Zorluk: OrtaAnte/Intra/Postpartum and Newborn Care

A gravid client at 40 weeks of gestation is undergoing an induction of labor with intravenous oxytocin. The external fetal monitor displays a continuous pattern where the fetal heart rate gradually decreases, with the nadir occurring consistently after the peak of the uterine contractions. The heart rate recovers to the baseline only after the contractions have completely ended. Based on these findings, which intervention is most critical for the nurse to implement?

  1. Suspend the continuous oxytocin infusion, assist the client into a lateral position, and administer an isotonic fluid bolus.Cevap
  2. B
    Document the fetal monitor findings as a benign physiological response to head compression and continue routine observation.
  3. C
    Place the client in a flat, supine position and elevate the lower extremities to increase maternal venous return.
  4. D
    Perform an immediate sterile vaginal examination to assess for the presence of a prolapsed umbilical cord.

Cevap

The most critical intervention is to suspend the continuous oxytocin infusion, assist the client into a lateral position, and administer an isotonic fluid bolus.
The scenario describes late decelerations, which are characterized by a gradual decrease in the fetal heart rate that reaches its lowest point after the peak of the uterine contraction. This pattern indicates uteroplacental insufficiency and potential fetal hypoxia. The immediate priority is intrauterine resuscitation to improve placental blood flow and fetal oxygenation. This involves a sequence of actions often remembered by the acronym POISE or similar protocols: stopping the oxytocin (to reduce uterine activity), positioning the client laterally (to relieve aortocaval compression), increasing intravenous fluids (to optimize maternal cardiac output), and administering oxygen.

Adım Adım Çözüm

1
Analyze the fetal heart rate tracing described in the scenario.
The gradual decrease in fetal heart rate with the nadir occurring after the peak of the contraction identifies the pattern as late decelerations.
Accurate pattern recognition is necessary to determine the underlying physiological cause.
2
Determine the pathophysiological cause of late decelerations.
Late decelerations are caused by uteroplacental insufficiency, meaning the fetus is experiencing transient hypoxemia during contractions.
Understanding the cause dictates the appropriate clinical interventions to restore adequate oxygenation.
3
Select the appropriate nursing interventions for intrauterine resuscitation.
The nurse must improve placental blood flow and oxygenation by stopping the oxytocin (which causes the contractions), repositioning the client laterally (to relieve vena cava compression), and administering an IV fluid bolus (to increase maternal blood volume).
These combined actions directly address the uteroplacental insufficiency and prevent further fetal compromise.
