Which statement by the nurse is correct? "Taking these two medications together poses a risk of drug toxicity" "It is not safe to take any over-the-counter drugs with prescription medications" "Tylenol and Vicodin are different drugs, so there is no risk of overdose" "There are no known drug interactions, so this will be safe"
