A man has been instructed to make an appointment with the laboratory for sperm analysis. Which instruction should the nurse provide?

Correct Answer: B

Rationale: The correct answer is B because delivering the sample to the laboratory within 1 hour of collection ensures the sample is fresh and provides accurate results. Keeping the sample in a cooler (choice A) is unnecessary and may not be feasible. Collecting the sample during frequent sexual activity (choice C) can skew results. Withdrawal method (choice D) may not provide an adequate sample for analysis. Timing and freshness are crucial for accurate results.

Correct Answer: C

Rationale: Rationale: C is correct because hysterosalpingogram involves injecting a radiopaque dye into the uterine cavity to visualize the uterus and fallopian tubes. This helps identify any blockages or abnormalities. A is incorrect as the procedure is usually done without general anesthesia. B is incorrect as the procedure is typically scheduled in the early follicular phase. D is incorrect as Tylenol may not be sufficient for managing post-procedure cramping.

Correct Answer: B

Rationale: The correct answer is B because moderate exercise and a balanced diet are essential for overall health, including fertility. Exercise can help regulate hormones and improve circulation to reproductive organs. A balanced diet provides necessary nutrients for optimal reproductive function. Choice A is incorrect as complete avoidance of caffeine and alcohol is not necessary for fertility. Choice C is incorrect as excessive protein intake can negatively impact fertility. Choice D is incorrect as herbal supplements can have unknown effects on fertility and should be avoided without consulting a healthcare provider.

Correct Answer: B

Rationale: The correct answer is B: To maintain the uterine lining for implantation and pregnancy. Progesterone is crucial in early pregnancy as it helps in thickening and maintaining the uterine lining to support implantation of the fertilized egg and sustain the pregnancy. It also plays a role in suppressing the immune response to prevent rejection of the embryo. A: To stimulate fetal development - Incorrect. Progesterone primarily focuses on preparing the uterus for pregnancy rather than directly stimulating fetal development. C: To trigger ovulation and release of the egg - Incorrect. Progesterone is involved in the second half of the menstrual cycle after ovulation has occurred and is not responsible for triggering ovulation. D: To increase the production of amniotic fluid - Incorrect. Progesterone does not directly impact the production of amniotic fluid, which is mainly regulated by the fetal kidneys and placenta.

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.
