A nurse is admitting a client who is at 38 weeks of gestation following a spontaneous rupture of membranes. The nurse performs a vaginal examination and palpates the umbilical cord. Which of the following actions should the nurse take?

Choice A rationale:

Decreasing the maintenance IV solution infusion rate is not the appropriate action for addressing late decelerations of the fetal heart rate. Late decelerations are a concerning sign during labor, indicating possible fetal distress. This can be caused by inadequate oxygenation of the fetus, and reducing IV fluids would not directly address this issue.

Choice B rationale:

Placing the client in a lateral (side-lying) position is the correct action when late decelerations are observed. This position helps to improve uteroplacental blood flow and can relieve pressure on the inferior vena cava, thus increasing oxygen supply to the fetus.

Choice C rationale:

Administering oxygen via face mask at 2 L/min is not the priority action in response to late decelerations. While oxygen may be beneficial in certain situations, it is not the initial intervention for addressing fetal heart rate decelerations.

Choice D rationale:

Administering misoprostol 25 mcg vaginally is not appropriate for addressing late decelerations. Misoprostol is a medication used for cervical ripening and induction of labor, but it does not directly address fetal heart rate changes.

Choice A rationale:

Requesting that the provider insert an intrauterine pressure catheter is not the immediate action the nurse should take when the umbilical cord is palpated during a vaginal examination. The priority is to relieve pressure on the cord and improve fetal oxygenation.

Choice B rationale:

Exerting continuous upward pressure on the presenting part is the correct action when the nurse palpates the umbilical cord during a vaginal examination. This manoeuvre is called "vaginal elevation,”. helps lift the presenting part off the umbilical cord, reducing the risk of cord compression and fetal distress until the provider can take further action.

Choice C rationale:

Initiating oxytocin via continuous IV infusion is not appropriate when the umbilical cord is palpated during a vaginal examination. Oxytocin can cause uterine contractions, potentially further compromising the cord and fetus.

Choice D rationale:

Placing the client in the left-lateral position is not the best immediate action for cord palpation. While the left-lateral position is useful for relieving pressure on the vena cava in cases of supine hypotensive syndrome, the priority here is to relieve cord compression, and upward pressure on the presenting part is more effective.
