A primary healthcare provider prescribes 25 mg per kilogram per dose of carmustine to a child with Hodgkin disease. A nurse finds that the child weighs 99 lbs. What dosage of medication should the nurse administer to the child daily?

1125 mg/dose

1237.5 mg/dose

2475 mg/dose

6544.5 mg/dose

Answer and Explanation

The Correct Answer is A

First, we need to convert the weight of the child from pounds to kilograms:. 99 lb / 2.2046 = 44.91 kg (rounded to two decimal places).

Next, we can calculate the dose of carmustine:. 25 mg/kg x 44.91 kg = 1,122.75 mg.

We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 1,122.75 mg seems reasonable for a child with Hodgkin disease..

Since the medication is prescribed daily, the nurse should administer the calculated dose of 1,122.75 mg of carmustine to the child every day.

Correct Answer is B

Explanation

We can use proportion to calculate the volume of Primaxin to administer:. 275 mg is to X mL as 500 mg is to 2 mL.

275/X = 500/2.

Cross-multiplying, we get:. 500X = 275 x 2.

X = (275 x 2)/500. X = 1.1 mL.

Therefore, the nurse should administer 1.1 mL of Primaxin to the patient, rounded to the nearest tenth.

A. 2 mL B. 3 mL C. 4 mL D. 5 mL

Correct Answer is C

Explanation

The ordered dose is 400 mcg, which is equal to 0.4 mg..

The medication is provided as 0.1 mg/mL, so to administer 0.4 mg, the nurse needs to give:.

0.4 mg ÷ 0.1 mg/mL = 4 mL.

Therefore, the nurse should administer 4 mL of atropine sulfate.
