A nurse is teaching a client who has generalized anxiety disorder about ways to help manage stress. Which of the following instructions should the nurse give the client about using progressive relaxation?

The correct answer is B because progressive muscle relaxation involves systematically tensing and relaxing muscle groups to reduce physical tension associated with anxiety. By tightening a muscle group and then releasing the tension before moving to the next one, the client can become more aware of the physical sensations of stress and learn to relax those muscles consciously. This technique helps the client to differentiate between tension and relaxation, promoting a sense of calmness and reducing overall anxiety levels.

Choice A is incorrect because thinking about a positive outcome does not directly address the physical tension associated with anxiety. Choice C is incorrect as it focuses on visualization rather than muscle relaxation. Choice D is incorrect because it suggests focusing on emotions and writing, which is not a component of progressive muscle relaxation.
