Question

After a knee replacement, an 87-year-old patient rejects the use of the continuous passive motion (CPM) machine, saying, I did not march when I was a child, and I am not marching now. What benefits of CPM should the nurse point out to encourage patient use?

a. Decrease in pain
b. Increase in circulation in the new joint
c. Increase in leg strength
d. Increase in flexibility for the new joint

Answer 1

The nurse should explain the benefits of using a continuous passive motion (CPM) machine after knee replacement surgery, including a decrease in pain, increase in circulation in the new joint, and increase in flexibility for the new joint.

Step-by-step explanation:

The nurse should point out several benefits of using the continuous passive motion (CPM) machine after a knee replacement:

1. Decrease in pain: CPM helps to reduce pain and discomfort by promoting blood circulation and preventing stiffness in the joint.
2. Increase in circulation in the new joint: The repetitive motion of CPM improves blood flow to the new joint, promoting healing and reducing the risk of blood clots.
3. Increase in flexibility for the new joint: Using CPM helps to prevent scar tissue formation and increases the range of motion in the new joint.
