A nurse is assisting with the care of a client who is in labor. Immediately after the delivery of a newborn, which of the following actions should the nurse take first?

Choice A rationale:

Increasing the rate of the maintenance IV infusion may be a rational action in some situations, but it is not the first priority when dealing with a fetal heart rate deceleration. The priority is to address the deceleration and potential fetal distress promptly.

Choice B rationale:

Administering oxygen using a nonrebreather mask might be beneficial for the client, but it is not the primary action to take when dealing with fetal heart rate deceleration. The priority is to address the deceleration and ensure fetal well-being.

Choice C rationale:

Elevating the client's legs is unlikely to have a significant impact on fetal heart rate deceleration. This action is more relevant in cases of maternal hypotension or when trying to improve venous return to the heart. It is not the first-line intervention for fetal heart rate decelerations.

Choice D rationale:

Placing the client in the lateral (side-lying) position is the correct action to take first. This position can help relieve pressure on the vena cava, improve blood flow, and increase oxygen supply to the fetus. By changing the client's position, the nurse can potentially resolve the fetal heart rate deceleration and improve fetal well-being.

Choice A rationale:
Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.
Choice B rationale:
Umbilical cord compression is a known cause of variable decelerations in the fetal heart rate. When the umbilical cord is compressed, it can temporarily disrupt blood flow and oxygen supply to the fetus, leading to decelerations. Variable decelerations often appear as abrupt, sharp drops in the fetal heart rate and are typically characterized by their unpredictable
nature.
Choice C rationale:
Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.
Choice D rationale:
Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which can lead to late decelerations in the fetal heart rate, not variable decelerations.
