Structure that serves as a passageway for both food and air pharynx
Structure that is most inferior? -Epiglottis -Hyoid Bone -Carina -Vocal Cords Carina
Structure that is most posterior -Larynx -Esophagus -Trachea -Hyoid Bone Esophagus
Air or gas that escapes into the pleural cavity results in a condition known as pneumothorax
Not part of the mediastinum Bronchi
Asthenic body type makes up approximately __ of the population 10%
Central Ray for AP supine Chest Centered to level of T7 Centered 8 to 10 cm below the jugular notch Angled approximately 5 degrees caudad
Which type of body habitus requires that the image receptor be placed crosswise rather than lengthwise for PA chest? Hypersthenic
General rule states that radiographic grids should be used in chest radiography for kilovoltage above 100 kV
Which of the following statement is not true The left bronchus is larger in diameter than the right bronchus
A well-inspired average adult chest PA projection will have a minimum of __ posterior ribs seen above the diaphragm 10
This object does NOT have to be removed or moved prior to chest radiography? Glasses
A correctly positioned lateral chest radiograph demonstrates some separation of the posterior ribs due to the divergent x-ray beam. A separation of more than __ indicates objectionable rotation from a true lateral/ 1 CM
Which of the following factors must be applied to minimize magnification of the heart 72 Inch SID
When using AEC for a PA chest projection which ionization chambers should be activated? Right and Left
During an AP chest radiograph, what receives the highest radiation dose? The Breast
For an average size female patient, where is the CR placed for a PA projection of the chest? 7 inches (17.8 cm) below vertebra prominens
When using AECwhich ionization chambers are activated for a left lateral projectoin of the Chest Center Chamber only
How much CR angle is required for the AP semiaxial projection for the lung apices? 15-20 Degrees
A Small pneumothorax may be detected by performing inspiration and expiration PA projections. TRUE
When using AEC, which ionization chambers should be activated on anterior obliques? Upper outside chambers
Why must a technologist slightly angle the CR caudad for most AP projections of the chest? This prevents clavicles from obscuring apices of lungs
When using AEC, which ionization chambers is/are normally activated for the PA projection of the chest? Two upper outside chambers
Which positioning line must be placed perpendicular to the plane of the IR for an AP projection of the upper airway? Acanthiomeatal

Pulmonary emboli no change in exposure factors
Pneumothorax patchy infiltrate with increased radiodensity
Emphysema increased lung dimensions
Pulmonary Edema Increased diffuse radiodensity in hilar regions and air-fluid levels
Malignant Lung Cancer slight shadows in early stages, larger radiopaque masses in advanced stages
COPD severe cases appear as emphysema
