A nurse is teaching a client to manage stress by using progressive relaxation techniques. Which of the following statements by the client indicates an understanding of the teaching?

A. "I should breathe normally while I am performing this relaxation technique.": Progressive relaxation often involves focused, deep, and controlled breathing to enhance muscle relaxation. Simply breathing normally may not maximize the effectiveness of the technique. B. "I should imagine myself in a peaceful, garden-like setting as I begin.": Visualizing a calming scene is a technique used in guided imagery, not progressive muscle relaxation. While relaxation may result, this reflects a different stress-reduction method. C. "I'll compare the sensations I feel when I tense my muscles to what I feel when I relax them.": Progressive relaxation involves systematically tensing and then relaxing specific muscle groups while focusing on the contrast in sensations. D. "I'll use a series of stretches when I practice this technique.": Stretching is part of physical exercise routines and differs from progressive relaxation. The focus in progressive relaxation is on controlled tension and release of muscle groups, not performing stretches.
