A client with deep vein thrombosis (DVT) is receiving a continuous IV infusion of heparin sodium 20,000 units in 5% dextrose injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)
Explanation & Rationale
Here's how to calculate the total heparin units the client will receive in 12 hours Heparin concentration: The medication is delivered in a 500 mL bag containing 20,000 units of heparin. Heparin concentration (units/mL) = Total heparin (units) / Volume (mL) Heparin concentration (units/mL) = 20,000 units / 500 mL Heparin concentration (units/mL) = 40 units/mL Infusion rate: 25 mL/hour (given) Time: 12 hours (given) We need to find the total number of heparin units delivered in 12 hours. Total volume delivered in 12 hours: Volume delivered (mL/hour) x Time (hours) = Total volume delivered (mL) 25 mL/hour x 12 hours = 300 mL Total heparin units delivered: Heparin concentration (units/mL) x Total volume delivered (mL) = Total heparin units 40 units/mL x 300 mL = 12,000 units Therefore, the client will receive 12,000 units of heparin in 12 hours.
