A nurse is caring for a client with congestive heart failure who is prescribed a beta-blocker. The nurse should instruct the client to:

Avoid abrupt discontinuation of the medication.

Take the medication with a high-fat meal.

Limit fluid intake to prevent fluid overload.

Take the medication in the evening to promote sleep.

Answer and Explanation

The Correct Answer is A

A) This choice is correct. Beta-blockers should not be abruptly discontinued, as sudden discontinuation can lead to rebound effects and worsen the client's condition. Gradual tapering of the medication is necessary under the guidance of the healthcare provider.

B) This choice is incorrect because taking a beta-blocker with a high-fat meal is not necessary. Beta-blockers can be taken with or without food, but consistent administration is essential for optimal therapeutic effects.

C) This choice is incorrect because limiting fluid intake is not specific to the administration of beta-blockers. Fluid intake may need to be adjusted based on the client's overall fluid balance and congestive heart failure status, but it is not a direct instruction related to the medication.

D) This choice is incorrect because the timing of beta-blocker administration varies depending on the specific beta-blocker prescribed and the client's individual response. Some beta-blockers may be taken in the morning, while others may be taken in the evening. The client should follow the prescribed schedule given by the healthcare provider.

Correct Answer is D

Explanation

A) This choice is incorrect because loop diuretics can lead to increased sodium excretion, potentially causing hypernatremia (high sodium levels) rather than hyponatremia (low sodium levels).

B) This choice is incorrect because loop diuretics do not typically cause hypocalcemia (low calcium levels). They primarily affect sodium, potassium, and water excretion.

C) This choice is incorrect because loop diuretics are more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia (high potassium levels). Loop diuretics can increase potassium excretion, leading to a potential deficiency.

D) This choice is correct. Loop diuretics are potent potassium-wasting diuretics, meaning they increase potassium excretion in the urine, potentially causing hypokalemia. The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.

A. Bradycardia B. Hypokalemia C. Hypertension D. Hyperglycemia

Correct Answer is B

Explanation

A) This choice is incorrect because bradycardia (slow heart rate) is not a common adverse effect of furosemide, a loop diuretic.

B) This choice is correct. Furosemide is a loop diuretic that can lead to increased potassium excretion in the urine, potentially causing hypokalemia (low potassium levels). The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.

C) This choice is incorrect because hypertension (high blood pressure) is not typically associated with loop diuretics like furosemide. In fact, furosemide is used to treat hypertension and congestive heart failure by promoting the excretion of excess fluid and reducing blood pressure.

D) This choice is incorrect because hyperglycemia (high blood glucose levels) is not a common adverse effect of furosemide. In fact, furosemide can sometimes cause transient hypoglycemia.
