A nurse is teaching a client about the use of cognitive reframing for stress management. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Progressive muscle relaxation reduces physical tension but is not cognitive reframing. It targets somatic stress responses by relaxing muscles, not addressing cognitive distortions. Reframing involves altering thought patterns, making this statement unrelated to the taught stress management technique. Choice B reason: Cognitive reframing involves replacing negative thoughts with positive ones to alter stress perception. This statement reflects understanding, as it targets cognitive distortions, a core component of cognitive-behavioral therapy, reducing stress by changing maladaptive thought patterns in the prefrontal cortex. Choice C reason: Controlling blood pressure and heart rate refers to biofeedback, not cognitive reframing. Biofeedback uses physiological monitoring to manage stress, while reframing addresses cognitive processes, making this statement incorrect as it does not reflect the taught cognitive strategy. Choice D reason: Focusing on a mental image and breathing describes guided imagery or meditation, not cognitive reframing. These techniques reduce stress through visualization, not by altering thought patterns, making this statement unrelated to the cognitive approach taught for stress management.
