What is a critical consideration when applying a plaster cast?

• A. It should be thick for durability
• B. It must allow for full mobility
• C. It should be applied evenly and accommodate swelling
• D. It needs to dry immediately

Answer: (C)

When applying a plaster cast, a critical consideration is that it should be applied evenly and accommodate swelling. Proper application is essential to ensure that the cast immobilizes the affected area without creating excess pressure, which could lead to complications such as compartment syndrome. Swelling is a natural response to injury, and if the cast is applied too tightly or without regard for future swelling, it can restrict blood flow and nerve function. This can cause significant pain and potentially lead to more serious complications, requiring removal of the cast. Therefore, it is crucial for the plaster to be layered evenly to distribute pressure uniformly across the limb. While durability and flexibility are important, they are secondary to ensuring that the cast fits properly around the initial swelling, which typically occurs in the days following an injury. A cast that accommodates swelling enhances patient comfort and safety while promoting effective healing.
