Question

Difficulty: MediumAnte/Intra/Postpartum and Newborn Care

A multiparous client at 41 weeks gestation is receiving a continuous intravenous oxytocin infusion for labor induction. External monitoring reveals a fetal heart rate baseline of 135 beats per minute with minimal variability. During the past 15 minutes, the nurse observes recurrent, uniform drops in the fetal heart rate that begin after the acme of each contraction and do not recover to baseline until the contraction has entirely finished. What is the priority nursing action at this time?

  1. A
    Document the tracing as an expected physiological response to fetal head compression.
  2. B
    Direct the unlicensed assistive personnel to assist the client into a left lateral position.
  3. Stop the continuous intravenous oxytocin infusion immediately.Answer
  4. D
    Contact the primary healthcare provider to report the findings before taking other actions.

Answer

Stop the continuous intravenous oxytocin infusion immediately.
The scenario describes late decelerations, which occur when fetal heart rate drops begin after the peak of a contraction and recover after the contraction ends. This indicates uteroplacental insufficiency, a potentially life-threatening condition for the fetus. The immediate priority is intrauterine resuscitation. Because oxytocin strongly stimulates uterine contractions and restricts placental blood flow, stopping the infusion is the most direct and crucial first step to improve fetal oxygenation.

Step-by-Step Solution

1
Analyze the fetal heart rate tracing described in the clinical scenario.
The fetal heart rate drops initiate after the peak (acme) of the contraction and do not recover until after the contraction is over.
Identifying the timing of decelerations relative to the uterine contraction cycle is essential to determine the physiological cause.
2
Correlate the observed pattern with its clinical significance.
The pattern indicates late decelerations, which signify uteroplacental insufficiency and potential fetal hypoxemia.
Late decelerations are non-reassuring indicators that placental perfusion is inadequate during contractions.
3
Determine the highest priority nursing intervention for this acute complication.
The first step in intrauterine resuscitation is to stop the oxytocin infusion.
Oxytocin stimulates uterine contractions, which compress maternal blood vessels and decrease blood flow to the fetus. Discontinuing the infusion directly mitigates the underlying cause of the compromised blood flow.
