A client who has partial and full thickness burns of both hands and arms calls the nurse to report his right hand is becoming increasingly painful and tingling.  The nurse observes the right hand is now darker in color and cooler to touch than the left hand.  The nurse notes the client had received intravenous pain medication one hour ago.  The nurse notified the primary care provider about this development.  What is the next appropriate action by the nurse?
