Which of the following is not a risk factor for pressure injuries?

• A. Immobility
• B. Adequate nutrition
• C. Mental status changes
• D. Age

Answer: (B)

Adequate nutrition helps protect the skin and supports tissue healing, so it is not a risk factor for pressure injuries. In fact, proper nutrition provides the building blocks for collagen formation, immune function, and cell turnover, all of which help the skin withstand pressure and recover from-minor damage.

Immobility increases risk because prolonged pressure over bony prominences reduces blood flow and oxygen to the tissue, making breakdown more likely. Mental status changes contribute too, since confusion or cognitive impairment can hinder the ability to reposition, recognize discomfort, or communicate needs, leading to sustained pressure and moisture issues. Age is a factor as well because older skin tends to be thinner, drier, and less elastic, with more comorbidities that can impair circulation and healing.

So, while immobility, mental status changes, and age raise the risk, having adequate nutrition does not; it mitigates risk by supporting skin integrity and healing capacity.
