A patient asks about the effects of smoking on male fertility. What should the nurse include in the response?

Correct Answer: B

Rationale: The correct answer is B because smoking has been proven to negatively impact male fertility by reducing sperm count, motility, and morphology. Nicotine and other harmful chemicals in cigarettes can damage sperm DNA and affect reproductive health. Choice A is incorrect as smoking actually decreases testosterone levels. Choice C is incorrect as smoking does have a significant impact on male reproductive health. Choice D is incorrect because smoking alone can still affect male fertility without the need for alcohol use.

Correct Answer: B

Rationale: The correct answer is B: Progesterone injections support the uterine lining for implantation and pregnancy maintenance. Progesterone is essential for preparing the uterus for implantation and maintaining a pregnancy. After embryo transfer, progesterone helps thicken the uterine lining, making it more receptive to the embryo for successful implantation. Other choices are incorrect: A is incorrect because progesterone does not affect the number of eggs released in future cycles; C is incorrect because progesterone does not prevent ovarian cyst formation; D is incorrect because while progesterone can help alleviate some pregnancy symptoms, its primary role is in supporting the uterine lining for pregnancy.

Correct Answer: B

Rationale: The correct answer is B: To stimulate the release of an egg from the ovary. LH surge triggers ovulation, releasing the mature egg from the follicle. This is crucial for fertility. A is incorrect because progesterone maintains the uterine lining, not LH. C is incorrect as LH doesn't regulate progesterone during pregnancy, but plays a role in ovulation. D is incorrect as LH and FSH work together to regulate the menstrual cycle, not inhibit each other.

Correct Answer: A

Rationale: The correct answer is A because IUI (Intrauterine Insemination) bypasses the cervix and places sperm directly in the uterus, increasing the chances of sperm reaching the fallopian tubes to fertilize the egg. This method improves the sperm's proximity to the egg, optimizing the chances of conception. The other choices are incorrect because B (enhancing egg quality) is not achieved through IUI, C (eliminating ovulation tracking) is not true as tracking is still necessary for timing the procedure, and D (combining egg and sperm outside the body) describes in vitro fertilization (IVF), not IUI.

Correct Answer: B

Rationale: The correct answer is B: Embryo transfer typically occurs 3 to 5 days after fertilization. This timing aligns with the development of embryos to the blastocyst stage, which is crucial for successful implantation in the uterus. By waiting until this stage, the chances of a successful pregnancy are increased. Choice A is incorrect because embryos do not reach the blastocyst stage on the day of fertilization. Choice C is incorrect as embryo development stage is a key factor in determining the timing of transfer. Choice D is incorrect as waiting until pregnancy is confirmed would delay the transfer unnecessarily.
