Which of the following assessments is the nurse’s highest priority for a client in labor who has an epidural in place and is on continuous internal monitoring with a fetal scalp electrode and intrauterine pressure catheter, noting a strong contraction on the monitor and the client reporting nausea accompanied by an urgent need to have a bowel movement?

Choice A reason: Obtaining the client’s temperature, heart rate, and blood pressure assesses maternal status but is not the highest priority. Nausea and an urgent need for a bowel movement suggest advanced labor or fetal head compression. Fetal heart rate (FHR) monitoring is critical, as strong contractions may reduce placental perfusion, risking fetal hypoxia, which takes precedence over maternal vital signs to ensure immediate fetal safety. Choice B reason: Examining vaginal discharge for meconium indicates potential fetal stress but is not the highest priority. Nausea and bowel urgency suggest rapid labor progression or fetal head compression, impacting FHR. Assessing FHR first ensures fetal oxygenation status, as meconium is a secondary finding that does not immediately guide interventions for acute distress during strong contractions. Choice C reason: Determining the fetal heart rate in relationship to contractions is the highest priority, as nausea and bowel urgency indicate possible second-stage labor or fetal head compression, causing FHR decelerations. Strong contractions may reduce placental blood flow, risking hypoxia. Continuous monitoring via scalp electrode detects late or variable decelerations, guiding urgent interventions to ensure fetal safety. Choice D reason: Performing a sterile vaginal examination assesses labor progress but is not the highest priority. Nausea and bowel urgency suggest advanced labor, but FHR assessment takes precedence to rule out fetal distress. Vaginal exams risk infection or membrane rupture and do not directly address fetal oxygenation, critical during strong contractions that may compromise placental perfusion.
