The nurse is planning care for a patient with an exacerbation of multiple sclerosis (MS). Which is the correct intervention for the nurse to include in the plan of care for bladder control?

Rationale: A. While a high-fiber diet helps prevent constipation, it does not directly address bladder control issues. MS patients often experience neurogenic bladder dysfunction, which requires specific urinary management strategies rather than dietary modification. B. Baclofen is a muscle relaxant used to treat spasticity, particularly in the limbs, but it does not improve bladder control. Using it for urinary symptoms would be ineffective. C. Timed voiding (also called scheduled or prompted voiding) helps manage urinary incontinence and retention in MS by encouraging regular bladder emptying. This reduces the risk of urinary tract infections (UTIs), bladder overdistension, and incontinence, and promotes autonomy. It is a noninvasive, evidence-based nursing intervention for neurogenic bladder in MS. D. Indwelling catheters are not routinely used due to the risk of infection, urethral trauma, and decreased bladder tone. Catheterization is reserved for acute urinary retention or severe complications, not as a first-line strategy for bladder management in MS.
