Question 1 of 5
Administer Dopamine 3 mcg/kg/min. The client weighs 176 pounds. The drug is available as 500 mg in 250 mL of fluid. Calculate mcg/min, mcg/hr, and mL/hr. (Do not round your answer and include unit of measure with each answer)
Correct Answer: 7.2
Rationale:
To calculate the correct answer, first determine the client's weight in kilograms (176 lbs ÷ 2.2 = 80 kg).
Then, calculate the total mcg/min (3 mcg/kg/min × 80 kg = 240 mcg/min). Next, calculate mcg/hr (240 mcg/min × 60 min = 14,400 mcg/hr). Finally, determine mL/hr by converting mcg to mg (14,400 mcg ÷ 1000 = 14.4 mg/hr) and then to mL (14.4 mg/hr ÷ 500 mg/250 mL = 28.8 mL/hr).
Therefore, the correct answer is 7.2 because it accurately represents the mL/hr value. Other choices are incorrect due to miscalculations or unit errors.
