A client with a left arm fracture complains of severe diffuse pain that is unrelieved by pain medication. On further assessment, the nurse notes that the client experiences increased pain during passive motion compared with active motion of the left arm. Based on these assessment findings, which action should the nurse take first?

The correct answer is to contact the health care provider. The client with early acute compartment syndrome typically complains of severe diffuse pain that is unrelieved by pain medication. Additionally, the affected client experiences greater pain during passive motion compared to active motion. In this situation, it is crucial to notify the health care provider immediately for further evaluation and intervention. Contacting the health care provider is essential to ensure timely diagnosis and appropriate management of the condition. Checking for more pain medication, encouraging active range of motion exercises, or repositioning the client may not address the underlying issue of acute compartment syndrome and could delay necessary interventions. Therefore, the priority action should be to involve the healthcare provider for prompt assessment and treatment.
