A nurse is preparing to administer diphenhydramine 1.25 mg/kg IM to a child who weighs 68 lb. Available is diphenhydramine injection 50 mg/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 ["0.8"]
First, the child's weight needs to be converted from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
68 lb ÷ 2.2 = 30.9 kg
Next, the dose of diphenhydramine in mg can be calculated by multiplying the child's weight in kg by the dose in mg/kg.
1.25 mg/kg × 30.9 kg = 38.6 mg
Finally, to calculate the number of mL the nurse should administer, you need to divide the dose of diphenhydramine in mg by the concentration of the diphenhydramine injection in mg/mL.
38.6 mg ÷ 50 mg/mL = 0.8 mL
So, the nurse should administer 0.8 mL of diphenhydramine injection.

Correct Answer is ["0.9"]
Explanation
First, you need to convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram, so 99 lb / 2.2 = 45 kg. The dose of morphine is 0.2 mg/kg, so for a client who weighs 45 kg, the dose would be 0.2 mg/kg * 45 kg = 9 mg. To calculate the number of mL the nurse should administer, you need to divide the dose of morphine (9 mg) by the concentration of the morphine injection (10 mg/mL). This gives you 9 mg / (10 mg/mL) = 0.9 mL. When rounded to the nearest tenth, this remains
0.9 mL. So, the nurse should administer 0.9 mL of morphine injection.
Correct Answer is ["50"]
Explanation
If the daily dose is 200 mg and it is to be given in equally divided doses every 6 hours, then we need to
calculate the amount per dose:
200 mg ÷ 4 doses = 50 mg per dose
