In taking a medication history, what must a nurse remember to include?

Including over-the-counter (OTC) medications in a medication history is critical because these substances can interact with prescription medications and may affect the patient's overall treatment plan. OTC medications are often overlooked, yet they can cause side effects or alter the efficacy of prescribed medications. Understanding all the medications a patient is using, including OTC options, helps ensure that the nurse can assess potential interactions, monitor for adverse effects, and provide safe medication management.

While the other options may contain inaccuracies about the influence of smoking, alcohol, or herbal products on medication effectiveness, they do not align with the necessity for comprehensive medication history. Recognizing the full spectrum of substances a patient is taking is essential for safe and effective care.
