Question 1 of 5
Administer a continuous Dopamine infusion at 3 mcg/kg/min. The drug is available as 600 mg in 1000 ml of fluid. The client's weight is 110 pounds. Calculate mcg/min, mcg/hr, and ml/hr. (Include unit of measure with each answer)
Correct Answer: 0.25
Rationale:
To calculate the mcg/min, first convert the weight from pounds to kg (110 lbs/2.2 = 50 kg).
Then, multiply 3 mcg/kg/min by the weight in kg (3 mcg/kg/min * 50 kg = 150 mcg/min). Next, to calculate mcg/hr, multiply mcg/min by 60 (150 mcg/min * 60 min = 9000 mcg/hr). Finally, to find ml/hr, divide the total dose (600 mg) by the concentration (1000 ml) to get mg/ml (600 mg/1000 ml = 0.6 mg/ml), then divide the mcg/hr by the mg/ml to get mcg/ml (9000 mcg/hr / 0.6 mg/ml = 15000 mcg/ml), and convert mcg/ml to ml/hr (15000 mcg/ml * 1 ml/1000 mcg = 15 ml/hr).
