QUESTIONS AND ANSWERS
What are possible results of ionization?
1. Unstable atoms
2. Production of low-energy x-rays
3. Formation of new molecules harmful to the cell - CORRECT ANSWER-1,2,3
OSL dosimeters may be worn as long as: - CORRECT ANSWER-1 quarter
The annual effective absorbed dose equivalent limit for the general public, assuming
infrequent exposure, is: - CORRECT ANSWER-5msv
The photon-tissue interaction that does not because ionization is: - CORRECT
ANSWER-coherent
Before moving a patient, the radiographer should assess which of the following?
1. The patient's ability to breathe
2. The presence of nausea
3. The presence of sensitive or thin skin
4. The patient's level of consciousness - CORRECT ANSWER-1,2,3,4
The wrist and ankle have what type of movement? - CORRECT ANSWER-gliding
This causes anatomic structures to appear longer on the image than in reality: -
CORRECT ANSWER-elongation
The type of shock that causes blood to pool in peripheral vessels is called: - CORRECT
ANSWER-neurogenic shock
This item is used to administer oxygen through the nose: - CORRECT ANSWER-nasal
cannula
The upper part of the sternum is called the: - CORRECT ANSWER-manubrium
What dose-response curve best illustrates cataract genesis, which does not occur at
low levels of radiation exposure? - CORRECT ANSWER-threshold
, A cross table lateral projection of the cervical spine of a trauma patient is to be taken
with a mobile radiographic unit. In addition to using a high-speed image receptor
system, the radiographer uses a stationary 8:1 grid. This results in the following change
in absorbed dose for the patient: - CORRECT ANSWER-increase
When human tissues lack sufficient oxygen, the skin demonstrates: - CORRECT
ANSWER-blue color
The voltage actually used in three-phase, 12-pulse units is about: - CORRECT
ANSWER-96% kip on control panel
The cardiac portion is where the: - CORRECT ANSWER-esophagus enters the
stomach
A fracture caused by acute hyperextension of the head on the neck is: - CORRECT
ANSWER-hangman’s fox
high kip= ___ contrast - CORRECT ANSWER-lower
An image produced by using a horizontal beam is useful in the evaluation of
1. fluid-filled sinuses.
2. free air in the abdomen taken with the left side of the patient superior and the right
side inferior.
3. free air in the abdomen taken with the right side of the patient superior and the left
side inferior. - CORRECT ANSWER-1 and 3
Thermoluminescent dosimeters measure doses as low as: - CORRECT ANSWER-50
gay
Which of the following correctly indicates the different forms of energy, in proper
progression, that make up the fluoroscopic image as produced by an image intensifier?
- CORRECT ANSWER-. X-ray photons, light photons, electrons, light photons
This type of timer is controlled by a microprocessor: - CORRECT ANSWER-electronic
This type of transformer contains an iron core and a single winding of wire, it is used in
the x-ray circuit to provide a small increase in voltage before the step-up transformer,
and it is here that the kept settings are made. This is the: - CORRECT ANSWER-
autotransformer
