What type of burn typically results in painful thickened blisters?

1. Superficial burn

2. Partial-thickness burn

3. Full-thickness burn

4. Friction burn

The correct answer is: Partial-thickness burn

A partial-thickness burn, also known as a second-degree burn, is characterized by damage that extends through the epidermis and into the dermis. This type of burn often leads to the formation of painful blisters that are thickened due to the fluid accumulation beneath the damaged skin layers. The pain associated with partial-thickness burns is significant because the nerve endings in the dermis are still intact and can respond to stimuli. The presence of thickened blisters is a key distinguishing feature of partial-thickness burns. These blisters can vary in size and might leak fluid, potentially leading to infection if not properly cared for. Treatment often focuses on pain management, keeping the area clean, and protecting the blisters to promote healing while minimizing scarring. Understanding the characteristics of different burn types is essential for effective assessment and management in a clinical setting.
