Correct Answer is ["0.8"]

Explanation

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 ["0.5"]

Explanation

To calculate the number of tablets to be administered, the nurse should divide the prescribed dose (20 mg) by the strength of the available medication (40 mg/tablet): 20 mg / 40 mg/tablet = 0.5 tablets.
