Obstruction or infection may be indicated if the air is seen in the _________ on a radiograph of the abdomen.
- A.
Small intestine
- B.
Fundus of the stomach
- C.
Colon
- D.
Rectum
Correct Answer
C. ColonExplanation
If air is seen in the colon on a radiograph of the abdomen, it may indicate obstruction or infection. The presence of air in the colon suggests that there is an abnormal accumulation of gas in this part of the digestive system. This could be caused by a blockage or narrowing of the colon, which prevents the normal passage of gas and stool. Alternatively, it could be a sign of infection, such as diverticulitis or colitis, which can cause inflammation and gas buildup in the colon.Rate this question:

These are purposes of one hour delayed film in Upper GI Series examination, except to what extent?
- A.
To demonstrate the stomach empty.
- B.
To demonstrate the presence of Ascaris.
- C.
To determine stomach habitus.
- D.
To know how much barium was left.
Correct Answer
C. To determine stomach habitus.Explanation
The purpose of a one-hour delayed film in an Upper GI Series examination is to determine how much barium was left in the stomach. This allows the radiologist to assess the rate at which the stomach empties and to evaluate any abnormalities or conditions that may affect gastric motility. Demonstrating the presence of Ascaris and determining stomach habitus are not specific purposes of the one-hour delayed film.Rate this question:

Radiographs with the patient in the decubitus position are produced following an air-contrast barium enema examination. The radiographer fails to properly label the radiograph. To identify the right lateral decubitus image, the radiographer should see:
- A.
Air in the lateral descending colon and medial ascending colon.
- B.
Barium in the lateral descending colon medial descending colon.
- C.
Air in the descending colon and barium in the stomach.
- D.
Air in the stomach and barium in the lateral descending colon
Correct Answer
A. Air in the lateral descending colon and medial ascending colon.Explanation
The radiographer should see air in the lateral descending colon and medial ascending colon in order to identify the right lateral decubitus image. This is because the decubitus position allows air to rise and fluid (such as barium) to settle. In this position, the lateral descending colon should contain air, while the medial ascending colon should also contain air due to the change in patient position. This combination of air in the lateral descending colon and medial ascending colon is characteristic of the right lateral decubitus image.Rate this question:

A scout film radiograph on a large hypersthenic patient reveals that the entire abdomen is not included on the 14x17 inches IR. What can be done to correct this on the repeat radiograph?
- A.
Use two cassettes placed lengthwise.
- B.
Use two cassettes placed crosswise.
- C.
Expose during deep inspiration.
- D.
Perform Scout film with a patient in the erect position.
Correct Answer
B. Use two cassettes placed crosswise.Explanation
To correct the issue of the entire abdomen not being included on the 14x17 inches IR, two cassettes can be used and placed crosswise. This will provide a larger imaging area and ensure that the entire abdomen is captured in the radiograph.Rate this question:

The best way to control voluntary motion is
- A.
Immobilization of the part.
- B.
Careful explanation of the procedure.
- C.
Short exposure time.
- D.
Physical restraint.
Correct Answer
B. Careful explanation of the procedure.Explanation
Careful explanation of the procedure is the best way to control voluntary motion because it helps the patient understand what is expected of them and reduces anxiety or fear that may cause involuntary movements. By providing clear instructions and information about the procedure, the patient is more likely to cooperate and remain still, resulting in better image quality and accurate diagnosis. Immobilization of the part, short exposure time, and physical restraint may also help in controlling motion, but they are not as effective or patient-friendly as a careful explanation of the procedure.Rate this question:

All of the following are methods used to help reduce colonic spasms during the radiographic examination of the barium-filled large bowel, EXCEPT
- A.
Lowering the enema bag a few inches
- B.
Placing the patient in Trendelenburg.
- C.
Administering glucagon prior to the exam.
- D.
Slowing or stopping the flow of barium.
Correct Answer
B. Placing the patient in Trendelenburg.Explanation
Placing the patient in Trendelenburg position involves tilting the patient's body with the head lower than the feet. This position is commonly used in medical procedures to increase blood flow to the head and upper body. However, it does not directly help reduce colonic spasms during a radiographic examination of the barium-filled large bowel. The other methods mentioned in the question, such as lowering the enema bag, administering glucagon, and slowing or stopping the flow of barium, are all techniques that can help reduce colonic spasms and improve the quality of the examination.Rate this question:

Which of the following is the correct examination scheduling sequence?
- A.
Upper GI series, Barium enema & intravenous pyelogram.
- B.
Barium enema, Upper GI & IVP
- C.
IVP, Barium enema & Upper GI.
- D.
IVP, Upper GI & Barium enema.
Correct Answer
C. IVP, Barium enema & Upper GI.Explanation
The correct examination scheduling sequence is IVP, Barium enema & Upper GI. This sequence is the correct order in which these examinations should be scheduled. The IVP (intravenous pyelogram) is typically performed first, followed by the Barium enema and then the Upper GI series. This sequence ensures that the examinations are performed in a logical and efficient manner, allowing for proper visualization and evaluation of the gastrointestinal and urinary systems.Rate this question:

All of the following are characteristics of the hypersthenic body type, EXCEPT
- A.
Short thoracic cavity
- B.
Short, wide, transverse heart
- C.
Diaphragm positioned low
- D.
Large bowel high and peripheral
Correct Answer
A. Short thoracic cavityExplanation
The hypersthenic body type is characterized by a short, wide, transverse heart, a diaphragm positioned low, and a large bowel that is high and peripheral. However, it does not have a short thoracic cavity. The thoracic cavity refers to the space within the chest that contains the heart, lungs, and other organs. In a hypersthenic body type, the thoracic cavity is not short, but rather it is deep and wide.Rate this question:

What event signals the completion of the small bowel series?
- A.
Barium enters the cecum of the large bowel via the ileocecal valve.
- B.
Barium in the appendix.
- C.
Barium in the ileum.
- D.
Barium in the rectum.
Correct Answer
A. Barium enters the cecum of the large bowel via the ileocecal valve.Explanation
The completion of the small bowel series is signaled by barium entering the cecum of the large bowel via the ileocecal valve. This indicates that the barium has successfully passed through the entire small intestine and has reached the beginning of the large intestine. Barium in the appendix, ileum, or rectum does not necessarily indicate the completion of the small bowel series, as it could be present in these areas for various reasons unrelated to the series.Rate this question:

Why must fluid be at the enema tip prior to inserting it in the rectum?
- A.
Venous emboli are avoided.
- B.
The instillation of air into the colon is avoided.
- C.
Air left in the tubing will slow the flow of fluid.
- D.
Air emboli are avoided.
Correct Answer
B. The instillation of air into the colon is avoided.Explanation
Prior to inserting the enema tip into the rectum, it is important to ensure that there is no air present in the tubing. This is because the instillation of air into the colon can cause discomfort and distension. It can also lead to the formation of air pockets, which may interfere with the proper administration of the enema. Therefore, by ensuring that there is no air in the tubing, the risk of instilling air into the colon is avoided.Rate this question:

Which statement is NOT true regarding large-bowel radiography?
- A.
The large bowel must be completely empty prior to examination.
- B.
Retained fecal material can stimulate pathology.
- C.
Single-contrast studies help to demonstrate polyps.
- D.
Double-contrast studies help to demonstrate intraluminal lesions.
Correct Answer
C. Single-contrast studies help to demonstrate polyps.Explanation
Single-contrast studies do not help to demonstrate polyps. In single-contrast studies, only one type of contrast agent is used, either barium sulfate or air, which allows for visualization of the overall shape and size of the large bowel. However, it does not provide detailed visualization of small lesions such as polyps. Double-contrast studies, on the other hand, involve the use of both barium sulfate and air, which allows for better visualization of smaller lesions like polyps.Rate this question:

Fluoroscopic imaging of the ileocecal valve is generally part of an
- A.
Esophagram
- B.
Upper GI Series
- C.
Small Bowel Series
- D.
Barium Enema
Correct Answer
C. Small Bowel SeriesExplanation
Fluoroscopic imaging of the ileocecal valve is generally part of a small bowel series. This is because the ileocecal valve is located between the small intestine and the large intestine, and a small bowel series is a radiographic examination that focuses on the small intestine. The small bowel series involves the ingestion of barium contrast material, which helps to visualize the structure and function of the small intestine, including the ileocecal valve. Therefore, it is the most appropriate option among the given choices.Rate this question:

Which is the correct sequence of events when performing double-contrast studies in Upper GI Series?
- A.
The patient is given a gas-producing substance, then given a small amount of high-density barium, then placed recumbent.
- B.
The patient is placed recumbent, given a small amount of high-density barium, then given a gas-producing substance.
- C.
The patient is given a gas-producing substance, placed recumbent, then given a small amount of high-density barium.
- D.
The patient is given a small amount of high-density barium, placed recumbent, then given a gas-producing substance.
Correct Answer
A. The patient is given a gas-producing substance, then given a small amount of high-density barium, then placed recumbent.Explanation
The correct sequence of events when performing double-contrast studies in Upper GI Series is to first give the patient a gas-producing substance, then give them a small amount of high-density barium, and finally place them in a recumbent position. This sequence allows for the gas-producing substance to create air bubbles in the stomach, which helps to distend the stomach and improve visualization. The high-density barium is then administered to coat the lining of the stomach and create contrast with the surrounding tissues. Placing the patient in a recumbent position ensures that the barium is evenly distributed and allows for better imaging of the upper gastrointestinal tract.Rate this question:

During a double-contrast BE, which position would afford the best double-contrast visualization of both colic flexures?
- A.
LAO and RPO
- B.
Lateral
- C.
Left Lateral Decubitus
- D.
AP or PA Erect
Correct Answer
D. AP or PA ErectExplanation
The AP or PA Erect position would afford the best double-contrast visualization of both colic flexures. This position allows for optimal separation and contrast between the colic flexures, providing clear visualization of any abnormalities or pathologies. The LAO and RPO positions may also provide some double-contrast visualization, but they may not be as effective as the AP or PA Erect position. The lateral position and left lateral decubitus position would not provide the desired double-contrast visualization of both colic flexures.Rate this question:

Which is recommended to demonstrate small amounts of air within the peritoneal cavity?
- A.
Lateral decubitus affected side up
- B.
Lateral decubitus affected side down
- C.
AP Trendelenburg
- D.
AP supine
Correct Answer
A. Lateral decubitus affected side upExplanation
Demonstrating small amounts of air within the peritoneal cavity is best achieved by performing a lateral decubitus X-ray with the affected side up. This position allows the air to rise and collect in the dependent part of the peritoneal cavity, making it easier to visualize on the X-ray. The other positions listed, such as lateral decubitus affected side down, AP Trendelenburg, and AP supine, may not effectively demonstrate the presence of small amounts of air in the peritoneal cavity.Rate this question:

Which position is required in order to demonstrate small amounts of fluid in the pleural cavity?
- A.
Lateral decubitus affected side up
- B.
Lateral decubitus affected side down
- C.
AP Trendelenburg
- D.
AP supine
Correct Answer
B. Lateral decubitus affected side downExplanation
To demonstrate small amounts of fluid in the pleural cavity, the patient should be positioned in a lateral decubitus position with the affected side down. This position allows the fluid to settle at the dependent portion of the pleural cavity, making it easier to visualize on imaging studies such as X-rays or CT scans. In this position, the fluid will accumulate at the lowermost part of the pleural cavity, making it more visible and aiding in diagnosis.Rate this question:

- Lateral decubitus
- AP trendelenburg
- A.
1 only
- B.
1 and 2
- C.
1 and 3
- D.
1, 2 and 3
Correct Answer
B. 1 and 2Explanation
The dorsal decubitus and lateral decubitus projections of the abdomen may be used to demonstrate air or fluid levels. The dorsal decubitus position involves the patient lying on their back, while the lateral decubitus position involves the patient lying on their side. Both of these positions can help to visualize air or fluid levels within the abdomen. The AP trendelenburg projection, on the other hand, is not typically used to demonstrate air or fluid levels in the abdomen.Rate this question:

Which best demonstrates the size and shape of the liver and kidneys?
- A.
Lateral abdomen
- B.
AP abdomen
- C.
Dorsal decubitus abdomen
- D.
Ventral decubitus abdomen
Correct Answer
B. AP abdomenExplanation
The AP abdomen best demonstrates the size and shape of the liver and kidneys. The AP (anterior-posterior) view allows for a frontal view of the organs, providing a comprehensive assessment of their size and shape. This view helps to identify any abnormalities or changes in the liver and kidneys, such as enlargement or tumors. The other options, lateral abdomen, dorsal decubitus abdomen, and ventral decubitus abdomen, may provide limited or different perspectives of the organs, making the AP abdomen the most suitable choice for evaluating their size and shape.Rate this question:

To demonstrate the large bowel, which view separates the overlying loops of the sigmoid colon?
- A.
Right lateral decubitus
- B.
Supine, with the tube angled 45 degrees caudally
- C.
Oblique, with the tube angled 45 degrees caudally
- D.
Prone
Correct Answer
B. Supine, with the tube angled 45 degrees caudallyExplanation
The correct answer is "Supine, with the tube angled 45 degrees caudally". In this position, the sigmoid colon is visualized separately from the overlying loops. The supine position allows for better visualization of the large bowel, and angling the tube 45 degrees caudally helps to separate the sigmoid colon from other loops. This view is commonly used in radiographic imaging to demonstrate the large bowel and identify any abnormalities or pathology.Rate this question:

In which of the following parts of the colon do most malignant tumors arise?
- A.
Hepatic flexure
- B.
Transverse
- C.
Recto-sigmoid
- D.
Cecum
Correct Answer
C. Recto-sigmoidExplanation
Most malignant tumors arise in the recto-sigmoid part of the colon. This area is the junction between the rectum and sigmoid colon, which is the last part of the large intestine before the rectum. The recto-sigmoid has a higher risk of developing tumors compared to other parts of the colon due to factors such as increased exposure to fecal material and longer transit time of stool, which can lead to the accumulation of genetic mutations and the development of malignant cells.Rate this question:
