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 A
Explanation
To calculate the dose of brentuximab in mg that the client should receive, we need to multiply the weight of the client in kg by the prescribed dose of 1.8 mg/kg:.
Dose (in mg) = Weight (in kg) x Dose (in mg/kg).
Dose (in mg) = 60 kg x 1.8 mg/kg. Dose (in mg) = 108 mg.
Now we need to calculate the volume of medication to administer. Since the medication available is 50 mg per 10 mL, we can use proportion to calculate the volume:.
50 mg is to 10 mL as 108 mg is to X mL. 50/10 = 108/X.
Cross-multiplying, we get:. 50X = 108 x 10.
X = (108 x 10)/50. X = 21.6 mL.
Therefore, the nurse should administer 21.6 mL of brentuximab to the client.
Correct Answer is A
Explanation
To calculate the time it will take to finish the infusion, we can use the formula:
Time = Volume / Rate
Plugging in the given values, we get:
Time = 1.5 L / 75 mL/hr Converting 1.5 L to mL, we get:
Time = 1500 mL / 75 mL/hr Simplifying, we get:
Time = 20 hours
Therefore, it will take 20 hours to finish the infusion at the current rate.
