Which 3 projections usually comprise the acute adbomen series for ambulatory patients?	Supine KUB, AP upright abdomen, PA chest
Why is it desirable to include the diaphragm in the upright abdominal x-ray?	To demonstrate free air in the abs
Which projection should be used to demonstrate free air within the ab cavity when the patient is unable to stand for an upright ab x-ray?	AP projection, left lateral decubitus position
Which projection does not demonstrate free air levels within the abdomen?	AP projection with the patient supine
What is the major advantage of the PA projection of the abdomen over the AP projection of the abdomen?	PA projection reduces exposure dose to the gonads.
Which x-ray position of the abs requires the patient to be supine with the CR directed to a lateral side of the patient, entering slightly anterior to the MCP?	Dorsal decubitus
For the lateral projection with the patient placed in the dorsal decubitus position, where should the CR enter the patient?	2 inches anterior to the MCP and 2 inches above the level of the iliac crests.
Which structures should be examined to see whether the patient was rotated for a lateral projection of the abdomen?	Pelvis and lumbar vertebrae
