A nurse provided education to a client newly prescribed a beta-blocker. Which client statement indicates further education is needed?

A. I will monitor my heart rate regularly: Beta-blockers reduce heart rate by blocking beta-1 adrenergic receptors in the heart. Regular monitoring helps the client detect bradycardia and recognize when to hold the medication or notify the healthcare provider. B. I will eat a diet that is low-potassium: Beta-blockers do not significantly affect potassium levels in most clients. Dietary potassium restriction is more relevant for medications such as ACE inhibitors or potassium-sparing diuretics, this statement indicate misunderstanding. C. I will continue the medication if I get sick: Beta-blockers should not be stopped abruptly, even during illness, due to the risk of rebound hypertension or tachycardia. Continuing the medication unless instructed otherwise reflects appropriate understanding. D. Beta-blockers may cause me to feel dizzy: Dizziness can occur due to decreased blood pressure and reduced cardiac output, especially when starting therapy or changing positions. Awareness of this effect supports safe medication use and fall prevention.
