Nokea
A client is scheduled to have an x-ray examination of the shoulder in which the synovial fluid will be aspirated and sent to the laboratory for analysis. This will be followed by administration of a contrast medium and x-rays. The nurse understands that the client will be undergoing which test(s)?
Correct Answer: B,C
Rationale: An arthrogram is a radiographic examination of a joint usually the knee or shoulder. The health care provider first injects a local anesthetic and then inserts a needle into the joint space. Fluoroscopy may be used to verify correct placement of the needle. The synovial fluid in the joint is aspirated and sent to the laboratory for analysis. A contrast medium is then injected, and x-ray films are taken. Arthroscopy is the internal inspection of a joint using an arthroscope. Arthrocentesis is the aspiration of synovial fluid. The client involves local anesthesia just before this procedure. The health care provider inserts a large needle into the joint and removes the fluid. This can be done during an arthrogram or arthroscopy. Bone densitometry estimates bone density using radiography or advanced radiographic techniques. Electromyography tests the electrical potential of the muscles and nerves leading to the muscles.
