- A. Vitamin D is only necessary during the third trimester of pregnancy.
- B. It supports hormonal balance and may improve egg quality and implantation rates.

Lisa, a 35-year-old practicing attorney and marathon runner, presents to the clinic with a complaint of irregular menses. She tells the nurse, 'My husband and I want to start a family but it hasn't happened yet. We stopped using birth control 6 months ago. Should we be concerned?' What is the nurse's best response?
- A. Relax and it will happen.
- B. No, infertility is the failure to conceive after 1 year of unprotected intercourse.
- C. Aging and extreme exercise regimens may impact fertility. You should address your concerns with your provider during today's visit.
- D. Decreasing your exercise frequency and intensity will increase your chances of conceiving.
Correct Answer: C
Rationale: The correct answer is C because it acknowledges the potential impact of aging and extreme exercise on fertility, prompting further evaluation by the healthcare provider. Lisa's age and intense exercise regimen are important factors to consider since they can affect her ability to conceive. By addressing her concerns during the visit, the nurse can gather more information, assess potential fertility issues, and provide appropriate guidance or referrals.
Choice A is incorrect because it dismisses Lisa's concerns without addressing potential underlying issues. Choice B is incorrect as it sets a timeline for infertility diagnosis that is generally accepted after 1 year of unprotected intercourse for women under 35 years old, but Lisa's age and lifestyle may warrant earlier evaluation. Choice D is incorrect as it oversimplifies the issue by suggesting only a change in exercise routine as a solution without considering other potential factors impacting fertility.

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.
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

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.
