A nurse is providing education to a client diagnosed with congestive heart failure. The client asks, "What are the most common causes of CHF?" How should the nurse respond?

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.

A) This choice is incorrect because clubbing refers to the enlargement of the fingertips and nails due to chronic hypoxia, which is not related to the client's reported symptoms.

B) This choice is correct. Peripheral edema refers to swelling in the legs, ankles, and feet, which is a common symptom of congestive heart failure. The client's symptoms of swollen ankles, legs, and abdomen indicate peripheral edema.

C) This choice is incorrect because pitting edema is a specific type of edema where pressure on the skin leaves an indentation or "pit." While the client's edema may indeed be pitting, the question does not provide enough information to confirm this.

D) This choice is incorrect because ascites is the accumulation of fluid in the abdominal cavity and is not specific to the client's reported symptoms of swollen ankles and legs.
