A nurse is reviewing the diagnostic tests for a client suspected of having congestive heart failure. Which test is considered the gold standard for diagnosing CHF?

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.

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.
