Which of the following is the correct way of asking questions when conducting a medication history?

A. "Did you miss any doses of this medication?": This is a closed-ended question that can be answered with a simple yes or no, which limits the information obtained about adherence patterns or reasons for missed doses. B. "Do you know what side effects will be caused by this medication?": This is also a closed-ended question and may lead to incomplete information. Open-ended questions encourage patients to explain their understanding and experiences. C. "What did the doctor tell you the medication was for?": This open-ended question allows the patient to explain their understanding of the medication’s purpose. It encourages discussion, identifies knowledge gaps, and provides insight into adherence and comprehension. D. "Do you know how to take this medication?": While useful, this closed-ended question may elicit a brief yes/no answer. Open-ended alternatives such as “Can you tell me how you take this medication?” provide more detailed and actionable information.
