A patient undergoing ovarian stimulation asks about the purpose of frequent ultrasounds. What should the nurse explain?

Correct Answer: B

Rationale: The correct answer is B because frequent ultrasounds are used to monitor the growth and development of ovarian follicles during ovarian stimulation. This is essential to ensure proper timing for ovulation induction or egg retrieval. Ultrasounds do not monitor embryo development after transfer (choice A), confirm natural ovulation (choice C), or visualize uterine contractions (choice D) in this context.

Correct Answer: B

Rationale: The correct answer is B. Estrogen plays a crucial role in thickening and vascularizing the endometrium to prepare for potential implantation of a fertilized egg. Estrogen does not prevent ovulation (choice A), as it actually promotes ovulation. It also does not directly stimulate egg release (choice C), as that is primarily controlled by luteinizing hormone. Estrogen indirectly influences progesterone production by triggering ovulation, but it does not directly increase progesterone production (choice D).

Correct Answer: B

Rationale: The correct answer is B because OHSS can indeed cause severe symptoms like abdominal pain and fluid accumulation in the abdomen or chest, which may require medical attention and monitoring. OHSS is a potential complication of ovarian stimulation, particularly in women undergoing fertility treatments. It is crucial for the nurse to explain the seriousness of OHSS symptoms and the importance of close monitoring to the patient. Choices A, C, and D are incorrect because OHSS is not a mild side effect, it can occur in women of all ages, and it can still happen with modern fertility medications. It is important to provide accurate information to the patient to ensure their understanding and safety during the treatment process.

Correct Answer: B

Rationale: The correct answer is B because luteal phase deficiency is caused by insufficient progesterone to maintain the uterine lining, which is crucial for implantation of a fertilized egg. This deficiency can lead to difficulty in sustaining a pregnancy. A is incorrect because estrogen levels are more related to follicular phase than luteal phase. C is incorrect because luteal phase deficiency can occur in women without PCOS. D is incorrect because immature eggs are more related to ovulation issues rather than luteal phase deficiency.

Correct Answer: B

Rationale: The correct answer is B because embryo freezing allows for future pregnancy attempts without additional egg retrieval. This is important as it saves time, cost, and reduces physical burden on the patient. Choice A is incorrect as success rates are similar for frozen and fresh embryos. Choice C is incorrect because hormonal support is still required during IVF with frozen embryos. Choice D is incorrect as genetically unmodified embryos can also be frozen.
