Final answer:
A nurse is using reflective listening from the OARS technique when she says, 'I hear you saying that you would like to increase your walks from one day a week to three days a week', directly mirroring the client’s words.
Step-by-step explanation:
A good example of a nurse 'reflecting' back what a client says using the OARS technique is: I hear you saying that you would like to increase your walks from one day a week to three days a week. This statement directly acknowledges and mirrors the client's own words, showing that the nurse is actively listening and validating the client's thoughts. This reflective listening is a core aspect of the OARS (Open-ended questions, Affirmations, Reflective listening, and Summaries) technique used in motivational interviewing to enhance engagement and foster a supportive dialogue.
