The 3 main categories of antianginal drugs are ____
|
Nitrates-Nitrites / Calcium Channel Blockers / Beta Blockers
|
|
Headache, tachycardia, and postural hypotension are adverse effects of __________
|
Nitrites (Nitroglycerin)
|
|
If nitrate-induced vasodilation occurs too rapidly, the cardiovascular system overcompensates and increases heart rate, a condition called ___
|
Reflex Tachycardia
|
|
Topical _____ can produce various types of dermatitis, which is actually a reaction to the delivery method, not the drug
|
Nitrate dosage
|
|
This antiangina drug is also effective in treating hypertension, MI, and dysrhythmia
|
Beta Blockers
|
|
Explain angina
|
During exercise/stress the adrenergic receptors in the heart muscles receive more NE/E causing an increase in systole and decrease in diastole. Less time for refill means less oxygenated blood gets to heart arteries. Ischemic condition causes pain.
|
|
This drug also has the ability to supress the activity of the hormone, Renin (which causes vasoconstriction when kidneys need more blood pressure)
|
Beta Blockers
|
|
The most effective drug for exertional angina (caused by excercise), also used for migraines (in low dosages) and tachycardia (associated with stage fright)
|
Beta Blockers
|
|
Verapamil and Diltiazem are a common generic name for what class of drug (ending is different, so must remember)
|
Calcium Channel Blocker
|
|
Besides their anginal/hypertension application, these two classes of drug also decreases heart rate, and treat dysrhythmia.
|
Calcium Channel Blockers & Beta Blockers
|
|
This antianginal works by reducing venous return (preload) and reducing systemic vascular resistance (afterload) via dilation
|
Nitrates-Nitrites
|
|
This antianginal works by slowing the heart rate and decreasing contractiliyt, thereby decreasing oxygen demands
|
Beta Blockers
|
|
This antianginal works by decreases influx of calcium into the smooth muscle, causing vascular relaxation
|
Calcium Channel Blockers
|
|
Before administering antianginals, what should the nurse check? What should the reading be?
|
Apical Pulse for 1 minute / 60-100 beats/min
|
|
Why should an antianginal medication that lowers heartrate not be given to a patient whose heart rate is higher than 100?
|
Reflex Tachycardia can happen which will actually RAISE the rate higher
|
