The bony thorax consists of (5) | Sternum, clavicles, scapulae, ribs and thoracic vertebrae |
The two important bony landmarks of the thorax are | Jugular notch (AP) and vertebra prominens (PA) |
The four divisions of the respiratory system are | Pharynx, Trachea, Right and Left bronchi, Lungs |
The trachea is located anteriorly or posteriorly to the esophagus? | Anteriorly |
Air or gas that enters the space of the pleural cavity is a condition called | Pneumothorax |
Lower, concave portion of the lungs | Base |
Central area in which the bronchi and blood vessels enter the lungs | Hilum |
Upper, rounded portion above the level of the clavicles | Apices |
Extreme, outermost lower corner of the lungs | Costophrenic angles |
List the four important structures located in the mediastinum | Thymus, trachea, heart and great vessels, esophagus |
Which body type is associated with a broad and deep thorax? | Hypersthenic |
Which type of body habitus may cause the costophrenic angles to be cuttoff if careful vertical collimation is not used? | Hyposthenic and astehnic |
Chest radiography for the adult patient usually employs a kilovoltage peak of _________ to ________ kV | 110 to 125 |
What set of exposure factors is recommended for a chest exam of a young pediatric patient? | 70-85 kV, short exposure time |
To ensure better lung inspiration during chest radiography, exposure should be made during the ___________ inspiration | Second |
What anatomic structures is examined to determine rotation on a PA chest radiograph? | Symmetric appearance of sternoclavicular joints |
What is the name of the condition characterized by fluid entering the pleural cavity? | Pleural effusion |
Which specific position would be used if the patient were unable to stand but the physician suspected the pt had fluid in the left lung? | Left lateral decubitus |

Which specific position would be used if the patient were unable to stand but the physician suspected the pt had free air in the left pleural cavity? | Right lateral decubitus |
Which anterior oblique projection would best demonstrate the left lung (RAO or LAO)? | RAO |
Which posterior oblique projection would best demonstrate the left lung (RPO or LPO)? | LPO |
Condition in which collapse of all or portion of a lung | Atelectasis |
Irreversible dilation or widening of bronchi or bronchioles that may result from repeated pulmonary infection or obstruction | Bronchiectasis |
Condition in which excessive mucus is excreted into the bronchi | Bronchitis |
Form of persistent obstruction of the airways that usually causes difficulty in emptying the lungs of air. | COPD |
Most common of inherited diseases. Secretions of heavy mucus cause progressive "clogging" of bronchi and bronchioles | Cystic Fibrosis |
An irreversible and chronic lung disease in which air spaces in the alveoli become greatly enlarged as a result of alveolar wall destruction and loss of alveolar elasticity | Emphysema |
Abnormal accumulation of fluid in the pleural cavity | Pleural effusion |
