Which of the following is NOT a factor contributing to infection susceptibility in nursing homes?

Physical exercise is not a factor that contributes to infection susceptibility in nursing homes. In fact, regular physical activity can bolster the immune system, improve overall health, and enhance mobility, which can help reduce the risk of infections. Engaging in physical exercise promotes better circulation, supports respiratory health, and can aid in maintaining a healthy weight, all of which are beneficial for preventing infections.

In contrast, communal living can increase the risk of infection due to shared spaces and close contact among residents, making the spread of pathogens more likely. Invasive devices, such as catheters or ventilators, can introduce bacteria directly into the body, heightening the risk of infections. Functional impairment in residents may also lead to a greater susceptibility to infections due to reduced mobility, difficulties with personal hygiene, and an increased likelihood of complications from underlying health conditions. Thus, these elements underscore the importance of maintaining a healthy lifestyle, including physical exercise, to mitigate the risk of infections in nursing home settings.
