FLUOROSCOPY CERTIFICATION
EVALUATION SET COMPLETE
QUESTIONS AND ANSWERS
◉ Too much lighting during a fluoroscopy exam:
a) Helps to see images better
b) Improves visualization of television images
c) May increase fluoroscopy time
d) Helps with the luminescence of the image Answer: c) May
increase fluoroscopy time
Explanation:
It is important to adjust the lights in the room when performing
fluoroscopy. Excess lighting decreases the eyes ability to resolve
images and will lead to increased radiation exposure.
◉ Humans can detect ionizing radiation as it passes through their
body.
,a) TRUE
b) FALSE Answer: b) FALSE
Explanation:
Humans cannot detect ionizing radiation as it passes through their
body.
◉ What is the threshold dose?
a) The actual radiation dose a patient receives
b) The maximum radiation dose allowed
c) The radiation dose below which there is no effect
d) The radiation dose above which there is no effect. Answer: c) The
radiation dose below which there is no effect
Explanation:
,A threshold dose is one in which a minimum amount of radiation
(threshold) is required before it causes any deleterious effects.
◉ When are thyroid shields used by operators?
At the discretion of the operator
Thyroid shields always need to be used
During all fluoroscopic procedures
During all radiographic procedures
When the operator is close to the patient during fluoroscopy
Answer: When the operator is close to the patient during
fluoroscopy
Explanation:
Thyroid shields are generally used when the wearer is in close
proximity to the patient during fluoroscopy, however, are not
required for all fluoroscopic exams.
◉ The following are nonstochastic effects:
, select all that apply
a) Bone marrow cell depletion
b) Somatic effects
c) Non-malignant skin damage
d) Cataracts
e) Carcinogenesis Answer: a) Bone marrow cell depletion
c) Non-malignant skin damage
d) Cataracts
Explanation:
Nonstochastic effects are those for which the severity varies with
radiation dose. Examples of nonstochastic effects include cataracts,
non-malignant skin damage, and bone marrow depletion. Somatic
effects and carcinogenesis are examples of stochastic effects.
