A child who weighs 28 lb
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?
Correct Answer: 5.3 mL
Rationale:
To calculate the dose, first convert the weight from lb to kg (28 lb ÷ 2.2 = 12.73 kg).
Then, multiply the weight by the dose (10 mg/kg) to get the total dose needed (12.73 kg x 10 mg/kg = 127.3 mg). Next, calculate how many mL are needed using the available concentration (120 mg/5 mL). Divide the total dose needed by the concentration (127.3 mg ÷ 120 mg/5 mL = 5.3 mL).
Therefore, the correct answer is 5.3 mL. Other choices are incorrect because they do not follow the correct conversion and calculation steps, leading to inaccurate results.
