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?

A. "I should try to focus on pleasant images to help replace stressful and negative feelings I have.": This statement reflects the use of guided imagery, which promotes relaxation and emotional distraction, but it does not involve altering cognitive perceptions or beliefs about stress. B. "I should reassess the situation and change my perceptions of stress by replacing irrational beliefs.": Cognitive reframing involves identifying and challenging distorted or irrational thoughts and replacing them with more balanced, realistic thinking. This statement demonstrates an understanding of altering cognitive patterns to manage stress effectively. C. "I will tense my muscles for 8 seconds and then relax them to release the tension caused by my stress.": This describes progressive muscle relaxation, a physical technique to reduce somatic tension. While effective for stress management, it does not address thought patterns or cognitive appraisal. D. "I will use my smartwatch to monitor my sleep and heart rate to assist me with gaining voluntary control over my stress.": Using a device for biofeedback helps monitor physiological responses and promote self-regulation, but it does not involve changing thought patterns, which is central to cognitive reframing.
