Correct Answer: B

Rationale: Changing the client's position is the priority intervention for variable decelerations as it can relieve pressure on the umbilical cord, potentially resolving the deceleration and improving fetal oxygenation. Assessing cervical dilation, administering oxygen via facemask, and turning off the oxytocin infusion are important interventions but addressing the fetal distress caused by variable decelerations takes precedence.

Correct Answer: A

Rationale: The client's readiness to learn is the most critical factor influencing successful teaching of the gravid client. When a client is receptive and motivated to learn, they are more likely to engage with the information provided, leading to better understanding and retention.

Correct Answer: D

Rationale: Active herpes lesions at the time of delivery increase the risk of neonatal transmission. The most appropriate action in this scenario is to prepare the client for a cesarean section. A cesarean section is often recommended to reduce the risk of neonatal transmission of herpes simplex virus during delivery, especially when active lesions are present. This intervention helps minimize direct contact between the newborn and the infected genital tract secretions, thereby decreasing the risk of transmission.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to inform and assure the mother that this weight loss is normal. Newborns can lose up to 10% of their birth weight in the first few days after birth, which is attributed to fluid loss and adjustment to life outside the womb. This weight loss is typically regained within the first two weeks of life. It is crucial for the nurse to educate and provide reassurance to the mother about this common occurrence in newborns.
