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 convert the client's weight from pounds to kilograms (176 lb / 2.2 = 80 kg). Then, calculate the total dose per minute (3 mcg/kg/min * 80 kg = 240 mcg/min). Next, calculate the total dose per hour (240 mcg/min * 60 min = 14,400 mcg/hr). Finally, determine the mL/hr by dividing the total dose per hour by the concentration of the drug (14,400 mcg/hr / 500 mg in 250 mL = 28.8 mL/hr). Therefore, the correct answer is 240 mcg/min, 14,400 mcg/hr, and 28.8 mL/hr. Other choices are incorrect as they do not follow the proper conversion and calculation steps.
