During a routine intrapartum assessment of a client at 40 weeks of gestation, the nurse analyzes the continuous electronic fetal monitor tracing. The baseline fetal heart rate is 135 beats/min with moderate variability. The nurse notes that the fetal heart rate gradually decreases to 125 beats/min simultaneously with the onset of each uterine contraction, and returns to baseline exactly as the contraction ends. Which of the following is the most appropriate action by the nurse?
- Document the findings and continue to monitor the labor progression.Cevap
- BAssist the client into a left lateral position and administer an intravenous fluid bolus.
- CAdminister oxygen at 8 to 10 L/min via a nonrebreather face mask.
- DPrepare the equipment for an immediate prophylactic amnioinfusion.
Cevap
The nurse should document the findings and continue to monitor the labor progression, as the described pattern indicates benign early decelerations.
The fetal monitor tracing describes an early deceleration. Early decelerations are visually characterized by a gradual, symmetrical decrease in the fetal heart rate that perfectly mirrors the uterine contraction. The onset, nadir, and recovery of the deceleration align exactly with the onset, peak, and end of the contraction. This pattern is a normal physiological response caused by fetal head compression as the fetus descends into the birth canal, leading to a transient vagal response. Because this finding is entirely benign and does not indicate fetal hypoxia, the only appropriate nursing action is to document the reassuring finding and continue routine monitoring.

Anahtar Kavram
Early decelerations are a normal, benign finding caused by fetal head compression during contractions and require no intervention other than documentation.
