Final answer:
A Stage 1 pressure ulcer is identified by non-blanchable reddish-purple discoloration of the skin without any breaks or loss of skin thickness. Bedsores arise from prolonged pressure, leading to reduced blood flow and potentially necrotized tissue, which requires immediate treatment.
Step-by-step explanation:
A Stage 1 pressure ulcer is characterized by non-blanchable erythema of intact skin. In simpler terms, this refers to an area of red skin that does not turn white when pressure is applied, indicating that a sore is starting to develop. For a Stage 1 pressure ulcer, the correct descriptor would be (a) Reddish-Purple Discoloration, as this stage does not involve skin break or tissue loss. A superficial skin break or blister would indicate a more advanced ulcer, likely a Stage 2. Partial skin thickness loss is indicative of Stage 3, and full-thickness skin loss signifies a Stage 4 pressure ulcer, which can involve damage to muscle, bone, or supporting structures.
Bedsores, also known as decubitis ulcers, occur from prolonged pressure on skin over bony areas of the body, leading to reduced blood flow and potential tissue death or necrosis. These are commonly seen in immobilized or elderly patients and can be prevented by regularly repositioning the patient to alleviate pressure. When necrotized tissue is not promptly removed and these sores become infected, there can be severe health consequences.
