Which intervention should a nurse implement for a patient diagnosed with dysuria?

Using warm sitz baths as comfort measures is an effective intervention for a patient diagnosed with dysuria because this method helps to alleviate pain and discomfort associated with urination. The warm water can soothe the inflamed tissues of the urinary tract and provide a sense of relief, making it easier for the patient to manage their symptoms. This approach can also help relax the pelvic muscles, further alleviating any pelvic discomfort they may be experiencing.

Increasing fluid intake significantly might seem beneficial due to the idea that more fluids can help flush out bacteria, but it can also lead to increased urgency and discomfort during urination in someone already experiencing pain. Encouraging the patient to hold urine longer can worsen the symptoms of dysuria and may lead to further complications such as urinary retention or increased inflammation in the urinary tract. While administering analgesics can provide quick pain relief, it does not address the underlying issue or comfort the patient in a holistic manner like warm baths can. Thus, the option of using warm sitz baths effectively combines comfort with symptom management, making it the most suitable intervention in this context.
