Correct Answer is ["18"]
Explanation
To calculate the infusion rate, we'll follow these steps:
Convert patient weight to kilograms:
220 lbs ÷ 2.2 lbs/kg = 100 kg
Calculate desired heparin dose:
18 units/kg/hr × 100 kg = 1800 units/hr
Determine infusion rate in mL/hr:
(1800 units/hr) / (25000 units/250 mL) = 18 mL/hr
Correct Answer is ["1.7"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Convert patient weight to kilograms:
121 lbs ÷ 2.2 lbs/kg = 55 kg
Determine the total daily dosage:
2.5 mg/kg/day × 55 kg = 137.5 mg/day
Calculate the dosage per dose:
137.5mg/day ÷ 2 doses = 68.75 mg/dose
Determine the volume to be administered:
68.75 mg ÷ 40 mg/mL = 1.7 mL
