The healthcare provider prescribes dalteparin 200 units/kg subcutaneously once day for a client who weighs 154 pounds. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Calculation: Convert the client's weight from pounds (lb) to kilograms (kg). The client's weight is 154 lb. Client weight (kg) = 154 lb/2.2 lb/kg = 70 kg. Calculate the total dose to be administered (units). The ordered dose is 200 units/kg. Total dose (units) = 200 units/kg×70 kg = 14,000 units. Calculate the volume to administer in milliliters (mL). Available concentration is 25,000 units/mL. Volume (mL) = Total dose (units)/Available concentration (units/mL) = 14,000 units/25,000 units/mL = 0.56 mL. Round the answer to the nearest tenth. = 0.6 mL.
