Final answer:
Pressure ulcers commonly occur on body parts with prominent bones under the skin, including the buttocks, heels, scapula, elbows, and occasionally, the abdomen. They arise from unrelieved pressure leading to reduced blood flow and tissue necrosis. Proper care includes regular repositioning to prevent these ulcers and treating necrotic tissue to avoid life-threatening infections.
Step-by-step explanation:
Common areas for pressure ulcers, also known as bedsores or Decubitus ulcers, are parts of the body where bones are close to the skin surface, leading to reduced blood flow when pressure is unrelieved. These areas include:
- Buttock
- Heels
- Scapula
- Elbows
- Abdomen (less common compared to the other sites)
Pressure ulcers occur due to constant, long-term pressure that causes tissue necrosis. They are most prevalent among immobile patients, including the elderly or those with debilitating conditions. To prevent ulcers, caregivers are advised to regularly reposition patients to alleviate pressure on susceptible areas. If not treated properly by removing necrotic tissue, infections from bedsores can be life-threatening.
Injuries to the skin, such as burn, wounds, scars, calluses, can be due to sharp objects, heat, or excessive pressure or friction. Calluses and corns, like ulcers, result from abrasive pressure on the skin.
