Final answer:
The best nursing intervention to protect a client with Parkinson's disease from injury is suggesting that the client obtain assistance in performing Activities of Daily Living (ADLs) to minimize the risk of falls and other injuries.
Step-by-step explanation:
The client has Parkinson disease (PD). Which nursing intervention best protects the client from injury? Among the options provided, the best one to protect a client with Parkinson's from injury is C) Suggesting that the client obtain assistance in performing ADLs (Activities of Daily Living). This intervention acknowledges that patients with PD often have motor symptoms such as tremors, muscle rigidity, bradykinesia, and postural instability, which can make activities such as walking, dressing, and eating challenging and potentially dangerous.
