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?

A. Assessing the client's cognition may be appropriate if there are concerns about cognitive function, but in this scenario, the client's response indicates a coping mechanism for freezing episodes rather than cognitive impairment.B. Confirming that the client's technique of pretending to step over a crack is an effective strategy acknowledges the client's self-initiated coping mechanism for freezing episodes, which can help promote independence in ambulation.C. Assisting the client to a carpeted area may help reduce the risk of falls but does not directly address the freezing episode or the client's coping strategy.D. Reorienting the client to the present location and circumstances is unnecessary as the client's response indicates a conscious coping strategy rather than confusion or disorientation.
