Semester 1 Exam 1 Chest & Abdomen Flashcards
A patient has a left-sided pleural effusion as demonstrated on a PA chest. The radiologist wants an additional view to demonstrate fluid levels. What position would best demonstrate this condition?
Left Lateral Decubitus
In the left lateral decubitus projection of the abdomen, free air will form shadows under the:
Right Hemidiaphragm
A properly exposed abdominal radiograph will exhibit the:
- psoas muscles
- lower border of the liver
- transverse processes of the lumbar vertebrae
1, 2, & 3
The plane that passes vertically through the body, dividing it into anterior and posterior halves, is termed the:
MCP Mid Coronal Plane
The average body type that comprises approximately half of the population is called:
Sthenic
What structure is best demonstrated on the lateral abdomen.
Abdominal Aorta
The shoulders are rolled forward for PA chest projections to:
Remove Scapula from lung field
For an upright PA chest examination, the top of the image receptor is placed:
1.5 inches above the shoulder
With the patient recumbent and the central ray directed horizontally, the patient is said to be in the
Decubitus position
Rupture of which of the following would be the most likely cause of free air on an upright abdomen image?
Colon
Pleural effusion is defined as:
Collection of fluid in pleural cavity
The ridge that marks the bifurcation of the trachea into right and left primary bronchi is the:
Carina
The imaginary plane that divides the body into equal right and left halves is called the:
Midsagittal
What position does NOT demonstrate free air levels within the abdomen?
Supine
Which term means lying down in any position?
Recumbent
Ileus is a condition caused by
Failure of bowel peristalis
Chest radiographs may demonstrate a condition known as pneumothorax. Pneumothorax is best defined as :
Air in the pleural cavity
What anatomical structures must be included abdominal radiography?
Diaphragm, pubic symphysis, psoas muscles
Which of the following is (are) recommended when positioning the patient for a lateral projection of the chest?
- The patient should be examined upright
- The shoulders should be depressed
- The shoulders should be rolled forward
1 only
What anatomical structures must be included on a PA projection of the chest?
distal cervical spine, outer border of the ribs, aortic knob
Which of the following terms implies that the central ray will be angled?
Axial
An effective way to determine if the PA chest radiograph is rotated is:
the asymmetric appearance of the sternoclavicular joints
What are the technical factors used for general Radiography?
SID, Kvp, mAs
Prior to bringing the patient into the radiographic room the radiographer should:
- assemble accessories needed for the exam
- be certain x-ray room is clean and orderly
- set appropriate technical factors
1,2,3
CR location for lateral chest should be
T6-T7
Why are chest x-rays ideally performed in the upright position at 72” SID?
- To demonstrate possible air/fluid levels.
- To move the diaphragm to its lowest possible position.
- To minimize distortion/magnification of the heart and great vessels.
1,2,3
For the left lateral decubitus abdomen position, the central ray should enter:
Patient positioned left side down with the central ray 2 inches above the crest
Which of the following terms describes where the central ray enters and exits the patient:
Projection
Which statements is true; regarding the correct method for imaging the abdomen in the supine position?
The central is directed perpendicular to the iliac crest.
A patient is standing with her right side against the image receptor. The position of the patient:
Right Lateral
The body habitus characterized by a massive build, short broad lung, and high and transverse organs is known as:
Hyperstenic
For the KUB radiograph, when should respiration be suspended, and what effect will that have on the diaphragm?
On full expiration the diaphragm is elevated
The body habitus characterized by a long and narrow thoracic cavity and low, midline stomach and gall bladder is the:
Asthenic
CR location for upright AP Abdomen
2 inches above the illiac crest
The upper most portion of the iliac crest is approximately at the same level as the:
4th lumbar vertebrae
Kvp range for PA chest with grid?
105-120
Which of the following structures must be demonstrated on the upright abdomen?
entire diaphragm
If a patient is too ill to stand for an upright abdomen, which of the following should be substituted?
Left lateral decubitus
The trachea is ___________to the esophagus:
Anterior
When viewing a supine abdomen radiograph, what criteria is used to determine that all necessary anatomy is included?
From pubic symphysis to diaphragm
What structures located within the abdomen allow for lifting ones legs and bending at the waist from front to back?
Psoas Muscles
A patient who is facing forward with his arms at his sides and palms facing forward is in the _____ position:
Anatomic
What is the best criterion to use to determine whether rotation exists on a lateral chest radiographic image?
Posterior ribs & lungs mostly superimposed
During deep inspiration the diaphragm is
lowered
Kvp range for abdominal radiography?
80-90
The abdomen is divided into four quadrants. How many regions is the abdomen divided into:
9
When reviewing a PA chest radiograph, how do you determine that the patient has taken a deep inspiration?
10 posterior ribs visualized
In cases of suspected bowel obstructions, a lateral decubitus projection of the abdomen would be taken to demonstrate:
Presence of gas or fluid levels
