Which action by a nurse indicates correct usage of a cane by a client?

The correct choice reflects the ideal positioning of the cane for optimal support and stability during ambulation. When the top of the cane is parallel to the client’s waist, it ensures that the cane is at the appropriate height for the user's body. This correct height allows the client to maintain a proper posture and leverage, improving balance and reducing the risk of falls.

This positioning also helps the user engage the correct muscles while walking, which can alleviate undue stress on joints, especially in those with mobility issues. Ensuring that the cane is at the correct height is a fundamental aspect of cane usage that directly affects the effectiveness of the cane in providing support.

In contrast, moving the cane forward at shoulder height is incorrect, as this would not provide proper support and might hinder the client's ability to maintain balance. Holding the cane on the weaker side is also incorrect; the cane should be used on the stronger side to provide stability for the weaker limb during ambulation. Lastly, moving the weaker limb forward with the cane is not advisable, as the proper technique involves moving the cane first, followed by the weaker leg, to ensure the client maintains proper stability and balance.
