A nurse is providing teaching for a client who has a prescription for home oxygen. Which of the following instructions should the nurse include?

Choice A reason: Posting a "No Smoking" sign in the home is crucial for safety when using oxygen. Oxygen supports combustion, and even a small spark can cause a fire or explosion. Making sure everyone in the home is aware of the no smoking rule is essential to prevent accidents. Choice B reason: While securing oxygen containers to prevent them from falling is important, attaching them to a fixed object is not the best practice for portability and accessibility. The main focus should be on ensuring they are stable and stored safely in an appropriate area. Choice C reason: Storing spare oxygen containers in a closet is unsafe. Oxygen tanks should be stored in a well-ventilated area, away from heat sources and flammable materials, to prevent the risk of fire or explosion. Choice D reason: Notifying the fire department about the use of oxygen in the home is not a common instruction given to patients. While it may add a layer of safety in case of emergency, it is not a standard practice compared to posting a "No Smoking" sign.
