The nurse is caring for a client in the active phase of the first stage of labor.

The client reports a new onset of severe abdominal pain.

What is the priority nursing action?

This obstetric scenario requires the application of maternal-fetal nursing knowledge regarding labor complications. Assessment priorities in the active phase must distinguish between normal labor progression and life-threatening emergencies like placental abruption or uterine rupture, requiring physical evaluation before intervention.

Choice A rationale

Pain medications might mask symptoms of a serious complication like placental abruption. Providing pharmacological relief without first assessing the source of sudden, severe abdominal pain violates the nursing process and delays necessary emergency interventions.

Choice B rationale

Assessing for vaginal bleeding and uterine tone is the priority to evaluate for placental abruption. Severe, constant abdominal pain during labor is an emergency signal. The normal assessment findings would show intermittent contraction-related discomfort.

Choice C rationale

Pulse oximetry measures systemic oxygen saturation but is not the most specific assessment for a fetal or uterine emergency. While vital signs are important, they do not pinpoint the cause of the acute abdominal pain.

Choice D rationale

Preparing for surgery is a premature action before a definitive assessment of the pain is performed. Although a cesarean may eventually be necessary, the nurse must first gather clinical evidence to justify such an intervention.

Priority assessment in obstetrics focuses on fetal well-being and identifying life-threatening complications. Clinical knowledge regarding fetal kick counts and placental perfusion must be applied to differentiate between normal physiological changes of pregnancy and signs of impending fetal compromise or demise.

Choice A rationale

Back pain is a common discomfort in pregnancy caused by shifts in the center of gravity and lumbar lordosis. While uncomfortable, it is not a priority finding compared to indicators of direct fetal distress or placental issues.

Choice B rationale

Decreased fetal movement is a critical sign of potential fetal hypoxia or distress. Fetal activity typically remains consistent, and a quiet baby requires immediate assessment via non-stress testing or ultrasound to ensure the fetus is still viable.

Choice C rationale

Varicosities in the lower extremities are common due to increased venous pressure from the enlarging uterus. While they require management like compression stockings, they do not pose an immediate threat to the life of the mother or fetus.

Choice D rationale

Increased fundal height can indicate polyhydramnios or macrosomia but is generally assessed over time. It does not carry the same immediate urgency as a sudden change in fetal movement, which suggests an acute oxygenation problem.
