Calculation
Heparin 5,000 units IV is prescribed as a loading dose, to be administered over 5 minutes for a client with thrombophlebitis. The vial is labeled, "10,000 units/mL." How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
mL
Explanation & Rationale
Calculation: Desired dose = 5,000 units. Available concentration = 10,000 units/mL. Calculate the volume to administer in milliliters (mL). Volume to administer (mL) = Desired dose (units) / Available concentration (units/mL) = 5,000 units / 10,000 units/mL = 0.5 mL.
