A nurse is teaching about sperm freezing for fertility preservation. What should be included in the education?

Correct Answer: B

Rationale: The correct answer is B because frozen sperm can indeed be stored indefinitely with proper conditions such as constant low temperatures. This allows men to preserve their fertility for an extended period. Choice A is incorrect as sperm freezing is effective for men of all ages, not just those over 40. Choice C is incorrect because sperm quality may decline slightly after freezing and thawing. Choice D is incorrect as properly stored frozen sperm can maintain viability for many years, not just within one year.

Correct Answer: B

Rationale: The correct answer is B because ICSI involves injecting a single sperm directly into an egg to facilitate fertilization. This method is used when there are issues with sperm quality or quantity. It is not limited to couples with unexplained infertility (choice A), does not guarantee successful pregnancy (choice C), and does not eliminate the need for ovarian stimulation (choice D). Therefore, choice B is the most accurate explanation of what ICSI entails.

Correct Answer: B

Rationale: The correct answer is B: It helps identify genetic abnormalities in embryos before transfer. PGT is used during IVF to screen embryos for genetic conditions, allowing for the selection of healthy embryos for transfer, reducing the risk of passing genetic disorders to offspring. This is a crucial benefit of PGT as it helps in making informed decisions about embryo selection. Choices A, C, and D are incorrect because PGT focuses on genetic screening of embryos, not on improving uterine health, eliminating the need for fertility testing, or guaranteeing a healthy pregnancy.

Correct Answer: B

Rationale: The correct answer is B because LH triggers ovulation by causing the release of a mature egg from the ovary. LH surge occurs around mid-cycle, stimulating the mature follicle to rupture and release the egg. This is crucial for fertility and conception. A is incorrect because LH does not stimulate the growth of the uterine lining; that is primarily regulated by estrogen and progesterone. C is incorrect because LH actually promotes follicle development and maturation. D is incorrect because LH is important for ovulation and not just during pregnancy.

Correct Answer: B

Rationale: The correct answer is B: To maintain the uterine lining and support early pregnancy. After embryo transfer in IVF, progesterone support is crucial to ensure the uterine lining remains thick and supportive for the implantation and early development of the embryo. Progesterone helps create a hospitable environment in the uterus for the embryo to implant and grow. It also supports the continued development of the pregnancy until the placenta can take over hormone production. Choice A is incorrect because progesterone support after embryo transfer is not aimed at stimulating egg growth during the next cycle. Choice C is incorrect as progesterone support does not trigger ovulation during the current cycle; ovulation would have already been induced prior to embryo transfer. Choice D is incorrect as preventing hormonal imbalances during stimulation is not the primary function of progesterone support after embryo transfer.
