Question 17 :
A 4-year-old is admitted with croup and receives a prescription for a single dose of dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: ["10 mg"]
To answer this question, we need to convert the weight from pounds to kilograms and use the formula:
Dose in mg = Weight in kg x Dosage in mg/kg
Plugging in the given values, we get:
Dose in mg = (35 / 2.2) x 0.6
Dose in mg = 15.909 x 0.6
Dose in mg = 9.545
Rounding to the nearest whole number, we get:
Dose in mg = 10
Therefore, the nurse should administer 10 mg of dexamethasone.
