used for HTN, MI. side effect - hypotension, so monitor BP!
Beta blockers (lol's) uses
used for angina, MI (standard of care for all post MI pts indefinitely), CHF (only stable, chronic - not early mgmt), tachyarrhythmias.
Beta blockers MOA
they inhibit/block the SNS response - decrease HR, contractility, stroke volume, CO, BP, AV node conduction
Beta blockers side effect
hypotension (don't give if SBP < 100), bradycardia, AV block, extreme fatigue/lethargy, impotence
Beta blockers nursing considerations
monitor BP & HR. contraindicated if HR < 60 bpm, insulin dependent DM (monitor sugar more often), asthma, PVD
Natrecor (natriuretic peptide) MOA and use
causes diuresis - opposes renin so it causes excretion of sodium & water to treat fluid overload. used for ACUTE episodes of CHF.
Natrecor (natriuretic peptide) side effect
hypotension - monitor BP, HR, rhythm closely. may need to reduce dosage.
Calcium channel blockers (Cardizem, Procardia/nifedipine, Norvasc/amlodipine) MOA and uses
slows ventricular rate. decreases afterload. more of an antiarrhythmic. Used for HTN, Afib, Aflutter.
angina, MI, HTN, CHF, shock. consider early admin. in select pts: suspected ischemic chest pain, UA (change in angina pattern), acute pulm. edema (if BP > 90 systolic).
decreases pain of ischemia, venous blood return to heart, preload & cardiac O2 consumption. Increases venous dilation and cardiac collateral flow. Dilates coronary arteries.
Nitro side effect
mainly hypotension (bc it's a dilator). Extreme caution if systolic BP < 90 and w/RV infarction, limit drop to 10% if pt normotensive, limit drop to 30% if pt hypertensive. Watch for HA, syncope, tachycardia.
brings BP down really quickly - monitor BP every minute! drug of choice for hypertensive crisis (malignant HTN)
Aspirin actions will reduce:
overall mortality from AMI, nonfatal reinfarction, nonfatal stroke. will not do anything to clot already there!
CHEW the tablet. standard therapy for new pain suggestive of AMI. better to use baby aspirin bc it's flavored. if allergic give plavix.
antiplatelet that PREVENTS clot formation, prevents platelet aggregation and vasoconstriction. used for CAD, post MI (STEMI and NSTEMI).
