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.)

Answer and Explanation

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 A

Explanation

The nurse should identify **Kilogram** as a metric unit. The other units listed - Pound, Minim, and Ounce - are not metric units.

Correct Answer is ["3.5"]

Explanation

First, we need to convert the child's weight from pounds to kilograms.

Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =

23.587 kilograms.

The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.

Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.

Since the medication is to be administered once daily, the nurse should administer 3.538 mL per dose. Answer: 3.5
