What can indicate that a molded cast is drying properly?

A molded cast drying properly can be indicated by its ability to maintain its shape. When a cast is newly applied, it is often malleable and begins to harden as it dries. The retention of its shape signifies that the casting material has properly set and solidified, ensuring that it will effectively immobilize the underlying structures, providing the necessary support for healing.

Other options suggest different scenarios that may not correlate directly with proper casting techniques. For example, if a cast feels cool to the touch, it may simply indicate that the casting material is in the early stages of curing, but it does not necessarily confirm that it has dried properly. Warmness felt by the client could indicate circulation issues or deterioration of the casting material, which might be concerning. Discoloration of the cast may result from several factors, including moisture or contamination, and does not reflect appropriate drying or a successful molding process.

Therefore, the ability of the cast to maintain its original mold shape is the most reliable indicator of proper drying and set.
