Maternal & Newborn Study Notes

Preeclampsia is a multisystem hypertensive disorder of pregnancy that occurs after 20 weeks of gestation. It is characterized by vasospasm and reduced perfusion to vital organs, including the placenta. If left untreated, it can progress to eclampsia, which involves maternal seizures and potential fetal death.

Study topic

Bleeding during the late second or third trimester is a medical emergency often caused by placenta previa or abruptio placentae. Placenta previa occurs when the placenta implants near or over the cervix, while abruption is the detachment of a normally implanted placenta. Rapid assessment and intervention are required to prevent maternal and fetal morbidity.

Study topic

The postpartum period, or puerperium, is the 6-week interval between birth and the return of reproductive organs to their non-pregnant state. Nursing care focuses on monitoring for hemorrhage, promoting uterine involution, and supporting the transition to parenthood. Assessment of the fundus and lochia is critical in the immediate hours following delivery.

Study topic

The neonatal period encompasses the first 28 days of life, during which the infant must undergo significant physiological adaptations. Key transitions include the initiation of respiration and the change from fetal to neonatal circulation. Nursing care emphasizes safety, thermoregulation, and early identification of complications.

Study topic

Labor is the process by which the fetus, placenta, and membranes are expelled from the uterus. It is divided into four distinct stages, each requiring specific nursing assessments and interventions. The nurse’s primary role is to ensure the safety of the mother and fetus while providing physical and emotional support.

Study topic

Gestational diabetes occurs when the body cannot produce enough insulin to overcome the insulin resistance caused by placental hormones. This condition usually develops in the second half of pregnancy and often resolves after delivery. Management is crucial to prevent fetal macrosomia and neonatal metabolic complications.
