A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously every 12 hr.

The client's weight is 121 lb.

Available is enoxaparin 60 mg/0.6 mL.

How many mL should the nurse administer per dose? (Round the answer to the nearest tenth.

Use a leading zero if it applies. Do not use a trailing zero.)

0.5 mL.

0.600 mL.

0.6 mL.

0.8 mL.

Answer and Explanation

The Correct Answer is C

First, convert the client’s weight from pounds to kilograms: 121 lb /.2 = 55 kg. Then, calculate the dose in mg: 1 mg/kg * 55 kg = 55 mg.

Finally, use the ratio of available enoxaparin to calculate the volume to administer: (55 mg / 60 mg) * 0.6 mL = 0.55 mL.

Rounded to the nearest tenth, this is 0.6 mL.

Choice A is wrong because it is less than the calculated dose of 0.6 mL.

Choice B is wrong because it is equal to the calculated dose of 0.6 mL but not rounded to the nearest tenth.

Choice D is wrong because it is greater than the calculated dose of 0.6 mL.
