Correct Answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

Correct Answer: A

Rationale: The priority nursing intervention in this situation is to palpate the client's uterine fundus. A boggy uterus that is not well contracted may indicate uterine atony, which can lead to postpartum hemorrhage. Palpating the fundus and massaging it if it is boggy helps to promote contractions and reduce bleeding, making it the most critical intervention to address the potential underlying issue. Assisting the client to a bedpan to urinate, preparing to administer oxytocic medication, or increasing the client's fluid intake are not the immediate priorities in this scenario compared to assessing and addressing the uterine fundus status.

Correct Answer: D

Rationale: Variable decelerations can indicate umbilical cord compression, which is a concern that may arise due to the umbilical cord being compressed during labor. This compression can lead to reduced blood flow and oxygen delivery to the fetus, necessitating close monitoring and potentially interventions to alleviate the pressure on the cord. Early decelerations are typically benign and mirror the contractions, indicating fetal head compression. Accelerations are reassuring patterns that show a healthy response to fetal movement. Late decelerations are concerning as they suggest uteroplacental insufficiency, indicating potential oxygen deprivation to the fetus.

Correct Answer: C

Rationale: An elevated temperature in a woman with ruptured membranes may indicate infection. Assessing the odor of the amniotic fluid can help determine if chorioamnionitis (an infection of the amniotic fluid) is present. This assessment is crucial to guide further interventions and management of the client's condition. Options A, B, and D are incorrect. Rechecking the client's temperature in 4 hours does not address the immediate concern of potential infection. Administering glucocorticoids intramuscularly is not indicated based solely on an elevated temperature. Preparing the client for an emergency cesarean section is premature and not supported by the information provided.

Correct Answer: B

Rationale: An apical heart rate of 130/min is within the expected range for a newborn. It is not necessary to seek verification from another nurse, call the provider for further assessment, or prepare for NICU transport based on this heart rate. Documenting the heart rate as an expected finding is the appropriate action in this situation as it falls within the normal range for a newborn's heart rate.
