A couple asks about the role of hormone testing in infertility evaluation. What should the nurse explain?
- A. Hormone testing is only necessary after conception.
- B. It identifies hormonal imbalances affecting ovulation and fertility.
- C. Hormone testing predicts the gender of future embryos.
- D. It measures physical factors like uterine health.
Correct Answer: B
Rationale: The correct answer is B because hormone testing is essential in identifying hormonal imbalances that can affect ovulation and fertility. By measuring hormone levels such as estrogen, progesterone, and follicle-stimulating hormone, healthcare providers can pinpoint issues that may be inhibiting conception. Hormone testing helps determine the timing of ovulation and the overall health of the reproductive system.
Choice A is incorrect because hormone testing is not solely for post-conception purposes; it is crucial in diagnosing infertility issues. Choice C is inaccurate as hormone testing does not predict the gender of embryos but rather focuses on hormonal balance. Choice D is also incorrect as hormone testing primarily assesses hormone levels, not physical factors like uterine health.

A client is in the third stage of labor. Which finding would alert the nurse that the placenta is separating?
- A. uterus becomes globular
- B. fetal head at vaginal opening
- C. umbilical cord shortens
- D. mucous plug is expelled
Correct Answer: A
Rationale: The uterus becoming globular and upward rising is a sign of placental separation. This change in shape indicates that the placenta is detaching from the uterine wall. The other options are not indicative of placental separation.
A patient undergoing IVF asks about blastocyst transfer. What is the nurse's best explanation?
- A. Blastocyst transfer occurs on the day of egg retrieval.
- B. It involves transferring embryos that have developed for 5 to 6 days.
- C. Blastocyst transfer guarantees pregnancy success.
- D. It is performed only when natural conception has failed.
Correct Answer: B
Rationale: The correct answer is B because blastocyst transfer typically occurs on day 5 or 6 after fertilization when the embryo has reached a more advanced stage of development. This increases the likelihood of successful implantation in the uterus. Choice A is incorrect because it does not align with the typical timeline of blastocyst transfer. Choice C is incorrect as pregnancy success is not guaranteed with blastocyst transfer, though it may improve the chances. Choice D is incorrect as blastocyst transfer is a standard procedure in IVF and not limited to cases where natural conception has failed.
A nurse is educating a patient about ovulation tracking. What method should the nurse recommend?
- A. Using ovulation predictor kits to detect the LH surge.
- B. Tracking cervical mucus changes only after ovulation.
- C. Measuring basal body temperature in the evening.
- D. Testing progesterone levels daily.
Correct Answer: A
Rationale: The correct answer is A: Using ovulation predictor kits to detect the LH surge. This method is recommended because it directly detects the hormone surge that triggers ovulation, providing a reliable indication of the most fertile period for conception. Tracking cervical mucus changes only after ovulation (B) may not accurately predict the fertile window. Measuring basal body temperature in the evening (C) is less accurate than measuring it in the morning. Testing progesterone levels daily (D) is not a practical or necessary method for ovulation tracking.
The nurse is counseling a couple about ovulation predictor kits. What is the most important advice?
- A. They require a prescription.
- B. They detect the LH surge, signaling ovulation within the next 24 to 36 hours.
- C. They are most effective when used randomly during the cycle.
- D. They confirm pregnancy rather than ovulation.
Correct Answer: B
Rationale: The correct answer is B because ovulation predictor kits detect the LH surge, which occurs approximately 24 to 36 hours before ovulation. This information is crucial for timing intercourse to maximize the chances of conception. Choice A is incorrect because ovulation predictor kits are typically available over the counter and do not require a prescription. Choice C is incorrect because these kits should be used strategically around the expected time of ovulation for accurate results. Choice D is incorrect because ovulation predictor kits do not confirm pregnancy; they only indicate the LH surge and impending ovulation.
What is the significance of progesterone in confirming ovulation?
- A. Low progesterone levels indicate successful ovulation.
- B. Elevated progesterone levels confirm that ovulation has occurred.
- C. Progesterone levels do not fluctuate during the cycle.
- D. Progesterone testing is only relevant during pregnancy.
Correct Answer: B
Rationale: The correct answer is B: Elevated progesterone levels confirm that ovulation has occurred. Progesterone is produced by the corpus luteum after ovulation, supporting the uterine lining for potential implantation. Elevated progesterone levels indicate a functional corpus luteum, which only occurs after ovulation. Low progesterone levels do not indicate successful ovulation as they may suggest anovulation or inadequate luteal phase support. Progesterone levels fluctuate during the menstrual cycle, peaking post-ovulation. Progesterone testing is not only relevant during pregnancy but also in assessing ovulation and menstrual cycle health.
