Question 1

Which of the following procedures helps in directing radiation for tumor masses?&#10;A)PET scan&#10;B)CT scan &#160;&#10;C)Ultrasound&#10;D)MRI &#160;&#10;E)Fluoroscopy

Accepted Answer

CT scan helps in directing radiation for tumor masses as it provides detailed imaging of the tumor location, size, and shape. This helps the radiation oncologist in planning the radiation therapy by determining the precise target area and minimizing damage to surrounding healthy tissues. PET scan, MRI, and ultrasound are imaging techniques that may be used in cancer diagnosis and staging, but they do not provide as accurate information for directing radiation as CT scans. Fluoroscopy is a real-time imaging technique used to guide certain medical procedures, but it is not typically used for radiation therapy planning.

Which of the following is used to emit and receive sound waves when ultrasound is performed?&#10;A)Oscilloscope&#10;B)Transilluminator &#160;&#10;C)Transducer&#10;D)Radionuclide

Accepted Answer

A transducer is used to emit and receive sound waves during ultrasound. An oscilloscope is an electronic instrument used for visualizing electrical signals, a transilluminator is a device used to transmit light through tissues, and radionuclide is a radioactive compound used in medical imaging.

Accepted Answer

This statement is not entirely true. While the films themselves may be physically owned by the patient, the information contained within them (such as the images) are the property of the healthcare provider and must be treated as confidential medical information.

Question 5

Which of the following procedures produces a series of cross-sectional images?&#10;A)PET scan&#10;B)CT scan &#160;&#10;C)Ultrasound&#10;D)MRI &#160;&#10;E)Fluoroscopy

Question 6

Mrs.Lane is scheduled for a barium enema in 3 days.For which of the following diseases is this test primarily performed?&#10;A)Hiatal hernia&#10;B)Esophageal varices &#160;&#10;C)Polyps, tumors, and lesions&#10;D)Kidney blockage

Accepted Answer

Barium enema is primarily performed to detect polyps, tumors, and lesions in the colon and rectum. It involves the use of barium, a contrast material that is swallowed or inserted into the rectum to help produce clear X-ray images of the lower digestive tract. Hiatal hernia, esophageal varices, and kidney blockage are not typically diagnosed with a barium enema.

Question 7

Which of the following is part of patient preparation?&#10;A)Ensure thorough patient knowledge of the procedure.&#160;&#10;B)Ensure that patient understands the preparation.&#160;&#10;C)Verbal instructions are given.&#160;&#10;D)Written instructions are taken home.&#160;&#10;E)All the above.

Accepted Answer

All of the listed choices are important components of patient preparation. It is essential that patients thoroughly understand the procedure they are about to undergo and the steps they need to take in preparation for it. Verbal instructions should be given to ensure that patients have a clear understanding, and written instructions should also be provided so that patients can refer to them at home if necessary.
