Which of the following describes non-expendable items?

Non-expendable items are characterized by their durability and ability to be used multiple times without significant degradation in function or quality. These items are essential in various settings such as sports medicine, where certain tools and equipment are vital for ongoing use in treatment and training. For example, items like orthopedic braces, resistance bands, and crutches are typically categorized as non-expendable because they can withstand multiple uses over time, as opposed to disposable items that are intended for single use and then discarded.

The other options describe different categories of items. Items that can be discarded after use fall under the category of expendable items. Consumables with a limited lifespan typically refer to items that can only be used a few times before they are no longer effective, like bandages or ice packs. Items requiring frequent replacement also do not fit into the non-expendable category, as they are more likely to degrade or become ineffective relatively quickly, necessitating their replacement. Non-expendable items thus represent a more sustainable choice for repeated use in clinical and athletic environments.
