10 ribs
Which of the following objects should be removed before chest radiography?

B. Bra E. Pants
C. Religious medallion around neck F. Hair fasteners
A, B, C, F, G
T/F Chest radiography is the most commonly repeated radiographic procedure because of poor positioning or exposure factor selection errors.
True
Chest radiography for the adult patient usually employs a kilovoltage peak of ____ to ____ kV.
110-125
T/F Generally, you do not need to use radiographic grids for adult patients for PA or lateral chest radiographs.
False
Optimal technical factor selection ensures proper penetration of the?
Heart, Great vessels, Lung region, Hilar region
Which of the following devices should be used for the erect PA and lateral chest projection for an infant
Pigg-o-stat
Describe the way optimum density of the lungs and mediastinal structures can be determined on a PA chest radiograph
should be able to see faint outlines of at least middle and upper vertebrae and ribs through the heart and other mediastinal.
T/F Because the heart is always located in the left thorax, the use of anatomic side markers on a PA chest projection may not be necessary.
False
Which one if the following sets of exposure factors is recommended for a chest examination of a young pediatric patient
70 to 85 kV, short exposure time
T/F Because they have shallower lung fields, the central ray is often centered higher for geriatric patients.
True
To ensure better lung inspiration during chest radiography, exposure should be made during the ____ inspiration
second
List 4 possible pathologic conditions that suggest the need for both inspiration and expiration PA chest radiographs.
Small pneumothorax, presence of foreign body, Fixation or lack of normal diaphragm movement, and distinguishing between opacity in rib or lung
List and explain briefly the three reasons chest radiographs should be taken with the patient in the erect position.
allows diaphragm to move down farther, show possible air and fluid levels in the chest, prevent engorgement and hyperemia of the pulmonary vessels.
Why do the lungs tend to expand more with the patient in an erect position than in a supine position?
Erect position causes abdominal organs to drop allowing the diaphragm to move farther down and the lungs to more fully aerate
Explain the primary purpose and benefit of performing chest radiography using 72 inch source image receptor distance.
Reduces distortion and magnification of the heart and other chest structures
what is a common radiographs sign seen on a chest radiograph for a patient with respiratory distress syndrome?
Air bronchogram
which one of the following anatomic structures is examined to determine rotation on a PA chest radiograph?
Symmetric appearance of sternoclavicular joints
Which positioning tip will help you prevent the patient's chin and neck from being superimposed over the upper airway and apices of the lungs for a PA chest radiograph?
extend the neck upward
For patients with the following clinical histories, which lateral projection would you perform-right or left?
Patient with serve pains in left side of chest
left
For patients with the following clinical histories, which lateral projection would you perform-right or left?
Patient with no chest pain but recent history of pneumonia in right lung
right
For patients with the following clinical histories, which lateral projection would you perform-right or left?
Patient with no chest pain or history of heart trouble
left
Why is it important to raise the patients arms above the head for lateral chest projections?
Prevents upper arm soft tissues from being superimposed over upper chest fields
The traditional central ray centering technique for the chest is to place the top of the image receptor _____ inches (____cm ) above the shoulders.
1 and a half to 2 inches, 5 cm
A recommended central ray centering technique for a PA chest projection require the technologist to palpate the _________ and measure down from that bony landmark _____ inches ( ____cm) for a male and ____ inches (____cm) for a female patient.
Vertebra prominens, 8 inches or 20 cm, 7 inches and 18 cm
Should the 14 x 17 inch image receptor be aligned lengthwise or crosswise for a PA chest projection of a hypersthenic patient?
crosswise
Should the 14 x 17 inch image receptor be aligned lengthwise or crosswise for a PA chest projection of a hyposthenic patient?
lengthwise
Which one of the following bony landmarks is palpated for centering of the AP chest projection?
Jugular notch
T/F With most digital chest units, the question of IR placement into either vertical or crosswise position is eliminated because of the larger IR
True
T/F For most patients, the central ray level for a PA chest projection is near the inferior angle of the scapula
True
T/F In general, for an average patient more collimation should be visible on the lower margin of the chest image than on the top for a PA or lateral chest position.
False. should be =
The height, or vertical dimension, of the average-to-larger person's chest is greater that the width or horizontal dimension.
False. greater width
T/F Single-photon emission computed tomography is frequently used to diagnose myocardial infraction.
