A nurse is implementing a bladder training program for a client who had a stroke. Which of the following interventions should the nurse take first?

A. Incorrect. Assisting the client with relaxation techniques can be helpful in managing bladder training, but determining the client's voiding pattern is the first step in designing an effective program. B. Incorrect. Discouraging the intake of carbonated beverages might be part of the bladder training plan, but the first step is to assess the client's current voiding pattern. C. Incorrect. Offering toileting opportunities every 1 to 2 hours is part of the bladder training program, but determining the client's voiding pattern is the initial action. D. Correct. The nurse should first determine the client's pattern for voiding, including the frequency of voiding and any patterns of urgency or incontinence. This information is essential to tailor the bladder training program to the client's individual needs.
