Which statement by a client using crutches shows understanding of the teaching?

The correct choice emphasizes the importance of maintaining crutch safety and functionality. Keeping the crutch tips dry is crucial because wet or slippery tips can increase the risk of falls and accidents while ambulating. This statement demonstrates that the client understands the need to ensure their crutches are in optimal condition for safe use.

The other options do not capture an accurate understanding of crutch usage. For instance, holding crutches in each hand when sitting down is not the safest approach; a more appropriate technique is to use at least one crutch, if not both, to assist in the sitting process while also utilizing the chair for support. Placing weight on the underarms is inappropriate as it can lead to nerve damage; instead, weight should be distributed primarily through the hands. Lastly, leading with a specific leg when going up stairs can vary depending on the individual's strength and condition, and usually, the guiding principle is to lead with the stronger leg first when ascending. Therefore, the original answer highlights a critical safety aspect of crutch use.
