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: A

Rationale: Painless red vaginal bleeding is a hallmark sign of placenta previa. In this condition, the placenta partially or completely covers the cervical opening, leading to painless, bright red bleeding due to the separation of the placenta from the uterine wall. Other types of bleeding, such as those associated with abdominal pain or mucus passage, are more indicative of conditions like placental abruption rather than placenta previa. Therefore, choices B, C, and D are incorrect as they describe findings more consistent with placental abruption rather than placenta previa.

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: 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: Consume foods fortified with folic acid. Folic acid plays a crucial role in preventing neural tube defects. It is advised to consume foods fortified with folic acid or take a supplement containing at least 400 micrograms of folic acid daily. This nutrient is essential for the developing fetus and can significantly reduce the risk of neural tube defects when taken before and during early pregnancy. Choices A, B, and D are incorrect. While limiting alcohol consumption is important during pregnancy, it is not directly related to reducing the risk of neural tube defects. Increasing intake of iron-rich foods is essential for preventing anemia but is not specifically linked to neural tube defects. Avoiding foods containing aspartame is generally recommended, but it is not directly related to reducing the risk of neural tube defects.
