Study Notes
Foods High in Nutrients
- High potassium foods include bananas, cantaloupe, carrots, spinach, baked potatoes, oranges, and beets.
- Fiber-rich foods consist of lentils, oats, avocados, legumes, and beans.
- Healthy fats are primarily found in salmon and avocados.
Diets
- A cardiac diet emphasizes low fat, low sodium, and low cholesterol intake.
- The DASH diet is designed for hypertension management:
- High in potassium, calcium, and magnesium.
- Low in sodium.
- Includes grains, lean proteins (like salmon), legumes, nuts, seeds, low-fat dairy, and fresh fruits and vegetables.
Omega-3 Fatty Acids
- Known to help reduce blood clot formation, contributing to cardiovascular health.
Cardiovascular Medications
-
Nitroglycerin:
- Mechanism: Opens blood vessels, providing relief or prevention of angina, increasing cardiac output, and reducing blood pressure.
- Vital signs: Monitor BP and HR before and after administration; continuous BP monitoring required for IV use.
- Labs: Monitor INR.
- Nursing: Hold if BP drops below 90 systolic; monitor HR and BP every 5-15 minutes.
- Side effects include hypotension, tachycardia, syncope, and dizziness.
-
Digoxin (Lanoxin):
- Mechanism: Increases myocardial contraction force, prolongs AV node refractory period, decreases conduction through SA and AV nodes.
- Vital signs: Hold if HR is less than 60 bpm.
- Labs: Therapeutic range is 0.5-2 ng/mL.
- Nursing: Monitor apical pulse for a full minute; check at 5th intercostal space mid-clavicular line.
- Side effects include bradycardia, blurred vision, and GI upset. Signs of toxicity include yellow-green visual changes.
Anticoagulants (Blood Thinners)
- Common options include aspirin, warfarin, and apixaban.
- Mechanism: Slows the clotting process.
- Monitoring: BP, HR, and bleeding signs are essential.
- Labs: Monitor PT and APTT; hold if outside therapeutic range and monitor INR.
- Nursing interventions: Avoid activities that increase injury risk, educate on safe grooming practices.
- Side effects include dizziness, bleeding, and stomach upset.
ACE Inhibitors (suffix -pril)
- Popular names include enalapril, lisinopril, and ramipril.
- Mechanism: Primarily used to treat hypertension, lowering BP.
- Monitoring: Frequent BP and HR checks; watch for increased BUN and creatinine levels.
- Nursing considerations: Use cautiously in renal impairment; assess for signs of angioedema, which includes abdominal cramping and shortness of breath.
Beta Blockers (suffix -lol)
- Common drugs include atenolol, metoprolol, and labetalol.
- Mechanism: Decrease BP and HR; reduce frequency/severity of angina; control arrhythmias.
- Contraindicated for asthmatic patients.
- Monitoring: Track BP, ECG, pulse, and daily weights.
- Side effects include bradycardia, hypotension, fatigue, and respiratory issues.
