What are pressure ulcers?

• A. Pressure Ulcers
• B. Skin infections caused by bacteria
• C. Chemical burns
• D. Scars from injury

Answer: (A)

Pressure ulcers are localized injuries to the skin and underlying tissues that occur when prolonged pressure, often with shear, reduces blood flow to an area over a bony prominence. This disruption of circulation leads to tissue damage that can range from reddened skin to deep, open wounds. They commonly affect people who are immobile, such as elderly patients in long-term care, and are more likely with factors like incontinence-related moisture and poor nutrition. Typical sites include the sacrum, heels, and other bony areas where pressure is concentrated. They are staged to reflect depth and tissue involvement, guiding treatment and prognosis. These ulcers are not simply infections, burns, or scars: infections are caused by bacteria affecting the skin, chemical burns arise from harmful substances, and scars form after healing from injuries. Preventing them focuses on regular repositioning, good skin care, managing moisture, ensuring adequate nutrition, and using pressure-relieving devices.
