Lecture 4.1 physical exam section Flashcards
What are the 6 steps of an initial respiratory survey?
1) Listen for audible breathing
2) Assess rate > 25 signals distress
3) Inspect for retractions
4) Inspect the neck for accessory muscle use
5) Observe chest expansion
6) Check AP diameter
1) When you’re listening for audible breathing, what is ominous? What can cause this?
2) What should you check if they’re in distress?
1) Inspiratory stridor is ominous for upper airway obstruction: FB, or edematous tissue occluding airway
2) If they are in distress, check for color change (cyanosis and pallor)
1) What can cyanosis indicate?
2) When can pallor occur?
3) When does nail clubbing occur? Give examples
1) Cyanosis indicates hypoxia
2) Pallor can occur in heart failure
3) Clubbing of the nails occurs in chronic hypoxia:
COPD, Cancer, Bronchiectasis, congenital heart disease, CF
1) What RR signals distress?
2) What else should be assessed while you’re assessing RR?
1) >25/ min
2) Assess regularity of breathing
What two things should you observe while you’re observing chest expansion?
1) Bony deformity
2) Unilat impairment of motion
What should you be looking for when checking AP diameter?
Pt should be wider than they are deep; if they are nearly equal, it is a sign of advancing COPD
1) What can cause tenderness with palpation of the chest?
2) What should be compressed?
3) What should be palpated for tenderness?
1) Inflamed pleura / muscle soreness
2) The chest anterior to posterior
3) Costal cartilage tenderness (costochondritis)
1) How do you examine chest expansion? What are you watching for?
2) What may unilateral expansion be a sign of?
1) Placing thumbs at lower costal boarder have pt inspire deeply, watch for symmetrical motion of both as the cavity expands or contracts
2) Chronic fibrosis of lung pleura, pleural effusion, hemidiaphragm paralysis
1) What does diaphragmatic excursion test?
2) How should this be done, and what should be measured?
1) Diaphragmatic excursion tests how fully the lung is expanding
2) Do this using percussion, measuring the shift of the diaphragm posteriorly
Describe how to measure diaphragmatic excursion.
1) Where should you percuss?
2) What does this identify?
3) What should you do next?
4) What should you note, and what should the measurement be?
1) Percuss from resonance to dullness post.
2) This identifies the boarder of the diaphragm and the bottom of the thoracic cavity when lungs are not inflated
3) Have patient take a deep breath and do the same
-Exhale fully and do the same
4) Note the difference
~3-5 cm
1) What are tactile fremitus?
2) What are they normally?
1) Palpable vibrations that are transmitted through the pulmonary tree to the chest wall
2) Normally symmetric
1) How do you check for tactile fremitus?
2) Where is it best felt?
1) Use ball, fingertips, or ulnar surface of hands to check for vibrations as the patient speaks (have pt say “99”)
2) Interscapular area; disappears beneath the diaphragm
1) When is fremitus decreased?
2) What does this point to?
3) Give examples
1) Decreased when there is impediment of wave transmission
2) Thus, decreased transmission points either to too much mass or a lack of “connection”
3) Effusion or neoplasm (too much mass), PTX (cuts off connection to surface)
1) Increased transmission of tactile fremitus is seen in what condition?
2) What else would be present w this condition?
1) PNA
2) Jiggly jangly bits of exudate, puss, and gunk
1) During percussion, what can dullness replace? When?
2) What conditions is this indicative of?
3) What is hyperresonance indicative of?
4) How can you remember what causes dullness and what causes hyperresonance?
1) Dullness replaces resonance when fluid or solid tissue replaces air containing space
2) Lobar PNA, pleural effusion, hemothorax, empyema
3) Hyperinflated lungs of COPD (emphysema type), PTX, air-filled bulla
4) Drums are loud because they’re hollow
What are the two intercostal spaces you should palpate? Describe each
1) Anterior
-Manubrium > sternal notch > 2nd rib > 2nd intercostal space
-3rd, 4th, 5th, 6th, etc.
2) Posterior
-12th rib > 11th space
-10th, 9th, 8th, etc.

3) What is a resonant sound like? What is its pitch and where do you hear it?
1) Soft/short duration, high pitch, thigh
2) Medium loudness, middle pitch, liver
3) Getting loud/ medium duration, low pitch, healthy lung
1) What is a hyperresonant sound like? What is its pitch and where do you hear it?
2) What is a tympanitic sound like? What is its pitch and where do you hear it?
1) Loud/ longer duration, lower pitch, PTX
2) Loud, high pitch, gastric air bubble or puffed out cheek
1) How many places should you auscultate on the chest?
2) What about the back?
1) 6
2) 7
1) How should a pt be breathing when you’re listening to their lung sounds?
2) What direction should you move in? why?
3) What should you listen for each time?
1) With their mouth open
2) Go horizontally, you are not only listening; you are also comparing one side to the other
3) Listen to one full breath each time
Auscultation:
1) What pace should you perform it at?
2) Where are sounds louder? What should you do if this is not the case?
3) What could this indicate?
1) Go at their pace – not “breathe every time I move my stethoscope”
2) Usually, sounds are louder in the posterior lungs – if not, pay attention
3) Respiratory muscle weakness, COPD, effusion, ptx
What are bronchovesicular or bronchial breath sounds caused by?
Embedded airways that are blocked by inflammation or secretions
What are the 3 techniques to assess bronchovesicular or bronchial breath sounds? Describe each
1) Egophony: say “ee”
-You will hear “aaah”
2) Bronchophony: say “ninety-nine”
-You will hear these loudly, instead of being muffled (due to the jangly bits like in tactile fremitus)
3) Whispered pectoriloquy: have the pt whisper “ninety-nine”
-If you can hear it distinctly, you have demonstrated transmitted voice sounds again
Presence of egophony, bronchophony, and whispered pectoriloquy, plus a fever, does what?
Triples the likelihood of pneumonia
Define vesicular
The largely normal breath sounds
1) Describe vesicular breath sounds
2) What do you hear more of? What are you not likely to pick up?
3) How do spoken words sound like? What does “ee” sound like?
4) What do whispered words sound like?
5) Is there tactile fremitus?
1) Pretty soft
2) You hear more inspiration than expiration
-Not likely to pick up transmitted voice sounds on this patient
3) Spoken words will sound muffled and distinct; “ee” will sounds like “ee”
4) Whispered words will remain indistinct
5) You probably won’t pick up much tactile fremitus on this patient
1) What are “Broncho-vesicular” sounds like?
2) Describe the ratio of inspiration to expiration sounds
3) Where are they heard more? What indicates pathology?
1) Getting louder
2) Inspiration and expiration almost equal
3) In the first and second costal interspaces; when you hear them elsewhere that indicates pathology
1) What can broncho-vesicular sounds indicate?
2) What is this?
1) Think of an air-filled lung; that has become a consolidated lung
2) Consolidation: Think of the way a skin wound looks i.e.,
i.e., pneumonia
What may patients with a consolidated lung display?
1) Transmitted voice sounds; “ee” > “ah”
2) Spoken words are distinct through your stethoscope
3) Whispered sounds louder and clearer
4) Increased fremitus
5) You may also discover dullness to percussion
1) Describe the volume of bronchial sounds
2) Are expiratory and inspiratory respiratory sounds the same or different?
3) Where is it heard?
1) Getting loud
2) Expiratory sounds last longer than inspiratory ones
3) Normally over manubrium and large, proximal airways
1) What should you think when you hear bronchial signs when you’re listening anywhere besides the manubrium or large proximal airways?
2) Would other supportive PE findings match as well?
1) Follow the same thinking as you would in displaced broncho-vesicular sounds; air > consolidation
2) Would be likely to match as well; transmitted voice sounds, fremitus, etc.
1) Describe the volume of tracheal breath sounds
2) Describe the inspiratory and expiratory phase
3) What is the pitch like?
4) Where are these sounds heard?

2) High-pitched, sometimes musical sounding noise, whistley
3) Heard in “tight” airways; seen in asthma, respiratory distress
What should you think if a pt’s breathing/ chest is silent?
