List three common adverse effects of beta-blockers and monitoring steps you would take in clinic.

Explanation:
Beta-blockers blunt sympathetic signals to the heart and kidneys, which slows the heart rate, lowers blood pressure, and can reduce energy or exercise tolerance. The three common adverse effects you’ll see are bradycardia, hypotension, and fatigue. Bradycardia occurs because the heart rate is reduced; hypotension comes from decreased cardiac output and reduced renin-angiotensin activity; fatigue arises from lower cardiac reserve and less sympathetic support during activity. In clinic, you monitor by checking resting heart rate and blood pressure before giving a dose and at follow-up, and you watch for signs of poor perfusion or symptomatic bradycardia (such as dizziness, fainting, cool extremities, or reduced urine output). If the heart rate is too low or the blood pressure too low, you would withhold or adjust the dose and reassess. Other listed effects are not typical primary adverse effects of beta-blockers, and the monitoring described aligns with common clinical practice for these drugs.
