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 B

Explanation

A) This choice is incorrect because while infections and viral illnesses can contribute to heart failure in some cases, they are not the leading causes of CHF. Hypertension and coronary artery disease are more common risk factors.

B) This choice is correct. Hypertension (high blood pressure) and coronary artery disease (narrowing or blockage of the heart's blood vessels) are the leading causes of CHF. Both conditions place increased stress on the heart and can lead to heart muscle damage and failure.

C) This choice is incorrect because while excessive physical exertion and overworking the heart can contribute to heart failure, they are not the primary causes of CHF. Underlying conditions like hypertension and coronary artery disease are more significant risk factors.

D) This choice is incorrect because anemia and low red blood cell count can impact heart function, but they are not the main causes of CHF. Hypertension and coronary artery disease are more commonly associated with the development of CHF.

A. Limit fluid intake to prevent fluid overload. B. Avoid foods high in potassium while on this medication. C. Take the medication in the morning to promote sleep. D. Monitor blood pressure daily and adjust the dose accordingly.

Correct Answer is B

Explanation

A) This choice is incorrect because limiting fluid intake is not specific to the administration of spironolactone. 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.

B) This choice is correct. Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia (high potassium levels). The client should avoid foods high in potassium to help prevent potassium overload and potential adverse effects.

C) This choice is incorrect because the timing of spironolactone administration may vary depending on the client's individual response and the presence of other medications. The client should follow the prescribed schedule given by the healthcare provider.

D) This choice is incorrect because monitoring blood pressure daily and adjusting the dose accordingly is not specific to the administration of spironolactone. While blood pressure may need to be monitored regularly, dosage adjustments should only be made under the guidance of the healthcare provider.
