What observation would indicate proper safety protocol for a client receiving supplemental oxygen?

The observation that indicates proper safety protocol for a client receiving supplemental oxygen is ensuring that the client identifies the location of a fire extinguisher. This demonstrates a proactive approach to fire safety, particularly because oxygen supports combustion and increases fire risk. Knowing where a fire extinguisher is located allows the client or caregivers to act quickly in the event of a fire, which is essential when oxygen therapy is involved.

While having smoke detectors installed and avoiding the use of electrical devices are important safety measures, they focus primarily on prevention instead of preparedness. Similarly, the usage of a non-flammable oxygen tank is somewhat misleading, as oxygen tanks themselves are not flammable but can promote combustion. Therefore, the most crucial safety aspect is being prepared with fire safety equipment like a fire extinguisher, which directly enhances safety for clients using supplemental oxygen.
