What safety precaution should an HHA take for a client receiving oxygen through a nasal tube?

Maintaining a safe environment for a client receiving oxygen through a nasal tube is crucial due to the nature of oxygen being a flammable element. It supports combustion, meaning that any open flame or spark can lead to fire hazards. By prohibiting smoking in the client's room, the Home Health Aide is reducing the risk of ignition, thereby significantly increasing the client's safety.

Oxygen enrichment can create a situation where even a small spark can ignite materials, making it vital to eliminate any sources of open flames, including smoking. This precaution is essential not only for the safety of the client but also for anyone else present in the environment. Other options, while relevant to safety and visitor etiquette, do not directly address the specific fire hazard that comes with the use of supplemental oxygen.
