A nurse is educating a male patient about improving sperm quality. What should the nurse suggest?

Correct Answer: B

Rationale: The correct answer is B: Maintain a healthy lifestyle, including balanced nutrition and avoiding smoking. This is because a healthy lifestyle promotes overall well-being and can positively impact sperm quality. Balanced nutrition provides essential nutrients for sperm production while avoiding smoking reduces oxidative stress that can harm sperm. Choice A is incorrect because increased exposure to saunas and hot tubs can actually raise scrotal temperature, potentially harming sperm quality. Choice C is incorrect as high-fat diets can lead to obesity and negatively impact sperm quality. Choice D is incorrect as exercise is beneficial for overall health, including sperm motility.

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

Correct Answer: C

Rationale: The correct answer is C: Each time you get pregnant, there will be a 25% chance that your child will inherit the gene from each parent and will have sickle cell disease. This is because sickle cell disease follows an autosomal-recessive inheritance pattern, meaning both parents must pass on the sickle cell gene for a child to have the disease. With each pregnancy, there is a 25% chance that the child will inherit one sickle cell gene from each parent, resulting in the disease. Choices A and D are incorrect because they do not accurately reflect the inheritance pattern of sickle cell disease. Choice B is incorrect because it suggests a 50/50 chance, which is not the case with autosomal-recessive inheritance.
