A patient asks about the benefits of Preimplantation Genetic Testing (PGT) during IVF. What should the nurse explain?

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: 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.

Correct Answer: B

Rationale: The correct answer is B: To suppress natural hormone production and control the cycle. GnRH agonists work by initially stimulating the release of certain hormones that eventually lead to the suppression of natural hormone production. This helps to control the menstrual cycle and prevent premature ovulation. Other choices are incorrect because A is typically achieved through other medications, C is more related to other fertility treatments like IVF, and D is not a primary function of GnRH agonists.
