A Client Who Has Undergone Repair of the Anterior Cruciate

A client who has undergone repair of the anterior cruciate ligament complains that the use of the continuous passive motion (CPM) machine causes pain and asks how long he is expected to use the machine. The nurse's most appropriate response would be

A) "I will give you pain medication to make you comfortable, since you should use the machine at least 8 hours out of 24."
B) "Try using the machine for 1 hour of every 4 hours, and see if that schedule reduces your discomfort."
C) "You do not have to use the machine for the next few days. You can resume after the pain subsides."
D) "You should use the machine continuously. I will ask the physician to increase your dose of analgesics."
