Correct Answer: A

Rationale: The maternal serum alpha-fetoprotein (MSAFP) test is performed around 15-18 weeks of gestation to screen for neural tube defects and other developmental abnormalities in the fetus, not to assess fetal lung maturity, markers of fetal well-being, or Rh incompatibility between the mother and fetus. Choice A is the correct answer as it accurately reflects the purpose of the MSAFP test. Choices B, C, and D are incorrect because they do not align with the primary goal of this screening test.

Correct Answer: D

Rationale: Turning the client onto her side is the appropriate nursing intervention in this scenario. This position can help improve blood pressure by enhancing venous return, which may aid in increasing perfusion to vital organs. It can also alleviate pressure on the inferior vena cava, promoting better circulation and supporting blood pressure stabilization during labor. Choices A, B, and C are incorrect. A cesarean birth is not indicated based on the information provided. Assisting the client to an upright position may worsen her blood pressure due to decreased venous return. Lastly, there is no indication for an immediate vaginal delivery solely based on the client's blood pressure reading.

Correct Answer: A

Rationale: The correct answer is to apply an ice pack to the affected area. Ice packs help reduce swelling, inflammation, and provide pain relief post-episiotomy. Applying heat, as in a hot pack or warm sitz bath, can increase swelling and discomfort. Providing antiseptic solution in a squeeze bottle is not the first-line intervention for managing episiotomy pain, as the priority is pain relief and comfort.

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: During the active phase of the first stage of labor, contractions lasting longer than 90 seconds can indicate uterine hyperstimulation, leading to decreased placental perfusion and fetal oxygenation. This finding should be reported to the provider for further evaluation and management. Choices B, C, and D are not the priority findings in this scenario. Contractions occurring every 3 to 5 minutes are within the normal range for the active phase of labor. Strong contractions and feeling contractions in the lower back are common experiences during labor and not necessarily concerning unless associated with other complications.
