Nursing Elites

1. A client receiving total parenteral nutrition (TPN) through a central line suddenly develops dyspnea, chest pain, and a drop in blood pressure. What should the nurse do first?

• A. Stop the TPN infusion.
• B. Notify the healthcare provider.
• C. Place the client in Trendelenburg position.
• D. Administer oxygen at 2 liters/minute.

Correct answer: C

Rationale: Placing the client in Trendelenburg position should be the initial action as it can help manage a suspected air embolism, a potential complication of TPN administration. This position helps trap air in the apex of the atrium, reducing the risk of air reaching the pulmonary circulation and causing further harm. Once the client is in a safe position, further actions such as stopping the TPN infusion, notifying the healthcare provider, and administering oxygen can be taken as appropriate.

2. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

• A. Serum sodium.
• B. Serum potassium.
• C. Serum calcium.
• D. Serum magnesium.

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.

3. A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?

• A. Increased blood pressure.
• B. Lowered cholesterol levels.
• C. Decreased heart rate.
• D. Improved liver function.

Correct answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.

4. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

5. A male infant born at 30-weeks gestation at an outlying hospital is being prepared for transport to a Level IV neonatal facility. His respirations are 90/min, and his heart rate is 150 beats per minute. Which drug is the transport team most likely to administer to this infant?

• A. Ampicillin (Omnipen) 25 mg/kg slow IV push.
• B. Gentamicin sulfate (Garamycin) 2.5 mg/kg IV.
• C. Digoxin (Lanoxin) 20 micrograms/kg IV.
• D. Beractant (Survanta) 100 mg/kg per endotracheal tube.

Correct answer: D

Rationale: In this scenario, the infant is a preterm neonate with respiratory distress and is being transported to a Level IV neonatal facility. The drug most likely to be administered by the transport team is Beractant (Survanta) via endotracheal tube. Beractant is a surfactant used to treat respiratory distress syndrome in preterm infants by improving lung compliance and reducing the need for mechanical ventilation.
