Nursing Elites

1. 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.

2. A patient with ventricular tachycardia and a pulse needs electrical intervention. What is the appropriate action?

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

Correct answer: B

Rationale: For a patient with ventricular tachycardia and a pulse, the appropriate action is synchronized cardioversion. Defibrillation is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing is typically used for bradycardias. Medication administration may be considered in stable ventricular tachycardia cases but electrical intervention is preferred for immediate correction in this scenario.

3. What are the early signs of hypokalemia on an ECG?

• A. Flattened T waves
• B. Elevated ST segments
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

4. A client with heart failure is prescribed furosemide 20 mg PO twice daily. Which of the following instructions should the nurse include during discharge teaching?

• A. Monitor for increased blood pressure
• B. Increase intake of high-potassium foods
• C. Expect an increase in swelling in the hands and feet
• D. Take the second dose at bedtime

Correct answer: B

Rationale: The correct answer is to instruct the client to increase their intake of high-potassium foods. Furosemide can lead to hypokalemia, a condition of low potassium levels in the blood. Increasing the consumption of high-potassium foods helps prevent this adverse effect. Monitoring for increased blood pressure (choice A) is not directly related to furosemide use. Expecting an increase in swelling (choice C) is incorrect as furosemide is a diuretic that helps reduce swelling. Taking the second dose at bedtime (choice D) is not necessary unless prescribed by the healthcare provider.

5. A nurse administers insulin for a misread glucose level. What should the nurse monitor for?

• A. Monitor for hypoglycemia
• B. Monitor for hyperglycemia
• C. Monitor for hyperkalemia
• D. Document the incident

Correct answer: A

Rationale: When a nurse administers insulin for a misread glucose level, they should monitor for hypoglycemia. Insulin lowers blood sugar levels, so the patient may experience hypoglycemia if given insulin unnecessarily. Monitoring for hypoglycemia involves observing for symptoms such as shakiness, sweating, dizziness, confusion, and palpitations. Choices B and C are incorrect because administering insulin for a misread glucose level would lower blood sugar levels, resulting in hypoglycemia, not hyperglycemia or hyperkalemia. Choice D is not the immediate priority; the focus should be on patient safety and monitoring for potential adverse effects of the unnecessary insulin.
