Bontrager Chapter 2 Self Test & Review Questions Chest
Chest Anatomy and Respiratory Structure

1. Key Terms:

- Sternum: Breastbone

- Thyroid Cartilage: Adam's apple

- Scapula: Shoulder blade

- Clavicle: Collar bone

- Vertebra Prominens: The correct term for the seventh cervical vertebra.

- Jugular Notch: A depression located on the superior portion of the sternum.



2. Bronchi and Associated Structures:

- Right and Left Bronchi: Formed by the bifurcation of the trachea.

- Carina: The ridge found at the point where the internal distal trachea divides into the bronchi.

- Hilum: Area of each lung where bronchi and blood vessels enter and leave.

- Alveoli: Small air sacs where gas exchange occurs.



3. Pleura and Related Conditions:

- Hilar Pleura: Not an aspect of the pleura.

- Aspects of the Pleura:

- Parietal Pleura

- Pleural Cavity

- Pulmonary (Visceral) Pleura

- Hemothorax: Condition where blood fills the potential space between pleura layers.



4. Lung Anatomy:

- Costophrenic Angle: Extreme, outermost lower corner of each lung.

- Mediastinum Structures: Thymus gland, heart, greater vessels, trachea, and esophagus.

, ### Thoracic Anatomy:

- Bony Thorax Components:

- Sternum, two clavicles, two scapulae, 12 pairs of ribs, and 12 thoracic vertebrae.



### Body Habitus:

1. Asthenic Body Habitus: Characterized by a narrow thorax that is shallow from front to back but long in
vertical dimension.



### Radiographic Considerations:

1. Best kV and SID for Adult Chest Radiography:

- 125 kV and 72-inch SID

2. Shoulder Positioning:

- Pressed downward and toward the IR to reduce chest rotation; rolled forward to remove scapulae
from lung fields.

3. Central Ray Placement for AP Supine Projection of Chest:

- 3 to 4 inches below the jugular notch.



### Respiratory Conditions:

1. Dyspnea: Defined as shortness of breath.

2. Atelectasis: Condition where all or portion of the lung is collapsed.

3. Pulmonary Edema: Condition where excess fluid builds in the lungs due to obstruction of pulmonary
circulation.



### Positioning Errors:

1. PA Chest Radiography Error:

- Rotation into a LAO position results in superimposition of the left sternoclavicular joint over the
spine.

2. Lateral Chest Radiograph Projection Error:

- Raise upper limbs higher to prevent soft tissue from obscuring the apices of the lungs.
