Chest & Abdomen Proc. Flashcards
1
Q
- Chest AKA ______
- Chest Lies Between:
- Divided Into:
A
- Thorax
- Abdomen & Neck
- Bony Thorax, Respiratory System & Mediastinum
2
Q
- Bony Thorax Consist of:
- Upper Respiratory Consist of:
- Lower Respiratory Consist of:
A
- Sternum Anteriorly, Thoracic Vertabrae Posteriorly & 12 pairs of ribs ( 24 ribs total)
- Nose, Pharynx & Larynx
- Trachea, Bronchial Tree & Lungs
3
Q
- _____ = throat, passage for air and food
- _____ = Voicebox, first official part of resp. system
- Level ____ to ____
- ______ = Windpipe, Branches into R & L Bronchi
- Begins at level ____
- _____ - Where divides into R & L
- Level ______
A
- Pharynx
- Larynx
- C3-C6 - Trachea
- C6
- Carina
- T4-T5
4
Q
- Move air to and from alveoli: _____
- Which bronchus wider?
- Where are inhaled items usually lodged?
- _____ - exchange gases between lungs and blood
A
- Bronchi / Bronchioles
- RIGHT WIDER
- RIGHT
- Alveoli
5
Q
- Type of disease causes damage to alveoli sacs, causing SOB (usually from smoking)
- Organs of respiration:
- How many lobes on each side?
- Division of lungs:
A
- Emphysema
- Lungs
- R Lung = 3 lobes, L = 2 lobes
- Bronchi -> Bronchioles -> Alveoli
6
Q
- What is pleura?
- Layers of pluera:
- What is pnuemothorax?
- What is pleural effusion?
- What is hemothorax?
A
- Double layer membrane in each lung
- Parietal (outer)
- Visceral (inner)
- Pleural Cavity (space between) - Air/gas present in pleural cavity / collapse lung occurs
- Fluid in pleural cavity
- Blood in pleural cavity
7
Q
- Divisions of lungs:
A.
B.
C.
D.
E.
A
A. Apex - upper area above clavicles
B. Base - lower portion above diaphragm
C. Costophrenic Angle - extreme outermost corner each lung, ribs meet diaphragm
D. Hilum - Center area where bronchi, blood vessels lymph & nerves enter/leave lungs
E. Cardia Notch - Concavity inferior surface of left lung, shapes heart
8
Q
- Primary muscle inspiration:
- During inspiration:
- Expiration: - What is mediastinum?
- What does it contain?
- What is pericardium?
A
- Diaphragm
- Inspiration = INCREASE amount air volume in cavity, Muscle CONTRACTS
- Expiration = Muscle RELAXES, decrease air volume - Central portion of chest BETWEEN lungs
- Thymus Gland, Heart, Great Vessels, Trachea, Esophagus
( T.H.E.V.T) - Double layer sac encloses heart and roots
9
Q
CHEST X-RAY
1. SID / Why:
2. Why done Erect?
3.Respiration for Chest X-Rays:
4. When is inspiration & Expiration done for chest?
A
- 72
- Reduce heart magnification - Diaphragm moves down farther, air-fluid levels seen & prevent engorgement of pulmonary vessels
- SECOND FULL Inspiration
- Pnuemothorax
10
Q
- What Body Shape is imaged LEFT to RIGHT:
- Why is this important?
A
- Hyper
Sthenic
Hypo
Asthenic - Body habitus determines shape, position and movement of internal organs
11
Q
- What level is:
- Jugular Notch:
- Sternal Angle:
- Midway btwn Jugular Notch & Xiphoid Tip:
- Xiphoid Process: - How to find T7:
- Anteriorly
- Posteriorly
A
- JM = T2-T3
- SA = T4-T5
- T7
- XP = T9-T10 - Ant: 3-4 in inferior jug notch
- midway btwn jug notch & xiphoid
- Post 7-8in below C&
- inferior angle of scapula sits at T7
12
Q
PA Chest X-Ray:
CR
IR
Anatomy:
A
13
Q
Lateral Chest X-Ray:
CR
IR
Anatomy
A
14
Q
- Why is AP Supine Chest Xray done?
- AKA - How is IR positioned?
- CR for supine cxr:
- Anatomy seen:
A
- bedside portable / patient cant stand
- 1.5 in above shoulders
- CAUDAD to be perpendicular to long axis of sternum @ T7
- Anatomy (image)
15
Q
- What is required for air-fluid levels to be seen on cxr?
- Optimal projections:
- Why are oblique chests done?
- What is the obliquity for routine?
- Cardiac?
- CR & Respiration for PA oblique cxr?
- IR position
A
- Horizontal CR & Erect position
- PA Erect or Decubitus - Pathology of lungs, Determine size/contour of heart
- 45*
- 55-60* - See Image
