Give Nitroprusside 0.5 mcg/kg/min. The client weighs 176 lbs. The drug is available as 500mg in 500 mL of fluid. Calculate mcg/min, mcg/hr, and mL/hr. (Round your answer to the nearest tenth and include the units of measure.)
The Correct Answer is ["2.4"]
Rationale:
To calculate the dosage of Nitroprusside in mcg/min, first convert the client's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. Therefore, 176 lbs is approximately 80 kg. Next, multiply the client's weight in kg by the dosage rate: 0.5 mcg/kg/min. So, 80 kg * 0.5 mcg/kg/min equals 40 mcg/min. To find mcg/hr, multiply the mcg/min dosage by 60, the number of minutes in an hour, which gives us 2400 mcg/hr. Finally, to calculate mL/hr, use the concentration of the drug: 500 mg in 500 mL. Since 1 mg equals 1000 mcg, 500 mg is 500,000 mcg. Divide the hourly dosage in mcg by the total number of mcg in the available fluid to find the mL/hr. Thus, 2400 mcg/hr divided by (500,000 mcg / 500 mL) results in 2.4 mL/hr. Rounded to the nearest tenth, the final dosages are 40 mcg/min, 2400 mcg/hr, and 2.4 mL/hr.
