What is the purpose of performing a hysterosalpingogram (HSG) during fertility evaluation?
- A. To determine ovarian reserve and egg quality.
- B. To visualize the fallopian tubes and check for blockages.
- C. To assess hormone levels during the menstrual cycle.
- D. To evaluate the sperm motility in the uterine cavity.
Correct Answer: B
Rationale: Performing a hysterosalpingogram (HSG) during fertility evaluation helps visualize the fallopian tubes and check for blockages. This is crucial as blocked fallopian tubes can prevent eggs from meeting sperm, leading to infertility. By injecting contrast dye into the uterus and taking X-ray images, doctors can assess tubal patency. This procedure is not aimed at determining ovarian reserve or egg quality (option A), assessing hormone levels (option C), or evaluating sperm motility in the uterine cavity (option D), as these factors are assessed through different tests and procedures.

A couple who has sought fertility counseling has been told that the man's sperm count is very low. The nurse advises the couple that spermatogenesis is impaired when which of the following occurs?
- A. The testes are overheated.
- B. The vas deferens is ligated.
- C. The prostate gland is enlarged.
- D. The flagella are segmented.
Correct Answer: A
Rationale: Overheating of the testes impairs spermatogenesis, as sperm production requires a cooler environment.
A patient asks about the effects of environmental toxins on fertility. What should the nurse explain?
- A. Environmental toxins have no impact on fertility outcomes.
- B. Exposure to toxins can harm egg and sperm quality, reducing fertility.
- C. Toxins only affect fertility in individuals over 40.
- D. Avoiding toxins guarantees immediate conception.
Correct Answer: B
Rationale: The correct answer is B because exposure to environmental toxins can indeed harm egg and sperm quality, leading to reduced fertility. Toxins can disrupt hormone balance, affect reproductive organs, and damage genetic material in eggs and sperm. This can result in difficulty conceiving or increased risk of miscarriage. Choices A, C, and D are incorrect. A is inaccurate as environmental toxins can impact fertility outcomes. C is incorrect as toxins can affect fertility at any age. D is misleading as avoiding toxins does not guarantee immediate conception, as fertility is influenced by various factors.
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 explaining the importance of lifestyle changes for women trying to conceive. What should the nurse emphasize?
- A. Focus solely on diet; exercise is not relevant to fertility.
- B. Both a balanced diet and regular moderate exercise support reproductive health.
- C. Weight gain is beneficial regardless of current BMI.
- D. Avoid stress management as it has no effect on fertility.
Correct Answer: B
Rationale: The correct answer is B because both a balanced diet and regular moderate exercise support reproductive health. A balanced diet provides essential nutrients for fertility, while exercise helps regulate hormones and improve overall health, increasing chances of conception. Choice A is incorrect because exercise plays a crucial role in fertility. Choice C is incorrect as weight gain should be based on individual needs, not a general recommendation. Choice D is incorrect as stress management is important for fertility as stress can impact hormone levels and ovulation.

- B. the woman should immediately go to the hospital.
- C. The woman should take oral terbutaline every 2 hours for the next day.
- D. If the woman starts to bleed or to contract
Correct Answer: C
Rationale: Bleeding or contractions after CVS warrant medical attention.
