What is the name of the tongue-shaped process on the anterior-medial border of the left lung? lingula
Which plane must be accurately parallel with the IR to prevent distortion of the thoracic structures during a lateral chest radiograph? midsaggittal plane
The part of the lung that extends above the clavicle is termed the: apex
Where should the top of the IR be positioned for an AP oblique projection of the lungs? 1 1/2 - 2 inches above the vertebral prominens
Which side of the patient's chest is placed against the vertical IR for a ventral or dorsal decubitus lateral projection? Affected side
The costophrenic angle is a part of the: lungs
The area between the two lungs is termed the: mediastinum
Each lung is divided into specific segments called: lobes
Which of the following will be observed on a supine AP chest radiograph? 1) clavicles projected higher 2) lung fields appear shorter 3) all 12 ribs are seen 1 and 2
The right lung is about how much shorter than the left? 1 inch
Where are the hands placed for a PA projection of the chest? back of the hands on the hips
Which of the following would not be included in the mediastinum? (1) thymus (2) larynx (3) diaphragm 2 & 3
Which of the following exposure techniques is required to penetrate all of the thoracic anatomy? high kVp
The thoracic cavity is enclosed with a shiny, slippery lining called the: serous membrane
When fluid replaces air in the lung interstitium and alveoli, the patient is said to have: pulmonary edema
Fluid that collects in the pleural cavity is termed: pleural effusion
How far above the shoulders should the IR be positioned for PA and lateral chest radiographs? 1.5 to 2 inches
What is the name of the double-walled serous membrane sac that encloses the lung? pleura
The thoracic viscera consists of the: (1) lungs (2) mediastinum (3) diaphragm Lungs and mediastinum
The lungs are composed of a light, spongy, elastic substance called the: parenchyma
Which of the following are a part of the mediastinum? (1) lungs (2) heart (3) esophagus 2 & 3

Which positioning maneuver moves the scapulae out of the lateral aspects of the lungs? rolling the shoulders forward
The thoracic cavity contains which of the following: (1) heart (2) thymus gland (3) inferior esophagus 1,2,3
How many ribs should be visible above the diaphragm on a PA chest radiograph? 10
Which of the following best describes the position of the thymus gland? behind the manubrium
The space between the two pleural walls is called the: pleural cavity
If the lateral decubitus position is used to demonstrate free air in the pleural cavity, which side must the patient lie on? unaffected side
When the patient is properly positioned for a PA oblique of the chest, the central ray will enter the body: Midway between the lateral surface of the elevated side and the spine
