Calculation
A nurse is preparing to administer enoxaparin 5 mg/kg subcutaneous daily to a client who has deep-vein thrombosis. The client weighs 152 lb. Available is 120 mg/0.8 mL prefilled syringe. Calculate the dosage in mL that the nurse should administer. (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
mL
Explanation & Rationale
Convert client’s weight from ponds to kgs: 1 lb -> 0.453592 kg 152 lb -> ? Cross multiplying: 152 * 0.453592 = 68.945984 kg Calculate the total dose in mg: 5 mg -> 1 kg ? -> 68.945984 kg Cross multiplying: 68.945984 * 5 = 344.72992 mg Determine the volume of enoxaparin to administer: 120 mg -> 0.8 mL 344.72992 mg -> ? Cross multiplying: (344.72992 * 0.8) / 120 = 2.298199466666667 mL = 2.3 mL
