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.)
The Correct Answer is ["10 "]
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in mg/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (35) / (2.2) = 15.909
- (dose in mg) = (0.6) x (15.909) = 9.545
- (rounded dose in mg) = 10
Therefore, the nurse should administer 10 mg of dexamethasone to the child.

Correct Answer is ["0.8 mL"]
Explanation
To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (20) / (125 / 5)
Simplifying, we get:
(mL to be administered) = (20) x (5 / 125)
(mL to be administered) = 0.8
Therefore, the nurse should administer 0.8 mL of phenytoin suspension to the child.
Correct Answer is ["2"]
Explanation
The correct answer is 2 ounces. To find the answer, we can use the following steps:
- Calculate the volume of magnesium hydroxide in mL by dividing the dose in mg by the concentration in mg/mL
- Convert the volume in mL to ounces by multiplying by 0.0338
- Round the result to the nearest whole number
Using these steps, we get:
- (volume in mL) = (4800) / (400) = 12 mL
- (volume in ounces) = (12) x (0.0338) = 0.4056 ounces
- (rounded volume in ounces) = 2 ounces
Therefore, the nurse should instruct the client to take 2 ounces of magnesium hydroxide Saline Laxative, USP with each dose.
