Which diagnostic tools would the nurse identify as the most useful in evaluating undiagnosed skeletal and joint conditions?
1. X-Ray
2. MRI
3. CT scan
4. Myelogram
Answer: 1
X-ray films are very useful diagnostic tools and can be used to identify joint disruption, bone deformities, calcifications, bone deterioration, and fractures and are used to measure bone density. MRI uses a strong magnetic field and radio waves to diagnose conditions (three-dimensional view), especially problems in the joints and soft tissue injuries. A CT scan can be used to identify injuries of soft tissue, ligaments, tendons, and muscles. Obtaining a myelogram is an invasive procedure used to evaluate abnormalities of the spinal canal and cord.
