In assessing a client with severe osteoarthritis using a goniometer, which measurement is the nurse primarily looking for?

The primary measurement a nurse is looking for when assessing a client with severe osteoarthritis using a goniometer is the degree of flexion and extension of the client's knee joint. The goniometer is a specific instrument used to measure the range of motion in joints, which is particularly relevant in osteoarthritis. In this condition, the integrity and movement capabilities of the joint can be significantly impaired due to pain, swelling, and degeneration of cartilage. Measuring the flexion and extension allows the nurse to assess the degree of limitation in movement, which can guide treatment plans and monitor progression or improvement of the condition.

This focus on joint movement is crucial because it provides insight into the functional capabilities of the knee and can help identify potential needs for physical therapy, surgical interventions, or modifications in activities to enhance the client’s quality of life.
