Question 1 of 5
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.)
Correct Answer: A
Rationale: 152 lb = 68.946 kg; 5 mg/kg × 68.946 = 344.73 mg; 344.73 mg ÷ (120 mg/0.8 mL) = 2.3 mL.
