Which cast-care practice should be avoided?

• A. Getting the cast wet
• B. Elevating the limb
• C. Keeping skin under the cast clean and dry
• D. Inspecting skin around the cast

Answer: (A)

Moisture around a cast compromises both the cast and the skin beneath it. Getting the cast wet should be avoided because water can soften plaster, cause cracking or loosening of the cast, and promote skin maceration, irritation, and infection under the cast. A wet cast is harder to dry thoroughly and can create a warm, damp environment that fosters bacteria or fungi.

Elevating the limb helps reduce swelling and improves comfort, so it’s a beneficial care practice. Keeping skin under the cast clean and dry prevents dermatitis and infection, which is essential for healing. Inspecting skin around the cast allows early detection of pressure, redness, or sores, so problems can be addressed promptly.

Thus, the practice to avoid is getting the cast wet.
