Correct Answer: B

Rationale: The correct answer is B because implantation typically occurs between 6 to 10 days after conception, not 2 to 3 days. It is crucial for the nurse to intervene and provide accurate information to ensure the client receives correct education about conception. Choice A is correct as fertilization does occur in the outer third of the fallopian tube. Choice C is also accurate as sperm can remain viable in the woman's reproductive tract for 2 to 3 days. Choice D is correct as bleeding or spotting can indeed accompany implantation.

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: C

Rationale: Quickening, which is the first perception of fetal movements by the mother, typically occurs between the fourth and fifth months of pregnancy, around 18-20 weeks of gestation. Choice C is correct as it provides the client with accurate information about the expected timing of this significant milestone in her pregnancy. Choices A, B, and D are incorrect because quickening does not happen during the last trimester, by the end of the first trimester, or once the uterus begins to rise out of the pelvis. The correct timeframe for quickening is during the second trimester, specifically between the fourth and fifth months.

Correct Answer: B

Rationale: The basal body temperature should be taken every morning before arising as it provides the most accurate reading. This time ensures consistency and eliminates variations that may occur throughout the day due to activities or environmental factors. Choice A is incorrect because ovulation can vary among individuals, and checking temperature on specific days may not align with the actual ovulation day. Choice C is incorrect as there is no direct correlation between intercourse and basal body temperature. Choice D is incorrect because taking the temperature before going to bed does not provide a consistent baseline reading.

Correct Answer: B

Rationale: The described pattern suggests late decelerations, indicating uteroplacental insufficiency. Discontinuing the oxytocin infusion helps reduce uterine contractions, improving placental blood flow and fetal oxygenation. This intervention is essential to prevent fetal compromise and potential harm during labor. Choice A is incorrect because decreasing the rate of the maintenance IV solution does not directly address the cause of the late decelerations. Choice C is incorrect because increasing the rate of IV oxytocin can worsen uterine contractions, exacerbating the fetal distress. Choice D is incorrect because slowing the client's breathing rate is not indicated in the management of late decelerations during labor.
