A nurse is providing discharge teaching for a client who will be receiving oxygen therapy at home. Which of the following instructions should the nurse include in the teaching?

A. "You should use woolen blankets on your bed": Woolen blankets are highly flammable and pose a fire risk when oxygen is in use. Clients should avoid using woolen or synthetic materials near oxygen tanks and instead use materials that are less likely to catch fire. B. "You should purchase a fire extinguisher for your home": Oxygen is highly flammable, and having a fire extinguisher readily available in the home is crucial for safety. The nurse should encourage the client to keep a fire extinguisher nearby in case of any oxygen-related fire emergencies. C. "You will no longer be able to use an electric razor": Electric razors are safe to use while on oxygen therapy, as they are not typically a fire hazard. However, clients should avoid using razors that require flammable substances, such as shaving cream, around oxygen. D. "Family members who smoke must do so at least 6 feet away from the oxygen tank": Smoking near oxygen tanks is extremely dangerous, and family members should avoid smoking entirely in areas where oxygen is in use. It is important to maintain a safe distance of at least 10 feet or more from oxygen sources when smoking.
