Calculate the initial rate for a Heparin infusion. The infusion is ordered as 18 units/kg/hr. The client weighs 90 kg. The concentration of the Heparin bag is 25,000 units/250 mL. You are administering the Heparin drip via an electronic infusion device. Calculate the infusion rate in mL/hr.

Step 1: Calculate the total units to be given per hour: 18 × 90 = 1620 units/hour Result = 1620 units/hour Step 2: Determine the concentration of Heparin in 1 mL: 25000 ÷ 250 = 100 units/mL Result = 100 units/mL Step 3: Calculate the required volume in mL/hr using total units per hour: (1620 ÷ 100) = 16.2 mL/hr Result = 16.2 mL/hr Final answer 16.2 mL/hr Question 47 Calculate the initial bolus of Heparin. Heparin is ordered as 80 units/kg. The client weighs 90 kg. How many mL would you administer using a vial of Heparin labeled Heparin 5000 units/mL? The correct answer is 1.44 mL Explanation: Step 1: Calculate the total number of units required for the bolus: 80 × 90 = 7200 units Result = 7200 units Step 2: Use the vial concentration to find out how many mL deliver 7200 units: (7200 ÷ 5000) = 1.44 mL Result = 1.44 mL Final answer 1.44 mL
