Which is NOT part of standard cast care?

• A. Keep extremity elevated for the first day
• B. Do not indent until dry
• C. Do not put anything inside the cast
• D. Apply heat to accelerate drying

Answer: (D)

The main idea is safety and proper immobilization: heat should never be used to speed up drying a cast. Applying heat can burn the skin underneath the cast and can soften or warp the cast material, creating skin injury or loosening the immobilization. Standard cast care focuses on keeping the limb elevated to reduce swelling, not putting anything inside the cast to avoid skin irritation or infection, and avoiding pressure or indentations that could cause pressure sores. If the cast gets wet, let it dry naturally and contact the clinician for guidance; some instructions may allow cool, gentle air to aid drying, but never use heat.
