Rn Hesi Dosage Calculations ( 32 Questions)
The healthcare provider prescribes dopamine 2 mcg/kg/min intravenously (IV) for a client who weighs 132 pounds. The IV bag contains dopamine 45 mg in dextrose 5% in water (D5W) 500 mL. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 132 pounds is equivalent to 59.928 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 59.928 kg x 500 mL / 45000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 132.84 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 133 mL/h
