Question 2

Aldosterone antagonist
Potassium-sparing
Avoid renal patients who can’t excrete K

Answer 2

spironolactone (Aldactone)

Question 3

Ace inhibitor that reduces preload and after load
Decreases contractility
Increases perfusion
Inhibits RAS system
Blocks vasoconstriction 
S/E: cough

Answer 3

Enalapril (Vasotec)

Question 4

Angiotensin II receptor blocker (ARB)
Blocks vasoconstriction
Inhibits Na & H2o retention
Can be given with diuretic

Answer 4

losartan (Cozaar)

Question 5

Beta blocker
Directly blocks SNS; dcrses HR and contractility thereby decrsing cardiac output
Blocks fight or flight response

Answer 5

Propranolol (Inderal)

Question 6

Blocks the enzyme that converts angiotensin I (in lungs) to angiotensin II
This stops vasoconstriction and the release of aldosterone
