A patient undergoing fertility treatments asks about the role of luteinizing hormone (LH). What should the nurse explain?

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: 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.

Correct Answer: B

Rationale: The correct answer is B: To identify genetic abnormalities in embryos before implantation. PGT is used to screen embryos for genetic disorders before implantation in IVF to prevent the transmission of genetic diseases to the offspring. By identifying abnormalities, only healthy embryos are selected for transfer, increasing the chances of a successful pregnancy. Other choices are incorrect as PGT does not directly impact the number of embryos available (A), uterine receptivity (C), or egg production (D) during IVF.
