A nurse at an outpatient mental health facility is monitoring effective use of stress management techniques for a client who is attending stress management group therapy. Which of the following statements made by the client indicates effective use of cognitive reframing?

Rationale: A. “I should try to focus on pleasant images to help replace stressful and negative feelings I have.”: This describes guided imagery, a relaxation technique that uses visualization to reduce stress. While helpful, it does not involve the cognitive restructuring. B. “I will use my smartwatch to monitor my sleep and heart rate to assist me with gaining voluntary control over my stress.”: This reflects biofeedback, where physiological responses are tracked and managed through conscious control. It involves physical awareness, not cognitive reinterpretation of stress. C. "I should reassess the situation and change my perceptions of stress by replacing irrational beliefs.”: This is cognitive reframing, a technique that helps clients identify and challenge distorted thinking and replace it with more rational, constructive thoughts to alter their emotional responses to stress. D. "I will tense my muscles for 8 seconds and then relax them to release the tension caused by my stress.”: This refers to progressive muscle relaxation, which targets physical symptoms of stress rather than the cognitive processes addressed in cognitive reframing.
