A nurse is conducting a community health education session on heart health. Which lifestyle factor should the nurse emphasize as a potential modifiable risk factor for congestive heart failure?

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.

A) This choice is incorrect because serum sodium levels are not directly impacted by digoxin. However, electrolyte imbalances, including hypokalemia, can potentiate digoxin toxicity, so potassium levels should be monitored.

B) This choice is incorrect because while digoxin can impact liver function, it is not the primary parameter to be monitored. Liver function tests may be performed periodically to assess liver health during digoxin therapy.

C) This choice is correct. Digoxin is a cardiac glycoside that can impact renal function. Monitoring urine output is essential to assess kidney function and the client's response to the medication.

D) This choice is incorrect because blood glucose levels are not specifically impacted by digoxin. However, hypokalemia resulting from digoxin therapy can cause alterations in glucose metabolism, so blood glucose levels should be monitored in clients taking digoxin.
