A nurse is reinforcing teaching with a client who is to have a plaster cast applied to his right arm. Which of the following information should the nurse include in the teaching?

A. The client should use a hair dryer on a warm setting to relieve itching inside the cast is incorrect. Using a hair dryer could cause skin burns or damage the cast. Additionally, the client should avoid introducing moisture into the cast, which could lead to skin irritation or infection. B. The client's extremity should be elevated after the cast is applied is correct. Elevating the extremity helps reduce swelling and inflammation during the initial phase after cast application. It is important to elevate the limb above the level of the heart to promote venous return and reduce swelling. C. The client can shower with the cast after 24 hr is incorrect. The plaster cast should not get wet. The nurse should instruct the client to keep the cast dry at all times. A plastic cover or cast protector should be used when showering to prevent moisture from seeping into the cast. D. The client should keep the cast covered until it is dry is incorrect. It is true that the cast should be kept dry, but keeping it covered is not enough. The primary concern is preventing moisture and ensuring the plaster cast is allowed to air dry in a well-ventilated area without getting wet.
