Correct Answer: 3
Rationale: At low doses, dopamine (Inotropin) stimulates dopaminergic receptors, especially in the kidneys, leading to vasodilation and an increased blood flow through the kidneys. Increased cardiac output occurs with high, not low, doses of dopamine (Inotropin) when beta1-adrenergic receptors are stimulated. Vasoconstriction and increased blood pressure occurs with high, not low, doses of dopamine (Inotropin) when alpha-adrenergic receptors are stimulated. Dopamine (Inotropin) does not prevent or stabilize fluid loss.
