An adolescent who sustained a tibia fracture in a motor vehicle accident has a cast. What should the nurse do to help relieve the itching?
A. Apply hydrocortisone cream under the cast using sterile applicator
B. Apply cool air under the cast with a blow-dryer
C. Use sterile applicators to scratch the itch
D. Apply cool water under the cast
Correct Answer: B. Apply cool air under the cast with a blow-dryer
Itching underneath a cast can be relieved by directing the blow-dryer, set, on the cool setting, toward the itchy area. Therefore, one of the best ways to relieve moisture is, of course, to dry it off. The client may find ways to blow cool air into and through the cast. The client may be able to do that using specific settings on a hairdryer, for example.
Option A: Do not stick objects such as coat hangers inside the splint or cast to scratch itching skin. Do not apply powders or deodorants to itching skin. If itching persists, contact a doctor.
Option C: Skin breakdown can occur if anything is placed under the cast. Therefore, the client should be cautioned not to put any object down the cast in an attempt to scratch. Scratching in this way could lead to an open wound or developing sores.
Option D: Moisture weakens plaster and damp padding next to the skin can cause irritation. Use two layers of plastic or purchase waterproof shields to keep the splint or cast dry while showering or bathing.
