Digoxin and furosemide were prescribed for a client with chronic heart failure, and the home health nurse is evaluating the client's self-care knowledge of these drugs. Which statement indicates that the client has a good understanding about the use of these drugs?

A. "I need to notify my healthcare provider if I lose my appetite or get nauseated." This statement shows understanding because loss of appetite and nausea can be symptoms of digoxin toxicity or side effects, and it is important to report these symptoms to a healthcare provider. Monitoring for such side effects is crucial when taking digoxin. B. "I should take my furosemide only if I have shortness of breath or swelling in my feet." This statement is incorrect because furosemide, a diuretic, should be taken according to the prescribed schedule, not based on symptoms. It is used to manage fluid retention and symptoms of heart failure, and its use should not be dependent solely on the presence of symptoms. C. "I need to check my blood pressure three times a day." While monitoring blood pressure is important, it is not specifically required for patients on digoxin and furosemide unless instructed by a healthcare provider. The focus should be more on monitoring for symptoms of drug side effects and electrolyte imbalances. D. "If I lose more than one pound in a week, I should hold my next dose of furosemide." Weight loss can be a normal effect of furosemide due to fluid loss, and the decision to hold a dose should be based on specific medical advice and not solely on weight change.
