Which of the following observations indicates a safety problem for a client receiving supplemental oxygen?

Storing an extra oxygen tank on its side under the bed is a clear safety hazard for clients receiving supplemental oxygen. Oxygen tanks are high-pressure vessels, and when they are laid on their side, there is a risk of them falling or getting damaged, which could lead to a dangerous situation or even an explosion if the tank were to become punctured. Additionally, having the tank stored in a location that is not easily accessible can impede prompt access in an emergency or contribute to an unsafe cluttered environment around the sleeping area.

In contrast, using a wool blanket is generally safe; materials like wool are not inherently flammable in the presence of oxygen unless exposed to an ignition source. Identifying the location of a fire extinguisher shows awareness and preparedness, which are beneficial for safety. Having a weekly inspection checklist for oxygen equipment indicates good maintenance practices, helping to ensure that the equipment is functioning correctly and safely.
