An older adult client presents with chronic constipation, decreased urine output, and a history of recurrent urinary tract infections (UTIs). Which of the following conditions should the nurse evaluate as a likely contributing factor to the client's current symptoms?

A. Age-related decreased thirst perception: Older adults often experience a reduced sensation of thirst, which can lead to inadequate fluid intake. Low fluid intake contributes to chronic constipation, concentrated urine, and increased susceptibility to urinary tract infections. B. Use of a bedside commode for toileting: While convenient, a bedside commode does not directly cause constipation or UTIs. It may influence toileting habits, but it is not a primary contributing factor to the symptoms described. C. Increased dietary fiber intake: Higher fiber intake generally improves bowel regularity and prevents constipation. It is unlikely to contribute to the client’s chronic constipation and associated urinary issues. D. Daily fluid intake of 2,500 mL: Adequate fluid intake at this level usually helps prevent constipation and urinary tract infections. The client’s symptoms suggest insufficient fluid intake, making this inconsistent with the clinical picture.
