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 at 11 weeks of gestation reports slight occasional vaginal bleeding over the past 2 weeks. Following an examination, the provider informs the client that the fetus has died, indicating a:

• A. Incomplete miscarriage
• B. Missed miscarriage
• C. Inevitable miscarriage
• D. Complete miscarriage

Correct answer: B

Rationale: A missed miscarriage, also known as a silent or delayed miscarriage, occurs when the embryo or fetus has died, but no bleeding or contractions have occurred to expel it from the uterus. In this scenario, the client's experiencing slight occasional vaginal bleeding over the past two weeks indicates a missed miscarriage as the fetus has died, but the body has not recognized the loss or expelled the products of conception.

3. 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.

4. 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.

5. A client is receiving positive-pressure mechanical ventilation. Which of the following interventions should the nurse implement to prevent complications? (Select one that doesn't apply.)

• A. Elevate the head of the bed to at least 30�.
• B. Apply restraints if the client becomes agitated.
• C. Administer pantoprazole as prescribed.
• D. Reposition the endotracheal tube to the opposite side of the mouth daily.

Correct answer: D

Rationale: Repositioning the endotracheal tube to the opposite side of the mouth daily is not a standard practice in preventing complications in a client receiving positive-pressure mechanical ventilation. This action may disrupt the secure placement of the endotracheal tube and increase the risk of complications. Elevating the head of the bed to at least 30� helps prevent aspiration and ventilator-associated pneumonia. Applying restraints if the client becomes agitated helps maintain the safety of the client by preventing self-extubation or accidental dislodgement of tubes. Administering pantoprazole as prescribed helps prevent stress ulcers, a common complication in critically ill patients on mechanical ventilation.
