need to notify the PHCP immediately.

There might be specific antidotes that need to be injected into the area to try and limit the damage.

How do you prevent tissue damage generally?

Be gentle with tourniquets.

Avoid tapping hard on veins.

Monitor for bruising during insertion.

Check for tape allergies.

Watch the site closely during infusion for any skin changes, blistering, sloughing, or increased pain.

And if you suspect it.

Notify the PHCP right away.

Document thoroughly.

Consider photos.

The big reminder through all these complications is meticulous documentation.

What you found, what you did, how the client responded, it's crucial.

That was incredibly thorough on peripheral IVs and their complications.

Let's shift gears now to central venous catheters.

How are they fundamentally different?

Okay, central venous catheters are CVCs.

The main difference is where they end up.

Unlike peripheral IVs in the arm or hand, CVCs are inserted so the tip rests in a large central vein.

Usually the superior vena cava right near the heart.

Why go into such a large vein?

Several advantages.

You can infuse hyperosmolar solutions, very concentrated stuff that would irritate smaller veins.

You can measure central venous pressure or CVP.

You can give total parenteral nutrition, TPN.

And you can have multiple infusion ports for clients needing several incompatible meds at once.

How do you know it's in the right place?

Placement must be confirmed after insertion.

Traditionally, that's with a chest x -ray.

Some newer systems use things like passive magnets and ECG guidance if there are no contraindications.

Do they come in different types?

Yes, they can be single lumen, one channel, double or even triple lumen, three separate channels in one catheter.

And they can be inserted different ways.

Like how?

Peripherally inserted, like a PICC line that starts in the arm but goes to the central vein.

Centrally inserted, directly into the jugular or subclavian vein in the neck or chest or surgically tunneled under the skin before entering the central vein.

What's the big benefit of having multiple lumens?

The main advantage is giving multiple, potentially incompatible IV meds or solutions at the same time without them mixing.

Plus, you get multiple access points through just one insertion site, which might reduce infection risk compared to multiple peripheral IVs.

Are there specific ways the patient should be positioned for central line procedures like putting them in, changing tubing, taking them out?

Yes.

For insertion, tubing changes and removal, the client is usually put in the Trendelenberg position head down, feet up if they can tolerate it.

If not, flat on their back, supine is used.

Why Trendelenberg?

It helps engorge the veins and more importantly, increases central venous pressure.

This helps prevent air from being sucked into the circulation when the system is open, like during tubing changes or removal.

Often they'll also be asked to do the Valsalva maneuver, a bear down, like having a bowel movement while holding their breath during these open system moments, again, to raise pressure and prevent air entry.

Okay, the chapter mentions specific types of tunneled central lines, like Hickman, Broviac, Groscham, what makes them different?

Tunneled catheters are designed for more permanent long -term IV therapy, single or multi -lumen, they're inserted surgically.

A portion of the catheter is tunneled under the skin for several inches before it actually enters the vein.

What's the purpose of tunneling it under the skin?

Two main reasons, it helps anchor the catheter better and it creates a longer path from the skin exit site to the bloodstream, which is thought to reduce the risk of infection as bacteria have farther to travel.

These often have an intermittent infusion cap to keep the system closed and sterile when not in use.

How do you keep them from clotting?

Patency is usually maintained by flushing them regularly with either diluted heparin or normal saline.

The exact solution and frequency depend on the catheter type and facility policy.

What about vascular access ports, like port -a -cath or mediport?

How do those work?

Ports are another long -term option.

Unlike external catheters, these are implanted completely under the skin, usually in the chest or arm.

It's a small reservoir with a self -sealing silicone top called a septum.

So nothing's sticking out.

Right, nothing external.

They're used for patients needing long -term repeated IV therapy, like chemotherapy.

To use it, you fuel for the port under the skin, palpate it, and then access it by inserting a special non -coring needle, a hubernetl, through the skin and septum into the reservoir.

And when you take the needle out?

The septum reseals itself, keeping it a closed system.

Patency is maintained by periodic flushing, usually with diluted heparin, again, as prescribed and per policy.

And finally, PICC lines,

peripherally inserted central catheters.

You mentioned these start in the arm.

These seem really common now, especially for home care.

Yes, PICC lines are very common for long -term IV therapy weeks or months, often used in outpatient and home settings.

The basilic vein in the upper arm is a common insertion site, but others in the antecubital area can be used.

Where the tip ends up.

The catheter is threaded up through the peripheral vein until the tip terminates in the superior vena cava or subclavian vein, just like other central lines.

Any specific things to know about PICCs?

It's not unusual to see a little bleeding at the insertion site for the first 24 hours, but it shouldn't persist.

Phlebitis, inflammation of the arm vein where it's inserted, is a known potential complication.

And because the insertion site is below the heart level, the risk of air embolism during insertion or manipulation is generally considered lower than with neck or chest central lines.

We've covered a huge amount on IV therapy.

Let's switch now to the administration of blood and blood products.

The chapter outlines several different components.

Let's start with packed red blood cells, PRBCs.

What are they primarily used for?

OK, packed red blood cells.

They're mainly given to replace erythrocytes, the red blood cells, in clients who are deficient.

Think anemia from blood loss, or maybe the body isn't making enough red cells.

How quickly are they given?

Typically, one unit of PRBCs is infused over two to four hours.

It depends on the client's condition and how well they tolerate it.

And how do you know if it worked?

You look for improvement in the symptoms of anemia, less fatigue, less shortness of breath, and you'd expect to see an increase in their red blood cell count, hemoglobin, and hematocrit on follow -up lab tests.

The chapter also mentions washed red cells and leukocyte reduction.

What are those?

Right.

Washed RBCs have had most of the plasma, platelets, and Y cells removed.

They might be used for patients with a history of severe allergic or fibril reactions, or for stem cell transplant patients.

Leukocyte reduction specifically filters out or removes the white blood cells.

This can decrease the risk of certain reactions, like fever and transmission of some viruses, while still restoring oxygen carrying capacity.

OK.

Next up, platelet transfusions.

What's the main goal there?

Platelet transfusions are mainly for treating thrombocytopenia.

That's a very low platelet count.

Or for clients whose platelets aren't functioning properly, even if the count is OK.

Platelets are crucial for blood clotting.

Do they need to be cross -matched like red cells?

Generally, no.

Platelet concentrates usually have very few red cells.

So a bore cross -matching isn't typically required, though some places might still do it.

How are platelets given?

They're usually given pretty quickly, often over just 15 to 30 minutes per unit.

Effectiveness is judged by an increase in the platelet count and, hopefully, less bleeding.

Then there's fresh frozen plasma, FFP.

What does FFP provide, and when is it used?

Fresh frozen plasma is rich in clotting factors and other plasma proteins.

It's primarily used to provide these factors to clients who are deficient, maybe due to liver disease, vitamin K deficiency,

or certain bleeding disorders.

Sometimes it's used for volume expansion, too.

Does it have platelets?

No, FFP doesn't contain significant platelets.

But because it's plasma, you do need to ensure ABO and RH compatibility between the donor and recipient.

How is FFP given?

It has to be thought in the blood bank first.

Then it's usually infused rapidly, again, often over 15 to 30 minutes.

You monitor its effectiveness by checking coagulation studies like PT and PTT and seeing if hypovolemia resolves, if that was the reason for giving it.

Compatibility is obviously huge with blood.

The chapter has a table on this.

What are the fundamental principles we absolutely need to grasp?

Ensuring compatibility is critical to prevent potentially fatal transfusion reactions.

It all starts with meticulously collecting and labeling the recipient's blood sample right at the bedside when you draw it.

Bedside labeling is key.

Absolutely.

Standard procedure.

Have the client state their full name, compare it carefully to their ID band.

Many places require a second licensed person to witness this whole ID and labeling process.

Extra safety layer.

Then the lab work.

Right.

The lab determines the recipient's ABO type, A, B, AB, or O, and their RH factor, positive or negative.

They also do an antibody screen to look for any unexpected antibodies in the recipient's blood.

And the cross -match.

The cross -match is the final check.

They mix a sample of the donor's red cells with the recipient's serum.

If there's no clumping, no agglutination, the blood is considered compatible.

Remind us about universal donors and recipients.

O negative blood type is considered the universal red cell donor because their cells lack A, B, and RH antigens, so they can usually be given safely to anyone in an emergency.

AB positive is the universal red cell recipient because their plasma lacks anti -A and anti -B antibodies, so they can receive red cells of any ABO type.

And RH factor specifically.

RH positive people can generally receive either RH positive or RH negative red cells.

But critical point, RH negative people should ideally only receive RH negative red cells.

Giving them RH positive blood could cause them to develop antibodies, leading to problems with future transfusions or pregnancies.

The bottom line is always donor and recipient blood must be compatible to avoid severe reactions.

Okay, let's talk general precautions and nursing responsibilities when giving blood.

The chapter has a specific box outlining these critical points.

What are some key takeaways?

There are many crucial ones.

First, avoid infusing large amounts of cold, refrigerated blood rapidly through a central line.

It can cause heart rhythm problems.

Warm it up first.

Well, blood warmers are used in specific situations, but the point here is avoiding rapid infusion of cold blood centrally.

Second, never add medications to blood or piggyback anything else into the bloodline except one thing.

Which is?

Only isotonic normal saline, PO .9 % ACL, should ever be infused with blood, nothing else.

Got it, saline only.

To minimize bacterial risk, a single unit of blood, like PRBCs, shouldn't hang for longer than the prescribed time, usually two to four hours maximum.

And you must change the entire blood administration set, including the filter, with each new unit of blood.

New unit, new tubing.

Every time.

Also, inspect the blood bag carefully when it arrives from the blood bank.

Look for leaks, weird colors, clots, air bubbles.

Once you get it, administer it promptly, usually within 20, 30 minutes, or per policy.

Never store blood in regular unit refrigerators only in monitored blood bank fridges.

What about the infusion rate?

The rate varies depending on the product, the client's condition, the order.

Generally, infuse as quickly as the client can tolerate without signs of overload, and vital signs are crucial.

How often?

Measure vitals and listen to lungs before starting, again, after the first 15 minutes, and then at least hourly until one hour after the transfusion is done.

Report any significant changes immediately.

What about the specific protocols involving the blood bank in that critical bedside check of identity incompatibility?

Right, blood banks have strict protocols.

Blood is only released to authorized personnel.

They require the recipient's name and ID number, and keep meticulous records.

You should only transport blood for one client at a time to avoid mix -ups.

And that bedside check, you mentioned two people.

Yes, the bedside verification is the most critical safety step.

Standard procedure usually requires two licensed nurses.

They independently check the PHCP order.

Then at the bedside, they positively ID the client, ask them to state their name, compare name, DOB MRN to the ID band.

Then they meticulously compare all that info to the blood unit tag and the requisition slip.

Checking everything matches.

Everything, client info, blood type, RH factor, unit number, expiration date.

They must confirm ABO and RH compatibility between the unit and the recipient if any discrepancy is found by either nurse.

Stop right there.

Absolutely, stop.

Do not transfuse.

Notify the blood bank immediately to sort it out.

This dual check is a vital safeguard against potentially fatal ABO incompatibility errors.

There are also important things to ask the client before starting, aren't there?

Definitely.

Ask about cultural or religious beliefs that might affect receiving blood, like Jehovah's Witnesses.

Confirm informed consent is obtained and documented.

Explain the procedure, risks, benefits.

Ask about previous transfusions and any reactions they might have had.

And assessment beforehand.

Check baseline vital signs right before starting.

Assess their overall renal, circulatory, respiratory status, fluid tolerance.

And if they have a fever before you start, report it to the PHCP.

It might delay the transfusion or could mask a reaction later.

Okay, so you've done all the checks, got consent, baseline vitals.

Now you actually start the transfusion.

Key procedural steps.

Use standard precautions, maintain asepsis, assist the RN, double check the blood volume in the bag.

Use only blood -specific administration sets with that built -in filter.

Yay tubing is common, allowing saline connection.

What about pre -medication?

If the client has a history of mild allergic reactions, the PHCP might order pre -meds like acetaminophen or diphenhydramine.

Give them about 30 minutes before if oral or right before if IV.

And client teaching.

Reinforce the importance of reporting any unusual feelings immediately chills, itching, back pain, difficulty breathing, anything.

How fast do you start?

Determine the prescribed rate, but always start slowly for the first 15 minutes under close supervision.

Stay with the client.

This is the highest risk period for severe reactions.

Stay with them for 15 minutes.

Yes, if no reaction in those 15 minutes, you can usually increase the rate to what was prescribed if they're tolerating it okay.

Remember, major ABO reactions often show up within the first 50 milino infused.

Continue monitoring closely throughout, document tolerance, check labs later, document effectiveness.

Unfortunately, despite all precautions, reactions can still happen.

What are the signs and symptoms of an immediate reaction nurses need to watch for?

Immediate reactions can show up suddenly.

Look for chills, sweating, muscle aches, back or chest pain.

Skin signs like rash, hives, itching, swelling.

Cardiovascular signs like a rapid weak pulse, trouble breathing, cough, wheezing.

Skin color changes like pallor or cyanosis.

The client might feel apprehensive, anxious, report tingling, numbness, headache, nausea, vomiting, cramps, diarrhea.

It's a wide range.

And what if the client is unconscious or can't communicate?

How might a reaction show up then?

It can be more subtle.

Look for a weak pulse, sudden unexplained fever, heart rate changes, fast or slow, a drop in blood pressure, maybe visible blood in the urine, hemoglobinuria, or decreased or absent urine output, oligorhinuria.

Are there also delayed reactions that can occur later?

Yes, delayed reactions can happen days, even years later.

Signs might include unexplained fever, mild jaundice, yellowing skynies, and a drop in their hematocrit level.

But the key message is that first 15 minutes is the most critical window for acute reactions.

Stay vigilant, monitor vitals frequently throughout and after per policy.

The chapter gives specific priority nursing actions if a client is having a transfusion reaction.

Walk us through those absolutely essential steps.

Okay, number one, absolutely first step.

If you suspect a reaction,

stop P the transfusion immediately.

Stop the blood.

Instantly, don't hesitate.

Next, disconnect the blood tubing right at the IV site, but keep the IV line open.

Connect new tubing primed with normal saline and run it at a slow KVO rate to maintain access.

Keep the vein open with saline, why?

You need that IV access ready for potential emergency medications.

Makes sense, then what?

Immediately notify the PHCP and the blood bank.

Report the suspected reaction.

Stay with the client, do not leave them alone.

Monitor their signs and symptoms closely.

Things can change fast.

Check vital signs very frequently like every five minutes or as needed.

Be ready for meds.

Be ready to assist with giving any emergency meds the PHCP orders.

You're also likely need to collect lab samples, blood and urine.

The urine is checked for hemoglobinuria.

What about the blood bag?

The blood bag itself, all the attached tubing, labels, and the transfusion record must be carefully sent back to the blood bank for investigation.

And documentation.

Meticulously document everything.

When the reaction started, all the signs and symptoms, every action you took, and the client's response.

The emphasis is immediate stop.

Maintain IV access with saline.

Stay with the client.

Monitor closely.

Notify everyone.

Send back materials.

Document thoroughly.

The chapter includes a critical thinking question.

The nurse is monitoring a client receiving packed red blood cells, PRBCs, who has never received a blood transfusion.

The client suddenly becomes apprehensive and complains of back pain after the first 10 minutes of administration.

What should the nurse do?

What's the right immediate action in the reasoning?

The correct action is immediate recognition of a likely acute transfusion reaction.

Apprehension and back pain, especially within the first 10 minutes in a first time recipient, are classic early warning signs, possibly of a severe hemolytic reaction.

So the priority is?

The nurse's priority is to immediately call for the RN and S .P, the transfusion.

Then, assist in changing the tubing down to the IEV site.

Keep the line open with normal saline infusion.

Notify the PHCP and blood bank immediately.

Send the blood unit and tubing back to the bank.

Collect a urine specimen ASAP.

Stay with the client.

Monitor vital signs and symptoms very closely.

Be ready to assist with any further orders until the client is stable.

That reinforces the priority actions perfectly.

The chapter finishes with practice questions.

While we can't go through each one, it seems they cover the breadth of what we've discussed.

Absolutely.

They test everything from verifying blood products and recognizing different reaction types, hemolytic, allergic, febrile, to understanding IV procedures, complications like infiltration and phlebitis, and applying safe administration principles.

The rationales provided are really helpful for solidifying understanding.

Great resource for NCLE -XPN prep or review.

Definitely.

They make you apply the knowledge to clinical scenarios, which is key.

The chapter also introduces Unit 4, Foundations of Care, Hitting Key NCLE -XPN Focus Areas, Safety, Infection Control, Standard Transmission Precautions, Med and IV Calc Proficiency, Adult Assessment Data Collection, Period Operative Care, Post -op Complications, Client Safety, Positioning, Ambulation, Cube Care.

It also highlights ambulatory care, discharge teaching, follow -up home care support.

Yeah, it really ties this content into the bigger picture of nursing practice.

And the client needs.

Learning Objective section breaks it all down according to the NCLE -XPN test plan categories, safe, effective care environment, health promotion maintenance, cytosocial integrity, physiological integrity.

It really shows how fundamental this IV and blood admin knowledge is.

It truly underscores that a solid grasp of this material is foundational for safe, effective nursing care pretty much everywhere.

So to quickly recap our deep dive today, we've really unpacked intravenous therapy devices, indications, complications like infiltration, phlebitis, embolism, overload, safe administration, discontinuing lines.

Then we dove into blood administration components like PRBCs, platelets, FFP.

Compatibility testing, absolutely crucial.

Preparing for and monitoring transfusions, recognizing and managing reactions immediately.

And we touched on central lines,

PICCs, tunneled catheters, ports.

That's right, we covered a lot of ground drawing directly from that Saunders review chapter aiming to give you a comprehensive practical understanding of these vital skills.

And now for our final provocative thought.

Considering the complexity, the potential for great benefit, but also significant harm with IV therapy and blood administration.

What do you see as the single most critical responsibility for any healthcare professional involved in these procedures?

Something to mull over, that ethical dimension beyond the technical steps.

That's a great question to ponder.

As always, we encourage you to revisit sections of this deep dive if needed and keep exploring.

Thanks for joining us.

This concludes our deep dive into intravenous therapy and blood administration, covering the key concepts, guidelines, procedures, safety protocols, priority actions, and review questions outlined in the chapter.

We've aimed for complete coverage of the material presented.
