A nurse is teaching the family of a client with Parkinson's disease on how to assist them at home. Which statement by the family indicates further education is needed?

Choice A rationale Increasing dietary fiber is a critical intervention for individuals with Parkinson disease due to the high prevalence of chronic constipation. This gastrointestinal dysfunction results from decreased autonomic nervous system activity and side effects of dopaminergic medications which slow intestinal transit time. Decreasing fiber would exacerbate this condition, potentially leading to fecal impaction or bowel obstruction. Therefore, recommending a decrease in fiber demonstrates a lack of understanding regarding the necessary nutritional support for maintaining regular bowel movements. Choice B rationale The installation of bath bars is an essential safety modification to prevent falls in the home environment. Parkinson disease is characterized by postural instability, a shuffling gait, and impaired balance, all of which significantly increase the risk of fractures and head injuries. Bathrooms are high risk areas due to slippery surfaces and the need for transitional movements. Installing assistive devices before the client arrives home ensures that the environment is structurally prepared to support their physical limitations. Choice C rationale Posture exercises are vital for managing the progressive musculoskeletal changes associated with this neurological disorder. Patients often develop a stooped, forward leaning posture known as camptocormia, which shifts their center of gravity and impairs respiratory expansion. Teaching and performing specific exercises helps to counteract muscle rigidity and maintain a more upright alignment. This intervention supports better balance and can improve the client's overall mobility and confidence during ambulation, reducing the likelihood of falling forward. Choice D rationale Performing range of motion exercises three times daily is a standard recommendation to mitigate the effects of muscle rigidity and bradykinesia. These exercises help maintain joint flexibility and prevent the development of painful contractures that occur when muscles remain in a shortened state. Consistent movement also promotes circulation and helps the client maintain the ability to perform activities of daily living. Adhering to a frequent schedule ensures that the musculoskeletal system remains as functional as possible throughout the day.
