An elderly man with chronic obstructive pulmonary disease (COPD) relies on home oxygen treatment. During a home visit, the community nurse notices the man using his oxygen with a packet of cigarettes nearby, putting himself at risk. He has a long history of smoking and poor health factors, but wishes to remain independent in his home. The nurse must determine the best way to address the safety issue while respecting the man's autonomy and right to make his own choices.
