Dobutamine 250 mg in 250 mL D5W is prescribed at 5 mcg/kg/min for a client who weighs 80 kg. At what rate in mL/hr should the nurse set the pump?
mL/hr
Show answer and rationale
Answer: 24 mL/hr
Concentration: 250 mg ÷ 250 mL = 1 mg/mL = 1,000 mcg/mL. Dose: 5 × 80 = 400 mcg/min × 60 = 24,000 mcg/hr. Rate: 24,000 ÷ 1,000 = 24 mL/hr.
