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:
To calculate the dosage in mL for enoxaparin, we first need to convert the client's weight from pounds to kilograms. 152 lb is approximately 69 kg (1 kg = 2.2 lb).
Then, we multiply the weight (69 kg) by the prescribed dose (5 mg/kg) to get the total dose required per day. This results in 345 mg/day. Since the prefilled syringe is 120 mg/0.8 mL, we divide the total dose required (345 mg) by the amount in one syringe (120 mg) to get the number of syringes needed. This equates to 2.875 syringes, which we can round to 2.9 syringes. Finally, to find the dosage in mL, we multiply the number of syringes (2.9) by the volume in each syringe (0.8 mL), which equals 2.32 mL. Rounding to the nearest
