Chapter 7: Nursing Care of Mother and Infant During Labor and Birth

Welcome to Last Minute Lecture.

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

Usually when we talk about medical diagnostics, there's this comforting expectation of absolute precision.

It's like engineering.

You break your arm, the x -ray shows that jagged white line, the doctor points to it and says, you know, there it is.

Right.

It's very binary.

Broken or not broken.

You can just point directly to the problem.

Exactly.

It's clean.

But then you step into the world of maternity care.

You walk into a delivery room and suddenly you realize that imaginary x -ray machine is, well, it's completely useless.

We are looking at a diagnostic and clinical landscape that is incredibly murky.

You aren't just looking at one system.

You're managing a cascading complex physiological event where the raw mechanics of the human body just kind of collide with the absolute unpredictability of human emotion.

Oh, it is the ultimate definition of clinical muddy waters.

I mean, and that complexity is exactly why we're doing this.

Which brings us to today's mission.

Welcome to the deep dive.

Today we're doing a special last minute lecture deep dive and we were talking directly to you.

Yes, you, the nursing student listening right now, who is prepping for a massive maternity exam or maybe about to step onto the floor for your very first clinical rotation in labor and delivery.

So consider this your personalized one -on -one tutoring session.

We're taking the dense material from chapter seven of Lifer's Introduction to Maternity and Pediatric Nursing and we are going to extract the core mechanism so that this information actually sticks in your brain.

Yeah.

And to really make it stick, we have to establish the foundational philosophy of this material.

The central concept here is that childbirth is a normal physiological process.

It is not inherently a disease state.

However, the bedside nurse has a profoundly unique responsibility in this environment because you are caring for two patients at the exact same time, the mother and the fetus.

Wow, right?

Two patients at once.

Exactly.

You are the vital bridge standing between highly sophisticated medical monitoring technology and the very real physical and psychological needs of those two lives.

So if we are the bridge, let's start building it from the ground up because before a single contraction even happens, before we hook up any monitors, we have to look at the environment

because the setting and the cultural lens completely dictate how a patient experiences this whole event.

Absolutely.

The environment sets the baseline.

From a cultural standpoint, you must understand that a patient's background defines their definition of birth.

Do they view it as a medical illness requiring intervention or is it a completely natural holistic time?

Is this a highly private event or a public family gathering where everyone is in the room?

As a nurse in a multicultural environment, you have to throw the word routine right out the window.

Because you can't just make assumptions based on how they look or where they are from.

Never.

You have to ask open -ended neutral questions.

You find out exactly who they want in the room, what practices they value, and how they express pain because cultural expression of pain varies wildly.

That is such a good point.

And the physical room itself matters just as much, right?

When you look at the options for where to give birth, there's a real spectrum.

The most common is the hospital setting, usually in an LDR, so a labor delivery and recovery room, or an LDRP where they also stay for postpartum.

And they designed these rooms to look like a cozy hotel.

Lots of wood trim, nice furniture, artwork.

But as a nurse, you know that behind those oak panels is a massive wall of essential emergency equipment.

You know, oxygen and suction.

Right.

It's the illusion of a low -tech environment wrapped around a high -tech safety net.

Yeah.

Then you have freestanding birth centers, also very homelike, usually run by midwives, great for low -risk patients, and less expensive.

But the trade -off is critical.

If an emergency happens, there's a built -in delay while you wait for transport to a hospital.

And finally, there are home births, which I imagine require a very specific type of patient.

That's a crucial point for clinical reasoning.

Not everyone is a safe candidate for a home birth, and you need to know exactly why.

For instance, a patient with a previous cesarean section is contraindicated.

Well, because of the scar tissue on the uterus.

Precisely.

There is a real risk of uterine rupture along that old scar during intense labor, and if that happens outside of an operating room, it is catastrophic.

Other contraindications include a malpresentation, like a breech baby, or multiple gestation, like twins.

Also, if they are a primipara, meaning it's their first time giving birth.

Wait, really?

Why is a first -time mom automatically ruled out for a home birth?

Well, because her pelvis is clinically untested.

We don't actually know yet if her pelvic structure can accommodate a fetus passing through it safely.

And finally, a gestational age greater than 40 weeks is a contraindication because the placenta starts to degrade and lose its efficiency the further past the due date you go.

Okay, that makes total sense.

We aren't just memorizing rules.

We're looking at the physics and physiology of the situation,

which transitions us perfectly into the actual mechanics of labor.

In the nursing world, we talk about the four P's, the powers, the passage, the passengers, and the psyche.

Let's break down the physical side first.

The powers are the engines of birth, right?

Yeah, think of the powers as two distinct forces working together.

First, you have the involuntary engine, which is uterine contractions.

The mother cannot control these at all.

They are what actually cause the cervix to efface or thin out and dilate or open.

Second, you have the voluntary engine, which is the mother's act of pushing.

Okay, so the engine pushes the passenger through the passage, the passage being the mother's bony pelvis and soft tissues.

And the passenger is actually plural.

I mean, it's the fetus, the placenta, and the amniotic fluid.

When we assess the fetus, we look at the fetal lie.

This is basically how the baby is situated in the tight corridor of the uterus.

Longitudinal lie means the baby's spine is parallel to the mother's spine, so they're pointing up and down.

Transverse lie means the baby is lying sideways across the abdomen.

And you cannot deliver a transverse baby vaginally.

But here is where we hit the fourth P, the psyche,

the mother's mental and emotional state.

Okay, let me pause and push back on this for a second.

Because the first three Ps, you know, powers, passage, passenger, that's just pure physics.

It's forcing an object through a confined space.

I get why that matters.

But how does the psyche, a mental state, actually stop a massive muscular physical process like labor?

It sounds a bit like, you know, mind over matter manifesting.

Yeah, I get why you'd think that.

But it's not just a nice holistic idea.

It is a hardcore physiological feedback loop.

Think about what happens when a person experiences intense fear or severe anxiety.

The sympathetic nervous system flares up.

Classic fight or flight response.

Exactly.

The adrenal glands dump massive amounts of stress compounds, specifically catecholamines, into the bloodstream.

And in a fight or flight state, the body prioritizes survival.

It physically diverts blood flow away from non -essential organs like the uterus and the placenta and shunts that blood to the skeletal muscle so the person can, you know, run away.

Furthermore, those catecholamines literally bind to receptors in the uterus and actively inhibit smooth muscle contractions.

Wow.

So the terrified patient is accidentally chemically stalling her own labor and simultaneously decreasing oxygen to her baby.

Yes.

That is why managing the psyche, like diminishing fear, providing education, offering support, is a primary clinical intervention, not just a nice bedside manner.

You are actively trying to keep catecholamines out of her bloodstream.

That is fascinating.

That perfectly bridges the emotional with the biological.

So let's say the psyche is calm, the mechanics are aligning.

Well, how do we know the engine has actually started?

What are the impending signs of labor?

The body gives several warning signs before true labor hits.

You'll see lightning.

This is when the fetus settles deeper into the pelvic inlet.

The mother will often tell you she can suddenly breathe much easier because the baby isn't crushing her diaphragm anymore.

It's like the baby just dropped its heavy suitcases at the front door.

Breathing is easier, but now there's immense pressure on the bladder.

Oh yeah, constant urinary frequency.

You'll also see an increase in clear vaginal discharge, intensifying Braxton -Hicks contractions, and interestingly,

a one to three pound weight loss right before labor begins.

This is due to sudden hormonal shifts that cause the mother's body to excrete excess fluid.

And while all this is happening, the baby is starting to navigate that passage.

When we measure how far down the baby has traveled, we use the term station.

This is a clinical measurement that can be really, I don't know, counterintuitive for students.

It can be.

Station evaluates the descent of the fetal presenting part, usually the head, in relation to the mother's ischral spines, which are bony prominences in the pelvis.

The ischral spines are ground zero, station zero.

So if you think about it like an airplane descending for a landing, the ischral spines are the runway threshold.

If a patient is at a minus station, like a minus two or minus one, that means the baby's head is still up in the clouds.

It is physically higher up in the pelvis, above the spines.

But if you see positive numbers, like plus one, plus two, the baby has crossed the threshold and is actively coming down for a landing.

Positive means closer to delivery.

That's a great way to visualize it.

So with all these physical shifts, the most common question patients have is, when do I actually go to the hospital?

You have to give them hard clinical rules.

They go if their water breaks, so ruptured membranes.

They go if fetal movement decreases.

They go if there is active bleeding.

And let's clarify that.

Active, free -flowing, bright red bleeding is an emergency that is very different from bloody show, which is just a thick, mucousy pink discharge caused by the cervix beginning to soften.

Right.

Huge difference.

And finally, they go for regular contractions.

The standard rule is every five minutes for a first -time mother, or every 10 minutes if she has had a baby before.

But this brings up a huge clinical frustration, the false alarm.

Patients come in, we hook them up, and realize they aren't in true labor.

Here is my dumb question of the day.

If we determined it's just false labor, shouldn't we just say, hey, false alarm, tell them to stop stressing and send them home?

Well, the terminology false labor is actually a bit misleading.

Clinically, we prefer to call it prodromal labor.

It's not false.

It's doing real work.

Those mild, irregular contractions are actively preparing the cervix to dilate and helping nudge the fetus into a better position.

It's the warm -up before the marathon.

But how do you, as the nurse, definitively tell the difference when a patient walks through the doors?

The walking test is a great indicator.

If a patient gets up and walks around, and her contractions actually slow down or become relieved, that is prodromal, or false, labor.

Conversely, walking will intensify true labor, but the ultimate, indisputable clinical deciding factor is the cervix.

True labor always results in progressive cervical effacements of thinning and dilation, which is opening.

If the cervix isn't changing, it's not true labor.

Okay, so let's say the cervix is changing.

It's the real deal.

The patient is admitted.

When you look at the admission process, what are the absolute priorities?

Because there are a million things to do.

You focus on the big three.

First, fetal condition.

You immediately assess the fetal heart rate and the status of the amniotic fluid.

Second, maternal condition.

You get a baseline of her vital signs.

And third, impending birth.

Are we having this baby in the next five minutes?

And there is a massive clinical warning here.

You have to watch the patient's behavior.

If the mother suddenly starts grunting, if she is bearing down, sitting awkwardly on one buttock, or if she simply looks you in the eye and says, you know, the baby is coming down.

You believe her.

You never leave that room.

If you suspect an imminent precipitous birth, do not run out to the hallway to grab the doctor.

You hit the emergency call bell, you put your gloves on, and you open the precept tray because you are about to catch a baby.

Wow.

Okay, you are the front line.

Now, assuming the baby isn't arriving right that second, we shift into intense monitoring,

the clinical core of labor.

Let's talk about the fetal heart rate, or FHR.

Yeah, so the baseline for a happy oxygenated fetus is a heart rate between 110 and 160 beats per minute.

But you are constantly scanning the electronic fetal monitor for deviations, specifically decelerations, which are drops in the heart rate.

And the Y behind these drops dictates your nursing interventions.

Let's look at variable decelerations first.

On the monitor, these look like sharp, abrupt V or W shapes.

The heart rate suddenly plummets and pumps back up.

Variable decelerations are almost always caused by umbilical cord compression.

The baby is twisting or the cord is caught and it's being squeezed.

It's like someone stepping on a garden hose.

The flow just abruptly stops.

So what's your immediate intervention?

You remove the foot from the hose.

You reposition the mother.

If she is on her back, roll her to her side.

If she's on her side, roll her to the other side.

By physically moving the mother, gravity shifts the fetus.

And usually that relieves the pressure on the cord.

But then you have late decelerations.

These are incredibly insidious.

The fetal heart rate drops, but the drop happens after the peak of the mother's contraction.

And it takes a long time to recover back the baseline.

It's late.

And the cause here is much more dangerous.

Late decelerations point to utero placental insufficiency.

The placenta is like an exhausted battery.

It simply cannot deliver enough oxygen and blood to the fetus to withstand the stress of the contraction.

The fetus is suffocating.

So if I'm looking at the strip and I see late decelerations, what is the exact sequence of actions to save that fetus?

It requires rapid, decisive intervention.

First, you immediately reposition the mother to her left side to maximize blood flow back to her heart and down to the uterus.

Second, you administer supplemental oxygen to the mother.

Third, you increase her non -medicated IV fluids to boost her total blood volume.

And fourth, if she is receiving oxytocin or pedicin to stimulate contractions, you shut it off immediately.

You want to stop the contractions to give the fetus a break and buy them time to recover.

That is life -saving clinical reasoning right there.

Left side, oxygen, IV fluids, stop pedicin.

Got it.

We're also constantly checking the amniotic fluid once her water breaks.

What are we looking for there?

Normal fluid should be clear, maybe with some little white flecks of vernix, which is that skin protectant the baby makes.

But if you look and see green fluid, that means the fetus has passed meconium, its first bowel movement, while still inside the uterus.

Which is a huge red flag for fetal stress.

Right.

Exactly.

And it's dangerous because if the baby inhales that thick green meconium during birth, it can cause severe respiratory failure.

Also, if the fluid is cloudy or yellow or has a foul odor, that screams infection.

And the provider needs to know instantly.

We are tracking the baby so closely, but we also have to monitor the mother just as rigorously.

For example, her temperature.

If her temp hits 38 degrees Celsius, which is 100 .4 degrees Fahrenheit, you have to report it.

Why?

Because an elevated temp suggests an act of infection, and the team might need to start 4 -V antibiotics immediately to protect the baby from acquiring group B strep as it moves through the birth canal.

You also have to monitor the frequency of her contractions to watch for uterine tachycystal.

This is defined as having more than five contractions in a 10 -minute window.

If the uterus is spasming that fast, the placenta physically does not have time to refill with fresh oxygenated blood between squeezes.

You are suffocating the fetus by overworking the engine.

Right.

And let me throw in a deeply practical nursing tip here regarding maternal monitoring.

You must check the mother's bladder every one to two hours.

Why?

Think about the anatomy.

A distended full bladder sits directly in front of the uterus.

It acts as a literal physical roadblock.

If the bladder is full, the baby's head cannot descend.

And if the mother has an epidural, she will have zero sensation that her bladder is about to burst.

You have to be the one to check it.

Understanding that anatomy is what makes you an excellent nurse.

Which brings us to how we actually help the patient physically navigate the stages of labor, because her body is undergoing massive physiological shifts.

Right.

Think about her cardiovascular system.

If a heavily pregnant laboring patient lies flat on her back, the sheer weight of her uterus compresses the ascending vena cava and the descending aorta against her spine.

Which causes supine hypotension.

Her blood pressure will absolutely tank.

She'll feel dizzy and blood flow to the baby drops.

The nursing intervention is simple but critical.

Never let a laboring patient lie flat on her back.

Always use a wedge or encourage a side lying position.

And what about a respiratory system?

We always see patients doing paced, rapid breathing techniques to deal with pain.

But what happens if they get panic and overdo it?

They hyperventilate.

They blow off too much carbon dioxide, causing respiratory alkalosis.

You will physically see the patient's fingers cramp up and they will complain of tingling in their hands or face.

As the nurse, you have to step in, lock eyes with her, and actively coach her to slow her breathing down.

Coaching is your main job as she moves through the four stages of labor.

Let's map these out.

Stage one is dilation and effacement.

This is the marathon.

It is broken down into three distinct phases.

Latent, active, and transition.

Latent phase is one to three centimeters dilated.

The patient is usually awake, talkative, cooperative.

Then active phase, four to seven centimeters.

The contractions get serious, and the patient becomes much more inwardly focused and anxious.

But then there's the transition phase, seven to ten centimeters.

Transition is where you have to be hypervigilant about maternal behavior.

If your patient, who has been managing her pain beautifully, suddenly loses all emotional control, becomes extremely irritable, starts yelling at her partner, or demands that you just cut the baby out, you should immediately suspect she has hit the transition phase.

It is the shortest but most violently intense part of labor.

She isn't just being difficult.

Her body is an absolute physiological overdrive.

But once she survives that and hits ten centimeters dilated, she enters stage two, expulsion of the fetus.

This is the pushing stage.

But there's an incredible intervention here called laboring down.

How does that work?

Laboring down is a technique where, even though the cervix is fully open at ten centimeters, you don't immediately tell the mother to start purple pushing.

Instead, you wait.

You allow the natural involuntary uterine contractions and gravity to passively push the baby further down the birth canal over the next hour or so.

It's like, why sprint down the stairs when you can just stand on the escalator and let the machine do the work for you.

You can serve massive amounts of maternal energy for the final push.

Exactly.

Though it's worth noting, you usually only do this if the mother has an epidural and isn't feeling the uncontrollable urge to push.

Stage two concludes with the birth of the baby, but we're not done.

Stage three is the expulsion of the placenta, which usually takes five to thirty minutes.

As the nurse, you have to inspect that placenta to make sure no fragments were left inside the uterus.

And there's a great memory trick for how the placenta looks when it comes out.

Duncan is dull, meaning the rough maternal side delivered first.

And Schultz is shiny, meaning the smooth -feel side delivered first.

Once the placenta is out, we enter stage four, recovery.

This is the first one to four hours after birth.

The mother might feel like sleeping, but the nurse is on high alert.

You are taking vital signs every fifteen minutes.

You are aggressively massaging the uterine fundus, which is the top of the uterus.

It needs to feel rock hard like a grapefruit.

If it feels boggy or squishy, the uterine muscles aren't clamping down, and the mother is at severe risk for hemorrhage.

Right.

You're also checking the lochia, the vaginal bleeding, ensuring she isn't soaking through more than one pad an hour.

So you're managing the mother's survival.

But what about the baby?

This is where we shift focus to phase one, immediate care of the newborn.

We are in the first golden hour of this brand new life.

And in that first hour, your absolute undisputed priority for the newborn is thermoregulation, keeping them warm.

Now, I want to dive deep into this because it's not just about making the baby feel cozy.

Why is vigorously drying the baby with a warm towel the very first action you take the second they emerge?

Because if you don't, you trigger a lethal physiological cascade.

The infant is born soaking wet with amniotic fluid into a cold room.

If that fluid is allowed to evaporate off their skin, they experience massive heat loss.

This causes rapid hypothermia.

And newborns don't have the muscle mass to shiver to generate heat, right?

Correct.

They cannot shiver.

So to generate heat, their tiny body frantically starts metabolizing its stored brown fat and burning through its limited glucose stores.

Which instantly leads to hypoglycemia, dangerously low blood sugar, which can cause permanent neurological damage.

But the dominoes keep falling.

Because the baby's metabolic rate is skyrocketing to stay warm, their body suddenly demands significantly more oxygen.

This is a state of cold stress.

If the baby's lungs can't keep up with that massive demand for oxygen, they slip into hypoxia.

So simply failing to dry a baby leads to evaporation, which causes hypothermia, which causes hypoglycemia, which triggers cold stress, which results in hypoxia.

That is mind -blowing.

One simple physical oversight triggers a multi -system failure.

So what is the best clinical intervention to stabilize their temperature?

The single most effective method is immediate skin -to -skin contact.

You dry the baby, place their bare chest directly against the parent's bare chest, and cover them both with a warm blanket.

The parent's body acts as a perfect biological radiator, stabilizing the infant's temp better than any mechanical hospital warmer ever could.

Plus, it immediately facilitates crucial early bonding and kickstarts breastfeeding.

During that golden hour, we also do routine eye care.

The nurse applies erythromycin antibiotic ointment into the newborn's eyes to prevent ophthalmia neonatorum, which is a severe infection caused by exposure to gonorrhea or chlamydia in the birth canal that can literally cause blindness.

But the key detail here is that you deliberately wait about an hour after birth to administer the ointment.

Yes, because the ointment blurs the baby's vision.

You want to delay it just long enough so the baby has clear vision to look at their parents, make eye contact, and form that initial neurological bond.

It's all about protecting that connection.

And speaking of connection, there's a relatively new, deeply fascinating biological transfer happening during vaginal birth and skin -to -skin contact, the seeding of the microbiome.

Oh yeah, as the baby passes through the birth canal and rests on the mother's skin, they are coated in millions of protective, beneficial maternal bacteria.

This massive microbial transfer essentially boots up the newborn's raw immune system and colonizes their gut.

Which leaves us with a truly profound final thought to mull over.

Specifically regarding the concept of dysbiosis, which is the disruption of that delicate microbiome.

As a nurse, you are operating inside a highly medicalized system.

If childbirth is a beautifully orchestrated physiological process, how might our routine, well -intentioned hospital interventions be accidentally shifting things?

It's a critical question for your clinical practice.

Are unnecessary IV antibiotics or aggressively wiping the baby clean or taking the baby away to a warmer instead of doing skin -to -skin?

Are those actions accidentally starving the baby of that vital maternal bacteria?

Could a seemingly minor deviation in how we manage their first 60 minutes of life actually alter their immune system and health trajectory for decades?

It brings us right back to our starting point.

The delivery room is not a clean x -ray, it's a delicate cascading ecosystem.

You aren't just reading monitors, you are guarding the foundation of two lives.

And mastering the why behind the textbook rules is how you become the nurse those patients desperately need.

Thank you so much for studying alongside us today on this deep dive.

From all of us here in the Last Minute Lecture Team, we wish you the absolute best of luck on your upcoming exams and in your clinical rotations.

You've got this, keep diving deep.
