Study Notes
Cardiac Medications Overview
- Cardiology involves a variety of medications targeting cardiac conditions and promoting cardiovascular health.
- Understanding different classes of cardiac drugs is essential for effective nursing practice.
Cardiotonics (Cardiac Glycosides)
- Regulate heart contractions; digoxin (Lanoxin) is the most notable example.
- Have a narrow therapeutic index; careful monitoring is necessary.
- Nursing considerations:
- Monitor heart rate and rhythm for one full minute; withhold administration if heart rate is below 60 beats per minute and notify a physician.
- Watch for signs of toxicity: symptoms include anorexia, nausea, vomiting, blurred vision, yellow-green vision, and dysrhythmias.
- Maintain electrolyte balance, particularly potassium levels, as low potassium increases the risk of digoxin toxicity.
- Educate patients about adhering to prescribed medication, monitoring pulse, and reporting adverse effects to their healthcare provider.
Anti-dysrhythmic/Anti-arrhythmic Drugs
- Used for treating cardiac rhythm abnormalities like atrial fibrillation and ventricular tachycardia.
- Nursing considerations:
- Closely monitor heart rate and rhythm due to the drugs’ effects on cardiac conduction.
- Assess for bradycardia or hypotension, especially with beta-blockers; withhold medication for low rates or pressures.
- Instruct patients on the importance of consistent medication adherence to prevent arrhythmia recurrence.
- Be aware of potential drug-drug interactions, especially with medications like amiodarone, which may increase adverse effects risk.
- Educate patients on monitoring heart status and avoiding exacerbating substances (alcohol, caffeine).
Anti-anginal Drugs
- Used to relieve chest pain due to inadequate oxygen supply to the heart.
- Includes organic nitrates, calcium channel blockers, and beta-blockers.
- Nursing considerations continue to focus on patient education, monitoring for effectiveness, and managing potential side effects.
