HESI RADIOGRAPHY EXAM 2025 UPDATED
ACTUAL EXAM WITH CORRECT SOLUTIONS.
Who discovered x-rays? - correct answer- Wilhelm Konrad
| | | | | | |
Roentgen
|
What are 9 characteristics of x-rays? - correct answer- 1. the
| | | | | | | | | |
ability to penetrate opaque substances
| | | | |
2. the ability to affect silver halide salts on films in the same
| | | | | | | | | | |
manner as light does
| | | |
3. the ability to stimulate or destroy tissue by ionization
| | | | | | | |
4. they travel at a constant speed, the speed of light
| | | | | | | | |
5. they cause fluorescence | |
6. they are high energy waves | | | |
7. they travel as electromagnetic waves or energy
| | | | | |
8. they have no mass | | |
9. they travel in a straight line and are invisible
| | | | | | | |
What is ionization? - correct answer- The production of ions by the
| | | | | | | | | | |
removal of electrons from the atoms of the matter that is struck by
| | | | | | | | | | | | |
the x-rays
| |

| | | | | |
When does ionization occur? - correct answer- whenever x- rays
| | | | | | | | |
penetrate matter
| |
What is an electric current? - correct answer- the flow of electrons
| | | | | | | | | | |
from one point to another or through a conductor
| | | | | | | | |
What is an electric current measured in? - correct answer-
| | | | | | | | |
amperes
|
What is a direct current? - correct answer- current flowing in one
| | | | | | | | | | |
direction, that is, from positive and negative. Direct current can be
| | | | | | | | | | |
interrupted at certain set intervals
| | | | |
What is kilovoltage usually designated as? - correct answer-
| | | | | | | |
Kilovoltage peak (kVp)
| | |
What is kilovoltage? - correct answer- the measure of the force
| | | | | | | | | |
between the negative cathode and the positive anode and
| | | | | | | | |
controls the energy of the electrons striking the tungsten target.
