What is the first action to take when Mr. Raymond is found walking without a mask?

The first action to take when Mr. Raymond is found walking without a mask is to direct him back to his room and place his O2 cannula. This approach ensures immediate safety and compliance with health protocols. When a patient is walking around without a mask, it raises concerns about both their own health and the protection of others, especially in a healthcare environment.

By first guiding Mr. Raymond back to his room, you can ensure he is in a controlled environment where you can monitor his condition more effectively. Placing the O2 cannula promptly addresses any potential respiratory needs he may have and ensures that he is receiving the necessary oxygen support. This action prioritizes his immediate well-being and adheres to infection control measures.

Other choices may not address the immediate health needs or situation effectively. Choosing to place him on a pulse oximeter or calling for medical assistance might be appropriate later but do not take care of the essential task of ensuring he has his oxygen support. Instructing him on proper mask procedures is also important but should follow the immediate action of ensuring he is stable and properly supported with oxygen.
