Use the low-dose range of 0.5-2 mcg/kg/min to determine the appropriate dose range of dopamine that would result in vasodilation and increased renal blood flow for a patient who weighs 132 pounds.

At low doses (0.5-2.0 mcg/kg/minute), dopamine stimulates dopaminergic receptors in renal and mesenteric blood vessels, resulting in vasodilation and increased renal blood flow. Step 1: Convert weight in pounds to kilograms. 1 kg:2.2 lb = X:132 lb. X = 132 lb/2.2 lb per kg = 60 kg. Step 2: Determine how many micrograms per minute of drug are required for the low and high ends of the range. Low: 0.5 mcg/kg/min F1F1F1S1F1F1F10 60 kg = 30 mcg/min. High: 2 mcg/kg/min F1F1F1S1F1F1F10 60 kg = 120 mcg/min. Step 3: Convert micrograms per minute to micrograms per hour. Low: 30 mcg/min F1F1F1S1F1F1F10 60 min/hr = 1800 mcg/hr. High: 120 mcg/min F1F1F1S1F1F1F10 60 min/hr = 7200 mcg/hr. Step 4: Convert micrograms per hour to milligrams per hour. Low: 1800 mcg/hr / 1000 = 1.8 mg/hr. High: 7200 mcg/hr / 1000 = 7.2 mg/hr.
