Which of the following is a single-use (disposable) item that must be thrown away after one client?

Single-use (disposable) items are those that cannot be properly cleaned and disinfected and must be thrown away after one use or one client — examples include emery boards (the porous cardboard kind), wooden manicure/orangewood sticks, cotton, and disposable gloves. Multi-use (reusable) items, such as metal shears, combs, and metal-core implements, are made of materials that can be cleaned and disinfected for reuse. Knowing which category a tool falls into is essential for preventing cross-contamination and is commonly tested.
