What is an important instruction for a client using a shoulder immobilizer after humerus surgery?

The correct choice emphasizes the importance of maintaining some level of movement in the forearm and hand to prevent complications such as stiffness and reduced circulation following surgery. While the shoulder and humerus need to remain generally immobilized to promote healing, it is essential for the patient to engage in gentle exercises or movements of the wrist and fingers, as permitted by their healthcare provider. This can help maintain mobility and prevent disuse atrophy of the muscles in the forearm and hand.

The choices that involve keeping the arm immobile at all times, using the immobilizer only when sitting, or wearing it only at night do not sufficiently address the need for balance between immobilization of the shoulder and promoting movement in the distal extremities. Complete immobility can lead to more serious issues like stiffness and lack of coordination in the forearm and hand, which are crucial for daily activities and rehabilitation post-surgery. Therefore, allowing for some degree of movement in the forearm and hand, while still ensuring that the shoulder and humerus remain protected, is a key instruction for clients using a shoulder immobilizer following surgery.
