A client who weighs 60 kg receives a prescription for dalteparin 200 units/kg subcutaneously once a day for a month. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer? (Enter numerical value. If rounding is required, round to the nearest tenth.)
To administer dalteparin to a client who weighs 60 kg, the nurse should know how many mL to give once a day for a month. The prescription is for dalteparin 200 units/kg subcutaneously once a day for a month and it is available in a vial that contains 25,000 units/mL of dalteparin. To calculate the dose in units, multiply the weight in kg by the dose in units/kg. For example, 60 kg x 200 units/kg = 12 ,000 units. To calculate the volume in mL, divide the dose in units by the concentration in units/mL. For example, 12 ,000 units /25 ,000 units/mL = 0 .48 mL. If rounding is required, round to the nearest tenth. Therefore, the nurse should administer 0 .5 mL of dalteparin once a day for a month.
