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
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 D
Explanation
The toddler is ordered to receive 25 mg/kg of Principen IV over 30 minutes. The toddler weighs 22 lb, which is equivalent to 10 kg. To calculate the total amount of Principen the toddler should receive, multiply the weight by the dosage:
10 kg x 25 mg/kg = 250 mg
The Principen dose arrives from the pharmacy prepared in 50 mL of IV solution, which means there is 250 mg of Principen in 50 mL of solution. To calculate how many milliliters per hour the nurse should administer, we can use the following formula:
50 mL / 0.5 hour = X mL per hour X = 100 mL per hour
Therefore, the nurse should administer 100 mL of Principen per hour to the toddler.
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.
