A patient in traction because of a fractured hip from falling is diagnosed with a stage I pressure ulcer. She asks the nurse how she got a pressure ulcer when she had been confined to bed for only 2 days
The nurse's response is based on her knowledge that: 1. erythema can occur in an hour or two, even in a person with healthy skin and ad-equate circulation.
2. it takes several days for a pressure ulcer to form.
3. the pressure ulcer probably occurred when she fell.
4. the cause of pressure ulcers isn't really known.
