Which of the following is an example of personal protective equipment (PPE)?

Personal protective equipment (PPE) is designed to protect healthcare workers and patients from exposure to hazards such as infection, chemicals, and other dangerous substances. Gowns are a prime example of PPE as they provide a barrier to prevent the transmission of infectious agents. They are typically used during procedures that may expose healthcare professionals to blood, body fluids, or other potentially infectious materials.

The other items listed do not serve the same protective purpose. Scissors are tools used for cutting and do not provide any form of protection. Notebooks are for taking notes and organizing information, and oxygen masks, while they do provide a form of protection for the patient receiving oxygen, do not fit the category of traditional personal protective equipment worn by healthcare workers for their safety during exposure to hazards.
