Final answer:
The scapula, ischial tuberosities, and vertebral spinous process are susceptible to developing pressure sores in the sitting position.
Step-by-step explanation:
Pressure sores, also known as pressure ulcers or bedsores, can occur when there is prolonged pressure on the skin and underlying tissues. While pressure sores are often associated with lying in one position for an extended period, they can also develop in individuals who spend long hours in a sitting position. This is particularly relevant for people who use wheelchairs or are otherwise sedentary for extended periods.
The bony prominences that are susceptible to developing pressure sores are the scapula, ischial tuberosities, and vertebral spinous process in the position sitting.
