Chapter 5: Pregnancy Complications: Nursing Care & Risks

Pregnancy Complications: Nursing Care & Risks educational overview explores the complex management of high-risk pregnancies, focusing on conditions that jeopardize the health of the mother or the fetus. It begins by outlining critical fetal diagnostic tests, including ultrasound imaging for gestational dating and anomaly detection, amniocentesis for genetic screening, and the biophysical profile to evaluate placental sufficiency through heart rate reactivity and amniotic fluid volume. The summary details significant bleeding disorders, differentiating between early pregnancy issues like spontaneous abortions, ectopic pregnancies (where the zygote implants outside the uterus), and hydatidiform moles, and late-term complications such as placenta previa and abruptio placentae. A major focus is placed on hypertensive disorders, specifically the progression of preeclampsia—marked by elevated blood pressure, proteinuria, and systemic edema—to the seizure activity of eclampsia, highlighting the vital role of magnesium sulfate in seizure prevention and the monitoring for potential toxicity. Blood incompatibilities, particularly Rh isoimmunization, are addressed with an emphasis on the preventative administration of RhoGAM to Rh-negative mothers. The chapter further examines how chronic medical conditions like diabetes mellitus and heart disease necessitate specialized care to prevent complications such as fetal macrosomia or maternal cardiac failure. Nutritional and genetic anemias, including iron deficiency and sickle cell disease, are analyzed for their impact on oxygen transport. Additionally, the summary covers various infectious threats summarized by the TORCH acronym, alongside Group B Streptococcus and the Zika virus, noting their teratogenic potential. Finally, the discussion evaluates the impact of environmental hazards, substance abuse, and physical trauma—including the escalation of domestic violence during pregnancy—while emphasizing the nurse's role in providing psychosocial support and facilitating the grieving process for families experiencing perinatal loss.
