Question 1 of 5
A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 28 lb. The amount available is acetaminophen 120 mg/5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 5.3
Rationale:
To calculate the correct dose, we first convert the child's weight from lb to kg: 28 lb / 2.2 = 12.73 kg.
Then, we multiply the weight by the dose (10 mg/kg): 12.73 kg * 10 mg/kg = 127.3 mg. Next, we convert mg to mL using the available concentration: 127.3 mg / 120 mg = 1.06 mL, which rounds to 1 decimal place as 5.3 mL.
Therefore, the nurse should administer 5.3 mL. Other choices are incorrect because they do not follow the correct conversion and calculation steps, leading to inaccurate dosing.
