Vertical, low position, below the transpyloric portion
Almost horizontal & high, well above the umbilicus
To the far left in the hepatic flexure
To the far right in the sphenic flexure

Correct Answer

A. Vertical, low position, below the transpyloric portion

3.

the digestive system consists of: the accessory glands & the ______________

Correct Answer
alimentary canal
alimentary canal
canal

Explanation
The digestive system consists of two main components: the accessory glands and the alimentary canal. The accessory glands include organs such as the salivary glands, liver, and pancreas, which secrete digestive enzymes and substances that aid in the breakdown of food. The alimentary canal, also known as the gastrointestinal tract, is a long tube that runs from the mouth to the anus and is responsible for the digestion and absorption of nutrients. The term "canal" is a general term that refers to a passageway or tube, but in the context of the digestive system, it specifically refers to the alimentary canal.

which one is not a part of the accessory gland?

Salivary glands
Liver
Gallbladder
Pharynx

Correct Answer

A. Pharynx

Explanation

The pharynx is not a part of the accessory gland. The salivary glands, liver, and gallbladder are all considered accessory glands as they assist in the digestive process by producing and releasing substances such as saliva, bile, and enzymes. The pharynx, on the other hand, is a part of the digestive and respiratory systems, responsible for swallowing and directing food and air to their respective passages.

what secretes digestive enzymes into the alimentary canal?

Liver & pancreas
Gallbladder
Salivary glands
All of the above

Correct Answer

A. All of the above

Explanation

The correct answer is "all of the above." The liver secretes bile, which aids in the digestion and absorption of fats. The pancreas secretes pancreatic enzymes, such as amylase, lipase, and protease, which help break down carbohydrates, fats, and proteins respectively. The gallbladder stores and releases bile produced by the liver. The salivary glands secrete saliva, which contains enzymes like amylase that initiate the digestion of carbohydrates in the mouth. Therefore, all of these organs secrete digestive enzymes into the alimentary canal.

THE MOUTH, pHARYNX, & ESOpHAGUS, STOMACH, ETC ARE ALL PARTS OF WHAT

FIBROUS LAYER
LARGE INTESTINE
SMALL INTESTINE
ALIMENTARY CANAL

Correct Answer

A. ALIMENTARY CANAL

Explanation

The mouth, pharynx, esophagus, stomach, etc. are all parts of the alimentary canal. The alimentary canal is a long, hollow tube that runs from the mouth to the anus and is responsible for the digestion and absorption of food. It includes various organs such as the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. These organs work together to break down food into smaller molecules, absorb nutrients, and eliminate waste. The term "alimentary canal" is used to refer to the entire digestive system as a whole.

WHICH ONE MOVES QUICKER?

IODINATED SOLUTION
BARIUM SULFATE SUSPENSIONS

Correct Answer

A. IODINATED SOLUTION

Explanation

Iodinated solution moves quicker than barium sulfate suspensions. This is because iodinated solution has lower density and viscosity compared to barium sulfate suspensions. The lower density allows the iodinated solution to move more easily through the body, while the lower viscosity reduces resistance to flow. As a result, the iodinated solution can travel faster and reach its target area more quickly than the barium sulfate suspensions.

HOW LONG DOES IT TAKE 4 AN IODINATED SOL TO CLEAR THE stomach?

4 hours
15-30 min
3 hours
1-2 hrs

Correct Answer

A. 1-2 hrs

Explanation

The correct answer is 1-2 hrs. This means that it takes approximately 1-2 hours for an iodinated sol to clear the stomach.

what contrast is used for UGI STUDY?

Air
Barium sulfate
Crystal
Water iodinate sol

Correct Answer

A. Barium sulfate

Explanation

Barium sulfate is used as a contrast agent for UGI (Upper Gastrointestinal) studies. It is a white, chalky substance that is not absorbed by the body. When ingested, it coats the lining of the esophagus, stomach, and small intestine, allowing these structures to be clearly visible on X-rays. Barium sulfate provides a high contrast between the gastrointestinal tract and surrounding tissues, making it easier for doctors to detect abnormalities or diagnose conditions such as ulcers, tumors, or blockages.

for the ESOpHAGUS- rao how much is the pt obliqued?

35-40
45
25-30

Correct Answer

A. 35-40

Explanation

The correct answer is 35-40. This range indicates the degree to which the patient is obliqued during the examination of the esophagus using the rao position. Obliquing the patient at this angle allows for better visualization and assessment of the esophagus.

where do you center the elevated side on rao esophagus?

2 lateral to midsdag plane
2 superior to midsag plane
1.5-2 lateral to midsag plane

Correct Answer

A. 2 lateral to midsdag plane

Explanation

The correct answer is 2 lateral to midsagittal plane. This means that the elevated side of the rao esophagus is centered 2 lateral to the midsagittal plane. This positioning allows for a clear and accurate view of the esophagus during imaging or procedures.

12.

in the lpo position the side being examined is?

Up
Down

Correct Answer

A. Up

Explanation

The correct answer is "up." In the LPO (left posterior oblique) position, the side being examined is the upper side. This position allows for better visualization of the left kidney and surrounding structures by angling the X-ray beam from the patient's back to the front. The LPO position is commonly used in radiology to assess the left kidney and diagnose any abnormalities or conditions affecting it.

where is the cr 4 LATERAL ESOpHAGUS?

PERP TO THE MIDPT OF T7
2-2.5
PERP TO THE MIDPT OF T5-T6

Correct Answer

A. PERP TO THE MIDPT OF T5-T6

Explanation

The correct answer is "PERP TO THE MIDPT OF T5-T6". This means that the cr 4 (cranial 4) lateral esophagus is located perpendicular to the midpoint of the T5-T6 vertebrae.
