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.)
The Correct Answer is ["0.2 mL"]
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 ["1.2"]
Explanation
To calculate this, first convert the adolescent's weight from pounds to kilograms: 96.8 lb * (1 kg / 2.2 lb) =
44 kg.
Then, calculate the dose of ketorolac in mg: 0.4 mg/kg * 44 kg = 17.6 mg.
Finally, divide the dose in mg by the concentration of the ketorolac to find the volume to administer: 17.6 mg / (15 mg/mL) = 1.173 mL, which rounds to 1.2mL when rounded to the nearest tenth.
Correct Answer is ["3.8"]
Explanation
To calculate the correct dose of acetaminophen for the toddler, follow these steps:
-
Convert pounds to kilograms:
- 26.4 lb * (1 kg / 2.2 lb) = 12 kg
-
Calculate the dose in mg:
- 12 kg * 10 mg/kg = 120 mg
-
Determine the volume to administer:
- 120 mg / 160 mg/5 mL = 3.75 mL
Therefore, the nurse should administer 3.8 mL of acetaminophen per dose.
answer = 3.8
