The client who is 1 day postoperative from a total hip replacement is prescribed to perform quadriceps-setting exercises several times daily. Which statement by the nurse indicates cor-rect application of this exercise?
A. "Straighten your legs and push the back of your knees into the mattress."
B. "Straighten your legs and bring each leg separately off the mattress 6 inches.
C. "Raise each leg 10 inches off the bed, keep it straight, and make circles with your ankle."
D. "Bend each leg separately at the knee, then rapidly point your toes downward then upward."
A
The quadriceps are the four large muscles on the front of the thigh. When they contract, they flex the hip and the knee. Many clients with hip or knee joint problems have shortened quadriceps muscles from staying in a flexed position. These powerful muscles need to be stretched or "set" for the person to have better mobility with the new joint. Straightening the leg as much as possi-ble by attempting to push the back of the knees into the mattress causes stretching and straigh-tening of this muscle group.
