Why is it important for patients on beta-blockers to monitor their symptoms?

• A. To prevent weight gain
• B. To assess liver function
• C. To watch for bradycardia and fatigue
• D. To confirm drug efficacy

Answer: (C)

Patients on beta-blockers need to monitor their symptoms primarily to watch for bradycardia and fatigue. Beta-blockers work by blocking the effects of adrenaline on the heart, which slows the heart rate and helps reduce blood pressure. While this can be beneficial in managing conditions like hypertension and angina, it can also lead to an excessively low heart rate (bradycardia) in some patients. Fatigue is another common side effect due to the decreased cardiac output and the reduced heart rate. By monitoring their symptoms, patients can identify these adverse effects early, allowing for timely adjustments to their medication regimen. This is crucial because if bradycardia becomes severe, it can lead to significant health complications, including dizziness, fainting, or even heart failure. In contrast, options related to weight gain, liver function, or confirming drug efficacy are not directly linked to the primary concerns associated with beta-blocker therapy. While they may be relevant in different contexts, they do not emphasize the importance of symptom monitoring in relation to the specific side effects associated with beta-blockers.
