Ans: B
Feedback: Exercise of the extremities includes extension and flexion of the knee and hip joints (similar to bicycle riding while lying on the side) unless contraindicated by type of surgical procedure (eg, hip replacement). When the patient does leg exercises postoperatively, circulation is increased, which helps to prevent blood clots from forming. Options A, C, and D are incorrect; leg exercises do not increase the patient's appetite, prevent pressure sores to the sacrum, or increase the patient's level of consciousness.
