The patient elevated their shoulders during inspiration.

Which procedure is most appropriate when performing a cervical spine exam for suspected trauma on a patient on a backboard with the head immobilized?

Obtain a cross-table lateral for the physician prior to further imaging

An 82-year-old female patient is transported to the x-ray department for an examination of the right hip.

abduction

What should be done to correct positioning on an anteroposterior (AP) elbow with lateral rotation, when the radial head is slightly superimposed over the proximal ulna on the first effort?

The elbow joint should be rotated laterally.
