Nursing Elites

1. What dietary instructions should be provided for a patient with pre-dialysis end-stage kidney disease?

• A. Limit phosphorus intake to 700 mg/day
• B. Increase protein intake to 1g/kg/day
• C. Increase sodium intake
• D. Avoid potassium-rich foods

Correct answer: A

Rationale: Patients with pre-dialysis end-stage kidney disease should limit phosphorus intake to manage their condition. Excessive phosphorus can lead to mineral and bone disorders in patients with kidney disease. Choices B, C, and D are incorrect. Increasing protein intake is not recommended as it can burden the kidneys. Increasing sodium intake is usually discouraged due to its association with hypertension and fluid retention in kidney disease. Avoiding potassium-rich foods is more relevant in advanced kidney disease stages when potassium levels are high, not in pre-dialysis end-stage kidney disease.

2. A nurse misreads a glucose level and administers insulin for a blood glucose of 210 mg/dL instead of 120 mg/dL. What is the priority intervention?

• A. Monitor for hypoglycemia
• B. Monitor for hyperkalemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. In this scenario, the nurse administered insulin based on a misread glucose level, which could lead to hypoglycemia due to excessive insulin action lowering blood glucose levels. Monitoring for hypoglycemia allows for prompt recognition and intervention if blood glucose levels drop significantly. Choice B, monitoring for hyperkalemia, is incorrect as administering insulin would not cause hyperkalemia. Choice C, administering glucose IV, is not appropriate at this time since the patient's blood glucose level is already elevated. Choice D, documenting the incident, is important but not the priority at this moment when patient safety is at risk due to potential hypoglycemia.

3. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. A blockage in the chest tube
• C. Normal chest tube function
• D. Malfunction in the drainage system

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the chest tube system. This bubbling occurs when air is escaping through the tube and entering the water seal chamber. Choice B, a blockage in the chest tube, is incorrect as continuous bubbling does not suggest a blockage. Choice C, normal chest tube function, is incorrect because continuous bubbling is not an expected finding in a properly functioning chest tube. Choice D, a malfunction in the drainage system, is incorrect as continuous bubbling specifically points towards an air leak, not a general malfunction.

4. What is the preferred electrical intervention for a patient with ventricular tachycardia and a pulse?

• A. Synchronized cardioversion
• B. Defibrillation
• C. Medication administration
• D. Pacing

Correct answer: A

Rationale: In a patient with ventricular tachycardia and a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat unstable tachyarrhythmias like ventricular tachycardia with a pulse. Choice B, defibrillation, is used for pulseless ventricular tachycardia or ventricular fibrillation. Choice C, medication administration, may not provide immediate correction for unstable ventricular tachycardia. Choice D, pacing, is not the first-line treatment for ventricular tachycardia with a pulse.

5. What ECG changes are associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: Hyperkalemia is known to cause ST depression on an ECG. Flattened T waves are more commonly seen in hypokalemia. Prominent U waves are associated with hypokalemia rather than hyperkalemia. Elevated ST segments are not typical findings in hyperkalemia.
