A couple is considering ICSI (Intracytoplasmic Sperm Injection) as part of IVF. What should the nurse explain?

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 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.

Correct Answer: B

Rationale: The correct answer is B: It collects mature eggs from the ovaries for fertilization in the lab. Rationale: 1. Egg retrieval in IVF involves retrieving mature eggs from the woman's ovaries to be fertilized with sperm in a laboratory setting. 2. These fertilized eggs (embryos) are then transferred back into the uterus for potential implantation. 3. This process is crucial for successful IVF as it allows for controlled fertilization outside the body. Summary of other choices: A: Incorrect. Egg retrieval is not for storing immature eggs but for obtaining mature eggs for immediate fertilization. C: Incorrect. Egg retrieval is not for monitoring ovarian reserve; this is typically done through other tests. D: Incorrect. Egg retrieval occurs before implantation to collect eggs for fertilization, not after implantation.

Correct Answer: B

Rationale: The correct answer is B: To promote the growth and maturation of ovarian follicles. FSH plays a crucial role in the menstrual cycle by stimulating the development of ovarian follicles in the ovary. As FSH levels rise, it triggers the growth of multiple follicles, one of which will eventually mature and release an egg during ovulation. Choice A is incorrect because it is actually luteinizing hormone (LH) that triggers the release of a mature egg. Choice C is incorrect as thickening of the uterine lining is primarily influenced by estrogen and progesterone. Choice D is incorrect because progesterone production is mainly regulated by luteinizing hormone (LH) and not FSH.
