A female client with Alzheimer's disease develops edema in both ankles. The healthcare provider examines the client and determines she is in relatively good health with no cardiac or renal health problems. Which action should the practical nurse (PN) take?

A. Assist with ambulation several times a day: Ambulation promotes venous return and helps reduce dependent edema in the ankles. Encouraging movement is the most direct and effective intervention to manage edema when there are no underlying cardiac or renal problems. B. Provide low protein snacks between meals: Dietary protein restriction is not indicated for mild, dependent edema in a healthy client. Low protein intake would not reduce edema and may negatively affect nutritional status. C. Remind the client to sit upright while awake: Sitting upright can prevent respiratory complications and promote comfort, but it has minimal effect on ankle edema, which is influenced more by activity and circulation. D. Encourage a regular toileting schedule: Maintaining a toileting schedule supports continence and comfort but does not directly impact the management of peripheral edema.
