Which of the following supplies are required for proper handwashing technique?

Proper handwashing technique involves a few essential supplies, and one of the key components is the use of paper towels. After washing hands with soap and water, it's crucial to thoroughly dry them, and paper towels serve this purpose effectively. They're not only absorbent but also help prevent the spread of germs that can occur when hands are dried on shared cloth towels or air driers, which may harbor bacteria.

When using paper towels, individuals can also use them to turn off faucets after washing, preventing re-contamination of clean hands. This practice is important in healthcare settings and everyday hygiene to minimize the risk of infections.

While other options present useful hygiene methods, they do not align with the specific requirement of drying hands effectively after washing, making paper towels the appropriate choice for ensuring proper handwashing technique.
