Nursing Elites

1. A newborn is born to a mother with poorly controlled type 2 diabetes. The newborn is macrosomic and presents with respiratory distress syndrome. The most likely cause of the respiratory distress is which of the following?

• A. Hyperinsulinemia
• B. Increased deposits of fat in the chest and shoulder area
• C. Brachial plexus injury
• D. Increased blood viscosity

Correct answer: A

Rationale: The correct answer is hyperinsulinemia. In infants born to mothers with poorly controlled diabetes, the excess glucose crosses the placenta, leading to fetal hyperglycemia. This results in fetal hyperinsulinemia, which in turn can cause macrosomia (large birth weight), increasing the risk of respiratory distress syndrome due to the immature lungs' inability to handle the increased workload. Hyperinsulinemia, not increased deposits of fat, brachial plexus injury, or increased blood viscosity, is the most likely cause of respiratory distress in this scenario.

2. A client with severe preeclampsia is receiving magnesium sulfate IV at 2 g/hr. Which of the following findings indicates that it is safe to continue the infusion?

• A. Diminished deep-tendon reflexes
• B. Respiratory rate of 16/min
• C. Urine output of 50 mL in 4 hours
• D. Heart rate of 56/min

Correct answer: B

Rationale: A respiratory rate of 16/min within the normal range is an essential parameter to monitor when administering magnesium sulfate, as respiratory depression is a potential adverse effect. Diminished deep-tendon reflexes may indicate magnesium toxicity, warranting immediate intervention. A urine output of 50 mL in 4 hours is below the expected amount, suggesting decreased kidney perfusion, which can be exacerbated by magnesium sulfate. A heart rate of 56/min is bradycardic and may indicate magnesium toxicity, requiring assessment and possible discontinuation of the infusion.

3. A client with preterm labor is being admitted. The nurse anticipates a prescription by the provider for which of the following medications?

• A. Prostaglandin E2
• B. Indomethacin
• C. Methylergonovine
• D. Oxytocin

Correct answer: B

Rationale: Indomethacin is used to delay premature labor by inhibiting uterine contractions. Prostaglandin E2, Methylergonovine, and Oxytocin are not typically used to manage preterm labor. Prostaglandin E2 can be used for cervical ripening and labor induction. Methylergonovine is used to prevent or control postpartum hemorrhage. Oxytocin is used for labor induction and augmentation of labor in term pregnancies.

4. When reviewing the arterial blood gas values for a client, a nurse notes a pH of 7.32, PaCO2 of 48 mm Hg, and HCO3 of 23 mEq/L. What does this indicate about the acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: The given values suggest respiratory acidosis. In respiratory acidosis, the pH is low (<7.35), PaCO2 is high (>45 mm Hg), and the HCO3 is normal or slightly elevated. In this scenario, the low pH (7.32) and high PaCO2 (48 mm Hg) indicate respiratory acidosis, where there is an excess of carbon dioxide in the blood, leading to acidification of the body fluids.

5. A nurse on the postpartum unit is caring for a group of clients with an assistive personnel (AP). Which of the following tasks should the nurse plan to delegate to the AP?

• A. Provide a sitz bath to a client who has a fourth-degree laceration and is 2 days postpartum.
• B. Observe an area of redness on the breast of a client who is 1 day postpartum.
• C. Monitor vital signs during admission of a client who has gestational hypertension.
• D. Change the perineal pad of a client who just transferred from labor and delivery.

Correct answer: A

Rationale: Delegating the task of providing a sitz bath to a client with a fourth-degree laceration and who is 2 days postpartum to the assistive personnel (AP) is appropriate. This task involves assisting the client with personal hygiene and comfort measures that can be safely performed by the AP under the supervision and direction of the nurse. Tasks like observing redness on the breast, monitoring vital signs during admission for gestational hypertension, and changing perineal pads may require a higher level of assessment and nursing judgment, making them more appropriate for the nurse to perform.
