Which factor is least likely to contribute to the formation of pressure sores?

Routine exercise is least likely to contribute to the formation of pressure sores because it promotes circulation and helps maintain skin integrity. When individuals engage in regular physical activity, they are more likely to shift positions, which alleviates constant pressure on any one area of the skin. This movement is vital in preventing the sustained pressure that can lead to pressure sores.

In contrast, inadequate nutrition, prolonged bed rest, and moist skin conditions are all factors that can increase the risk of developing pressure sores. Inadequate nutrition can compromise skin health and make the skin more susceptible to damage. Prolonged bed rest results in prolonged pressure on specific areas of the body, leading to ischemia and subsequently, pressure sores. Lastly, moist skin conditions can weaken the skin barrier, making it more vulnerable to friction and injury, further contributing to the risk of pressure sores.
