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 ["0.5 mL"]

Explanation

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

- Calculate the dose of dalteparin in units by multiplying the weight in kg by the dosage in units/kg

- Divide the dose in units by the concentration in units/mL

- Round the result to the nearest tenth

Using these steps, we get:

- (dose in units) = (60) x (200) = 12,000 units

- (volume in mL) = (12,000) / (25,000) = 0.48 mL

- (rounded volume in mL) = 0.5 mL

Therefore, the nurse should administer 0.5 mL of dalteparin from the vial to the client.

Correct Answer is ["270"]

Explanation

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

(remaining volume) = (initial volume) - (infused volume)

Substituting the given values, we get:

(remaining volume) = (440) - ((85 x 2))

Simplifying, we get:

(remaining volume) = (440) - (170)

(remaining volume) = 270

Therefore, the remaining volume to be infused is 270 mL.
