study above the diaphragm? - ✔✔ribs 1 through 10

expiration. - ✔✔False

adjacent to the spine? - ✔✔LAO

of the sternum? - ✔✔blurring of the lung markings and ribs
✔✔What is the best method to control voluntary motion during abdominal radiography?
- ✔✔Short exposure time
✔✔What type of respiration should be employed during the exposure for the
anteroposterior (AP) kidneys, ureter, and bladder (KUB) abdomen projection? -
✔✔Expiration
, ✔✔To ensure that the inferior margin of the abdomen is included on a KUB radiograph,
the technologist should palpate the: - ✔✔greater trochanter or symphysis pubis.
✔✔The preferred imaging modality for examining the gallbladder is: - ✔✔sonography.
