Which of the following is the primary risk factor for the development of osteoarthritis?

X-ray imaging is commonly used to diagnose osteoarthritis. It can visualize joint space narrowing, bone spurs, and other changes associated with the disease.

a. MRI is more commonly used to assess soft tissue structures and is not the first-line imaging modality for osteoarthritis.
b. CT scan is not typically used for diagnosing osteoarthritis due to its higher radiation exposure compared to X-ray.
d. Ultrasound is not commonly used for diagnosing osteoarthritis; it is more useful for soft tissue assessment.

Using a walker is an appropriate choice for a client with osteoarthritis who needs support and stability while moving around the house. It helps distribute weight evenly and reduces stress on the affected joints. Using a cane on the same side as the affected knee can provide some support but may not be as effective as a walker. Placing the crutches under the arms is not a correct technique for using crutches, as they should be positioned in the hand grips for proper support. Using a wheelchair for all daily activities may not be necessary for a client with osteoarthritis, as it may lead to decreased mobility and muscle weakness.

a. "I will use a cane on the same side as my affected knee." Using a cane on the same side as the affected knee may not provide sufficient support and stability for the client.
c. "I will place the crutches under my arms for support." Placing the crutches under the arms is not a correct technique for using crutches, as they should be positioned in the hand grips for proper support.
d. "I will use a wheelchair for all my daily activities." Using a wheelchair for all daily activities may not be necessary for a client with osteoarthritis, as it may lead to decreased mobility and muscle weakness.
