Question 1 of 5

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.)

Correct Answer: 0.4

Rationale:
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.
