• Due to the time spent in bed and inactivity, the patient is at high risk for the development of a deep vein thrombosis (DVT). Pain in the calf, redness or heat, and swelling in the affected extremity are signs of a DVT.

• Incorrect: Administering pain medication would treat the pain, but would not help determine the source of the pain.
