A nurse is preparing to administer acetaminophen 10 mg/kg PO every 4 to 6 hours PRN pain to a toddler who weighs 26.4 lb. Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["3.8"]
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

Correct Answer is ["0.9"]
Explanation
To find out how many mL of gentamicin the nurse should administer, we need to set up a proportion. If 40 mg of gentamicin is equivalent to 1 mL, then 36 mg of gentamicin is equivalent to x mL.
The proportion can be writen as 40/1 = 36/x. Solving for x, we get x = (36 * 1) / 40 = 0.9 mL.
The answer is rounded to the nearest tenth as instructed.
Correct Answer is ["0.5"]
Explanation
Here's the detailed explanation: First, we need to convert the child's weight from pounds (lb) to kilograms (kg) since
the prescribed dose is in mg/kg/day.
There are approximately 2.2 lb in 1 kg, so the child's weight in kg is 55 lb / 2.2 = 25 kg. Next, we need to calculate the total daily dose of methimazole for the child.
The prescribed dose is 0.3 mg/kg/day, so the total daily dose is 25 kg * 0.3 mg/kg/day = 7.5 mg/day.
Since the medication is to be divided into equal doses every 8 hours, we need to divide the total daily dose by 3 to get the dose per administration: 7.5 mg/day / 3 = 2.5 mg per dose.
Finally, since each tablet contains 5 mg of methimazole, we need to divide the dose per administration by the amount of medication per tablet: 2.5 mg per dose / 5 mg per tablet = 0.5 tablets per dose.
