Question 5 of 5
The nurse assists a client with Parkinson's disease 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?
Correct Answer: A
Rationale: The nurse should confirm that pretending to step over a crack is an effective technique for ambulation in Parkinson's disease. Freezing of gait is common, and visual cues like imagining obstacles can stimulate movement by engaging the brain's motor planning. This compensatory strategy is well-documented in Parkinson's management. Carpet may reduce cues, re-orientation assumes confusion not present, and cognition assessment isn't indicated here, as this is a motor issue, making affirmation the best response.
