Answer:
The correct statement is: Russell's traction uses a sling under the knee to treat a fracture of the femur.
Step-by-step explanation:
Russell's traction is a type of traction that is used to treat fractures of the femur (thigh bone) by pulling on the leg with a sling placed under the knee. This type of traction is used to keep the leg in a straight position, which can help to realign the fracture and reduce pain. It does not use a cervical halter, pelvic girdle belt, or skeletal pins for any purpose. Therefore, the nurse should make the following statement to reinforce teaching about Russell's traction: "Russell's traction uses a sling under the knee to treat a fracture of the femur."
