Final answer:
The pressure ulcer was most likely caused by sitting on a bed in one position for long periods of time.
Step-by-step explanation:
A pressure ulcer, also known as a bed sore or decubitus ulcer, is most likely caused by sitting or lying in one position for long periods of time. This constant pressure on the skin decreases blood flow and damages the underlying tissues. Factors such as poor nutrition, inadequate hydration, and medical conditions that affect blood flow can also contribute to the formation of pressure ulcers.
For Heather, sitting on a bed in one position for long periods of time while in the hospital is the most likely situation that caused the pressure ulcer to form. When a person is immobile or unable to change positions frequently, the sustained pressure on certain areas of the body can lead to the development of pressure ulcers.
