A client is admitted to the emergency department with a full-thickness burn to the right arm. Upon assessment, the arm is edematous, the fingers are mottled, and the radial pulse is now absent. The client states that the pain is 8/10. What is the priority action the nurse should take?

Choice A reason: Instructing the client to exercise the fingers and wrist is not the immediate priority. While maintaining mobility is important in burn care, the absence of a radial pulse indicates a potential vascular compromise that needs urgent attention.Choice B reason: Calling the healthcare provider to report the loss of the radial pulse is the correct and immediate action. The absence of a radial pulse suggests that the edema is causing compartment syndrome, which can lead to tissue ischemia and necrosis if not promptly treated. This is a medical emergency requiring immediate intervention, possibly including a fasciotomy to relieve pressure.Choice C reason: Continuing to assess the arm every hour for additional changes is important, but it is not the immediate priority. The absence of a radial pulse indicates a critical issue that needs immediate reporting and intervention, rather than waiting for further changes.Choice D reason: Administering morphine IV can help manage the client's pain, which is significant at 8/10. However, it does not address the underlying issue of the absent radial pulse and potential compartment syndrome. Pain management is important but secondary to resolving the vascular compromise.
