A nurse is instructing a woman on the use of ovulation predictor kits. What should the nurse emphasize?
- A. A prescription is required.
- B. The kit will determine a serum LH level.
- C. The LH surge usually occurs 12 hours prior to ovulation.
- D. Your interval of greatest fertility is on the day of the LH surge and the following two days.
Correct Answer: D
Rationale: The correct answer is D because the interval of greatest fertility is indeed on the day of the LH surge and the following two days. This is when ovulation is most likely to occur, and intercourse during this time maximizes the chances of conception. Choice A is incorrect because ovulation predictor kits are typically available over the counter, no prescription is required. Choice B is incorrect because the kit measures urine LH levels, not serum. Choice C is incorrect as the LH surge usually precedes ovulation by around 24-36 hours, not 12 hours.

During a genetic evaluation, it is discovered that the woman is carrying one autosomal dominant gene for a serious late adult–onset disease, while her partner's history is unremarkable. Based on this information, which of the following family members should be considered high risk and in need of genetic counseling? Select all that apply.
- A. The woman's fetus.
- B. The woman's sisters.
- C. The woman's brothers.
- D. The woman's parents.
Correct Answer: A
Rationale: All first-degree relatives and offspring are at risk for inheriting the gene.
What is the purpose of progesterone supplementation after embryo transfer in IVF?
- A. To induce ovulation for the next cycle.
- B. To support the uterine lining and enhance implantation success.
- C. To suppress natural hormone levels for better control.
- D. To eliminate the risk of multiple pregnancies.
Correct Answer: B
Rationale: The correct answer is B: To support the uterine lining and enhance implantation success. Progesterone supplementation is crucial after embryo transfer in IVF because it helps prepare the uterine lining for implantation and provides hormonal support to maintain a pregnancy. Progesterone is essential for the embryo to implant and for the early stages of pregnancy to progress. Therefore, the purpose of progesterone supplementation is to enhance the chances of successful implantation and support early pregnancy development.
Choices A, C, and D are incorrect:
A: To induce ovulation for the next cycle - Progesterone supplementation is not used to induce ovulation after embryo transfer in IVF. Ovulation should have already occurred before the embryo transfer.
C: To suppress natural hormone levels for better control - Progesterone supplementation is not used to suppress hormone levels but rather to support hormonal balance during the implantation phase.
D: To eliminate the risk of multiple pregnancies - Progesterone
A patient asks about the effects of smoking on male fertility. What should the nurse include in the response?
- A. Smoking increases testosterone levels, improving fertility.
- B. Smoking affects sperm count, motility, and morphology.
- C. Smoking has no significant impact on male reproductive health.
- D. Smoking only affects fertility when combined with alcohol use.
Correct Answer: B
Rationale: The correct answer is B because smoking has been proven to negatively impact male fertility by reducing sperm count, motility, and morphology. Nicotine and other harmful chemicals in cigarettes can damage sperm DNA and affect reproductive health. Choice A is incorrect as smoking actually decreases testosterone levels. Choice C is incorrect as smoking does have a significant impact on male reproductive health. Choice D is incorrect because smoking alone can still affect male fertility without the need for alcohol use.
During an IVF cycle, a patient asks about embryo transfer timing. What is the nurse's best explanation?
- A. Embryos are always transferred on the day of fertilization.
- B. Embryo transfer typically occurs 3 to 5 days after fertilization.
- C. Timing depends on uterine size, not embryo development.
- D. Transfer is done after pregnancy is confirmed.
Correct Answer: B
Rationale: The correct answer is B: Embryo transfer typically occurs 3 to 5 days after fertilization. This timing aligns with the development of embryos to the blastocyst stage, which is crucial for successful implantation in the uterus. By waiting until this stage, the chances of a successful pregnancy are increased. Choice A is incorrect because embryos do not reach the blastocyst stage on the day of fertilization. Choice C is incorrect as embryo development stage is a key factor in determining the timing of transfer. Choice D is incorrect as waiting until pregnancy is confirmed would delay the transfer unnecessarily.
A nurse is educating a male patient about improving sperm quality. What should the nurse suggest?
- A. Increase exposure to saunas and hot tubs for relaxation.
- B. Maintain a healthy lifestyle, including balanced nutrition and avoiding smoking.
- C. Consume high-fat diets to enhance testosterone levels.
- D. Avoid exercise as it reduces sperm motility.
Correct Answer: B
Rationale: The correct answer is B: Maintain a healthy lifestyle, including balanced nutrition and avoiding smoking. This is because a healthy lifestyle promotes overall well-being and can positively impact sperm quality. Balanced nutrition provides essential nutrients for sperm production while avoiding smoking reduces oxidative stress that can harm sperm.
Choice A is incorrect because increased exposure to saunas and hot tubs can actually raise scrotal temperature, potentially harming sperm quality. Choice C is incorrect as high-fat diets can lead to obesity and negatively impact sperm quality. Choice D is incorrect as exercise is beneficial for overall health, including sperm motility.
