Correct Solutions
Anatomical differences between the left and right lungs
the right lung has three lobes while the left lung only has two due to the heart
Normal assessment findings for the lungs, regarding percussion, auscultation,
fremitus, and expansion
Percussion: Resonant sounds over both lungs, indicating air-filled spaces.
Auscultation: Clear breath sounds, including vesicular breath sounds (soft, low-pitched)
over most lung fields and bronchial sounds over the trachea.
Fremitus: Equal tactile fremitus bilaterally, with vibrations felt symmetrically when the
patient speaks.
Expansion: Symmetrical chest expansion with no restriction on deep inhalation, typically
2–5 cm.
When inspecting the anterior chest of an adult, you should note the (?) and (?) of the
chest wall.
shape and configuration
If the bronchial tree were obstructed, what affect would it have on auscultated lung
sounds?
Diminished breath sounds along with the presence of adventitious sounds like wheezes,
rhonchi, or crackles, depending on the severity and location of the obstruction,
indicating turbulent airflow through the narrowed airways.
Expected normal lung sounds throughout different lung regions
, Bronchial breath sounds are heard over the trachea and major bronchi, and are louder,
higher-pitched, with expiration longer than inspiration.
Bronchovesicular breath sounds are heard between the scapulae and around the
sternum; they are of intermediate intensity and pitch, with inspiration and expiration
equal in duration.
Vesicular breath sounds are heard over the peripheral lung fields and are soft and low-
pitched, with inspiration longer than expiration.
Normal costal angle is in degrees
90°
Where you would normally best palpate tactile fremitus
Near the clavicles and in between the shoulder blades
Characteristics and expected auscultation sites for bronchovesicular sounds.
Bronchovesicular breath sounds are heard between the scapulae and around the
sternum; they are of intermediate intensity and pitch, with inspiration and expiration
equal in duration.
A is the correct method to use when progressing from one auscultatory site on the
thorax to another
side-to-side comparison
can be an ominous sign of immediate patient danger (tension pneumothorax) and
should be attended to right away.
Tracheal deviation
Flow of blood from the right atrium through to the left ventricle.
