What is the role of pelvic ultrasound in infertility evaluation?

Correct Answer: B

Rationale: The correct answer is B, as pelvic ultrasound allows visualization of uterine and ovarian structures. This is essential in assessing conditions like fibroids, polyps, ovarian cysts, and structural abnormalities that may affect fertility. Ovarian reserve evaluation (A) involves separate tests like AMH levels. Hormone levels (C) are typically measured through blood tests. Genetic abnormalities in embryos (D) are usually identified through preimplantation genetic testing, not pelvic ultrasound.

Correct Answer: B

Rationale: The correct answer is B. Monitoring hormone levels during ovulation induction is essential to ensure that the hormones stay within safe and effective ranges for successful egg maturation. By closely monitoring hormone levels, healthcare providers can adjust medication dosages as needed to optimize the chances of successful ovulation. This helps to minimize the risk of overstimulation or understimulation of the ovaries, which can impact the quality of the eggs produced. A: Predicting embryo quality before fertilization is not the primary purpose of monitoring hormone levels during ovulation induction. C: Confirming pregnancy before the cycle ends is not the purpose of hormone level monitoring during ovulation induction. D: Determining if the uterine lining is ready for implantation is important, but this is typically assessed through other methods such as ultrasound rather than hormone level monitoring.

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.
