A charge nurse is supervising a newly hired nurse who is instructing a client about how to use a walker. For which of the following actions should the charge nurse intervene?

Rationale: A. The client takes multiple steps while holding the walker: Taking several steps while holding the walker increases the risk of imbalance and falls. The correct technique is to move the walker forward one step length, ensure all four legs are stable on the ground, and then take a single step toward it before moving the other leg. B. The client lifts the walker as it is moved forward: The walker should be lifted slightly and placed firmly on the ground to ensure stability with each step. Sliding the walker instead of lifting it can cause uneven movement or tipping, especially on rough surfaces, making lifting the correct method. C. The client advances the walker and takes a step towards it: This is the proper technique for safe use. The client should advance the walker first, then step forward with the weaker leg, followed by the stronger leg, maintaining balance and even weight distribution. D. The client grasps the walker by the hand grips on the upper bars: Proper hand placement on the upper hand grips ensures stability and correct posture during ambulation. Holding the walker anywhere else can cause poor control, imbalance, or wrist strain.
