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.)

Answer and Explanation

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"]

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 ["105"]

Explanation

To find the answer, we can use the following steps:

- Convert the infant's weight from grams to kilograms by dividing by 1000

- Multiply the weight in kilograms by the dosage in mg/kg/day

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (3,500) / (1000) = 3.5 kg

- (dose in mg/day) = (30) x (3.5) = 105 mg/day

- (rounded dose in mg/day) = 105 mg

Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.
