A postoperative patient is being discharged home with acetaminophen/hydrocodone [Lortab] for pain. The patient asks the nurse about using Tylenol for fever. Which statement by the nurse is correct? "It is not safe to take over-the-counter drugs with prescription medications." "Taking the two medications together poses a risk of drug toxicity." "There are no known drug interactions, so this will be safe." "Tylenol and Lortab are different drugs, so there is no risk of overdose."
