Exhibits A nurse is caring for a child who is 2 hr postoperative. Which of the following actions should the nurse take first? (Click the "Exhibit" button for additional information about the client. There are three tabs that contain separate categories of data.)

A. Assessing the child's pain level is important but may not be the first priority postoperatively, especially if there are signs of compromised circulation. B. Rechecking the child's temperature is important but may not be the first priority postoperatively unless there are specific concerns related to temperature regulation. C. Determining the child's sedation level is important for monitoring but may not be the first priority unless there are signs of respiratory compromise or other urgent concerns. D. Comparing the child's pedal pulses is crucial in this situation as the child has undergone surgical procedures on the lower extremity, and changes in pedal pulses could indicate compromised circulation, which requires immediate attention to prevent complications such as compartment syndrome.
