    Calculate the flow rate I mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 25,000 units of Heparin in 250 mL to infuse at 11 mL/hr. Calculate rate in units/hr.

    Explanation & Rationale

    Given: Total Heparin in solution: 25,000 units Volume of solution: 250 mL Infusion rate: 11 mL/hr Step 1: Calculate the concentration of Heparin in the solution: Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL) Concentration (units/mL) = 25,000 units / 250 mL Concentration (units/mL) = 100 units/mL Step 2: Calculate the infusion rate in units/hr: Infusion rate (units/hr) = Infusion rate (mL/hr) x Concentration (units/mL) Infusion rate (units/hr) = 11 mL/hr x 100 units/mL Infusion rate (units/hr) = 1100 units/hr
