Q

Neosynepherine Side effects

A

reflex bradycardia because increase svr -> sensors in carotid/ aortic arch to decrease CO in response to the inc bp by increasing vagal tone

Q

hydralazine MOA

A

arterial vasodilator by decreasing IP3 decreases calcium release in smm

24
Q

A

rebound tachycardia

25
Q

Metoprolol dose

A

1-15 mg

26
Q

Metoprolol MOA

A

Selective Beta 1 antagonist

27
Q

Beta 1 selective antagonist side effects with DM pts

A

interferes w/ gluconeogeneissi and potentiates insulin

28
Q

Beta 1 selective blockers effects on K

40
Q

What medication is used to reverse catecholamine resistance

A

vasopressin

41
Q

Vasopressin MOA

A

ADH
V1>V2

V1 = increase water reabsoprtion

42
Q

Calcium chloride dose

A

250-1000 mg

43
Q

Calcium chloride MOA

A

inoppressor

increase ca concentration = increase gradient for ca to enter smm and cardiac cells = increase contraction / bp

44
Q

Dobutamine gtt dose

A

2-20 mcg/kg/min

45
Q

Dobutamine MOA

A

Selective beta 1 agonist

increase hr, increase co, decrease svr, decrease pvr

46
Q

A

1-20 mcg/ min

47
Q

Isoproterenol moa

A

Beta agonist

vasodilate coronary arteries

48
Q

A

25-50mcg/kg

49
Q

Milrinone gtt dose

A

0.125-0.75 mcg/kg/min

50
Q

Milrinone MOA
