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.

A provider has ordered several diagnostic procedures for a couple with suspected infertility. Which diagnostic procedure is useful for determining if ovulation has occurred?
- A. FSH level
- B. Progesterone level
- C. Estrogen level
- D. Vaginal ultrasound
Correct Answer: B
Rationale: The correct answer is B: Progesterone level. Progesterone is the hormone secreted after ovulation, indicating that ovulation has occurred. Monitoring progesterone levels can confirm ovulation. FSH (A) and estrogen (C) levels reflect the ovarian function but do not directly confirm ovulation. Vaginal ultrasound (D) can visualize the ovaries but does not definitively confirm ovulation.
What advice should the nurse give a patient with irregular periods trying to conceive?
- A. Track ovulation using basal body temperature and ovulation kits.
- B. Increase carbohydrate intake to regulate cycles.
- C. Avoid exercise to prevent further irregularity.
- D. Undergo hormone therapy immediately.
Correct Answer: A
Rationale: The correct answer is A because tracking ovulation using basal body temperature and ovulation kits helps identify the most fertile days for conception. This method allows the patient to time intercourse effectively. Increasing carbohydrate intake (B) does not address the root cause of irregular periods. Avoiding exercise (C) is not recommended as moderate exercise can actually help regulate menstrual cycles. Undergoing hormone therapy immediately (D) is an aggressive approach and should only be considered after other options have been explored.
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.
A male client has green color blindness, an X-linked recessive genetic disorder. His wife has no affected genes. Which of the following statements by the nurse is true regarding the couple's potential for having a child who is color blind?
- A. All male children will be color blind.
- B. All female children will be color blind.
- C. All male children will be carriers for color blindness.
- D. All female children will be carriers for color blindness.
Correct Answer: D
Rationale: Female children will be carriers, as they inherit the gene from their father.
