Mosby's 110 Review Realistic Practice
Exam: Test Yourself Before the Big Day!
What is the single largest source of natural background radiation? - ✔ ✔ radon
What is the unit of air kerma? - ✔ ✔ grayA
What supports and protects the x-ray tube, restricts leakage radiation during exposure, and provides
electrical insulation? - ✔ ✔ tube housing
What type of treatment will be required for a patient suffering from anoxia? - ✔ ✔ oxygen therapy
When a bone is being radiographed to evaluate a fracture, the tube, part, and IR must be in: - ✔ ✔
parallel planes
When an AEC is used, the backup timer: - ✔ ✔ the backup timer protects the patient from
overexposure and prevents the x-ray tube from overheating.
When handling hazardous materials, the following should be worn: - ✔ ✔ PPE
When human tissues lack sufficient oxygen, the skin demonstrates: - ✔ ✔ blue color
When initiating treatment for a patient who is in shock, after calling for help what should the
radiographer do?
1. Determine blood pressure
2. Administer oxygen
3. Place the patient in the Trendelenburg position
4. Initiate CPR - ✔ ✔ 1,2,3
When kilovoltage is increased:
1. intensity increases.
2. wavelengths become shorter.
3. wavelengths become longer. - ✔ ✔ 1,2
, A case in which the injured person caused some of the injury is called: - ✔ ✔ contributory negligance
A central ray angle of 25 to 30 degrees caudad is required for what projection? - ✔ ✔ PA axial
clavicle
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: - ✔ ✔
increase
A fracture caused by acute hyperextension of the head on the neck is: - ✔ ✔ hangmans fx
A fracture that runs at a right angle to the long axis of the bone is: - ✔ ✔ transverse fx
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. - ✔
✔ 1 and 3
An image with few gray tones, mainly black and white, is referred to as: - ✔ ✔ short scale contrast,
high contrast
an undistorted radiographic image will result when the object plane and the image plane are: - ✔ ✔
parallel
As the wavelength of the x-rays increases, penetrating ability: - ✔ ✔ decreases
At which of the following anatomic locations can a pulse be obtained?
1. At the angle of the mandible
2. Behind the knee
3. On the anterolateral border of the wrist - ✔ ✔ 1,2,3
Autotransformers operate on the principle of: - ✔ ✔ self induction
Before moving a patient, the radiographer should assess which of the following?
