Question

Quizplus · Accepted Answer

Furosemide is a loop diuretic that promotes diuresis and decreases blood volume, which in turn decreases stroke volume. Dobutamine and dopamine are both positive inotropes that increase contractility and therefore increase stroke volume. Digoxin is a cardiac glycoside that also increases contractility and can have a positive inotropic effect on the heart, ultimately increasing stroke volume.
