Some pregnancy complications cannot exist outside pregnancy. Conditions limited to pregnancy arise because of the pregnant state itself and typically improve or resolve after birth: the hypertensive disorders (, , , ), (GDM), placental bleeding conditions (, ), amniotic fluid disorders, fetal growth restriction, , , and .

The unifying idea: pregnancy changes the placenta, blood vessels, hormones, and metabolism, and in some pregnancies those changes go wrong in characteristic ways. Because the trigger is the pregnancy itself, the definitive "treatment" for many of these conditions is delivery — but delivery is not always immediately possible or safe, especially before term. Care therefore focuses on monitoring, stabilizing, and timing delivery for the best balance of risks. Nurses carry much of the monitoring and most of the education about warning signs.

Why this matters

These conditions are leading causes of maternal and fetal illness, and several are emergencies:

Preeclampsia and eclampsia are major causes of maternal morbidity and mortality worldwide. The warning signs — headache, visual changes, epigastric pain — are on every prenatal education checklist, and nurses act on them immediately.
Placental bleeding conditions can threaten both lives quickly; knowing the difference between previa and abruption drives safe nursing actions — most famously, no vaginal examination when placenta previa is suspected.
Gestational diabetes raises the risk of a very large baby, birth injury, and newborn low blood sugar — and marks the person for future type 2 diabetes screening.
Many of these conditions recur in later pregnancies and raise long-term health risks, so postpartum follow-up matters.

Core Concepts

Hypertensive disorders: a spectrum

These disorders share high blood pressure but differ in severity and organ involvement:

Gestational hypertension — new-onset high blood pressure without the other signs of preeclampsia.
Preeclampsia — gestational hypertension plus evidence the disorder is affecting the pregnant person's organs (commonly the kidneys; the definition has broadened to include other systems). It usually appears after 20 weeks. The underlying problem is thought to start in the placenta: abnormal implantation leads to a stressed placenta that releases signals injuring the mother's blood vessels.
Eclampsia — preeclampsia that progresses to seizures. A medical emergency: prevent seizures, protect the airway, emergent care.
HELLP syndrome — a severe variant: Hemolysis (red blood cell breakdown), Elevated Liver enzymes, Low Platelets. It can present with only epigastric pain or nausea.

Nursing care: monitor blood pressure, urine protein, and symptoms; institute seizure precautions; report headache, visual changes, epigastric/right-upper-quadrant pain, and sudden severe swelling; magnesium sulfate is the standard medication used to prevent seizures in preeclampsia (per orders and protocols); position for optimal blood flow; prepare for delivery when warranted. Diagnostic criteria and thresholds follow current guidelines and vary by institution — learn the concepts and follow facility protocols.

Gestational diabetes mellitus (GDM)

GDM is glucose intolerance first recognized during pregnancy. Placental hormones make tissues increasingly insulin-resistant, and when the pancreas cannot compensate, blood glucose rises. It typically appears in the second half of pregnancy, is screened for around 24–28 weeks, and usually resolves after birth — but it is a strong marker for future type 2 diabetes, so postpartum screening is recommended. Management centers on nutrition, physical activity, and glucose monitoring, with medication added per the care team's plan when targets are not met.

Bleeding conditions: placenta previa and placental abruption

Placenta previa — the placenta implants over or too near the cervical opening. Classic presentation: painless bright red bleeding in the later half of pregnancy. A vaginal examination is contraindicated when previa is suspected because it can trigger hemorrhage. Diagnosis is by ultrasound; management involves monitoring and a planned cesarean birth (per the care plan) because the placenta blocks the birth canal.
Placental abruption — the placenta separates from the uterine wall before delivery. Classic presentation: painful bleeding with a rigid, tender uterus, often after trauma or in hypertensive disorders. Abruption can be concealed, so pain and uterine rigidity matter even without visible blood. It is an emergency: monitor maternal vital signs and fetal status, position for blood flow, prepare for rapid intervention.

The contrast to remember: previa = painless bright red bleeding; abruption = painful bleeding with a tense uterus.

Fetal growth restriction and amniotic fluid disorders

Fetal growth restriction (FGR) — the fetus grows below the expected trajectory; detected by serial ultrasound. Causes include placental insufficiency and maternal conditions. Nursing care: monitoring, fetal-movement awareness, growth follow-up.
Oligohydramnios (too little fluid) — associated with cord compression and sometimes fetal kidney/urinary problems.
Polyhydramnios (too much fluid) — associated with multiple gestation, maternal diabetes, and some fetal conditions; excess fluid can press on the diaphragm. Report sudden abdominal-size changes or breathing difficulty.

Hyperemesis gravidarum

Severe, persistent nausea and vomiting — far beyond "morning sickness" — causing dehydration, weight loss, and electrolyte imbalances. Treatment may include IV fluids, antiemetics (per order), and nutritional support. Nurses assess intake/output and weight trends and teach about triggers and small frequent meals. It usually improves as pregnancy progresses.

Intrahepatic cholestasis of pregnancy

A pregnancy-specific liver condition marked by intense itching — often on the palms and soles — because pregnancy hormones slow bile flow; jaundice may follow. It is monitored closely because of fetal risk associations; management and delivery timing follow the care team's plan. Key nursing point: itching in pregnancy is a reportable symptom, not just an annoyance.

Preterm labor and multiple gestation

Preterm labor is regular contractions with cervical change before term. Multiple gestation raises the risk of preterm birth and of several conditions above (preeclampsia, GDM, polyhydramnios). Nursing care for threatened preterm labor: monitor contractions, fetal status, and symptoms; report per protocol; teach when to call.

The nurse's role across all of these

Screening and surveillance (blood pressure, glucose, urine, ultrasound follow-up), education about red-flag symptoms, emergency response, and postpartum follow-up — several of these conditions (GDM, hypertensive disorders) resolve at delivery but leave the person at higher future risk, including in later pregnancies.

Common Confusions

Do not confuse	With	Difference
Placenta previa	Placental abruption	Previa = painless bright red bleeding (placenta over cervix; no vaginal exams); abruption = painful bleeding with tense uterus
Gestational hypertension	Preeclampsia	Gestational hypertension is BP elevation only; preeclampsia adds organ involvement — that distinction drives urgency
Hyperemesis gravidarum	Typical morning sickness	Hyperemesis causes dehydration, weight loss, and electrolyte imbalance requiring treatment
Gestational diabetes	Preexisting (type 1/2) diabetes	GDM is first recognized in pregnancy and usually resolves after birth; preexisting diabetes was present before (see previous topic)
Preeclampsia = "high blood pressure"	A multi-system pregnancy disorder	The disease involves placenta and blood vessels, which is why it can affect liver, kidneys, blood, and brain
"Limited to pregnancy" = no long-term effects	They resolve but leave risk	GDM and hypertensive disorders signal future type 2 diabetes and cardiovascular risk
Vaginal bleeding always means a fetal problem	Some causes are placental/maternal	Bleeding can originate from placenta (previa, abruption) or cervix; the source drives the response

The same idea, in plain words

Explain it like I’m 10

Some problems only show up while a baby is growing inside — like a houseguest who only causes trouble while staying at the house. High blood pressure, pregnancy diabetes, and placenta problems are like that: they appear because of the pregnancy, and for most of them, the "fix" is the baby being born. Until then, the health care team watches closely, teaches the family what to look out for, and keeps everyone as safe as possible.

Worked example

At 31 weeks, a pregnant person arrives in triage with a "bad headache all day," "spots in my vision," and pain "right under my ribs." Her blood pressure is elevated, and she has new facial and hand swelling.

The nurse's reasoning:

Recognize the pattern: headache + visual changes + epigastric pain + elevated BP + sudden edema are textbook preeclampsia warning signs. This is not "just a headache."
Act on safety: position on the left side to optimize blood flow, institute seizure precautions (dim lights, reduce stimulation, bed rails up, emergency equipment available), and notify the provider immediately.
Support and prepare: reassure and explain, continue monitoring blood pressure and fetal status, and prepare for possible further testing, magnesium therapy (per protocol), and early delivery.
Educate: after stabilization, reinforce which symptoms should bring the person back immediately — and provide written warning-sign information if discharge occurs.

Why this works: the nurse did not wait for a diagnosis to act. The symptom constellation triggered safety measures and provider notification — the correct priority when a hypertensive emergency is possible. This is the most-tested "recognize the warning signs" pattern in maternal-newborn nursing.

Key takeaways

Preeclampsia warning signs to teach and act on: headache, visual changes, epigastric/right-upper-quadrant pain, sudden severe swelling, shortness of breath.
Previa vs abruption: previa = painless bright red bleeding, no vaginal exams; abruption = painful bleeding with a rigid, tender uterus.
HELLP = Hemolysis, Elevated Liver enzymes, Low Platelets — a severe preeclampsia variant that can present with only epigastric pain or nausea.
Eclampsia = seizures in a person with preeclampsia — a true emergency.
GDM usually resolves after birth but marks the person for future type 2 diabetes screening.
Many pregnancy-limited conditions recur in later pregnancies.
Delivery is the definitive treatment for many of these conditions, but timing is a careful risk–benefit decision by the care team.
Itching (especially palms/soles) is a reportable symptom — consider cholestasis of pregnancy.
Criteria and thresholds follow current guidelines and vary by institution — follow facility protocols.

6 review questions from the chapter. Try each one, then open the answer.

A pregnant person at 32 weeks reports painless bright red vaginal bleeding. What should the nurse suspect — and what action is contraindicated?
Show answer
Suspect placenta previa. A vaginal examination is contraindicated because it can trigger severe hemorrhage. Notify the provider, monitor maternal and fetal status, and prepare for ultrasound evaluation.
List four preeclampsia warning signs to teach a pregnant person.
Show answer
Any four of: persistent headache; visual changes (spots, blurring); epigastric or right-upper-quadrant pain; sudden severe swelling of face/hands; shortness of breath.
What does HELLP stand for, and why is it dangerous?
Show answer
Hemolysis, Elevated Liver enzymes, Low Platelets. A severe preeclampsia variant that can damage the liver and clotting system, sometimes with only vague symptoms like epigastric pain or nausea — life-threatening if missed.
Why does gestational diabetes usually resolve after birth, yet still matter long-term?
Show answer
GDM is caused by the insulin resistance of pregnancy hormones and usually disappears once the placenta is delivered. But it identifies the person as at higher risk for type 2 diabetes, so postpartum screening is recommended.
A pregnant person complains of severe itching on her palms and soles. Why should the nurse take this seriously?
Show answer
Intense itching, especially on palms and soles, is the hallmark of intrahepatic cholestasis of pregnancy, which is monitored closely because of fetal risks. Itching in pregnancy is reportable, not a minor annoyance.
What is the difference between gestational hypertension and preeclampsia?
Show answer
Gestational hypertension is new-onset high blood pressure without organ involvement; preeclampsia is hypertension plus evidence of organ involvement. Preeclampsia carries higher risk and more urgent management.
