A nurse is preparing to administer methimazole 0.3 mg/kg/day PO divided in equal doses every 8 hours to a school-age child who weighs 55 kg. Available is methimazole 5 mg tablets. How many tablets 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.)
The Correct Answer is ["1.1"]
First, we need to calculate the total daily dose of methimazole for the child.
The child weighs 55 kg and the prescribed dose is 0.3 mg/kg/day, so the total daily dose is 55 kg * 0.3 mg/kg/day = 16.5 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: 16.5 mg/day / 3 = 5.5 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: 5.5 mg per dose / 5 mg per tablet = 1.1 tablets per dose.

Correct Answer is ["400 mL\/hr"]
Explanation
To find out how many mL/hr the IV pump should be set to deliver, we need to convert the infusion time
from minutes to hours.
Since there are 60 minutes in an hour, 15 minutes is equivalent to 15/60 = 0.25 hours.
If 100 mL of 0.9% sodium chloride is to be infused over 0.25 hours, then the rate of infusion is 100/0.25 = 400 mL/hr. The answer is rounded to the nearest whole number as instructed.
Correct Answer is ["2 tablets"]
Explanation
To find out how many tablets of prednisone the nurse should administer, we need to convert the prescribed dose from grams to milligrams.
There are 1000 milligrams in 1 gram. Therefore, to convert 0.04 g to mg, we multiply 0.04 by 1000.
This gives us 40 mg. Since each tablet contains 20 mg of prednisone, the nurse should administer 40/20 = 2
tablets. The answer is rounded to the nearest whole number as instructed.
