Calculation
The healthcare provider prescribes the standard heparin protocol for a client who weighs 95 kg and is diagnosed with a deep vein thrombosis. The loading dose is an IV bolus of 80 units/kg. Heparin is available in vials of 5,000 units/mL. How many mL of heparin should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
mL
Explanation & Rationale
Given: Ordered loading dose of Heparin: 80 units/kg Patient weight: 95 kg Concentration of Heparin: 5,000 units/mL Step 1: Calculate the total loading dose of Heparin: Total loading dose (units) = Ordered dose (units/kg) x Patient weight (kg) Total loading dose (units) = 80 units/kg x 95 kg Total loading dose (units) = 7600 units Step 2: Calculate the volume to be administered: Volume (mL) = Total loading dose (units) / Concentration (units/mL) Volume (mL) = 7600 units / 5000 units/mL Volume (mL) = 1.52 mL Step 3: Round to the nearest tenth: Volume (mL) ≈ 1.5 mL
