Which of the following does NOT contribute to pressure ulcer risk?

Socioeconomic status does not directly contribute to the physiological factors that lead to pressure ulcer risk. Pressure ulcers primarily occur due to localized ischemia caused by prolonged pressure on the skin, which affects people regardless of their socioeconomic background. While socioeconomic status can influence access to healthcare resources, education, and support systems that may indirectly affect an individual's overall health and ability to manage conditions that could lead to pressure ulcers, the immediate risk factors are linked more closely to skin temperature, mobility, and sensation.

Skin temperature plays a role as elevated temperatures can increase metabolism in the skin, leading to a higher risk of tissue breakdown if pressure is not alleviated. Mobility is crucial because individuals who are less mobile are more likely to remain in one position for extended periods, increasing pressure on bony prominences. Sensation is also a key factor because individuals who have compromised sensation may not respond to discomfort or pain, thereby failing to change position and relieve pressure, further raising their risk for ulcer formation.
