Final answer:
A superficial pressure ulcer that appears as an abrasion, blister, or shallow crater should be documented as a Stage II pressure ulcer by the nurse.
Step-by-step explanation:
If a patient's pressure ulcer is superficial and presents clinically as an abrasion, blister, or shallow crater, the nurse would document this pressure ulcer as a Stage II ulcer. This classification is consistent with the stages of pressure ulcers, where Stage II represents partial thickness loss of dermis and presents as a shallow open ulcer with a red-pink wound bed without slough.
Whereas Stage I is intact skin with non-blanchable redness, Stage III involves full-thickness tissue loss with possible visible subcutaneous fat, and Stage IV represents full-thickness tissue loss with exposed bone, muscle, or tendon.
