Which method can ensure a patient understands instructions?

To ensure that a patient fully understands the instructions provided, having the patient repeat them back is an effective technique. This method is grounded in active engagement and reinforces comprehension by requiring the patient to process and articulate the information. When patients are asked to repeat instructions, it allows healthcare providers to assess the patient's understanding and clarify any misunderstandings on the spot, thus improving adherence to medical advice.

In contrast, using medical jargon may confuse patients rather than clarify the instructions, leading to misunderstandings. Writing instructions in a different language could support comprehension for patients who are non-native speakers, but it does not guarantee understanding since literacy levels and language proficiency can vary. Discussing the instructions only once fails to give patients the opportunity to ask questions or seek clarification, which is critical for ensuring they fully grasp important medical information.
