There is a correction to the Human Machine Skeletal and Muscular System Study Guides (2&3 and 4&5). The bone that is fractured in the sample x-ray question is the radius not the ulna. The current study guides on the website contain this correction.
Q: Will the students need to identify any injury besides fractures on x-rays? On the sample question in the study guide, the answer to where the injury is located is ‘ulna.’ The ulna appears to be dislocated and the radius fractured.
A: Students will only need to identify fractures of the type listed in the study guide on an x-ray. They should be familiar with the other types of injuries listed in the study guide (sprains, ligament tears, strains etc.) and may receive a question about them in another context (image, description, etc.). Students do not need to identify a dislocation. Thank you for pointing out the error in the study guide. The bone that is fractured in the x-ray sample in the study guide is the radius not the ulna.
