Nursing Elites

1. 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.

2. 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.

3. 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.

4. 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.

5. A client who experienced a cesarean birth due to dysfunctional labor expresses disappointment for not having a natural childbirth. Which response should the nurse make?

• A. Validate the client's feelings by saying, 'It sounds like you are feeling sad that things didn't go as planned.'
• B. Assure the client by stating, 'At least you know you have a healthy baby.'
• C. Encourage the client by suggesting, 'Maybe next time you can have a vaginal delivery.'
• D. Provide information by saying, 'You can resume sexual relations sooner than if you had delivered vaginally.'

Correct answer: A

Rationale: The correct response is to acknowledge and validate the client's feelings of disappointment. This empathetic approach demonstrates understanding and support for the client's emotional state, fostering a therapeutic nurse-client relationship. Options B, C, and D do not address the client's emotional needs or provide appropriate support in this situation.
