A nurse is explaining the significance of luteal phase support in fertility treatments. What should the nurse emphasize?

Correct Answer: B

Rationale: The correct answer is B. Luteal phase support involves supplementing progesterone to maintain the uterine lining, crucial for implantation and early pregnancy support. Progesterone prepares the endometrium for implantation and helps sustain early pregnancy. Other choices are incorrect: A is incorrect as ovulation is triggered by the surge in luteinizing hormone, not luteal phase support. C is incorrect as egg quality is primarily influenced during ovarian stimulation, not luteal phase support. D is incorrect as estrogen is not the primary hormone involved in preventing implantation failure, it is progesterone.

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.

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.
