During fertility counseling, a patient asks about the impact of smoking on reproductive health. What should the nurse explain?

Correct Answer: B

Rationale: The correct answer is B. Smoking reduces fertility by impairing egg quality and sperm motility. Nicotine and other harmful chemicals in cigarettes can damage reproductive organs and decrease the chances of conception. Smoking has been linked to decreased ovarian reserve in women and decreased sperm quality in men. Choice A is incorrect because smoking does have a significant negative effect on fertility. Choice C is incorrect as smoking does not enhance the effectiveness of fertility medications; in fact, it can reduce their effectiveness. Choice D is incorrect because smoking affects both male and female fertility, not just male fertility.

Correct Answer: B

Rationale: The correct answer is B because fertility significantly declines after age 35 due to a decrease in the quantity and quality of eggs. As women age, the risk of chromosomal abnormalities in eggs increases, impacting fertility. Other choices are incorrect because fertility does not remain constant until menopause (A), age affects fertility regardless of other health issues (C), and fertility starts declining well before the age of 50 (D).

Correct Answer: B

Rationale: The correct answer is B because exposure to environmental toxins can indeed harm egg and sperm quality, leading to reduced fertility. Toxins can disrupt hormone balance, affect reproductive organs, and damage genetic material in eggs and sperm. This can result in difficulty conceiving or increased risk of miscarriage. Choices A, C, and D are incorrect. A is inaccurate as environmental toxins can impact fertility outcomes. C is incorrect as toxins can affect fertility at any age. D is misleading as avoiding toxins does not guarantee immediate conception, as fertility is influenced by various factors.

Correct Answer: D

Rationale: The correct answer is D because the interval of greatest fertility is indeed on the day of the LH surge and the following two days. This is when ovulation is most likely to occur, and intercourse during this time maximizes the chances of conception. Choice A is incorrect because ovulation predictor kits are typically available over the counter, no prescription is required. Choice B is incorrect because the kit measures urine LH levels, not serum. Choice C is incorrect as the LH surge usually precedes ovulation by around 24-36 hours, not 12 hours.

Correct Answer: B

Rationale: The correct answer is B: To support the uterine lining and enhance implantation success. Progesterone supplementation is crucial after embryo transfer in IVF because it helps prepare the uterine lining for implantation and provides hormonal support to maintain a pregnancy. Progesterone is essential for the embryo to implant and for the early stages of pregnancy to progress. Therefore, the purpose of progesterone supplementation is to enhance the chances of successful implantation and support early pregnancy development. Choices A, C, and D are incorrect: A: To induce ovulation for the next cycle - Progesterone supplementation is not used to induce ovulation after embryo transfer in IVF. Ovulation should have already occurred before the embryo transfer. C: To suppress natural hormone levels for better control - Progesterone supplementation is not used to suppress hormone levels but rather to support hormonal balance during the implantation phase. D: To eliminate the risk of multiple pregnancies - Progesterone
