Dobutamine is often used in the treatment of sepsis at a moderate or high dose to improve a patient's hemodynamics. The nurse knows that this medication is used because:
1. It decreases systemic vascular resistance and increases perfusion to organs.
2. It has no effect on systemic vascular resistance but improves oxygenation.
3. It decreases the heart rate and increases oxygen delivery to the tissues.
4. It increases systemic vascular resistance and improves hemodynamics.

Rationale 1: Dobutamine is an inotrope that has beta-adrenergic effects. The expected outcome is to increase contractility and to vasodilate, which increases microcirculation or blood flow and organ perfusion.
Rationale 2: Vasodilatation decreases systemic vascular resistance.
Rationale 3: A side effect of dobutamine infusion is sinus tachycardia.
Rationale 4: Dobutamine decreases systemic vascular resistance.
