A nurse is discussing lifestyle changes to optimize fertility. Which recommendation is accurate?
- A. Avoid moderate exercise to conserve energy for conception.
- B. Quit smoking to improve reproductive health.
- C. Eliminate all carbohydrates from the diet.
- D. Increase caffeine intake to boost energy levels.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
- Smoking is known to have negative effects on reproductive health, reducing fertility in both men and women.
- Quitting smoking can improve reproductive outcomes and increase chances of conception.
- Smoking can harm egg and sperm quality, leading to infertility issues.
- Other choices are incorrect as moderate exercise, carbohydrates, and increased caffeine intake do not directly impact fertility.

The nurse in a genetic clinic interviews a couple and develops a pedigree chart. Which inheritance patterns does the pedigree chart portray?
- A. Autosomal recessive
- B. X-linked recessive
- C. Autosomal dominant
- D. X-linked dominant
Correct Answer: C
Rationale: The correct answer is C, Autosomal dominant. In an autosomal dominant inheritance pattern, the trait is passed down from generation to generation, affecting both males and females equally. This is indicated by the presence of the trait in every generation of the pedigree chart. In contrast, autosomal recessive traits would skip generations and require both parents to be carriers. X-linked recessive traits mainly affect males and skip generations. X-linked dominant traits would be present in every generation but would affect more females than males.
A nurse is offering preconception counseling to a couple. What advice should be emphasized to support fertility?
- A. Smoking cessation improves both male and female fertility.
- B. Caffeine intake has no impact on fertility.
- C. Stress management is unnecessary if ovulation occurs regularly.
- D. High protein diets guarantee improved egg quality.
Correct Answer: A
Rationale: The correct answer is A: Smoking cessation improves both male and female fertility. Smoking negatively impacts fertility by reducing sperm quality, disrupting hormone production, and affecting egg quality. By quitting smoking, both partners can improve their chances of conceiving.
Summary:
B: Caffeine intake can affect fertility, so moderate consumption is recommended.
C: Stress management is important for fertility, as stress can disrupt hormonal balance.
D: High protein diets alone do not guarantee improved egg quality; a balanced diet is essential for fertility.
What is the purpose of ovarian reserve testing in fertility assessments?
- A. To predict the likelihood of multiple pregnancies.
- B. To estimate the quantity and quality of a woman's remaining eggs.
- C. To assess uterine health and readiness for implantation.
- D. To monitor hormone levels during pregnancy.
Correct Answer: B
Rationale: The purpose of ovarian reserve testing in fertility assessments is to estimate the quantity and quality of a woman's remaining eggs. This is crucial in determining a woman's fertility potential and likelihood of success with fertility treatments. By assessing ovarian reserve, healthcare providers can gauge how many eggs a woman has left and how well they are likely to respond to fertility treatments such as in vitro fertilization (IVF). This information is essential for personalized fertility planning. Choices A, C, and D are incorrect as they do not directly relate to the main purpose of ovarian reserve testing, which is specifically focused on evaluating a woman's egg quantity and quality.
During a consultation, a patient asks about egg freezing. What should the nurse emphasize?
- A. Egg freezing is only for women over 35.
- B. The quality of eggs decreases with age, so earlier freezing is recommended.
- C. Frozen eggs can only be used within five years.
- D. Egg freezing eliminates the need for hormonal treatments.
Correct Answer: B
Rationale: The correct answer is B because the quality of eggs decreases with age due to biological factors, making earlier egg freezing more effective. Freezing eggs at a younger age preserves better quality eggs for future use in assisted reproduction techniques. Choice A is incorrect as egg freezing is not limited to women over 35. Choice C is incorrect as frozen eggs can be stored for much longer than five years. Choice D is incorrect because egg freezing does not eliminate the need for hormonal treatments; it simply preserves eggs for future use.
What is the role of hCG injections in fertility treatments?
- A. To prevent ovulation during stimulation cycles.
- B. To trigger the release of mature eggs from the ovary.
- C. To enhance the quality of embryos for transfer.
- D. To suppress uterine contractions post-implantation.
Correct Answer: B
Rationale: The correct answer is B: To trigger the release of mature eggs from the ovary. hCG injections are commonly used in fertility treatments to induce ovulation by mimicking the hormone LH, which triggers the release of mature eggs from the ovary. This is crucial for assisted reproductive techniques like in vitro fertilization.
A: Incorrect. hCG injections do not prevent ovulation; instead, they promote it.
C: Incorrect. hCG injections do not directly enhance the quality of embryos.
D: Incorrect. hCG injections are not used to suppress uterine contractions post-implantation; they are primarily for ovulation induction.
