Final answer:
A stage 3 pressure sore is an advanced ulcer with deep tissue damage that can reveal adipose tissue, has a potential foul odor, and may exhibit black edges and slough. Proper care is critical to prevent severe complications.
Step-by-step explanation:
Characteristics of a Stage 3 Pressure Sore
A stage 3 pressure sore is an advanced bedsore, where damage has extended into the lower layers of the skin and underlying tissue. At this stage, there is a deep, crater-like ulcer showing adipose (fat) tissue and the destruction of the affected area is more severe. The sore may have a foul odor, and the edges can be black due to tissue necrosis. Slough (dead tissue) may be present, which is often yellow, tan, or green in color, and there may be signs of infection. It's crucial to recognize and treat these sores promptly to prevent further complications, such as infection spreading to the bone (osteomyelitis) or bloodstream (sepsis), both of which can be life-threatening.
Bedsores are most commonly seen in patients who are immobile, such as the elderly or those with conditions such as diabetes, which can impair circulation. Regularly turning patients and providing proper wound care are essential components of preventing and treating bedsores. In more severe cases like stage 3, surgical intervention may be required to remove necrotic tissue and promote healing.
