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.

What is the significance of basal body temperature (BBT) tracking in fertility?
- A. BBT predicts the exact time of ovulation.
- B. A rise in BBT confirms that ovulation has occurred.
- C. BBT tracking eliminates the need for ovulation predictor kits.
- D. BBT remains constant throughout the menstrual cycle.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. BBT rise confirms ovulation due to increased progesterone post-ovulation.
2. Progesterone causes a slight increase in BBT, signaling the release of an egg.
3. The shift in BBT helps predict the fertile window for conception.
4. BBT tracking does not predict the exact time of ovulation (A), nor eliminate the need for ovulation predictor kits (C), and BBT does not remain constant throughout the cycle (D).
A nurse working in an infertility clinic should include which of the following in her discussions with the couple?

A nurse is instructing a woman on the use of ovulation predictor kits. What should the nurse tell the client?
- 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 2 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 2 days, maximizing chances of conception. Choice A is incorrect as ovulation predictor kits are typically over-the-counter. Choice B is incorrect as the kit measures urinary LH, not serum. Choice C is incorrect as the LH surge usually occurs 24-36 hours before ovulation, not 12.
A nurse is offering preconception counseling in a primary care clinic. Which statement by a patient indicates a need for correction?
- A. Pregnancy rates are not related to the age of the male partner.
- B. Sexually active males should be routinely tested for STIs and treated appropriately.
- C. Maintaining a healthy weight is important for the reproductive health of both female and male partners.
- D. Certain medications, such as testosterone supplementation and chemotherapy, can impact male fertility.
Correct Answer: A
Rationale: The correct answer is A. Pregnancy rates are indeed related to the age of the male partner because sperm quality and quantity decline with age. This is crucial information in preconception counseling. Choice B is correct as STI testing for sexually active males is important for reproductive health. Choice C is correct as maintaining a healthy weight is crucial for both partners' fertility. Choice D is correct as certain medications can impact male fertility. In summary, the incorrect choice (A) contradicts established knowledge about male age and fertility, making it the correct answer.

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.
