Question

william has been suffering from pain in his knee for some time. his doctor intends to inject the knee joint with a mix of steroid and pain medication. this is part of a procedure called: (1 point) radiography deep tendon reflexes. arthrography. electromyography

Explanation:

• Radiography: It is an imaging technique using X - rays to visualize bones, not a procedure involving injection of steroid and pain medication.
• Deep tendon reflexes: This is a neurological examination method (e.g., tapping the patellar tendon), not related to injection.
• Arthrography: In arthrography, a contrast medium (and sometimes medications like steroids for therapeutic purposes) is injected into a joint (such as the knee joint) to visualize the joint structures (e.g., ligaments, cartilage) and also can be used for therapeutic pain - relief when combined with pain medications.
• Electromyography: It is a test to evaluate muscle and nerve function by measuring electrical activity of muscles, not involving joint injection.

Answer:

arthrography.
