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 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.

A. 0.14 mL B. 0.136 mL C. 136 mL D. 300 mL

Correct Answer is B

Explanation

To calculate the dose of digoxin in micrograms (mcg) that the child should receive, we need to first convert the weight of the child from pounds to kilograms:.

30 lb / 2.205 = 13.61 kg.

Next, we can calculate the dose of digoxin in mcg:. Dose (in mcg) = Weight (in kg) x Dose (in mcg/kg). Dose (in mcg) = 13.61 kg x 10 mcg/kg.

Dose (in mcg) = 136.1 mcg.

Now we need to calculate the volume of digoxin solution to administer. Since the concentration of the digoxin solution is 1 mg/mL, we can use proportion to calculate the volume:.

1 mg is to 1 mL as 136.1 mcg is to X mL. 1/1 = 136.1/X.

Cross-multiplying, we get:. 1X = 136.1 x 1.

X = 136.1 mL.

Therefore, the nurse should administer 0.1361 mL (136.1 mcg) of digoxin to the child.
