Question

Difficulty: HardAnte/Intra/Postpartum and Newborn Care

A registered nurse is caring for a client at 38 weeks gestation in active labor. Fifteen minutes ago, the client received a continuous lumbar epidural infusion for pain management. The nurse assesses the client and notes that her blood pressure has decreased from 124/78 mmHg to 92/54 mmHg. Simultaneously, the external fetal monitor displays recurrent, gradual decreases in the fetal heart rate (FHR) that begin after the peak of the uterine contractions and return to the baseline only after the contractions have ended.

Which of the following actions should the nurse perform first?

  1. Assist the client into a lateral recumbent position and increase the rate of the primary intravenous fluid infusion.Answer
  2. B
    Prepare to administer a prescribed intravenous dose of ephedrine to correct the maternal hypotension.
  3. C
    Instruct the unlicensed assistive personnel (UAP) to monitor and report the maternal blood pressure every 3 minutes.
  4. D
    Document the vital signs and fetal heart rate tracing as a transient, expected physiological response to epidural analgesia.

Answer

Assist the client into a lateral recumbent position and increase the rate of the primary intravenous fluid infusion.
The correct response addresses the direct cause of the fetal distress. The client is experiencing epidural-induced hypotension, which reduces uteroplacental perfusion, leading to fetal hypoxia (manifested as late decelerations). The immediate nursing priority is to independently restore circulating maternal volume and blood flow to the uterus. Placing the client in a lateral recumbent position relieves aortocaval compression, and increasing the intravenous fluid rate expands intravascular volume. Both actions work synergistically to quickly improve maternal blood pressure and fetal oxygenation.

Step-by-Step Solution

1
Analyze the maternal vital signs.
The maternal blood pressure has significantly decreased following the epidural administration, indicating epidural-induced sympathetic blockade and vasodilation.
Epidural analgesia commonly blocks sympathetic vasomotor nerves, leading to peripheral blood pooling and decreased venous return to the heart.
2
Interpret the fetal heart rate (FHR) tracing.
The FHR shows recurrent, gradual decreases where the nadir occurs after the contraction peak, which are clinically defined as late decelerations.
Late decelerations signify uteroplacental insufficiency. In this scenario, they are secondary to the maternal hypotension physically reducing oxygenated blood flow to the placenta.
3
Prioritize nursing interventions based on ABCs and independent nursing scope.
The nurse must immediately implement independent mechanical actions to restore maternal circulating volume before utilizing dependent pharmacological orders or delegating tasks.
Repositioning the client laterally relieves aortocaval compression from the gravid uterus, and increasing IV fluids expands intravascular volume. Together, these actions represent the fastest, most effective first-line treatment to correct maternal hemodynamics and restore fetal oxygenation.
