A Client Has Been Prescribed Acetaminophen and Has Been Instructed

A client has been prescribed acetaminophen and has been instructed by the nurse not to take any over-the-counter (OTC) cough or cold medications without first checking with the health care provider or pharmacist. What is the rationale for this instruction?

A) There could be an increased risk for bleeding in the stomach and within other organs of the body.
B) Cough medications and other OTC drugs could contain acetaminophen, so inadvertent overdose could occur.
