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 ["15"]

Explanation

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

(number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed)

Substituting the given values, we get:

(number of doses) = (18) / (1.2)

Simplifying, we get:

(number of doses) = 15

Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.

Correct Answer is ["75"]

Explanation

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

- Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL

- Multiply the dose in mg per administration by the number of administrations per day

- Round the result to the nearest whole number

Using these steps, we get:

- (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg

- (total daily dose in mg) = (37.5) x (2) = 75 mg

- (rounded total daily dose in mg) = 75 mg

Therefore, the client receives 75 mg of diphenhydramine per day.
