What instruction should the nurse give to prevent stiff or frozen shoulder in a client with a right arm cast?

To prevent stiff or frozen shoulder in a client with a right arm cast, the most effective instruction is to lift the shoulder of the casted arm over the head periodically. This action helps maintain mobility in the shoulder joint, which is crucial when an arm is immobilized due to a cast. Limited movement can lead to joint stiffness, and actively engaging the shoulder by lifting it helps to preserve its range of motion and function.

Regularly lifting the shoulder also encourages circulation in the area, which can help with healing and reduce the risk of complications associated with prolonged immobility. It serves as an essential practice to counteract the effects of immobilization while ensuring that the client remains within safe limits of movement to avoid stressing the injured arm or the cast itself.

In contrast, keeping the arm elevated at all times may restrict necessary movements and make the shoulder more prone to stiffness. Limiting movement to avoid irritation does not address the need for maintaining joint flexibility. Applying heat can provide temporary relief but does not directly prevent stiffness; rather, it may require active motion interventions to be truly effective.
