A client being treated for hypovolemic shock is prescribed a low dose of dopamine. Which outcome does the nurse anticipate for this client?
A) Stabilization of fluid loss
B) Increased cardiac output
C) Vasoconstriction and increased blood pressure
D) Urinary output of at least 30 mL/hour
Answer: D
At low doses, dopamine 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 when beta1-adrenergic receptors are stimulated. Vasoconstriction and increased blood pressure occur with high, not low, doses of dopamine when alpha-adrenergic receptors are stimulated. Dopamine does not prevent or stabilize fluid loss.
