-Be cautious with those with acute MI, incomplete heart block, and renal insufficiency, pregnancy, and elders
What is Nitrates (SL Nitroglycerine) used for? (Antianginal)
To cause venous and arteriole dilation of smooth muscle. The vasodilation allows for a decrease in preload –> reducing cardiac output and workload of the heart, which helps to lower the myocardial oxygen demand
What would you use a Short acting Nitrates (SL Nitroglycerine) for? (Antianginal)
acute angina
What would you use a long acting Nitrates for? (Antianginal)
Use a transdermal patch and extended release nitroglycerin ( ISOSORBIDE)
helpful in treating hypertension
side/ adverse affects of Nitrates (SL Nitroglycerine)? (Antianginal)
**remember the 3 H’s
Always check BP before giving this drug
What are nursing considerations when administering Nitrates (SL Nitroglycerin)? (Antianginal)
- Give in intervals of 3 doses - one spray SL, wait 5 min, second spray 5 min, third spray, if it does not subside by third spray - call 911.
- Check BP after each spray. Patient can develop tolerance to drug.
What do Beta- Adrenergic Blockers (-olol) do? (Antianginal)
Slows heart rate (negative chronotropic effect) and reduces contractility (negative inotropic effect)
What are Beta- Adrenergic Blockers (-olol) used for? (Antianginal)
To decrease frequency of angina attacks by exertion
What are the side/ adverse affects for Beta- Adrenergic Blockers (-olol)? (Antianginal)
What are the side/ adverse affects for Beta- Adrenergic Blockers (-olol)? (Antianginal)
-Fatigue during exercise because these drugs prevent HR increase.
- Postural hypotension
What are some nursing considerations when administering Beta- Adrenergic Blockers (-olol)? (Antianginal)
-Change positions slowly
-Do not discontinue abruptly
-Do not take OTC meds or herbal supplements without discussing with a health care provider.
-Monitor pulse - >50bpm.
-Alternate periods of exercise with periods of rest
What are calcium channel blockers used for? (Antianginal)
to relax arterial smooth muscle which lowers BP. –> Decreases afterload causing a decrease in myocardial oxygen demand
What do calcium channel blockers do? (Antianginal)
-Slows conduction velocity –> decreases HR and cardiac workload
-Dilates coronary arteries, more O2 to myocardium
What are the side/adverse affects of calcium channel blockers? (Antianginal)
-Constipation
-Fluid retention
What are some nursing considerations when administering calcium channel blockers? (Antianginal)
- Take BP on both arms while laying down
-Keep record of frequency and severity of each angina attack
-Change positions slowly
-Alert health care provider if shortness of breath, weight gain, and slow heartbeat appear - avoid grapefruit juice
*Do not crush or break XR tabs
What do Beta 1 Adrenergic Blockers do? (Anti-dysrhythmics)
- Block the effect of epinephrine and norepinephrine on the heart
- Decreases the ability of the SA node to fire spontaneously, decreasing conductivity
- Decreases cardiac contraction
What are the side/ adverse affects of Beta 1 Adrenergic Blockers?
(Anti-dysrhythmics)
bronchoconstriction
What do Potassium channel blockers do? (Anti-dysrhythmics)
-They block potassium channels !!
-cause vasodilation
-Delay the repolarization of the myocardial cells
What are the side/ adverse affects for potassium channel blockers?
(Anti dysrhythmics)
…
What are some nursing considerations when administering potassium channel blockers?
(Anti dysrhythmics)
correct hypokalemia prior to therapy
What do calcium channel blockers do?
(Anti dysrhythmics)
- stops the calcium influx across cardiac and smooth muscle
- Decreases excitability, conductivity, and contractility of the heart
What are the side/ adverse affects of calcium channel blockers?
(anti- dysrhythmics)
Bradycardia, heart failure, hypotension
What are some nursing considerations when administering calcium channel blockers?
