Study Notes
Angiotensin Converting Enzyme (ACE) Inhibitors
- Antihypertensive drugs that promote renal excretion of salt and water.
- Lower vascular resistance without increasing cardiac output, rate, or contractility.
- Generic names end with "-pril."
- Treat hypertension, congestive heart failure, and reduce the risk of stroke and heart attack.
- Desired outcomes include controlled blood pressure, improved survival rates for acute MI, and decreased cardiovascular workload.
- Common side effects: postural hypotension, fatigue, loss of appetite, nausea, vomiting, diarrhea, hyperkalemia, insomnia, exacerbation of cough, and angioedema.
Nursing Considerations for ACE Inhibitors
- Monitor electrolytes due to potassium retention.
- Elderly clients are at higher risk for postural hypotension.
- Avoid abrupt discontinuation to prevent rebound hypertension.
- Frequently monitor blood pressure.
- Use caution in clients with renal impairment.
- Notify physician if dizziness persists.
Angiotensin II Receptor Blockers (ARBs)
- Block the action of Angiotensin II, which narrows blood vessels and raises blood pressure.
- Generic names end with "-sartan."
- Indications include hypertension, congestive heart failure, kidney failure in diabetes, chronic kidney diseases, and scleroderma.
- Side effects: headache, dizziness, nasal congestion, vomiting, diarrhea, back and leg pain, hyperkalemia, and angioedema.
Nursing Considerations for ARBs
- Contraindicated for pregnant or breastfeeding women.
- Use cautiously with hypovolemia, hepatic, and renal dysfunction.
- Notify physicians for edema but do not discontinue without consulting a doctor.
- Advise clients to change positions slowly to prevent hypotension from fluid volume reduction.
Anti-Anginals
- Peripheral vasodilators that decrease cardiac workload, commonly ending in "-nitrate."
- Indicated for angina and controlling perioperative blood pressure.
- Side effects: headache, blurred vision, dry mouth, postural hypotension, syncope, and reflex tachycardia.
Nursing Considerations for Anti-Anginals
- Educate clients on the purpose of transdermal patches for chest pain management.
- Advise limiting alcohol to prevent exacerbating postural hypotension.
- Report severe side effects such as continuous headaches or blurred vision.
- Topical applications provide sustained protection against angina; avoid skin contact.
Anticoagulants
- Examples include IV heparin, SubQ enoxaparin, and oral warfarin.
- Indicated for thromboembolic disorders like DVT, pulmonary embolism, and atrial fibrillation with emboli.
- Key lab values: PT (10-14 seconds), aPTT (20-36 seconds), INR (2.0-3.0).
- Contraindications: coagulation disorders, recent surgery, cancer, and thrombocytopenia.
- Adverse effects include pain at the injection site, thrombocytopenia, and hemorrhage.
Nursing Responsibilities for Anticoagulants
- Avoid administering heparin via the intramuscular route.
- Do not aspirate or rub the injection site; rotate injection sites.
- Minimize venipunctures and apply pressure to puncture sites.
- Monitor diet for vitamin K intake as it can alter warfarin effects.
- Inform practitioners about anticoagulant use before medical procedures.
- Assess for bleeding; monitor hemoglobin, clotting time, and platelets.
Anti-Platelet Drugs
- Inhibit platelet aggregation to prevent thrombus formation.
- Indicated for cerebrovascular accidents, myocardial infarctions, rheumatic heart disease, pericarditis, pulmonary embolism, and DVT.
- Drug examples include aspirin, clopidogrel (Plavix), pentoxifylline (Trental), cilostazol (Pletal), and ticlopidine (Ticlid).
- Side effects: bruising, hematuria, gastrointestinal bleeding, and melena.
- Contraindications include peptic ulcers and bleeding disorders.
Diuretics
- Major types include loop, thiazide, potassium-sparing, and osmotic diuretics, leading to increased urine output and sodium loss.
- Commonly used to manage hypertension, edema, and heart failure.
- Side effects may include electrolyte imbalances (hypokalemia or hyperkalemia), dehydration, dizziness, and frequent urination.
