Which stage of pressure ulcers is characterized by the presence of blisters?

The correct answer is Stage 2, which is characterized by the presence of blisters as well as partial thickness loss of skin. In this stage, the damage extends through the epidermis and may affect the dermis, leading to the formation of blisters that can be filled with clear fluid or blood. This is an important identifying feature of Stage 2 pressure ulcers.

Understanding the characteristics of pressure ulcer stages is crucial for proper assessment and treatment. Stage 1 is identified by non-blanchable erythema and does not involve skin loss, making it distinct from the presence of blisters. Stages 3 and 4 indicate more severe tissue damage, where Stage 3 involves full thickness skin loss exposing subcutaneous tissue, and Stage 4 goes even deeper, potentially exposing muscle, bone, or supporting structures.

Recognizing the features of each stage aids healthcare providers in documenting and treating pressure ulcers effectively, aligning their interventions with the severity of the injury.
