A nurse is preparing to administer risperidone 25 mg IM. After reading the label, how many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.67"]
To find out how many mL of risperidone the nurse should administer, we need to set up a proportion.
If 37.5 mg of risperidone is equivalent to 1 mL, then 25 mg of risperidone is equivalent to x mL. The proportion can be writen as 37.5/1 = 25/x. Solving for x, we get x = (25 * 1) / 37.5 = 0.67 mL. The answer is rounded to the nearest hundredth as instructed.

Correct Answer is ["1.2"]
Explanation
To calculate this, divide the dose of hydrocortisone in mg by the concentration of the reconstituted hydrocortisone to find the volume to administer: 60 mg / (50 mg/mL) = 1.2 mL.
Correct Answer is ["1.1"]
Explanation
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.
