When taking a medication history on a patient, why should the nurse ask about the use of complementary or alternative therapies?

A. While medication adherence is important, the primary reason for asking about alternative therapies is not due to concerns about compliance. Patients may use alternative therapies alongside prescribed medications, potentially leading to harmful interactions. B. Many complementary and alternative therapies, such as herbal supplements, can interact with prescribed medications, leading to adverse effects or reduced drug efficacy. For example, St. John’s Wort can decrease the effectiveness of certain medications, including anticoagulants and antidepressants. Identifying these therapies ensures patient safety. C. While some natural products may have therapeutic benefits, they are not necessarily more effective than prescribed medications. Healthcare providers should base treatment decisions on evidence-based practice rather than assuming an alternative therapy is superior. D. Financial concerns are important but not the primary reason for inquiring about alternative therapies. The nurse’s main concern is the potential for harmful drug interactions rather than the cost burden on the patient.
