Question 1 of 5

A nurse is caring for an infant who weighs 12 lb and is prescribed cefuroxime sodium 15mg/kg PO every 12 hr. Available is cefuroxime sodium oral solution 125mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Your Answer:

Correct Answer: 3.2 mL

Rationale:
To calculate the correct dosage for the infant, we first need to determine the infant's weight in kg. 12 lb is approximately 5.45 kg.
Then, we calculate the total dose: 15 mg/kg * 5.45 kg = 81.75 mg per dose. Next, we convert the dose to mL using the concentration of the oral solution: 125 mg/5 mL = 25 mg/mL.
Therefore, 81.75 mg ÷ 25 mg/mL = 3.27 mL. Since we need to round to the nearest tenth, the correct answer is 3.2 mL.

Summary:
-
Choice A: Incorrect, as it does not follow the correct calculation method.
-

Choices B-G: Irrelevant as they do not provide the correct calculation for the dosage.
