Answer to Question 1
ANS: A, C, D
Clinical manifestations of compartment syndrome are caused by several physiologic changes. Edema is caused by increased capillary permeability, release of histamine, decreased tissue perfusion, and vasodilation. Unequal pulses are caused by an increased production of lactic acid. Cyanosis is caused by anaerobic metabolism. Pallor is caused by decreased oxygen to tissues, and tingling is caused by increased tissue pressure.
Answer to Question 2
ANS: A, B, D
Postoperative care for a client who has ORIF of the hip includes elevating the client's heels off the bed and re-positioning every 2 hours to prevent pressure and skin breakdown. It also includes ambulating the client on the first postoperative day, and using pillows or an abduction pillow to prevent subluxation of the hip. The nurse should teach the client to use the patient-controlled analgesia pump, but the nurse should never push the button for the client.
