N250 CARDIAC MEDS EXAM QUESTIONS AND ANSWERS

WITH COMPLETE SOLUTIONS GRADED A++


Dobutamine Class & Action

Sympathomimetic Beta 1 agonist that causes reverse effects of beta blockers. It ↑

contractility and causes tachycardia.

Dopamine Class & Action

adrenergic agonist vasopressor. Small doses ↑ renal perfusion. Higher doses cause

vasoconstriction. Also an inotropic via beta 1 stimulation at larger doses.

- S/E: tachycardia

Dopamine Indications

Shock

Dobutamine Indications

Cardiogenic shock, CHF

Nitroglycerin Class & Action

Nitration/vasodilator that causes ↑ vasodilation → ↓ preload. Also ↓ myocardial O2

demand. Will lower BP.

Nitroglycerin Indications

HF, acute MI, angina

Nitroprusside Class & Action

Vasodilator, requires constant monitoring of BP.

Nitroprusside Indications

, HTN Crisis, Cardiogenic shock

Norepinephrine Class & Action

Sympathomimetic, vasopressor.

- Vasoconstriction and myocardial stimulation.

- First-line vasoactive drug.

Norepinephrine Indications

Severe hypotension & shock

Epinephrine Class & Action

Catecholamine, sympathomimetic.

↑ BP w vasoconstriction and myocardial contractility.

S/E: tachycardia

Epinephrine Indications

- Hypotension caused by shock

- ACLS/PALS

- Severe allergic reactions (IM only)

Milrinone Class & Action

Inotropic, vasodilator

Inotropic effect. Vasodilates to reduce afterload. Watch for hypotension!

Milrinone Indications

Short-term treatment of HF unresponsive to conventional therapy with digoxin, diuretics,

and vasodilators. May be used in acute HF.

Vasopressin Class & Action
