Pharmacology
Beta-Adrenergic Blockers
Beta-blockers manage hypertension and heart failure by blocking the effects of epinephrine, reducing heart rate and blood pressure.
Nursing Priorities
- Always check apical pulse and blood pressure before administration.
- Hold medication if heart rate is less than 60 bpm or systolic BP is less than 90-100 mmHg.
- Educate patient on slow position changes to prevent orthostatic hypotension.
- Monitor for bronchospasm, especially in patients with a history of asthma or COPD.
Patient Education
- Do not abruptly discontinue therapy to avoid rebound hypertension.
- Monitor daily weights and report weight gain of more than 2-3 lbs per day.
- Check blood glucose frequently if diabetic, as beta-blockers can mask hypoglycemia symptoms.
