Chapter 30: Skin Conditions in Pediatric Nursing

Welcome to Last Minute Lecture.

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

These summaries supplement, not replace, the original textbook and may not be redistributed or resold.

For complete coverage, always consult the official text.

Welcome back to the Deep Dive.

We are really glad you're here.

Today, we are pulling apart something that I think a lot of us take for granted.

We're looking at the skin.

It is so easy to overlook, isn't it?

It's just there.

It's the wrapper.

Exactly.

But when you are dealing with pediatrics, and specifically when we are looking at Chapter 30 of Lifer's Introduction to Maternity and Pediatric Nursing in Canada,

the skin isn't just a wrapper.

It's a billboard for everything happening inside the child's body.

That is such a good way to put it, a billboard.

Because in PEDS, the skin is often the first alarm bell.

It can tell you about hydration, infection, nutrition, even cardiac issues.

And honestly, for new nurses or students, skin conditions are intimidating because they all look red and angry at first glance.

They really do.

I mean, distinguishing between a heat rash and a contagious fungal infection isn't exactly intuitive.

Not at all.

So, here is our mission for this Deep Dive.

We are going to conduct a comprehensive page -by -page review of Chapter 30.

We are going to take the child with a skin condition and break it down, anatomy, disorders, infections, and those critical burns.

And we aren't just memorizing definitions.

We want to get into the why.

You know, why does a baby's skin blister faster than an adult's?

Why is a kiss to make it better, potentially lethal if you have a cold sore?

Right.

Why do we care about the pH of a diaper?

Heavy stuff.

It is.

A quick disclaimer before we dive in.

We are strictly sticking to the provided text from Chapter 30.

We are looking this through the Canadian nursing context.

So, if you are listening from elsewhere, the physiology is the same, but some of the protocols might vary slightly.

Right.

Keep your textbook handy if you can, but if you are driving or on a run, don't worry.

We are going to paint the picture for you.

Okay.

So, let's start at the foundation.

Section 1.

Skin development and functions.

Now, I think most listeners know the skin protects us, but the text gets specific about three main functions.

It does.

And while protection sounds simple, you have to think about what it's actually doing.

It's a barrier against physical trauma, sure, but also chemical agents and, crucially for kids, water loss.

That's the big one, right?

Preventing dehydration.

Huge.

Then you have sensation pain, temperature, touch.

The skin is the interface with the world.

And third is secretion.

That's your sebum.

It keeps the skin texture pliable so it doesn't just crack open every time we move.

Now, right at the beginning of this chapter, there's a term that I love.

It sounds like a sci -fi force field.

The acid mantle?

It basically is a force field.

Okay.

Break that down for us.

What is the acid mantle?

So we didn't think of acid as bad or burning, but your skin, specifically the outer layer, is naturally acidic.

It sits at a pH of about 4 .5 to 6 .5.

Which is significantly lower than the neutral 7.

Right.

And there's a brilliant evolutionary reason for this.

Pathological bacteria, the bad bugs that cause infections, they generally love an alkaline environment.

They thrive when the pH is higher.

So by keeping the skin acidic, the body creates a hostile environment for those bacteria.

And chemical warfare on the surface of your skin.

Exactly.

But, and here's the clinical nugget.

We can mess this up.

How so?

If you are washing a child with harsh alkaline soaps, or if they are sitting in an alkaline substance, like urine or certain detergents,

you strip away that acid mantle, you raise the pH, and suddenly the gate is open for bacteria to invade.

I see.

That's why gentle cleaners isn't just marketing fluff.

It's about maintaining that pH barrier.

That is a great takeaway.

Now let's talk about the structural differences.

Because a neonate is not just a small adult.

If you look at figure 30 .1 in the text, it highlights how flimsy infant skin actually is.

Flimsy is a fair word.

The epidermis, that top layer, is incredibly thin in a newborn.

What does that mean for us as nurses?

Two things.

One, they blister very easily.

Friction that wouldn't bother you or me will tear their skin.

And two, absorption.

If you put a medication or a chemical on a baby's skin,

it absorbs into their bloodstream much faster and in higher concentrations than it would in an adult.

So you have to be incredibly careful with topical creams.

Incredibly careful.

You can inadvertently overdose a baby with a topical ointment because that barrier is so permeable.

The text also mentions subcutaneous fat.

Or, I guess, the lack thereof.

Right.

Neonates have very little fat under the skin.

And since fat is insulation, this is why thermoregulation is such a nightmare in the NICU or the nursery.

They just can't stay warm.

They lose heat rapidly.

Plus, the text notes their water content is higher, so they are prone to bacterial infection because bacteria love moisture.

Okay, so there are two terms regarding newborn skin that always come up on exams.

Vernix Casiosa and Lanuco.

The cheese and the fur.

Yeah.

Gross.

But accurate.

Vernix Casiosa is that white cheese -like coating you see on a newborn.

It looks messy, but it's actually a high -tech wetsuit.

Oh, wait.

It develops in the womb to protect the fetus's skin from the amniotic fluid.

If they didn't have it, they'd come out looking like they stayed in the bathtub for nine months, macerated and waterlogged.

That makes perfect sense.

And Lanuco?

That's the fine downy hair.

Yeah.

It usually shows up around 13 to 16 weeks gestation.

By the time they are born, a lot of it might be gone, but you'll often still see it on the shoulders or back, especially in preemies.

And it just goes away on its own.

Yep.

It sheds gradually.

Fast forwarding a bit, the text jumps to adolescence.

Puberty hits, and the skin changes again.

It's the awakening of the glands.

The abocrine glands, which are in the axillae, you know, the armpits and groin enlarge and become active.

Hello, body odor.

Hello, body odor and hello, acne.

The sebaceous glands ramp up sebum production, which we will talk about in depth when we get to the acne section.

Okay.

But the text makes a really important point here that isn't biological.

It's psychological.

Yes, the psychosocial impact.

We cannot underestimate this.

The text explicitly states that skin integrity is tied to self -esteem.

Absolutely.

Whether it's a teenager with acne or a child with a birthmark on their face, the psychological toll can be just as severe as the physical symptoms.

As nurses, we aren't just treating the rash.

We are treating the kid who is embarrassed to go to school.

That's a perfect segue into section two, skin disorders.

Let's say you are walking into an exam room.

How does Lifer suggest we start the assessment?

You need to use your eyes and your hands.

You are looking for color, texture, moisture, and turgor, and you need to do it in good light.

The text mentions natural daylight is best.

It is.

Fluorescent hospital lights can distort color, making jaundice or pallor harder to catch.

That's a good tip.

And speaking of light, have you ever used a wood's light?

That's the black light thing, right?

Essentially, yes.

It's a UV lamp.

The text flags this as a key diagnostic tool.

You shine it on the skin in a dark room.

Normal skin just looks, well, dark.

But if something's wrong.

But if there is a fungal infection, for instance, it might glow fluorescent green.

It's a quick, non -invasive way to spot certain organisms.

Okay, let's get into the vocabulary.

This is the part of nursing school where you feel like you're learning a new language.

Box 30 .1, we need to be able to document exactly what we see.

I'm going to throw a term at you, and I want you to give me the visual paint -the -picture for the listener.

Let's do it.

First one, McCool.

Flat.

Totally flat.

If you run your finger over it, you feel nothing.

It's just a changing color.

Like a freckle.

Exactly like a freckle or a flat mole.

Okay.

McCool?

Now we have elevation.

It's a solid raised bump,

but there's no fluid inside.

Just a bump.

Think of a pimple before it comes to a head, or a mosquito bite initially.

Vesicle.

This is a blister.

It is elevated, but it is filled with clear fluid.

Furious fluid.

If you plopped it, water would come out.

Chicken pox!

This is the hallmark of chicken pox, or a cold sore.

Yep, costule.

The name gives it away.

It's a vesicle that has gone rogue.

Instead of clear fluid, it's filled with pus.

It looks creamy or yellow.

This is classic acne or impetigo.

A wheel is irregular.

It's raised, usually red, and often changes shape.

Think of a hive.

Or a really bad mosquito bite that swells up.

It's usually a sign of an allergic reaction.

Okay, ecumosis.

Just a fancy word for a bruise.

Simple enough.

Black and blue.

It's blood trapped under the tissue.

And finally, crust.

A scab.

It's dried body fluids.

Blood, pus,

serum hardening on the surface.

Knowing those distinctions is so important because red rash tells the doctor nothing.

Nothing.

But generalized macular rash versus cluster of vesicles, that tells them everything.

Exactly.

Your documentation is legal evidence.

You have to be precise.

Let's talk about things babies are born with.

Congenital lesions.

The text spends a good amount of time comparing two specific red birthmarks.

The strawberry nevus and the port wine nevus.

And confusing them can cause a lot of unnecessary panic or false hope for parents.

So let's look at the strawberry nevus first.

Figure 30 .3.

What are we seeing?

So this is a hemangioma.

It consists of dilated capillaries.

It's usually bright red.

And crucially, it is elevated.

It sticks up off the skin.

And what is the prognosis for that?

This is the good one, generally speaking.

It might get bigger initially, which can scare parents, but then it starts to blanch and shrink.

The text says about 60 % are gone by age 5 and 90 % by age 9.

So the treatment is waiting?

Benign neglect.

Pretty much.

We don't touch them unless they are near the eye and affecting vision or if they become ulcerated.

But usually you just reassure the parents it will fade.

Okay.

Contrast that with the port wine nevus.

Figure 30 .4.

Totally different story.

A port wine stand is caused by dilated dermal capillaries too, but the lesion is flat.

It's purple pink.

Like the name suggests.

Exactly.

It looks like someone spilled wine on the skin.

And does it fade?

No.

And that is the hard conversation you have to have.

It does not disappear.

In fact, the text notes it often darkens as the child gets older.

It's permanent.

So what are the options?

You can try laser surgery to lighten it, but you can't promise it will vanish like the strawberry nevus.

That's a vital distinction.

Before we leave this section, the text lists some systemic manifestations.

Basically clues on the skin that signal deeper trouble.

Yeah, this is where the skin plays detective.

There are three big associations the text wants you to know.

Number one, café au lait spots.

These are light brown patches, the color of coffee with milk.

Having one or two is normal.

Okay.

But if a child have a lot of them, usually six or more, it is strongly associated with neurofibromatosis, which is a genetic disorder affecting the nervous system.

Got it.

Number two, the butterfly rash.

This is a red rash that spans across the nose and cheeks in the shape of a butterfly.

That is the classic textbook sign of systemic lupus erythematosus, SLE.

So if you see that, you're thinking autoimmune.

You have to be thinking autoimmune, yes.

And number three, a horseshoe -shaped scaling around the mouth.

This one is super specific.

If you see scaling or redness that forms a horseshoe around the lips, consider a zinc deficiency.

In infants, this can sometimes happen with severe diarrhea or malabsorption issues.

All right.

Let's move into the stuff that floods pediatric clinics.

Section three, common skin conditions.

We are talking about the daily struggles of parenting.

Let's start with miliaria, also known as prickly heat.

I feel like every baby gets this at some point.

What is actually happening here?

It's a plumbing issue.

The sweat glands aren't fully mature and they get blocked.

If it's hot or if the baby is bundled up like an onion, sweat gets trapped.

The follicle gets inflamed and you see these tiny pinhead sized papules.

And because parents are often terrified of their baby getting cold, they tend to overdress them.

Exactly.

The text explicitly blames overdressing here.

The fix isn't a fancy cream.

It's mechanical.

Just take off the layers.

Take the clothes off.

Let the skin breathe.

A tepid bath can help, but mostly just stop overheating the kid.

Which brings us to intertrigo.

A fancy name for chafing.

This happens in the folds, the neck, the groin, the fat rolls on a chubby baby.

It's moisture plus friction, right?

Right.

Urine, feces, sweat, it all collects in those creases.

The skin gets red and weepy.

The key here is to keep those folds clean and dry.

Okay.

But, and this is a big but, the text warns that this moist, warm environment is a five -star hotel for Candida.

Yeast.

Yes.

If that chafing gets infected with yeast, simple drying won't work anymore.

You'll need an antifungal.

This is the perfect bridge to the heavyweight champion of baby problems.

Diaper dermatitis.

The dreaded diaper rash.

The text breaks down the pathophysiology really well.

It's not just poop is bad.

It's a chemical reaction.

It is.

Remember the acid mantle.

Yes, the low pH.

Well, urine and feces interact to create ammonia.

Ammonia is alkaline.

It raises the pH of the skin.

And when the pH goes up, it activates fecal enzymes that literally digest the skin.

Ouch.

So it's a chemical burn, essentially.

Pretty much.

And then you add the friction of the diaper and the skin just breaks down.

So the question every nurse gets asked, how do I know if it's just a regular rash or a yeast infection?

Because the treatment is totally different.

This is a crucial assessment skill.

A contact diaper rash, the regular kind, is red, irritated, but usually stays within the area the diaper touches.

And yeast.

Yeast, Candida albicans,

is beefy red.

That's the text's description.

Beefy red.

It is vivid, angry red.

And it has sharper borders.

But the smoking gun is satellite lesions.

Satellite lesions?

So you'll see the main red patch and then little red dots scattered outside the main area, like little islands or satellites.

If you see those dots, it's yeast.

Zinc oxide won't kill it.

You need Nystatin or another antifungal.

There is a specific safety warning in this section about corticosteroids.

Parents often have a tube of hydrocortisone cream lying around and think, oh, this heals rashes.

And that is dangerous in the diaper area.

The text warns against using steroid creams under a diaper.

Ah.

Why?

Because the diaper acts as an occlusive dressing.

It seals it in.

Exactly.

Heat plus moisture plus a seal.

It drives the medication deep into the skin, increasing systemic absorption.

You can actually suppress the baby's adrenal glands just by putting too much steroid cream on their butt.

Wow.

So general rule.

No steroids in the diaper zone unless a pediatrician specifically orders it and tells you exactly how much to use.

Let's talk about cradle cap.

It's a brick dermatitis.

This looks worse than it is.

It's those thick, yellow, oily, crusty scales on a baby's scalp.

Parents often panic and think it's an infection or that they aren't washing the baby enough.

But it's just overactive, sebaceous glands, right?

Basically.

It resembles eczema, but the text gives us a key way to tell them apart.

Eczema itches like crazy.

Gradle cap.

Doesn't itch.

Does not itch.

The baby is usually totally unbothered by it.

So how do we get rid of the scales?

Do we pick them?

No picking.

You can cause an infection.

The text suggests a spa treatment.

Rub baby oil into the scalp at night to soften the scales.

Then in the morning, shampoo the hair and gently brush it.

The scales will wash right out.

And it also mentions this isn't just for babies.

Right.

In teenagers, we call it dandruff.

Same mechanism.

For them, we use selenium based shampoos like Selsun Blue to control it.

Speaking of teenagers, let's move to section four.

Acne vulgaris.

I think this is probably the most emotionally charged skin condition we cover.

Without a doubt.

It hits right when self -esteem is most fragile.

The mechanism the text describes is basically a perfect storm in the poor.

It is.

You have the hormonal flux of puberty increasing sebum production.

But the ducts that carry that sebum to the surface get clogged.

And the text differentiates between two types of clogs or comedones?

Right.

You have open comedones, blackheads.

Now, pop quiz.

Why are they black?

Most people think it's dirt.

I used to think it was dirt.

It is not dirt.

It is melanin.

The pore is open to the air, and the melanin oxidizes and turns dark.

So you cannot scrub the black out.

That's a great point.

And the other type.

Closed comedones, or whiteheads?

These are the troublemakers.

The pore is blocked,

preventing the sebum from escaping.

This leads to the inflammatory process.

Now, I feel like we need to address the myths.

Because I was told a lot of things caused acne when I was a kid.

Chocolate, fries, soda.

Lifer sets the record straight.

The text says explicitly that dietary restrictions on chocolate, french fries, and colas are unwarranted.

So there's no evidence.

There is no evidence they cause acne.

That is vindication for teenagers everywhere.

It is.

But the text does mention that general health matters.

Rest, good hygiene, and stress reduction are important.

But you don't need to ban pizza.

Let's look at the treatment ladder.

It starts simple.

Routine cleansing.

But again, don't overdo it.

If you scour the face, you irritate the tissue and make it redder.

Yeah, then we get into the topicals.

Retinoids and benzoyl peroxide.

Retinoids, like tretinoin retin -A, work by basically peeling the skin to clear the blockage.

Benzoyl peroxide is antimicrobial.

It kills the bacteria.

But there is a huge nursing tip warning here about using them together.

Huge.

If a patient is prescribed both, you cannot apply them at the same time.

Why not?

They chemically neutralize each other.

So the protocol is usually benzoyl peroxide in the morning, retin -A at night.

You have to keep them apart.

That's critical information.

Now, for the really severe cases cystic acne, we turn to the big guns.

Isotretinoin or Accutane.

This is a systemic medication.

It shrinks the sebaceous glands.

It works wonders, but the side effect profile is scary.

What are we watching for?

The biggest one is teratogenicity.

It causes severe birth defects.

The text outlines a mandatory program for female patients.

You need two negative pregnancy tests before you even pick up the first pill.

You need monthly pregnancy tests during treatment, and you must use two forms of birth control.

And this isn't a suggestion.

It's a requirement.

It is strictly enforced.

The text also notes a link to depression and suicidal ideation.

So if you are the nurse managing an Accutane patient, you aren't just checking their skin.

You are checking their mood.

You have to ask the hard questions about how they are feeling mentally.

Let's shift gears to a viral condition.

Herpes simplex type I.

We usually call these cold sores.

This is a virus that stays with you.

Once you're infected, the virus lies dormant in the body and flares up when the immune system is stressed.

What triggers a flare up?

The text lists the usual suspects.

Stress, sun exposure, fever, and menstruation.

And when is it contagious?

When the vesicle is forming and active, it takes about 10 days to heal.

We treat it with topical acyclover, which can shorten the duration.

But the most important part of this section isn't the treatment.

It's the warning for parents.

The kiss of death.

It sounds dramatic, but it's real, isn't it?

It is.

The text explicitly warns.

Do not kiss infants if you have a cold sore.

Do not kiss anyone with an open wound or an immunocompromised child.

Herpes simplex can cause a systemic, life -threatening infection in a newborn.

Wow.

Parents need to be taught that saying no kissing is a valid medical boundary.

That is something every maternity nurse needs to tell new parents.

Let's move to section six.

Infantile eczema or atopic dermatitis.

Eczema is fascinating because it's rarely just a skin problem.

It's an immune system problem.

The text talks about the atopic triad, which is eczema, asthma, and hay fever.

If a child has one, they're statistically likely to have the others.

It's all part of a hypersensitive constitution.

What is physically happening to the skin to make it look like that?

The process is called spongiosis.

The cells in the dermis break down and form fluid -filled spaces like a sponge.

That creates the vesicles.

Then, because it is insanely witchy, pruritus, the child scratches.

And the scratching makes it worse.

The scratching leads to lichenification.

The skin gets thick, coarse, and leathery.

It's a vicious cycle.

Itch, scratch, damage, more itch.

There has been a massive shift in how we think about preventing this, specifically regarding food allergies.

Yes.

The text outlines the current guidelines, which are almost the opposite of what we used to say 20 years ago.

We used to say, avoid allergens.

Right.

Now the research says, do not delay solids.

Introduce peanuts and cooked eggs around six months.

The idea is to teach the immune system to tolerate them.

Exactly.

Avoiding them actually seems to increase the risk of developing an allergy later.

And they also note that breastfeeding offers some protection.

So for the child who already has eczema, what is our nursing goal?

Hydrate the skin and stop the itch.

Let's talk about the bath, because water can be drying if you're not careful.

It can.

The text recommends emollient baths using oatmeal or cornstarch baking soda.

But here is the specific technique you need to teach parents.

If you're using bath oil, do not put it in the water immediately, because oil floats.

It coats the skin and prevents the water from hydrating the tissue.

Oh, okay.

You let the child soak for a while first so the skin absorbs the water.

Then you add the oil to seal that moisture in.

That is a brilliant practical tip.

What about clothing?

Cotton is the only way to go.

Wool is a major irritant, and you have to keep their fingernails short to minimize damage from scratching.

In severe cases, the text even mentions using elbow immobilizers, little splints, to physically stop an infant from scratching their face.

Let's move into the bacterial infections.

Section seven, we are talking staph and strep.

These are the opportunists.

Staphylococcal infection is common.

In a newborn, you might see it around the umbilical cord stump or a circumcision site.

And the big fear is MRSA.

Methicillin -resistant Staphylococcus aureus.

If a child has this, they are in strict contact isolation.

Gowns, gloves, the works.

There is a condition described here that sounds like a horror movie.

Scalded skin syndrome.

It looks horrific.

It's caused by S.

aureus.

The bacteria release a toxin that causes the skin to literally peel off in sheets.

The underlying tissue is bright red and looks like it has been scalded with hot water.

The text notes a very serious risk of misdiagnosis here.

Yes, because it looks like a burn.

It can be mistaken for child abuse.

You have to be very careful with your assessment to differentiate a bacterial toxin from an inflicted injury.

That's a heavy responsibility.

It is.

The good news is with antibiotics, it usually heals without scarring.

Then there is impetigo.

This is the one every school nurse knows.

Impetigo is the definition of contagious.

What's the visual hallmark?

The honey -colored crust.

It starts as red papules.

They turn into vesicles.

They burst.

And then you get this sticky honey -colored scab.

It's usually around the nose and mouth.

And the treatment involves a lot of work for the parents.

It does.

You can't just slap cream on top of the crust.

The antibiotic, like Bactroban, can't penetrate the scab.

So you have to wash the lesions with warm water and soap three or four times a day to gently remove the crusts.

And then apply the ointment?

Then you apply the ointment.

And there is a safety alert here about recurrence.

If a kid keeps getting impetigo over and over...

Check the nose.

The caregiver, or the child, might be a nasal carrier of S.

aureus.

The bacteria lives in the nose and they keep reinfecting themselves.

You might need to treat the nostrils with muperosin to break the cycle.

Moving to section 8, fungal infections.

The tinius.

Tinea is the Latin word for worm.

Hence, ringworm.

But I have to say it again.

It is 100 % a fungus, not a worm.

Right.

We name them by body part.

Let's run through them.

Tinea capitis.

Ringworm of the scalp.

You look for patches of alopecia hair loss.

The hair breaks off at the root.

Can you treat this with a cream?

Usually, no.

The fungus is deep in the hair follicle.

You need oral medication.

Specifically, greasofulvin.

And there's a trick to that one, right?

Yes.

Here's a pharmacology tip.

Greasofulvin is absorbed better with fat.

So you tell the parents to give the med with a high -fat meal, like peanut butter or whole milk.

Tinea corporeis.

Ringworm of the body.

This is the classic oval ring with a clear center and a scaly border.

The text notes that infected pets are often the source.

So check the dog.

Check the dog or the cat, yeah.

Phneopetus.

Athlete's foot.

Itchy.

Peeling skin between the toes.

The nursing focus here is hygiene.

Clean cotton socks.

Well -ventilated shoes.

Fungi hate fresh air.

Cantina cruis.

Jock itch.

Inner thighs and scrotum.

Same principle.

Keep it clean and dry.

Section 9.

Pediculosis.

Lice.

I feel itchy just saying it.

It's a rite of passage for elementary school, but there is a lot of misinformation here.

First, how do we tell it apart from dandruff?

The flick test.

Dandruff flakes off when you flick the hair.

Knits the lice eggs are cemented to the hair chef.

They do not move.

They are silvery and pearly.

The treatment is pediculocides, like permethrin, which is often sold as nicks.

Right.

It kills the live lice and most knits.

But you almost always have to retreat in 7 to 10 days to catch any eggs that hatched after the first treatment.

Now, school policy.

This is where parents get really heated.

No -knit policies.

The text is very clear on this.

No -knit policies where a child cannot return to school until every single egg shell is gone are not recommended.

Why not?

Because knits are just shells.

Many of them are empty or dead.

If the child has been treated, they are likely not contagious.

Keeping them out of school causes academic loss and social stigma.

And the other big myth.

And importantly, lice are not a find of being dirty.

They actually prefer clean hair.

That is a myth we need to keep busting.

Moving to section 10, scabies and bed bugs.

Scabies is nasty.

It's caused by the itch mite,

Sarcoptis scabii.

The female mite burrows under the epidermis to lay eggs.

That sounds horrific.

It causes intense itching, especially at night when the mites are active.

You might see thread -like burrows between the fingers or on the wrists.

And the treatment protocol is aggressive.

It has to be.

If one person has it, the whole house is greeted.

Even if Dad says he doesn't itch, he gets the permethrin cream.

It stays on for 8 to 14 hours, then washes off.

And all the laundry.

You have to wash every sheet and towel in hot water.

And bed bugs.

The text notes they are making a comeback due to travel.

They don't live on the person.

They live in the mattress or furniture.

They come out at night, bite, and leave.

How do you know there's bed bugs?

The bites often appear in a line.

Breakfast, lunch, and dinner.

And they might not show up for up to 14 days.

The treatment is extermination.

You have to heat treat the home.

Okay, we have arrived at the final and most complex section.

Section 11, injuries specifically burns.

This is a massive topic in pediatrics.

Burns are a leading cause of accidental death in the home.

Why are children so much more vulnerable than adults?

The text lists three physiological reasons.

First, thin skin.

We talked about this.

A cup of coffee that causes a mild burn on an adult can cause a full thickness burn on a child because their protective layer is so thin.

Second.

Body surface area, or BSA.

A child's head is huge relative to their body.

They have a larger surface area for their weight.

This means when they get burned, they lose massive amounts of fluid and heat compared to an adult.

Oh, there's dirt.

Metabolic rate.

Kids run fast engines.

They need high calories just to grow.

When they are burned, their metabolic rate skyrockets to heal.

They need massive amounts of protein and calories to prevent their body from breaking down its own muscle.

Let's review the classification.

We used to say first, second, third degree.

Now we use thickness.

Superficial, which is like a first degree, is epidermis only.

Like a sunburn.

It hurts.

It's red, but it blanches.

Partial thickness.

The second degree.

This involves the dermis.

This is the blister brun.

It is moist, pink, and incredibly painful because the nerve endings are exposed, but alive.

Okay, so then full thickness.

The third or fourth degree.

This goes through the dermis to the fat, muscle, or bone.

The tissue looks tough, leathery, maybe black or brown, and the most critical assessment finding, it is painless.

That confuses people.

How can a severe burn be painless?

Because the nerve endings are destroyed.

If a patient looks at a charred arm and says, it doesn't hurt, that is a very bad sign.

It means it's a full thickness burn.

Let's talk emergency care, immediate response.

Stop the burning process.

Stop, drop, and roll.

For electrical burns, there is a special warning about the iceberg effect.

What is that?

With electricity, what you see on the skin, the entry and exit wound, is just the tip of the iceberg.

The current traveled through the body.

It cooks the deep muscle, and crucially, it disrupts the heart's electrical system.

So even if the skin looks okay, the heart might not be.

Exactly, you have to monitor the ECG for cardiac arrhythmias.

You need to look for both an entry and an exit wound.

For thermal burns, what is the rule about home remedies?

Butter, oil.

No butter, no oil, no ointments on major burns.

It traps the heat and it introduces bacteria,

just cool water.

Once the child is hospitalized, what is the priority?

Airway first, always.

But then, fluid resuscitation.

Because of that fluid shift we mentioned, Plasma leaks out of the vessels into the tissue.

The blood gets thick, the blood pressure drops, and the kidneys stop working.

So you have to pump fluids in.

You have to pump fluids in fast to prevent shock.

How do we know if we're giving enough fluid?

We don't just guess.

We measure urine output.

That is the gold standard.

For a child over two, you want 20 to 30 millimiles per hour.

If they aren't peeing, you aren't giving enough fluid.

The text mentions a specific complication called a curling ulcer.

What's that?

This is a stress ulcer in the stomach.

The body is under so much physiological stress from the burn that the stomach lining breaks down.

We prevent this by giving antacids, or H2 blockers, proactively.

Let's talk about worm care.

To bridemaid, it is key removing the dead tissue, the escher, so healthy skin can grow.

It's painful, so pain management is vital.

We use silver -based dressings like sylvodine because they fight infection.

And grafting.

When the burn is too deep to heal, we need new skin.

There are three terms to know here.

Autographed.

This is the gold standard.

Taking skin from the patient's own unburned thigh and moving it to the burn.

It's permanent.

But if they don't have enough healthy skin yet...

We use temporary recovers.

Homograft is from a human cadaver.

Xenograft, or heterograft, is usually from a pig.

These act as biological bandages to protect the wound and prevent fluid loss until the patient is ready for an autograft.

We also have to touch on the dark side of this topic.

Child abuse indicators.

Figure 30 .18 in the text shows this pretty clearly.

It is a difficult reality.

Nurses are mandatory reporters.

You have to look at the pattern of the burn.

What differentiates an accident from abuse?

An accidental scald, like pulling a pot off the stove, usually has a splash pattern.

It's irregular.

Droplets.

An inflicted scald, where a child is held in hot water, has sharp lines of demarcation.

The glove, or stalking burn.

Exactly.

It looks like they are wearing a red glove.

That means the hand was submerged and held there.

That is a massive red flag.

Or burns on the buttocks in a donut shape, meaning they were held down in a tub.

It's crucial to recognize those signs.

Finally, section 12, sunburn and frostbite.

Sunburn prevention is the main story.

SBF 30 -plus applied every two hours.

But the text has a specific rule for infants.

Under six months.

No sunscreen.

Their skin is too absorbent.

Use hats, shade, and clothing instead.

And frostbite.

Freezing of the tissue.

The extremity looks pale, hard, and has no sensation.

The nursing challenge is the rewarming.

Because it hurts.

A lot.

It hurts excruciatingly.

As the blood returns, you get a deep purple flush and severe pain.

You have to medicate for pain before you start rewarming.

And you never rub it.

Right.

Never massage the frozen area.

Ice crystals in the cells act like shards of glass.

And will destroy the tissue if you rub it.

That brings us to the end of chapter 30.

We've covered everything from diaper rash to third degree burns.

It's a lot of material.

But if you step back, the themes are consistent.

Skin is a vital barrier.

Kids are structurally different than adults.

Thinner skin.

Different surface area.

Infection control involves the whole family.

And whether it's acne or a burn, there's always a psychological component to skin conditions.

That's a wrap for this deep dive into chapter 30.

This has been the last minute lecture team helping you ace that exam.

Good luck with your studies.

Thanks for listening.
