Question 1 of 5
Give Dobutamine 5.5 mcg/kg/min. The drug is available as 750 mg in 500 ml of fluid. The client weighs 220 pounds. Calculate mcg/min, mcg/hr, and ml/hr. (Include the unit of measure for each answer).
Correct Answer: 22
Rationale:
To calculate mcg/min: 5.5 mcg/kg/min * 220 lb * (1 kg/2.2 lb) = 1,100 mcg/min.
To convert mcg/hr: 1,100 mcg/min * 60 min/hr = 66,000 mcg/hr.
To find ml/hr: 750 mg / 500 ml = 1.5 mg/ml. 5.5 mcg/kg/min * 220 lb * (1 kg/2.2 lb) = 1,100 mcg/min. 1,100 mcg/min * 60 min/hr = 66,000 mcg/hr. 66,000 mcg/hr / 1,000 = 66 mg/hr. 66 mg/hr / 1.5 mg/ml = 44 ml/hr.
Therefore, the correct answer is 22 mcg/min, 66,000 mcg/hr, and 44 ml/hr. Other choices are
