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 ["30"]

Explanation

The correct answer is 30 mL. To find the answer, we can use the following steps:

- Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations

- Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

- (total daily dose in mg) = (150) x (2) = 300 mg

- (volume to be administered in mL) = (300) / (10) = 30 mL

- (rounded volume to be administered in mL) = 30 mL

Therefore, the Nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.

Correct Answer is ["10"]

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 volume of amoxicillin suspension in mL by dividing the dose in mg by the concentration in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

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

- (volume in mL) = (500) / (250 / 5) = 10 mL

- (rounded volume in mL) = 10 mL

Therefore, the nurse should administer 10 mL of amoxicillin suspension to the child.
