Thorax Flashcards
1
Q
congestive heart failure (trachea, tactile fremitus, percussion, breath sounds, adventitious sounds)
A
- Trachea - midline
- Tactile Fremitus - decreased
- Percussion – resonant Breath sounds – vesicular
- Adventitious sounds – late inspiratory crackles in the dependent portions of lungs; possibly wheezes.
Notes: engorged capillaries where air exchange is occurring in the lungs
Makes dependent airways deflate.
2
Q
Pneumothorax (trachea, tactile fremitus, percussion, breath sounds, adventitious sounds)
A
Trachea – shifted toward opposite side if much air
Tactile Fremitus – decreased to absent over pleural air
Percussion –hyperresonant to tympanic over pleural air
Breath sounds – decreased to absent over pleural air
Adventitious sounds – none, except a possible pleural rub
3
Q
Pleural Effusion (trachea, tactile fremitus, percussion, breath sounds, adventitious sounds)
A
Trachea – shifted toward opposite side in large effusion
Tactile Fremitus – decreased to absent
Percussion – dull to flat over fluid
Breath sounds – decreased to absent, but bronchial sounds may be heard near top of large effusion
Adventitious sounds – none, except a possible rub
Note: blocks the transmission of sound and also collapses the alveoli
4
Q
Asthma (trachea, tactile fremitus, percussion, breath sounds, adventitious sounds)
A
Trachea - midline
Tactile Fremitus - decreased
Percussion – resonant to hyperresonant
Breath sounds – often obscured by wheezes
Adventitious sounds – wheezes, possibly crackles
Notes:
- constriction in the bronchi, also get edema
- Lungs will overinflate when you have an asthma attack
- Widespread narrowing of the trachobronchial tree as well as bronchospasms
5
Q
Emphysema (trachea, tactile fremitus, percussion, breath sounds, adventitious sounds)
A
Trachea - midline Tactile Fremitus - decreased Percussion – hyperresonant Breath sounds – decreased to absent Adventitious sounds –none or scattered coarse crackles in early inspiration and perhaps expiration; or wheezes and rhonchi associated with chronic bronchitis
Note:
- alveoli become distended and patient cannot get the air out
- Hyperresonant percussions – not quite tympanic, like you would hear over the stomach, but there is more air trapped in the lung
6
Q
Bronchitis (trachea, tactile fremitus, percussion, breath sounds, adventitious sounds)
A
Trachea - midline
Tactile Fremitus - normal
Percussion – resonant
Breath sounds – vesicular except perhaps over large bronchi or trachea
Adventitious sounds –none or scattered coarse crackles in early inspiration and perhaps expiration; or wheezes and rhonchi
Notes:
- inflammation in the bronchioles
- Copious secretions of mucus
- You can get some airway obstruction
- Productive cough
7

10
Q
developmental considerations for older adults

- Chest expansion may be somewhat decreased.
- Older person may fatigue easily. Allow brief rest periods with quiet breathing.
11
Q
developmental considerations for infants and children
A
- Let the parent hold supported against the chest or shoulder. Offer the stethoscope to children.
- Infants have a rounded thorax until age 6.
- Infants breath through the nose rather than mouth until age 3 months.
- The diaphragm is the major respiratory muscle.
- Infant Rate 30-40
- Auscultation normally is bronchovesicular breath sounds in the peripheral lung field up to age 6.

Costal angle should be
19
Q
facial expressions
A
- pink puffer: pink complexion, shortness of breath, sitting in tripod position
- blue bloater: cyanosis, right-sided heart failure, this is also caused by COPD, whether that’s chronic bronchitis or emphysema
20
Q
respiration patterns (normal vs. 5 abnormalities)
A
- Tachypnea
- Bradypnea
- Kussmaul
- Cheyne-Stokes
- Biot’s
21
Q
Biot’s
A
- Less regular than Cheyne-Stokes; periods of increased depth and flow followed by a period of apnea
- Occurs from brain trauma, heat stroke, abscess in the brain
22
Q
Cheyne-Stokes
A
- respirations wax and wane in an irregular pattern – shallow to deep, then period of 20 seconds with no breathing at all, and so on
- occurs with increase ICP, renal failure
23
Q
Kussmaul
A
- Tachypnea (rapid) but a much deeper breathing than regular tachypnea
- occurs with diabetics
24
Q
Bradypnea
A
- less than 10 respirations per minute
- can occur as a result of drugs (morphine), increased intracranial pressure
25
Tachypnea
- increased respirations (24, over 20)
| - occurs after exercise, with fever, pneumonia, emotion
26
Palpate for symmetric expansion
1. Place both hands on posterior chest with thumbs at T9 or T10.
2. Pinch up a small fold of skin.
3. Ask person to take a deep breath.
Your thumbs should move apart symmetrically
27
Palpate for tactile fremitus
- Use palmar base of finger or ulnar edge, touch chest while patient say ninety-nine
- Start over apices and palpate from side to side or compare sides
- Sound is conducted better through a dense or solid structure than porous so anything that increase density of lung will increase fremitus
28
abnormal tactile fremitus: increased vs. decreased
- Increased tactile fremitus: pneumonia, pus, etc.
- Decreased tactile fremitus: anything that obstructs transmission of sound from the larynx through the bronchi out to the chest wall, when lung is collapsed
29
3 kinds of Transmitted Voice Sounds

47
percussions of the posterior chest
i. Percussion is tapping with a very relaxed wrist, tapping middle finger
ii. Trying to listen to the underlying structures

pneumonia or pleural effusion
91
what is hyperresonance, and what kind of patient do you hear that in?
COPD, emphysema
Resonance increased above the normal, and often of lower pitch, on percussion of an area of the body; occurs in the chest as a result of overinflation of the lung as in emphysema or pneumothorax and in the abdomen over distended bowel
92

what is arterial insufficiency?
patients are not getting enough oxygenated blood to their extremities
usually the legs b/c they are most dependent
nails get thicker, hair, skin feels cool
94
What happens in congestive heart failure?
the capillaries that are coming from inside the heart are very dilated, which can leads to fluid overload, pulmonary edema
