- A. Preexisting diagnosis of herpes simplex 2.

The nurse is educating a patient about the role of luteal phase support in fertility treatments. What should be emphasized?
- A. It involves increasing estrogen levels to support ovulation.
- B. It requires progesterone supplementation to maintain uterine lining integrity.
- C. It eliminates the need for hormonal monitoring during treatments.
- D. It helps prevent the LH surge during ovulation induction.
Correct Answer: B
Rationale: The correct answer is B because luteal phase support is crucial in fertility treatments to maintain the uterine lining for potential embryo implantation. Progesterone supplementation is necessary to support this phase, as it ensures a hospitable environment for the embryo. Option A is incorrect because luteal phase support primarily focuses on progesterone, not estrogen. Option C is incorrect as hormonal monitoring is still essential during fertility treatments. Option D is incorrect because luteal phase support does not prevent the LH surge, which is necessary for ovulation.
The nurse is counseling a couple about infertility. Which piece of assessment data may affect the woman's ability to become pregnant?
- A. The woman exercises three times a week for 1 hour.
- B. The couple each consumes a glass of wine each night.
- C. The couple has a sauna in their backyard.
- D. The male partner works on heavy machinery.
Correct Answer: C
Rationale: The correct answer is C. Having a sauna in the backyard may affect the woman's ability to become pregnant due to the potential negative impact of excessive heat on sperm production and ovulation. Saunas can raise body temperature, which can be harmful to sperm and reduce fertility.
Explanation of other choices:
A: Regular exercise is generally beneficial for fertility and overall health, so this is unlikely to significantly impact the woman's ability to become pregnant.
B: Consuming a glass of wine each night in moderation is not likely to have a significant impact on fertility unless it leads to excessive alcohol consumption.
D: Working on heavy machinery may pose risks to male fertility due to potential exposure to harmful chemicals or radiation, but this choice doesn't directly impact the woman's ability to become pregnant.
A client is to undergo a postcoital test for infertility. The nurse should include which of the following statements in the client's preprocedure counseling?
- A. You will have the test the day after your menstruation ends.
- B. You will have a dye put into your vein that will show up on x-ray.
- C. You should refrain from having intercourse for the four days immediately prior to the test.
- D. You should experience the same sensations you feel when your doctor does your Pap test.
Correct Answer: D
Rationale: The postcoital test involves assessing cervical mucus after intercourse, similar to a Pap test.
During an infertility consultation, the nurse explains the impact of endometriosis on fertility. What should the nurse emphasize?
- A. Endometriosis improves the chances of conception naturally.
- B. Endometriosis can cause scarring and reduce ovarian function.
- C. Endometriosis is unrelated to infertility.
- D. Endometriosis eliminates the need for fertility treatments.
Correct Answer: B
Rationale: The correct answer is B because endometriosis can lead to scarring in the reproductive organs and reduce ovarian function, affecting fertility. Scarring can block the fallopian tubes, impairing egg and sperm transport. Reduced ovarian function can affect egg quality and quantity. Choices A, C, and D are incorrect. Endometriosis does not improve natural conception chances; it is a leading cause of infertility. It is related to infertility due to its impact on reproductive organs. Endometriosis often necessitates fertility treatments due to its effects on fertility.
