A nurse is teaching a client about risk factors for osteoarthritis. Which of the following factors should the nurse include? (Select all that apply.)

Choice A reason: Bacterial infection is not a risk factor for osteoarthritis. It is more relevant to septic arthritis, which is an infectious condition involving joint inflammation due to pathogens. Choice B reason: Diuretics are not directly linked to osteoarthritis. While they may affect fluid balance and electrolyte levels, they do not contribute to cartilage degeneration or joint wear. Choice C reason: Aging is the most significant risk factor for osteoarthritis. As people age, cartilage wears down, joint fluid decreases, and bone changes occur, all contributing to the development of osteoarthritis. Choice D reason: Smoking has been associated with increased inflammation and impaired healing, which may exacerbate joint degeneration. While not a primary cause, it is considered a modifiable risk factor.
