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.
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 hypernatremia (high sodium levels) is not a common adverse effect of loop diuretics. Loop diuretics primarily impact sodium and water excretion.
B) This choice is incorrect because hyperkalemia (high potassium levels) is not typically associated with loop diuretics. In fact, loop diuretics can lead to increased potassium excretion, potentially causing hypokalemia.
C) This choice is incorrect because hypocalcemia (low calcium levels) is not a common adverse effect of loop diuretics. Loop diuretics primarily affect sodium, potassium, and water excretion.
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.
Correct Answer is C
Explanation
A) This choice is incorrect because an electrocardiogram (ECG) is a valuable diagnostic tool for assessing the heart's electrical activity and rhythm, but it is not the gold standard for diagnosing CHF. It can provide information about possible cardiac hypertrophy or rhythm disturbances associated with heart failure.
B) This choice is incorrect because a chest X-ray is helpful in evaluating heart size and the presence of pulmonary congestion, but it is not the gold standard for diagnosing CHF.
C) This choice is correct. An echocardiogram is the gold standard for diagnosing CHF. It uses ultrasound waves to assess the heart's structure and function, including ejection fraction and valve function, providing critical information to confirm the diagnosis of heart failure.
D) This choice is incorrect because a brain natriuretic peptide (BNP) level is a blood test that can aid in the diagnosis of CHF. Elevated BNP levels indicate heart strain, but it is not the gold standard for diagnosing CHF.
