Nursing Elites

1. Before meiosis, a sperm cell:

• A. contains 46 chromosomes.
• B. contains two X chromosomes.
• C. is significantly larger than an egg cell.
• D. contains both an X and a Y chromosome.

Correct answer: A

Rationale: Before meiosis, a sperm cell contains 46 chromosomes. This is because sperm cells, like other somatic cells, have a diploid number of chromosomes. During meiosis, the number of chromosomes is halved to 23 to combine with an egg cell during fertilization. Choice B is incorrect because a sperm cell carries either an X or a Y chromosome, not both (Choice D). Choice C is incorrect as sperm cells are generally smaller than egg cells, which is an adaptation that aids in motility and penetration of the egg during fertilization.

2. A client at 38 weeks gestation is admitted to labor and delivery with a complaint of contractions 5 minutes apart. While the client is in the bathroom changing into a hospital gown, the nurse hears the noise of a baby. What should the nurse do first?

• A. Push the call light for help
• B. Inspect the client's perineum
• C. Notify a healthcare provider
• D. Turn on the infant warmer

Correct answer: B

Rationale: Inspecting the client's perineum immediately is necessary to assess if the baby is being delivered, which would require urgent action. Pushing the call light for help (Choice A) may delay the assessment and immediate action needed. Notifying a healthcare provider (Choice C) might cause further delays, as the situation requires urgent attention. Turning on the infant warmer (Choice D) is not the priority; ensuring safe delivery and assessment of the baby's condition come first.

3. A primiparous woman presents in labor with the following labs: hemoglobin 10.9 g/dL, hematocrit 29%, hepatitis surface antigen positive, Group B Streptococcus positive, and rubella non-immune. Which intervention should the nurse implement?

• A. Transfuse 2 units of packed red blood cells.
• B. Give measles, mumps, rubella vaccine 0.5 mL.
• C. Administer ampicillin 2 grams intravenously.
• D. Inject hepatitis B immune globulin 0.5 milliliters.

Correct answer: C

Rationale: The correct intervention in this scenario is to administer ampicillin 2 grams intravenously. This is crucial to prevent Group B Streptococcus infection in the newborn during delivery. Option A, transfusing packed red blood cells, is not indicated based on the hemoglobin and hematocrit levels provided. Option B, giving measles, mumps, rubella vaccine, is not necessary at this time. Option D, injecting hepatitis B immune globulin, is not appropriate for the conditions presented in the question.

4. Which of the following most accurately describes the function of genes?

• A. They regulate the development of traits.
• B. They prevent foreign particles from entering the body.
• C. They work together with lutein to influence development.
• D. They transfer oxygen from the bloodstream to other parts of the body.

Correct answer: A

Rationale: The correct answer is A: 'They regulate the development of traits.' Genes play a crucial role in regulating the development of traits by encoding proteins that control various bodily functions and characteristics. This process involves gene expression and the production of proteins that ultimately determine an individual's traits. Choice B is incorrect because genes do not have a direct role in preventing foreign particles from entering the body; this function is primarily carried out by the immune system. Choice C is incorrect as genes do not specifically work with lutein to influence development; genes operate independently to regulate trait expression. Choice D is incorrect as genes are not responsible for transferring oxygen in the bloodstream; this function is carried out by red blood cells and hemoglobin.

5. A client who is 24 weeks gestation arrives at the clinic reporting swollen hands. On examination, the nurse notes the client has had a rapid weight gain over six weeks. Which action should the nurse implement next?

• A. Review the client's previous blood pressures in the chart.
• B. Obtain the client's blood pressure.
• C. Observe and time the client's contractions.
• D. Examine the client for pedal edema.

Correct answer: B

Rationale: Swollen hands and rapid weight gain could be signs of preeclampsia, so the next step is to check the client's blood pressure. Elevated blood pressure is a key indicator in assessing for preeclampsia in pregnancy. Reviewing the client's previous blood pressures may provide additional context but obtaining the current blood pressure is crucial for immediate assessment. Observing and timing contractions are not relevant in this scenario as the client is not presenting with signs of active labor. Examining for pedal edema is important in assessing for fluid retention, but obtaining the blood pressure takes precedence in this case due to the potential seriousness of preeclampsia.
