A Mother Calls the Outpatient Clinic Requesting Information on Appropriate

A mother calls the outpatient clinic requesting information on appropriate dosing for over-the-counter medications for her 13-month-old who has symptoms of an upper respiratory tract infection and fever. The box of acetaminophen says to give 120 mg q4h when needed. At his 12-month visit, the nurse practitioner prescribed 150 mg. What is the nurse's best response?

A) "The doses are close enough; it doesn't really matter which one is given."
B) "It is not appropriate to use dosages based on age because children have a wide range of weights at different ages."
C) "From your description, medications are not necessary. They should be avoided in children at this age."
D) "The nurse practitioner ordered the drug based on weight, which is a more accurate way of determining a therapeutic dose."
