A nurse is caring for a client with suspected congestive heart failure. Which blood test is specifically used to measure heart strain and assist in the diagnosis of CHF?

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 hypokalemia (low potassium levels) is more commonly associated with loop diuretics rather than beta-blockers.

B) This choice is incorrect because while hypotension (low blood pressure) can be a potential adverse effect of beta-blockers, it is not the primary adverse effect to be monitored for.

C) This choice is correct. Bradycardia (slow heart rate) is a common adverse effect of beta-blockers, which work by slowing the heart rate and reducing the force of the heart's contractions. The nurse should monitor the client's heart rate and report any significant changes or symptoms of bradycardia to the healthcare provider.

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