The nurse assists a client with Parkinson's disease (PD) to ambulate in the hallway. The client appears to "freeze" and then carefully lifts one leg and steps forward. The client tells the nurse of pretending to step over a crack on the floor. How should the nurse respond?

Rationale: A. Confirm that this is an effective technique to help with ambulation: Using visual or mental cues, such as imagining stepping over a crack, is a recognized strategy to overcome freezing episodes in Parkinson’s disease. Validating and encouraging this technique supports safe ambulation and promotes independence. B. Assist the client to a carpeted area where he can walk more easily: Changing the walking surface may not prevent freezing and could actually increase the risk of tripping or falling. Parkinson’s freezing often occurs regardless of flooring type. C. Plan to assess the client's cognition after returning to his room: Freezing of gait is a motor symptom rather than a cognitive issue. While ongoing cognitive assessment is important, it does not address the immediate mobility challenge. D. Reorient the client to his present location and circumstances: Freezing episodes in Parkinson’s disease are not due to disorientation. Reorientation would not alleviate the motor difficulty and is not the appropriate response to the client’s described technique.
