Which statement about cast application is true?

• A. It should be applied only by physician assistants
• B. It should fit snugly but still allow adequate circulation
• C. It should be as loose as possible
• D. It should be applied over a swollen joint without concern for circulation

Answer: (B)

When a cast is applied, the goal is to immobilize the injured part while preserving blood flow. A properly applied cast fits snugly enough to hold the bones in place, but it must still allow adequate circulation and room for swelling. Padding and smooth molding help distribute pressure and prevent skin injury. After application, routinely assess distal circulation and sensation—look for normal color and warmth, quick capillary refill, and the ability to move and feel the toes or fingers. If circulation is compromised or swelling increases, the cast may need adjustment. Casts are placed by trained personnel, with careful attention to swelling and padding to keep the balance between immobilization and circulation.
