C. Sharps disposal containers are missing from the hospital's plan. Sharps are any objects that can penetrate the skin, such as needles, scalpels, and broken glass, and they pose a significant risk of infection if not disposed of properly. Sharps disposal containers are specifically designed to safely contain these items and prevent accidental needle sticks or other injuries. It is essential that hospitals have a plan for proper disposal of sharps, including the use of containers and regular disposal procedures, to reduce the risk of worker exposure to blood-borne illnesses.
