Question

Which of the following describes bullae that characterized second-degree burns? A. Nodules filled with liquid material B. Blister-like elevations less than \(1 \mathrm{~cm}\) in diameter C. Fluid-filled blisters greater than \(1 \mathrm{~cm}\) in diameter D. Elevated patches that are confined to outer areas

Short answer

Answer: Fluid-filled blisters greater than 1 cm in diameter.

Step-by-step solution

Understand the definitions

To answer this question, it's important to understand what bullae are and the characteristics of second-degree burns. Bullae are large blisters that form on the skin due to various causes, including burns. Second-degree burns affect both the outer and underlying layer of skin, causing pain, redness, and blistering.

Evaluate each option

Now, let's go through each option and evaluate if it accurately describes bullae in the context of second-degree burns. A. Nodules filled with liquid material: This option refers to a structure that is solid and not a blister. It is not accurate for second-degree burns' bullae. B. Blister-like elevations less than \(1 \mathrm{~cm}\) in diameter: This option describes small blisters, but bullae are typically larger blisters. So, this option is not accurate for second-degree burns' bullae. C. Fluid-filled blisters greater than \(1 \mathrm{~cm}\) in diameter: This option accurately describes bullae, which are large fluid-filled blisters, and is consistent with the characteristics of second-degree burns. D. Elevated patches that are confined to outer areas: This option does not describe the bullae, as they are not confined to outer areas. Second-degree burns affect both the outer and underlying layers of the skin.

Choose the correct answer

Based on our analysis, the correct answer to this question is: C. Fluid-filled blisters greater than \(1 \mathrm{~cm}\) in diameter.
