30
What vital sign is important to check before giving Nitro & why
BP because Nitro lowers BP. Hold Nitro is BP is <90/60
31
Preload
stretching of the muscle fibers in the ventricles
32
Afterload
Amount of pressure the left ventricle must work to pump blood into circulation
33
How does Nitro work?
it relaxes the walls of arteries & veins allowing them to dilate & improve oxygen flow
34
How does Nitro effect preload & afterload?
it lowers it
35
Nitro oral capsule or tablet & patch are used for prevention or occurring angina?
Prevention
36
Sublingual or oral spray is used for prevention or occurring angina?
occurring
37
Where do you put a Nitro patch?

43
What do Beta Blockers do to the body?
decrease: HR, BP, force of contraction, O2 consumption, afterload
44
"BETA BLOCKER" side effects
Bradycardia, Exacerbates heart failure, Tired, Appetite loss ; Bad dreams, Low state-depression, Only occasionally able to preform, Contractility decreased, knowledge deficit, Exacerbates asthma, Really nauseated
45
Can you stop beta Blockers abruptly? when should you hold med & call Dr?
No; if HR <60
46
Atenolol (Tenormin), Metoprolol (Toprol, Lopressor), Nadolol (Corgard) are examples of?
Beta Blockers
47
What people should not take beta blockers?
people with asthma, PVD, Sinus bradycardia
48
Calcium Channel Blockers do what to the body?
decreases preload & afterload, O2 consumption, BP, electrical excitation & contractility
49
What do Calcium Channel Blockers do to coronary arteries & peripheral arteries?
dilates them
50
Adverse effects of CCB
Abrupt N/V, bradycardia, Constipation, Dizziness, EDEMA, Falling sperm count (doesnt stop them from being able to perform but it stops them from having kids), Gingival Overgrowth

BR, no caffeine, O2, Stool softeners, avoid Valsalva maneuver (breathing out of nose) because it drops BP
59
What do you do between 24-48 hrs after a patient has had an MI?
gradual increase activity, no smoking, cardiac diet
60
How long before scar tissue starts to form after a heart attack?

63
Mevacor, Zocor, Pravachol, Lipitor, Lescol, Crestor are exmples of?
Statins
64
