Penicillin G procaine 240,000 units intramuscularly is prescribed for a 4-year-old child who has a streptococcal respiratory infection. The medication vial is labeled 1,200,000 units/2 mL. How many mL should the nurse administer?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.4"]

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

(mL to be administered) = (units prescribed) / (units per mL)

Substituting the given values, we get:

(mL to be administered) = (240,000) / (1,200,000 / 2)

Simplifying, we get:

(mL to be administered) = (240,000 x 2) / (1,200,000)

(mL to be administered) = 480,000 / 1,200,000

(mL to be administered) = 0.4

Therefore, the nurse should administer 0.4 mL of penicillin G procaine to the child.

Correct Answer is ["168"]

Explanation

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

- Convert the client'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) = (185) / (2.2) = 84.091 kg

- (dose in mg) = (2) x (84.091) = 168.182 mg

- (rounded dose in mg) = 168 mg

Therefore, the nurse should prepare to administer 168 mg of zidovudine IV to the client.

Correct Answer is ["0.7"]

Explanation

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

- Convert the child's weight from pounds to kilograms by dividing by 2.2

- Calculate the dose of filgrastim in mcg by multiplying the weight in kg by the dosage in mcg/kg/day

- Divide the dose in mcg by the concentration of filgrastim in mcg/mL

- Round the result to the nearest tenth

Using these steps, we get:

- (weight in kg) = (88) / (2.2) = 40 kg

- (dose in mcg) = (5) x (40) = 200 mcg

- (volume in mL) = (200) / (300) = 0.667 mL

- (rounded volume in mL) = 0.7 mL

Therefore, the nurse should administer 0.7 mL of filgrastim to this child daily.
