Why would barium be contraindicated (pick two)

• Allergy

• Pregnancy

• Perforation

• Large Bowel obstruction

Answer explanation

Barium would be contraindicated if there was a suspected perforation or a large bowel obstruction. Pregnant women can consume barium and barium is rarely contraindicated due to an allergy.

Which part of the stomach is most posterior?

• Fundus

• Body

• Pylorus

Answer explanation

The stomach is the most posterior portion of the stomach, if we are laying down because of it's location, it would fill with barium and erect it would fill with air.

The body is anterior and inferior to the fundus

The pylorus is posterior to the body

If the patient is in AP (supine) position where would barium be mainly located?

• Fundus

• Body

• Pylorus

Answer explanation

 If the patient is in an AP position, the fundus would be posterior to the body and would fill with contrast. The body would be filled with air to see the rugae and because the pylorus is also posterior, there may be some barium in there as well.

If the patient is prone (PA) where would the barium be located?

• Fundus

• ileum

• Pylorus

• Body and possible pylorus

Answer explanation

If the patient is prone, then the stomach would be compressed and there would be a minimal amount of air located in the fundus. The body and possibly the pylorus will have barium. The body definitely because it is more anterior and would pool in there.

If the patient is in LPO where would the barium be located?

• Fundus

• Body

• Pylorus

• Body & pylorus

Answer explanation

If the patient is LPO then the contrast would mainly be located in the fundus. Think again about the orientation of the stomach. The fundus is the most posterior portion, if they are laying on their back and rotated toward that left side then the contrast will stay in the fundus.

If the patient is in an RAO position, where would the barium be located?

• Fundus

• Body

• Pylorus

• Lower body & pylorus

Answer explanation

In an RAO, air would be in the fundus and barium would be in the body and pylorus.

Where would barium be located in a RT. Lateral

• Fundus

• Body

• Body& pylorus

• Pylorus

Answer explanation

In a right lateral, barium would be located in the body and pylorus. Air would be located in the fundus.

Besides the stomach, what other landmark can I use to determine the projection?

• ribs

• diaphragm

• spine

• just guess

Answer explanation

Look at the spine when doing process of elimination for the image. An AP- spinous process will be in the center of the spine. LPO/RAO- should see scotty dogs or some elongation from the ribs. Right lateral- vertebral bodies and intervertebral disk space will be seen.

What is the final portion of the UGI system

• duodenum

• ileum

• jejunum

• ileocecal valve

Answer explanation

The final portion of the UGI system is the duodenum. The duodenum is the first segment of the small intestine. It is the shortest, widest, and most fixed portion and has a c-shaped. It is often called the romance of the abdomen because the head of the pancreas sits in the c-loop of the duodenum
