Nursing Management in High-Risk Pregnancy

Differentiate normal physiologic adaptations of pregnancy from pathologic findings that require further assessment or intervention.
Recognize early warning signs of maternal or fetal compromise and identify when immediate nursing action or escalation of care is indicated.
Compare and contrast common causes of bleeding in pregnancy and determine appropriate assessment priorities and safety precautions.
Describe assessment findings and nursing management for hypertensive disorders of pregnancy, including preeclampsia, severe features, and HELLP syndrome.
Prioritize nursing interventions using clinical judgment to support maternal–fetal stability across high-risk pregnancy conditions such as amniotic imbalances, premature rupture of membranes, and multiple gestation.

Sudden gush of fluid (COAT): Often indicative of premature rupture of membranes.
Vaginal Bleeding: Could signify miscarriage, placenta previa, or placental abruption.
Unrelenting headache, N/V (nausea/vomiting): May indicate preeclampsia or other complications.
Sudden onset of edema: Particularly in the face, hands, feet, and legs.
Epigastric pain: Could be a sign of liver distress or preeclampsia.
Pain, burning, discomfort during urination: May indicate urinary tract infection.
Signs of preterm contractions: Require immediate assessment.

Causes Include:
- Spontaneous Abortion (miscarriage): Often due to chromosomal abnormalities.
- Ectopic Pregnancy: Fertilized egg implants outside the uterus.
- Gestational Trophoblastic Disease: Such as hydatidiform mole.
- Cervical Insufficiency: Inability of the cervix to retain a pregnancy.

Placenta Previa: Placenta lies over the cervix.
Placental Abruption: Early separation of the placenta from the uterine wall.

Clotting Factors Affected:
- Factor VII, VIII, X, and fibrinogen.
Mediators: Protein X, plasmin, and platelets can contribute to increased clot formation or complications during pregnancy.

Definitions:
- Abortion: Loss prior to 20 weeks of gestation.
- Fetal Demise: Loss after 20 weeks of gestation.
Pathophysiology: Often remains unknown; can be due to genetic or structural reasons, especially during the first trimester.
Nursing Assessment:
- Assess vaginal bleeding, pain, and cramping.
- Monitor vital signs and provide support.
- Comfort and educate patients empathetically.

Chromosomal abnormalities, maternal illness, advanced maternal age, premature cervical dilation, chronic maternal infections, trauma, substance abuse, and antiphospholipid syndrome.
Expected Findings: Pain, rupture of membranes, fever, and hypotension/tachycardia related to hemorrhage.

Definition: Implantation of the ovum outside the uterus, most commonly in the fallopian tube.
Medical Emergency: Can lead to rupture and internal bleeding if untreated.
Symptoms: Present around 6-8 weeks after last menstrual period; involves bleeding and pain.
Nursing Role: Monitor hormone levels, provide emotional support, prepare for treatment, and teach about the condition.

Definition: A premalignant condition resulting from improper fertilization; can lead to gestational trophoblastic neoplasia.
Types:
- Complete Mole: Fertilized egg lacks maternal chromosomes, no fetal development.
- Partial Mole: Fertilization by two sperm leads to abnormal fetus.
Treatment: Immediate evacuation of uterine contents
Nursing Implications: Monitor long term with serial hCG and progesterone levels.

Definition: Painless cervical dilation leading to potentially second-trimester pregnancy loss.
Treatment:
- Medication: Progesterone prescribed starting at 16 weeks.
- Surgical Management: Cervical cerclage placed between 13-24 weeks.

Definition: Placenta covers the cervix, can lead to bleeding during later pregnancy stages.
Types: Complete, partial, marginal.
Symptoms: Painless vaginal bleeding in the second half of pregnancy; often found during routine ultrasound.
Nursing Role: Monitor for bleeding, conduct fetal assessments, educate about pelvic rest, and plan for cesarean delivery.

Definition: Abrupt separation from uterine wall; potentially lethal.
Risk Factors: History of previous abruption, maternal age >35, hypertension, substance use.
Signs and Symptoms: Vaginal bleeding, sharp pain, uterine tenderness, decreased fetal movement.
Differentiation with Placenta Previa:
- Extrinsic Factors: Dark bleeding, firm uterine tone in abruption; bright red bleeding in previa is often painless.

Chronic Hypertension: Requires medical treatment before 20 weeks; low-dose aspirin may be indicated.
Gestational Hypertension: Elevated BPs without evidence of preeclampsia; requires monitoring.
Preeclampsia: Defined by blood pressure readings of ">140/90 mm Hg" and proteinuria; monitoring of multiple vital signs is essential.

Pre-Eclampsia with Severe Features: Higher severity includes persistent headaches, visual disturbances, elevated liver enzymes, and decreased placental perfusion.
Laboratory Values: Platelets <100,000, elevated liver enzymes, renal impairment, and proteinuria are key markers.

To prevent seizures in severe cases; safety monitoring essential, particularly for respiratory function.
Signs of Toxicity: Respiratory depression, altered level of consciousness, diminished reflexes.

Normal Amount: Between 500ml to 2000ml.
Oligohydraminos: <500ml; risks of PROM/cord accidents.
Polyhydramnios: >2000ml; close monitoring, risks of engagement issues of the fetus.

Occurs before labor onset in 8-10% of pregnancies; management varies based on gestational age and signs of infection.

Management: Frequent ultrasounds, labor monitoring, potential surgical intervention. Nutritional assessments and education about increased risks are critical.

Supportive care and monitoring both antepartally and during labor to manage potential complications.
