    through the center of the sternum
  4. where is this landmark? midclavicular line.
    through the midpoint of the clavicle
  5. where is this landmark? anterior axillary line.
    through the anterior axillary folds
  6. where is this landmark? midaxiallary line.
    through the apex of the axillae
  7. where is this land mark? posterior axillary line.
    throught the posterior axillary fold
  8. where si this land mark? right/left scapular lines.
    through the inferior angle of the scapula
  9. where is this landmark? vetebral line.
    along the center of the spine
  10. where are percussion & ausculatory sites?
    • posterior thorax
    • anterior throax
    • should occur side to side
  11. how can you maxamize the sounds heard?
    • have client take deep breaths w/ open mouth each time stethescope is moved
    • placing the stethescope directly on clients skin
    • facillitating client breathing by medicating for pain, giving clear direction, and assisting the client to sitting position
  12. how is the posterior thorax best assessed?
    sitting or standing
  13. how is the anterior throax best assessed?
    • sitting
    • standing
    • lying
  14. what types of things should be noted while inspecting cleints respiratory effort?
    • rate and pattern- should be regular 16-20 min
    • character of breathing (diphragmatic, abdominal, thoracic)
    • use of accessory muscles
    • chest wall expansion
    • depth of respiration- unlabored, queit breathing
  15. how do you assess tactile fremitus?
    • palpate the chest wall using the ulnar suface of both hands comparng side to side
    • ask the client to say "99" each time hands are moved
    • expected finding- vibration is symmetrical and more pronounced over large airways
  16. what should the normal sound by percussion be over the throax?
  17. what would dullness indicate?
    fluid or solid tissue which may be indicative of pneumonia or a tumor
  18. what would hyperresonance indicate?
    caused by the presence of air which may be indicative of pneumothorax or emphysema
  19. defn. is it normal or abnormal?
    • loud
    • high pitched
    • expiration heard longer than inspiration over trachea
    • expected
  20. defn. expected or unexpected?
    • medium pitch and intensity, equal inspiration and expiration, heard over large airways
    • expected
  21. defn. expected or unexpected?
    • soft, low-pitched, inspiration heard long expiration heard over most of the lung
    • expected
  22. crackles/rales: explain what causes it
    fine to coarse popping heard as air passess through fluid or re-expands collapsed small airways
  23. wheezes: explain what causes it and what it sounds like
    high pitched whistling, musical sounds, heard as air passes through narrowed airways
  24. pleural friction rub: explain what it sounds like and what causes it
    grating sound produced as the inflammed visceral and parietal pleura rub against each other during insperation
