A nurse is contributing to the plan of care for a child who has a urinary tract infection. Which of the following interventions should the nurse include?

A. Evaluate the child's self-esteem. Self-esteem evaluation is important in general nursing care but is not a specific intervention for managing urinary tract infections. B. Encourage frequent voiding. Frequent voiding helps to flush out bacteria from the urinary tract and prevents stasis, which can reduce the risk of urinary tract infections. C. Administer an antidiuretic. Antidiuretics reduce urine output and are not typically used in the treatment of urinary tract infections, which require adequate urine flow to flush out bacteria. D. Restrict fluids. Adequate hydration is important in managing urinary tract infections to promote urine flow and help flush out bacteria. Fluid restriction is not appropriate unless otherwise indicated.
