Cardiac Meds

Question 1

ACE inhibitors

Answer 1

• inhibit conversion of angiotensin 1-2
• decreases Na+ retention and vasodilates to decrease BP
• Treats CHF, HTN

Question 2

ACE inhibitor alert for

Answer 2

-dizziness, lightheadedness

Question 3

ARB

Answer 3

• blocks binding of angiotensin 2 to smooth muscle
• decrease BP
• Treats HTNand CHF

Question 4

Nitrates

Answer 4

• decreases preload through peripheral vasodilation
• decreased myocardial O2 demand, dilates coronary arteries
• can cause headache

Question 5

Beta adrenergic blockers

Answer 5

• decreases mycardial demand by decreasing HR and contractility
• treats CHF, HTN, s/p HA/CABG

Question 6

Ca channel blockers

Answer 6

• inhibits flow of Ca ions, decreases HR/contractivity
• dilates coronary arteries, decreasing BP
• Afib, angina, HTN

Question 7

Digitalis

Answer 7

• increases contractility, decreases HR

- main treatment of CHF

Question 8

Diuretics

Answer 8

• decrease preload and afterload which reduces myocardial work
• Edema and HTN
• can cause hypokalemia

Question 9

Statins

Answer 9

• decrease cholesterol

- cause muscle weakness/pain
