Fluoroscopy AAPA Exam Questions With Complete
Solutions
0.25mm Correct Answers All people present during
fluoroscopic exposure must wear protective aprons of at least
what lead equivalent?
1-2 weeks Correct Answers Older, damaged cells of the corneal
epithelium are shed from the eye during blinking or tearing. The
cells is this layer are repopulated how often?
1. Duration
2. Distance
3. Protection Correct Answers What 3 principles are used to
manage radiation exposure to patients and healthcare personnel?
1. Fiber cells contain more cholesterol than any other than any
other cell in the human body.
2. Fiber cells produce crystallin, a protein that helps determine
how well the lens refracts light.
3. The loss of fiber cells contributes to the formation of
cataracts. Correct Answers What 3 things are true about the
fiber cells of the lens?
1. Improve image quality
2. Reduce magnification
3. Reduce patient dose Correct Answers During fluoroscopy,
the image intensifier should be as close to the patient as possible
for what reasons?
1. kVp
, 2. mA
3. Pulse Width Correct Answers Which factors does the
generator alter to maintain the appropriate entrance exposure at
the image receptor that minimizes patient entrance dose?
1. Last image hold
2. Gray-scale processing
3. Temporal frame averaging and edge enhancement Correct
Answers Image processing techniques available with digital
fluoroscopy include what?
1. Ordered by the physician in charge
2. Less restrictive methods have failed to protect the patient
Correct Answers In what circumstances should immobilization
devices be used?
1. Peak skin dose exceeds 3,000 mGy
2. Reference point air kerma exceeds 5,000 mGy
3. Kerma area product exceeds 500 Gy x cm2
4.Fluoroscopic procedure duration exceeds 1 hour Correct
Answers Patients should be monitored for radiation injury if
any one of the following sentinel events occurs?
1. They offer less image distortion
2. They have a wider dynamic range and better uniform contrast
resolution over the entire image
3. The equipment allows imaging staff to move patients easily
and provides more space for practitioners to maneuver
The cost is a drawback, however. They are much more
expensive than image intensifier systems Correct Answers
