- A. Amenorrhea.
- B. Breast tenderness.

A pregnant woman who is 20 weeks gestation asks about the risk of consuming caffeine during pregnancy. Which of the following responses is most appropriate?
- A. It is safe to consume up to 200 mg of caffeine per day during pregnancy.
- B. You should avoid caffeine completely during pregnancy.
- C. Moderate caffeine consumption is okay, but avoid drinking coffee in the afternoon.
- D. Caffeine has no impact on your pregnancy, so you can drink it as desired.
Correct Answer: A
Rationale: The correct answer is A because current guidelines suggest that consuming up to 200 mg of caffeine per day is considered safe during pregnancy. This amount is unlikely to harm the developing fetus. Excessive caffeine intake has been associated with an increased risk of miscarriage and low birth weight.
Option B is incorrect as complete avoidance of caffeine is not necessary, but rather moderation is key. Option C is partially correct in emphasizing moderation but the recommendation to avoid coffee in the afternoon is not supported by evidence. Option D is incorrect as caffeine does have an impact on pregnancy, and unrestricted consumption is not advisable.
A 35-week pregnant woman presents with ruptured membranes. What is the priority intervention?
- A. Check for cord prolapse
- B. Monitor for fetal distress
- C. Administer antibiotics
- D. Perform a vaginal exam to assess cervical dilation
Correct Answer: A
Rationale: The correct answer is A: Check for cord prolapse. This is the priority intervention because with ruptured membranes, there is a risk of umbilical cord prolapse, which can lead to fetal compromise. Checking for cord prolapse allows for quick identification and immediate intervention to prevent potential harm to the baby.
Choice B is incorrect as monitoring for fetal distress is important but not the immediate priority when cord prolapse is a concern. Choice C, administering antibiotics, may be necessary but does not address the immediate risk of cord prolapse. Choice D, performing a vaginal exam, can increase the risk of infection and should be avoided until cord prolapse is ruled out.
