A nurse is planning care for a client who has cystitis. Which of the following interventions should the nurse include in the plan?

Cystitis is the inflammation of the bladder, typically resulting from a bacterial infection. The goal of nursing care is to eradicate the pathogen while minimizing irritation to the inflamed bladder mucosa. Dietary choices play a significant role in managing symptoms like urgency and dysuria during the acute phase of the illness. A. This instruction is incorrect. Clients must be taught to complete the entire prescribed course of antibiotics, even after symptoms like dysuria disappear. Stopping the medication prematurely contributes to antibiotic resistance and increases the likelihood of a recurrent or persistent infection. B. While hydration is important, orange and grapefruit juices are highly acidic. Acidic foods and beverages can irritate the already inflamed lining of the bladder, worsening the pain and urgency associated with cystitis. Patients are generally advised to choose less irritating fluids, such as plain water. C. Iced tea contains caffeine and sometimes high levels of sugar, both of which are bladder irritants. Caffeine acts as a diuretic and a stimulant that can increase bladder spasms and frequency, making it an inappropriate fluid choice for someone suffering from an active case of cystitis. D. Avoiding carbonated beverages is an appropriate intervention. Carbonation can irritate the bladder wall, exacerbating the symptoms of cystitis. Patients should be encouraged to focus on water intake and avoid known irritants like soda, caffeine, and alcohol until the inflammation has completely subsided.
