Lower Respiratory Tract Exam Flashcards

1
Q

What does a pulse oximeter do; what does each light measure?

A

Direct beams of red and infrared light through a measurement site.

Red light: oxyhemoglobin

Blue light: deoxyhemoglobin

% saturation = red / red + blue

Q

What is an incentive spirometer used for?

A

Device used to help you keep your lungs healthy after surgery or when you have a lung illness. Teaches you how to take slow deep breaths. Important to breath in SLOWLY

Q

Discuss tactile fremitus technique and what abnormal findings mean (decreased and increased when)?

A
  • Palpable vibrations transmitted through the bronchopulmonary tree to the chest wall as person speaks

Q

What is done in a diaphragmatic excursion; normal measurement, what does higher than normal dullness indicate?

A
  • You determine the distance between the levels of dullness during expiration and inspiration.
  • Normal is 3-5.5
  • If dullness is higher than normal, suspect atelectasis or phrenic nerve paralysis

Q

What are the 4 normal breath sounds and what do you hear/where are they best heard?

A

1) Vesicular - soft, low pitched, heard over most of lungs
2) Bronchovesicular - slightly higher pitch and heard best at 1st/2nd intercostal space
3) bronchial - loud and high pitched, heard over the bronchi/manubrium
4) Tracheal - Super loud and high pitched. Best over trachea… duh

21
Q

What do pursed lips indicate for a patients lung exam?

A

Obstructive lung disease

22
Q

Where is the sternal angle?

A

Also known as the angle of Louis. This is where the second rib meets the manubrium

23
Q

What is the landmark for needle decompression?

A

2nd intercostal space just superior to the 3rd rib margin at midclavicular line

24
Q

What is the landmark for chest tube insertion?

A

4th intercostal space at mid or anterior axillary line just superior to margin of 5th rib

25
Q

What vertebral level should you see the lower margin of an endotrachal tube on an X-ray?

A

T4

26
Q

Landmark for thoracentesis?

A

7th intercostal space

27
Q

How would you monitor thoracic expansion?

A

Place thumbs at level of 10th ribs, have pt. inhale deeply, monitor for asymmetry

28
Q

Generalized hyper-resonance may be heard in what lung conditions?

A

COPD, asthma, emphysema.

29
Q

You are listening to a lung and notice that the bronchovesicular or bronchial breath sounds are heard further down than you would expect, what does this mean?

A

Suspect that air-filled lung has been replaced by fluid-filled or solid lung tissue

30
Q

Describe what crackles (rales) sound like; may occur after prolonged?

A
  • Discontinuous, intermittent, non-musical and brief
  • Sometimes likened to sound of “velcro”
  • May occur after prolonged recumbancy
31
Q

Describe what Wheezes sound like; suggest what kind of airways?

A
  • Continous; musical quality and prolonged
  • High pitched, hissing or shrill quality
  • Narrowed airways (asthma, COPD, bronchitis)
32
Q

Describe Rhonchi and what kind of airways?

A
  • Relatively low-pitched, snoring quality

- Secretions in large airways

33
Q

Describe Stridor and indicates?

A
  • Wheeze that is ENTIRELY/PREDOMINANTLY inspiratiory in nature
  • Partial obstruction of larynx or trachea (MEDICAL EMERGENCY!!!!!)
34
Q

Describe Pleural Friction Rub?

A
  • Inflamed/roughened pleural surfaces grate against eachother

Sounds like creaking, usually expiratory

35
Q

What are characteristics commonly seen in chronic bronchitis (the blue bloater)?

A
  • Overweight and cyanotic
  • Elevated hemoglobin
  • Peripheral edema
  • Rhonchi and wheezing
36
Q

What are the characteristics commonly seen in emphysema?

A
  • Older and thin
  • Severe dyspnea
  • Quiet chest
  • X-ray: hyperinflation w/ flatted diaphragm
37
Q

What is the pathological diagnosis of emphysema?

A

Permanent enlargement and destruction of airspace’s distal to the terminal bronchiole

38
Q

What is the clinical diagnosis for chronic bronchitis?

A

Daily productive cough for 3 months or more in at least 2 consecutive years

39
Q

Multiple rib fractures resulting in paradoxical movement of the throax is known as?

A

Flail chest

40
Q

What are kissmaul respiration’s indicative of?

A

Severe metabolic acidosis -> hyperventilation to reduce amount of CO2

41
Q

What is? Cheyne-Stokes respiration

A

A type of abnormal breathing characterized by a gradual increase in breathing, and then a decrease. This pattern is followed by a period of apnea where breathing temporarily stops. The cycle then repeats itself.

42
Q

If bronchovesicular or bronchial breath sounds are heard more distal than expected, what should you suspect?

A

Air-filled lung has been replaced by fluid-filled or solid lung tissue

43
Q

If you hear this adventitious breath sound, this indicates medical emergency!

A

Stridor! indicates partial obstruction of larynx or trachea

44
Q

Healthy resting adult respiratory rate?

A

14-20x per minute

45
Q

Which patients tend to sit leaning forward with shoulders elevated?

A

Patients with obstructive lung disorders

46
Q

What are the accessory muscle of neck for breathing?

A

Sternomastoid, scalenes, supraclavicular contraction

47
Q

What is involved in clubbing of the fingernails, vasculature wise?

A

Vasodilation with increased blood flow to the distal portion of the digits and change in CT possibly due to hypoxia, innervation, or platelet derived GF from fragments of platelet clumps
