Nursing Elites

1. A client is in the second stage of labor. Which of the following manifestations should the nurse expect?

• A. The client expels the placenta
• B. The client experiences gradual dilation of the cervix
• C. The client begins having regular contractions
• D. The client delivers the newborn

Correct answer: D

Rationale: During the second stage of labor, the cervix is fully dilated, and the client delivers the newborn. The expulsion of the placenta occurs during the third stage of labor, not the second stage. Regular contractions typically begin in the first stage of labor, not the second. Gradual dilation of the cervix occurs during the first stage of labor, specifically during the active phase.

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. 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.

4. A primigravida at 36 weeks gestation who is RH-negative experienced abdominal trauma in a motor vehicle collision. Which assessment finding is most important for the nurse to report to the healthcare provider?

• A. Fetal heart rate at 162 beats per minute
• B. Mild contractions every 10 minutes
• C. Trace of protein in the urine
• D. Positive fetal hemoglobin testing

Correct answer: D

Rationale: The correct answer is 'Positive fetal hemoglobin testing' (D). Positive fetal hemoglobin testing (Kleihauer-Betke test) indicates fetal-maternal hemorrhage, which is critical in an RH-negative mother due to the risk of isoimmunization. This condition can lead to sensitization of the mother's immune system against fetal blood cells, potentially causing hemolytic disease of the newborn in subsequent pregnancies. Reporting this finding promptly is crucial for appropriate management and interventions. Choices A, B, and C are not as critical in this scenario. While monitoring fetal heart rate and contractions is important, the detection of fetal-maternal hemorrhage takes precedence due to the serious implications it poses for the current and future pregnancies of an RH-negative mother.

5. In the context of an average ejaculation, which of the following statements is true about sperm?

• A. The average count of sperm in the ejaculate is 2.5 billion.
• B. Sperm in the ejaculate find the ovum by following the current of the fluid coming from the cervix.
• C. Only 1 in 1,000 sperm in the ejaculate will ever approach an ovum.
• D. Most of the sperm in the ejaculate move about in a random pattern in the vagina.

Correct answer: C

Rationale: Out of millions of sperm released during ejaculation, only a small fraction, about 1 in 1,000, will approach the ovum. This statement is true as sperm face many obstacles and challenges on their journey to reach and fertilize an ovum. Choice A is incorrect because the average count of sperm in an ejaculate is typically in the millions, not billions. Choice B is incorrect as sperm do not find the ovum by following the current of fluid; they navigate using other mechanisms. Choice D is incorrect because while some sperm may move randomly in the vagina, the ones that approach the ovum do so through a more purposeful and directed movement.
