A nurse is teaching a group about the benefits of folic acid supplementation before conception. What should the nurse emphasize?

Correct Answer: A

Rationale: The correct answer is A: Folic acid helps prevent neural tube defects in the developing fetus. The rationale is that folic acid is essential for the development of the neural tube in early pregnancy, which is crucial for the baby's brain and spinal cord formation. By emphasizing this benefit, the nurse educates about the importance of folic acid before conception to reduce the risk of neural tube defects. Choices B, C, and D are incorrect because folic acid does not improve chances of multiple pregnancies, is needed before conception and throughout pregnancy (not just in the third trimester), and is a supplement that complements prenatal vitamins rather than replacing them.

Correct Answer: B

Rationale: The correct answer is B because younger age is generally associated with higher success rates in fertility treatments due to factors like better egg quality and ovarian reserve. Older women may have lower success rates due to decreased egg quality and quantity. Choice A is incorrect as success rates do vary with age. Choice C is incorrect because male age can impact fertility treatment outcomes. Choice D is incorrect as age can impact fertility treatment outcomes for women younger than 50 as well.

Correct Answer: B

Rationale: The correct answer is B because lifestyle modifications such as reducing stress, maintaining a healthy weight, avoiding harmful substances, and exercising can improve male fertility by optimizing overall reproductive health. Stress reduction can positively impact hormone levels and sperm production. Choices A, C, and D are incorrect because lifestyle modifications do not directly guarantee successful fertilization, eliminate the need for medical treatments, or directly improve sperm motility and morphology.

Correct Answer: B

Rationale: The correct answer is B because a BMI within the normal range is associated with improved hormonal balance and ovulation, which are crucial factors for fertility. This is supported by research showing that both underweight and overweight BMI can negatively impact fertility. Choice A is incorrect as BMI does impact fertility outcomes. Choice C is incorrect as BMI plays a role before conception as well. Choice D is incorrect as a low BMI can actually decrease fertility rates due to hormonal imbalances.

Correct Answer: B

Rationale: The correct answer is B: AMH levels indicate ovarian reserve and egg quantity. This is because Anti-Müllerian Hormone (AMH) is primarily secreted by the ovaries and its levels in the blood reflect the number of remaining follicles in the ovaries, which correlates with ovarian reserve and egg quantity. This information is vital for assessing a woman's fertility potential, especially in the context of fertility treatments such as in vitro fertilization (IVF). Choice A is incorrect as AMH testing does not predict the exact time of ovulation, it assesses ovarian reserve. Choice C is incorrect as AMH testing is not used to confirm pregnancy success after IVF, but rather to determine the likelihood of successful response to ovarian stimulation. Choice D is incorrect as AMH does not determine sperm quality in male partners, as it is a hormone produced by the ovaries and is not related to male reproductive function.
