Question 1

Which of the following x-rays may require medication and/or change of diet as preparation? 1.KUB
2)BE
3)IVP
4)UGI
5)chest x-ray (CXR)

Accepted Answer

An IVP,a BE,and a UGI study would require medication and/or change of diet as preparation.

Question 2

The patient's diagnostic study was ordered to be a lateral view.This means that the:

Accepted Answer

A lateral view is taken with the patient standing or lying on his or her side.

Question 3

Which of the following procedures would be performed by Nuclear Medicine?

Accepted Answer

A thyroid uptake and scan is performed to study thyroid gland performance.It demonstrates the ability of the thyroid gland to "take up" radioactive iodine.

Question 4

Contrast media refers to:

Accepted Answer

Contrast media are substances (solids,liquids,or gases)used in diagnostic imaging procedures that permit the radiologist to distinguish between different body soft tissue structures;these substances may be injected,swallowed,inhaled,or introduced by rectum.

Question 5

The patient's physician believes that a female patient may have an obstruction of the fallopian tubes.To more precisely visualize these reproductive organs with the introduction of contrast medium,the physician is most likely to order a(n):

Accepted Answer

A hysterosalpingogram is an x-ray of the uterus and fallopian tubes that is made after injection of a contrast medium.

Question 6

Which of the following is TRUE of diagnostic imaging procedures?

Accepted Answer

It is the responsibility of the HUC to prepare the consent form for the patient's signature.This is true when either paper charts or electronic medical records (EMR)are used.

Question 7

A male patient has a significant amount of pain in his stomach and upper abdomen with no other symptoms.A study in which fluoroscopy,a viewing screen,and an x-ray machine are used and that the doctor is most likely to order is a:

Accepted Answer

A UGI x-ray with a small bowel follow-through (SBFT)uses fluoroscopy,a viewing screen,and an x-ray machine to examine the distal portion of the esophagus,stomach,and small intestines.

Question 8

The abbreviation KUB refers to kidneys,_____,and bladder.

Accepted Answer

KUB is an abdominal study that includes the region of the kidneys,ureters,and bladder.

Question 9

If the physician suspects a pulmonary embolism,which examination would be ordered?

Accepted Answer

A lung perfusion/ventilation study is performed to diagnose a pulmonary embolism.

Question 10

An example of a nuclear total body scan is a:

Accepted Answer

A gallium scan is a total body scan that also may be ordered regionally.

Question 11

A signed consent for a diagnostic procedure is required when:

Accepted Answer

Diagnostic imaging procedures that are invasive-those that require the injection of contrast medium-require the patient to sign a consent form after he or she has been informed of the procedure,risks,alternatives,outcomes,etc.

Question 12

Which of the following sequences (order of scheduling)of diagnostic studies would be appropriate?

Accepted Answer

X-ray studies of the lower spine and pelvis,abdominal studies based on US or computed tomography (CT),liver and bone scans,and nuclear medicine studies should be ordered before a BE or a UGI study is performed.The presence of barium in specific parts of the body may obscure the portion of the body that is being studied.

Question 13

The division of diagnostic imaging that uses radioactive materials called radiopharmaceuticals to assess the functioning capacity of organs is:

Accepted Answer

Nuclear medicine imaging uses radioactive materials called radiopharmaceuticals to evaluate the functioning capacity of organs.

Question 14

Which of the following is required to include when one is communicating a diagnostic imaging order?

Accepted Answer

The CI (the reason the doctor is ordering the procedure)must be recorded by the HUC when a diagnostic imaging procedure is ordered.Insurance companies require this information before they will provide reimbursement to health care facilities.Diagnostic imaging departments will not perform procedures until they have received the recorded CI.

Question 15

A patient who has a pacemaker or a cerebral aneurysm clip could not undergo which of the following procedures?

Accepted Answer

MRI is a technique for viewing the interior of the body with the use of powerful magnetic fields,radio waves,and a computer to produce images of body structures.Because of the strength of the magnet and the radiofrequency waves,contraindications exist for some patients,including those with pacemakers and metal clips.

Question 16

Certain organs and blood vessels within the body are difficult for the radiologist to see because there is little difference in density between them and their surrounding parts.To increase the contrast:

Accepted Answer

Differences in density are due to the degree of absorption offered by different tissues and air to the radiation.It is easy to differentiate bony structures because bones offer resistance and therefore appear light on the image.

Question 17

The procedure that uses high-frequency sound waves to create an image of body organs is:

Accepted Answer

US,also called sonography,uses high-frequency sound waves to create an image of body organs.

Question 18

The abbreviation AP in the x-ray department refers to:

Accepted Answer

Anteroposterior (AP)refers to a view taken while patients are standing or lying on their backs (supine);the machine is placed in front of the patient.

Question 19

The diagnostic imaging technique that provides a computerized image that reproduces a section of the abdomen and pelvis as if horizontally sliced from front to back is:

Accepted Answer

CT is a radiographic process in which ionizing radiation is used to create computerized images (scans)of body organs in sections.It can be coronal as well.

Question 20

An IVU exam is performed to outline the:

Accepted Answer

An IVU is a procedure that is performed to outline the kidney,particularly the renal pelvis,ureters,and urinary bladder.
