Nursing Elites

1. When discussing risk factors for gestational diabetes mellitus (GDM) with a group of pregnant clients, which ethnicity should the nurse identify as having the lowest incidence of GDM?

• A. Asian
• B. Non-Hispanic White American
• C. Hispanic
• D. African American

Correct answer: B

Rationale: Non-Hispanic White Americans have the lowest incidence of gestational diabetes mellitus (GDM) compared to other ethnicities. This is because GDM is more prevalent among certain ethnic groups, such as Asian, Hispanic, and African American populations. Asian individuals have an increased risk of developing GDM due to genetic factors, while Hispanic and African American populations have higher incidences of GDM due to lifestyle and genetic predispositions. Therefore, the correct answer is B, as Non-Hispanic White Americans generally have a lower risk of developing GDM.

2. What is the typical sex chromosome pattern for males?

• A. XX
• B. XYY
• C. XY
• D. XXY

Correct answer: C

Rationale: The correct answer is C: XY. In males, the typical sex chromosome pattern consists of one X chromosome and one Y chromosome. Choice A (XX) is the sex chromosome pattern for females. Choice B (XYY) is a chromosomal disorder where males have an extra Y chromosome. Choice D (XXY) is the sex chromosome pattern associated with Klinefelter syndrome, a condition where males have an extra X chromosome.

3. A client has bacterial vaginosis. Which of the following medications should the nurse expect to administer?

• A. Metronidazole
• B. Fluconazole
• C. Acyclovir
• D. Clindamycin

Correct answer: A

Rationale: Metronidazole is the correct choice for treating bacterial vaginosis as it is the first-line medication recommended for this condition. Metronidazole works by disrupting the DNA structure of bacteria, making it an effective treatment. Choice B, Fluconazole, is an antifungal medication primarily used for treating fungal infections, not bacterial vaginosis. Choice C, Acyclovir, is an antiviral medication used to treat viral infections, not bacterial vaginosis. Choice D, Clindamycin, is also used to treat bacterial infections but is not the first-line treatment for bacterial vaginosis, making it an incorrect choice in this scenario.

4. 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.

5. What is the primary role of meiosis in the production of sperm and ova?

• A. To reduce the chromosome number by half
• B. To increase the chromosome number
• C. To create identical copies of chromosomes
• D. To repair damaged chromosomes

Correct answer: A

Rationale: The correct answer is A. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of sperm and ova. Choice B is incorrect because meiosis does not increase the chromosome number. Choice C is incorrect because meiosis creates genetically diverse gametes, not identical copies of chromosomes. Choice D is incorrect because meiosis does not primarily function to repair damaged chromosomes.
