When assisting Mr. Carlson, who receives oxygen, with shaving, what is the best option?

Using a battery-operated shaver is the best and safest option when assisting Mr. Carlson, who receives oxygen. Oxygen can greatly increase the risk of fire and explosion, especially in an environment where there may be sparks or heat generated from electrical equipment. Battery-powered shavers eliminate this risk as they do not require being plugged into an outlet, thus preventing any potential ignition sources associated with electricity.

Employing a cordless shaver ensures that Mr. Carlson can receive care while minimizing hazards that may arise from his use of oxygen therapy. The other options include using an electric shaver that must be plugged in, which poses a risk due to the nature of oxygen, or asking a nurse to perform the shaving, which may not empower Mr. Carlson to participate in his personal grooming. Encouraging him to grow a beard, while a non-invasive suggestion, does not address the immediate need for shaving and may not be preferable to the patient.
