Question

Difficulty: EasyAnte/Intra/Postpartum and Newborn Care

A client in the first stage of labor is connected to continuous external electronic fetal monitoring. The nurse observes that the fetal heart rate gradually decreases at the exact onset of each uterine contraction, reaches its lowest point precisely at the peak of the contraction, and returns to baseline just as the contraction ends. Which of the following is the most appropriate action for the nurse to take?

  1. Document the findings and continue routine monitoring.Answer
  2. B
    Reposition the client to the left lateral position and administer oxygen.
  3. C
    Notify the healthcare provider immediately for further evaluation.
  4. D
    Instruct the unlicensed assistive personnel to gather supplies for an emergency cesarean birth.

Answer

Document the findings and continue routine monitoring.
The clinical description outlines early decelerations, which occur when the fetal head is compressed against the maternal pelvis or soft tissues during a contraction. This triggers a vagal response, safely slowing the fetal heart rate. Because this is a normal, expected finding during labor that does not compromise fetal oxygenation, the only required nursing action is to document the rhythm and continue standard care.

Step-by-Step Solution

1
Analyze the relationship between the fetal heart rate and the uterine contractions.
The decrease in fetal heart rate perfectly mirrors the uterine contraction (starts with the contraction, peaks with the contraction, and ends with the contraction).
Identifying the timing of the deceleration in relation to the contraction is essential for classifying the type of deceleration.
2
Identify the type of deceleration.
The pattern describes an early deceleration.
Early decelerations are uniform and mirror the contraction precisely.
3
Determine the physiological cause and the necessary nursing intervention.
The cause is fetal head compression, which is benign and requires only documentation.
Since early decelerations do not represent fetal hypoxia or distress, aggressive interventions are contraindicated.
