-
Ultrasound
-
Barium Enema
-
Magnetic Resonance Imaging (MRI)
-
Computed Tomography (CT) Scan
Correct Answer
A. Barium EnemaExplanation
While several imaging techniques can be used to examine the small and large intestines, a barium enema is a specific radiographic technique commonly used for the large intestine. It involves the introduction of a barium sulfate contrast material into the colon through the rectum, followed by X-rays to visualize the colon and rectum. This technique helps in detecting abnormalities such as polyps, tumors, and diverticula.Rate this question:

what radiograph is usually taken b4 a small bowel series?
-
Rectum
-
Kub
-
Lateral rectum
-
Rao stomach
Correct Answer
A. KubExplanation
A KUB (Kidneys, Ureters, Bladder) radiograph is usually taken before a small bowel series. This is because a KUB can provide a baseline image of the abdomen and help identify any abnormalities or obstructions in the gastrointestinal tract. It can also help determine the positioning and size of the small bowel loops before the series is performed.Rate this question:

-
PA OBL RAO
-
PA OBL LAO
-
LATERAL PROJ
-
PA AXIAL
Correct Answer
A. PA OBL LAOExplanation
The position that less superimposes the left colic flexure is PA OBL LAO. This position allows for a better visualization of the left colic flexure by angling the x-ray beam in an oblique direction from a posterior to anterior direction, with the patient in a left anterior oblique position. This helps to separate the structures and reduce superimposition, allowing for a clearer image of the left colic flexure.Rate this question:

how do you administer a barium for small intestine
-
Mouth
-
Reflux filling
-
Enteroclysis
-
All of above
Correct Answer
A. All of aboveExplanation
The correct answer is "all of above". This means that barium can be administered for small intestine examination through the mouth, reflux filling, and enteroclysis. These are different methods of administering barium depending on the specific requirements of the examination. Administering barium through the mouth is the most common method, where the patient drinks a barium solution. Reflux filling involves using a catheter to introduce barium into the small intestine through the stomach. Enteroclysis is a more invasive procedure where barium is directly introduced into the small intestine through a tube inserted through the nose or mouth.Rate this question:

-
3-4 hrs
-
15-30 min
-
1-2 hrs
-
4 hrs
Correct Answer
A. 1-2 hrsExplanation
The correct answer is 1-2 hrs. Iodinated sol is a solution that contains iodine, which is commonly used in medical imaging procedures such as CT scans. When ingested, it takes about 1-2 hours for the iodinated sol to clear the stomach. During this time, the sol is broken down and absorbed by the body, allowing for clear imaging of the stomach and surrounding organs.Rate this question:

what is part of the preferred prep for small intestine?
-
Soft or low residue diet 2 days before
-
Nothing to eat 24 hrs before exam
-
By cleansing enema only
-
All of the above
Correct Answer
A. Soft or low residue diet 2 days beforeExplanation
The preferred prep for the small intestine includes following a soft or low residue diet for 2 days before the exam. This is because a soft or low residue diet helps to reduce the amount of undigested food and residue in the intestines, making it easier for the doctor to visualize the small intestine during the exam. This prep method allows for a clearer and more accurate examination of the small intestine.Rate this question:

how long does it take a barium to reach the ileocecal valve?
-
3-4 hrs
-
2-3 hrs
-
4-5 hrs
Correct Answer
A. 2-3 hrsExplanation
Barium is a contrast material commonly used in medical imaging procedures to visualize the gastrointestinal tract. After ingestion, it takes approximately 2-3 hours for barium to reach the ileocecal valve, which is the junction between the small intestine and the large intestine. This transit time allows the barium to pass through the stomach, duodenum, jejunum, and ileum before reaching the ileocecal valve. The timing may vary slightly depending on individual factors such as digestion and motility.Rate this question:

The pt's bladder should be emptied b4 a procedure 4 small to avoid displacing the:
-
Ileum
-
Cecum
-
Right flecure
-
Ascending colon
Correct Answer
A. IleumExplanation
The correct answer is ileum because emptying the bladder before a procedure prevents it from displacing the surrounding organs. The ileum is a part of the small intestine and is located near the bladder. If the bladder is full during a procedure, it can push against the ileum and potentially cause displacement or other complications. Therefore, emptying the bladder beforehand is necessary to ensure the safety and accuracy of the procedure.Rate this question:

when is exam completed on pa small?
-
When barium reaches ileocecal valve
-
When barium fills stomach
-
When barium lines colon
-
When barium reaches cecum
Correct Answer
A. When barium reaches cecumExplanation
The completion of the exam on pa small occurs when barium reaches the cecum. This indicates that the barium has successfully passed through the small intestine and has reached the beginning of the large intestine. The cecum is the first part of the large intestine, located in the lower right abdomen. Once the barium reaches this point, it signifies that the exam has covered the entire small intestine and is ready to proceed to the next stage of the procedure.Rate this question:

Correct Answer(s)
A. PA OBL RAO
A. PA OBL LPOExplanation
The positions PA OBL RAO and PA OBL LPO are the ones that less superimpose the right colic flexure. These positions involve an oblique angle of the patient's body, which helps to separate and visualize the right colic flexure more clearly. PA OBL RAO refers to a posterior-anterior oblique position with the patient rotated to the right, while PA OBL LPO refers to a posterior-anterior oblique position with the patient rotated to the left. These positions allow for better visualization of the right colic flexure by minimizing superimposition with other structures.Rate this question:
