The nurse is caring for a client who has been prescribed an IV infusion of oxytocin to induce labor.

The client is gravida 1 para 0. The fetus is in a vertex cephalic presentation and the patient's cervix is dilated 1cm.

Which is the priority action for the nurse before starting the oxytocin induction?

Identifying obstetric complications requires analyzing clinical presentation and risk factors. One must apply knowledge of pathophysiology regarding premature placental separation versus placental positioning or hypertensive disorders to interpret the most likely diagnosis based on symptoms like painful bleeding or hypertension.

Choice A rationale

Placental abruption involves the premature detachment of the placenta, typically presenting with painful vaginal bleeding and uterine tenderness. This is a medical emergency that compromises fetal oxygenation and can lead to maternal disseminated intravascular coagulation and severe hemorrhage.

Choice B rationale

Placenta previa occurs when the placenta covers the internal cervical os. Scientifically, this condition is classically characterized by painless, bright red vaginal bleeding in the third trimester, differing from the painful presentation usually associated with placental abruption or labor.

Choice C rationale

Preeclampsia is a multisystem hypertensive disorder defined by blood pressure ≥ 140/90 mmHg and proteinuria after 20 weeks. While it is a significant risk factor for placental abruption, it does not inherently cause vaginal bleeding unless abruption occurs.

Choice D rationale

Preterm labor involves cervical changes and regular uterine contractions before 37 weeks. While it may involve a bloody show, it does not typically present with the significant vaginal bleeding or acute pain associated with more severe placental complications..

Newborn thermoregulation is critical due to their high surface area to mass ratio. Nurses must apply knowledge of heat loss mechanisms, specifically evaporation, to explain how drying the infant prevents cold stress, metabolic acidosis, and respiratory distress in the neonate.

Choice A rationale

Evaporation is the primary source of heat loss immediately after birth due to amniotic fluid. Drying the infant with warm blankets removes moisture, significantly reducing heat loss and preventing the cascade of physiological complications associated with neonatal cold stress.

Choice B rationale

Newborns possess limited ability to shiver for heat production, relying instead on nonshivering thermogenesis through brown fat metabolism. Wrapping them helps retain heat, but the rationale regarding shivering is physiologically inaccurate for the neonatal population during the immediate recovery.

Choice C rationale

Acrocyanosis, or bluish discoloration of hands and feet, is a normal vasomotor finding in the first 24 to 48 hours of life. It results from peripheral perfusion adjustments rather than strictly external temperature and does not require thermal intervention.

Choice D rationale

Prevention is the standard of care rather than reactive warming. Waiting for a low temperature, typically below 36.5 degrees Celsius or 97.7 degrees Fahrenheit, puts the infant at risk for hypoglycemia and increased oxygen consumption during thermogenesis.
