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 ["1.6"]
Explanation
To calculate this, first convert the preschooler's weight from pounds to kilograms: 36 lb * (1 kg / 2.2 lb) = 16.36 kg.
Then, calculate the dose of furosemide in mg: 1 mg/kg * 16.36 kg = 16.36 mg.
Finally, divide the dose in mg by the concentration of the furosemide injection to find the volume to administer: 16.36 mg / (10 mg/mL) = 1.636 mL/dose, which rounds to 1.6 mL when rounded to the nearest tenth.
Correct Answer is ["500"]
Explanation
To calculate this, first convert the infusion time from minutes to hours: 15 min * (1 hr / 60 min) = 0.25 hr.
Then, divide the volume of the infusion by the infusion time to find the rate: 125 mL / 0.25 hr = 500 mL/hr.
