how do you administer a barium for small intestine
Correct Answer
D. All of above
Explanation
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.
2.
what is part of the preferred prep for small intestine?
Correct Answer
A. Soft or low residue diet 2 days before
Explanation
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.
3.
if the exam can't be delayed, what are the alternate preps for the small?
Correct Answer
D. All of above
Explanation
The correct answer is "all of above." This means that all of the mentioned alternatives are valid preparations for the small exam if it cannot be delayed. This includes withholding food/fluid for the evening meal before the exam, withholding food/fluid the morning of the exam, and using a cleansing enema.
4.
what radiograph is usually taken b4 a small bowel series?
Correct Answer
B. Kub
Explanation
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.
5.
Which of the following radiographic techniques is most commonly used to examine the small and large intestines?
Correct Answer
B. Barium Enema
Explanation
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.
6.
The pt's bladder should be emptied b4 a procedure 4 small to avoid displacing the:
Correct Answer
A. Ileum
Explanation
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.
7.
what is the supine useful 4 with small series
Correct Answer
B. Prevent overlapping of loops
Explanation
The supine position is useful for preventing overlapping of loops in small series imaging. This position helps to separate and visualize the duodenum and jejunum more clearly by reducing the overlapping of intestinal loops. This allows for better visualization of the barium-filled stomach and improves the overall imaging quality.
8.
for the sthenic, where do you center ir w/in 30 min of contrast on small?
Correct Answer
C. At the level of L2
Explanation
The correct answer is to center the IR at the level of L2. This means that when performing a scan for the sthenic patient, the imaging receptor should be positioned at the level of the second lumbar vertebra. This ensures that the area of interest is captured accurately within the image.
9.
where do you center IR for delayed small radiographs?
Correct Answer
A. Perp. to the IC
Explanation
The correct answer is "perp. to the IC." This means that the infrared (IR) should be centered perpendicular to the image receptor (IC) for delayed small radiographs.
10.
where does the barium reach on PA small?
Correct Answer
C. Ileocecal valve
Explanation
The barium reaches the ileocecal valve on a PA small.
11.
when is exam completed on pa small?
Correct Answer
D. When barium reaches cecum
Explanation
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.
12.
how do u know when the TUBE is inserted CORRECTLY?
Correct Answer
UNDER FLUORO
FLUOROSCOPY
UNDER FLUROSCOPY
FLUORO
Explanation
The correct answer options "UNDER FLUORO", "FLUOROSCOPY", "UNDER FLUROSCOPY", and "FLUORO" all refer to the same method of determining if a tube is inserted correctly, which is using fluoroscopy. Fluoroscopy is a medical imaging technique that uses X-rays to obtain real-time moving images of the inside of the body. By using fluoroscopy, medical professionals can visualize the tube being inserted and ensure that it is in the correct position.
13.
ON a right lateral DECUB, what is in the RIGHT colic FLEXURE
Correct Answer
B. BARIUM
Explanation
On a right lateral decubitus position, the right colic flexure refers to the bend in the colon where the ascending colon transitions into the transverse colon. The presence of barium in the right colic flexure indicates that barium, a contrast agent commonly used in imaging tests such as barium enemas, has reached this specific area of the colon. This answer suggests that the barium has successfully passed through the ascending colon and is now present in the right colic flexure.
14.
ON a right lateral DECUB, what is in the LEFT colic FLEXURE
Correct Answer
A. Air
Explanation
In a right lateral decubitus position, the left colic flexure refers to the bend or curve in the colon located on the left side of the body. The presence of air in the left colic flexure indicates that there is gas present in that specific area of the colon. This could be a normal finding or could indicate the presence of gas trapped in that part of the colon, potentially due to a blockage or other gastrointestinal issue.
15.
where does the barium sit on a LEFT LATERAL DECUB
Correct Answer(s)
A. LEFT COLIC
D. DESCENDING COLON
Explanation
In a left lateral decubitus position, the patient is lying on their left side. The barium, which is a contrast material used in medical imaging, will settle in the lowest part of the colon due to gravity. In this position, the lowest part of the colon is the descending colon, which is located on the left side of the body. Therefore, the correct answer is "LEFT COLIC, DESCENDING COLON."
16.
WHERE DOES BARIUM SIT IN A VENTRAL DECUB LEFT LATERAL
Correct Answer(s)
A. TRANSVERSE
B. ASCENDING
Explanation
Barium is a contrast agent used in medical imaging to visualize the gastrointestinal tract. In a ventral decubitus position, the patient lies on their back with the X-ray machine positioned above them. In this position, the barium would be located in the transverse and ascending portions of the colon. The transverse colon runs horizontally across the abdomen, while the ascending colon travels up the right side of the abdomen. Therefore, the correct answer is "TRANSVERSE, ASCENDING."
17.
THE LATERAL PROJ OF LARGE INTES. BEST DEMONSTRATES:
Correct Answer(s)
C. RECTUM
D. DISTAL SIGMOID
Explanation
The correct answer is RECTUM, DISTAL SIGMOID. The lateral projection of the large intestine is a radiographic technique used to visualize specific parts of the colon. In this case, the rectum and distal sigmoid are the areas of interest. This projection allows for better visualization and evaluation of abnormalities or pathologies in these regions.
18.
WHICH POSITION less superimposes the right COLIC FLEC
Correct Answer(s)
A. PA OBL RAO
C. PA OBL LPO
Explanation
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.
19.
WHICH POSITION less superimposes the LEFT COLIC FLEC
Correct Answer
B. PA OBL LAO
Explanation
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.
20.
what is the vERMIFORM APPENDIX ATTACHED TO?
Correct Answer
CECUM
posteromedial side of cecum
Explanation
The vermiform appendix is attached to the cecum, specifically on the posteromedial side. The cecum is the pouch-like structure that forms the beginning of the large intestine. The appendix is a small, finger-like projection that extends from the cecum.
21.
how long does it take an IODINATED SOL to clear the stomach?
Correct Answer
C. 1-2 hrs
Explanation
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.

reach the COLON
Correct Answer
B. 4 hrs
Explanation
The correct answer is 4 hrs. This is because it takes approximately 4 hours for an iodinated sol to reach the colon.
23.
how long does it take a barium to reach the ileocecal valve?
Correct Answer
B. 2-3 hrs
Explanation
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.
24.
how long does it take a barium to reach the last ileocecal valve?
Correct Answer
4-5 hrs
4-5 hours
4-5
Explanation
The correct answer is 4-5 hrs, 4-5 hours, 4-5. The question is asking about the time it takes for barium to reach the last ileocecal valve. The answer options all indicate a time frame of 4-5 hours, which suggests that it takes approximately 4-5 hours for the barium to reach the last ileocecal valve.
