A nurse is preparing to administer enoxaparin 20 mg subcutaneously to a school-age child. The amount available is enoxaparin 30 mg/0.3 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.2"]

To find out how many mL of enoxaparin the nurse should administer, we need to set up a proportion. If 30 mg of enoxaparin is equivalent to 0.3 mL, then 20 mg of enoxaparin is equivalent to x mL.

The proportion can be writen as 30/0.3 = 20/x. Solving for x, we get x = (20 * 0.3) / 30 = 0.2 mL.

Correct Answer is ["133"]

Explanation

To calculate this, divide the volume of the infusion by the infusion time to find the rate: 800 mL / 6 hr =

133.33 mL/hr, which rounds to 133 mL/hr when rounded to the nearest whole number.

Correct Answer is ["4.2"]

Explanation

Step 1: Convert the preschooler’s weight from pounds to kilograms. 37 lbs ÷ 2.2 = 16.8181 kg (rounded to four decimal places)

Step 2: Calculate the total daily dose of cephalexin in mg. 50 mg/kg/day × 16.8181 kg = 840.905 mg/day (rounded to three decimal places)

Step 3: Determine the number of doses per day. 24 hours ÷ 6 hours = 4 doses/day

Step 4: Calculate the dose per administration. 840.905 mg/day ÷ 4 doses/day = 210.22625 mg/dose (rounded to five decimal places)

Step 5: Convert the dose from mg to mL using the available suspension concentration. 250 mg ÷ 5 mL = 50 mg/mL

Step 6: Calculate the volume to be administered per dose. 210.22625 mg ÷ 50 mg/mL = 4.204525 mL (rounded to six decimal places)

Step 7: Round the final answer to the nearest tenth. 4.204525 mL rounded to the nearest tenth = 4.2 mL

Therefore, the nurse should administer 4.2 mL per dose.
