1. As women reach the end of their childbearing years, does ovulation become more regular?

• A. TRUE
• B. FALSE
• C. Rarely
• D. Always

Correct answer: B

Rationale: The correct answer is B: FALSE. As women age and reach the end of their childbearing years, ovulation becomes less regular due to hormonal changes associated with menopause. This can result in irregular ovulation patterns or even the cessation of ovulation entirely. Choice A is incorrect because ovulation does not become more regular with age. Choices C and D are also incorrect as they do not accurately reflect the changes in ovulation patterns that occur as women approach the end of their childbearing years.

2. According to a study in 2014 by Skakkebaek et al., who among the following is most likely to have gynecomastia?

• A. Jennifer, a dancer, who has Down syndrome
• B. Frank, a teacher, who is diagnosed with XYY syndrome
• C. Peter, a fashion designer, who has Klinefelter syndrome
• D. Ria, a gym instructor, who is diagnosed with Turner syndrome

Correct answer: C

Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY) and typically have reduced testosterone levels, which can lead to gynecomastia (enlarged breasts). This condition is not usually associated with Down syndrome (choice A), XYY syndrome (choice B), or Turner syndrome (choice D), making them less likely to have gynecomastia.

3. A newborn is being assessed by a nurse who was born post-term. Which of the following findings should the nurse expect?

• A. Nails extending over tips of fingers
• B. Large deposits of subcutaneous fat
• C. Pale, translucent skin
• D. Thin covering of fine hair on shoulders and back

Correct answer: A

Rationale: Post-term newborns often have longer nails that extend over the tips of their fingers due to the extended gestation period. This occurs because the baby continues to grow in utero past the typical 40 weeks of gestation. Choices B, C, and D are incorrect as large deposits of subcutaneous fat, pale translucent skin, and a thin covering of fine hair on shoulders and back are not typically associated with post-term newborns. Longer nails are a common finding in post-term newborns due to the prolonged time spent in the womb, allowing for more nail growth compared to infants born at term.

4. A nurse is developing an educational program about hemolytic diseases in newborns for a group of newly licensed nurses. Which of the following genetic information should the nurse include in the program as a cause of hemolytic disease?

• A. The mother is Rh positive, and the father is Rh negative
• B. The mother is Rh negative, and the father is Rh positive
• C. The mother and the father are both Rh positive
• D. The mother and the father are both Rh negative

Correct answer: B

Rationale: The correct answer is B: 'The mother is Rh negative, and the father is Rh positive.' Hemolytic disease of the newborn occurs when an Rh-negative mother carries an Rh-positive fetus, leading to Rh incompatibility. In this scenario, the mother produces antibodies against the Rh antigen present in the fetus, which can result in hemolysis of the fetal red blood cells. Choices A, C, and D do not describe the Rh incompatibility that leads to hemolytic disease in newborns. Therefore, they are incorrect.

5. How many pairs of autosomes does a human zygote contain?

• A. 46
• B. 44
• C. 23
• D. 22

Correct answer: D

Rationale: A human zygote contains 22 pairs of autosomes and one pair of sex chromosomes, totaling 46 chromosomes. Therefore, the correct answer is 22. Choices A, B, and C are incorrect because they do not accurately represent the number of autosomes in a human zygote. Option A (46) represents the total number of chromosomes in a human zygote, not the number of autosomes. Option B (44) is incorrect as it does not account for the correct number of autosomes. Option C (23) is inaccurate since it represents the total number of chromosomes in a human gamete, not the number of autosomes in a zygote.
