The orthopedic office nurse provides care to a patient who sustained an injury after a fall on an icy patch of sidewalk a year ago. The patient states. "I still cannot move my knee well because of the pain and swelling." Which diagnostic test should the nurse anticipate will be prescribed by the health care provider?

A. Ultrasound: Useful for assessing soft tissue injuries (e.g., tendon tears, effusions), but not the best for chronic joint pain and movement restriction; limited for internal joint structure visualization. B. Bone Biopsy: Performed when malignancy or infection of the bone is suspected. Not indicated in this chronic post-injury scenario. C. Arthroscopy: A minimally invasive procedure that allows direct visualization and possible treatment of intra-articular knee problems like cartilage damage or meniscal tears-common causes of chronic pain/swelling. D. Serum Alkaline Phosphatase Test: A lab test used to evaluate bone metabolism, often elevated in bone diseases (e.g., Paget’s disease), but not diagnostic for chronic joint injury or swelling.
