1

What zone makes up the majority of the lung volume?

the respiratory zone

2

What structures are in the respiratory zone?

respiratory bronchioles, alveolar ducts, and alveolar sacs

3

What structures are in the conducting zone?

trachea, bronchi, bronchioles, and terminal bronchioles

4

What are the anatomical disease divisions of the respiratory system?

nasal and sinuses, upper airway, lower airway, parenchymal, and pleural space

5

What structures make up the upper airway?

pharynx, larynx, trachea, bronchi, and bronchioles

6

What structures make up the lower airway?

respiratory bronchioles and alveoli

7

It is best to auscultate the lungs in a _____ ____.

quiet room

8

How should a patient be positioned for auscultation?

standing, with the mouth closed

9

How do bronchial sounds sound?

harsh, hollow, and blowing

10

Where are bronchial sounds loudest?

over the trachea

11

Are bronchial sounds inspiratory or expiratory?

both

12

How do vesicular sounds sound?

rustling

13

Where are vesicular sounds made?

airflow through lobar bronchi - peripheral

14

Are vesicular sounds inspiratory or expiratory?

primarily inspiratory

15

What are the types of abnormal breath sounds?

crackles, wheezes, stertor, and stridor

16

What do crackles sound like?

discontinous popping sounds

17

What is the cause of crackles?

snapping open of small airways that have collapsed or accumulated fluid/debris

18

When is the timing of crackles?

during inspiration

19

How are crackles characterized?

moist vs. dry, and fine vs. course

20

What are the differentials for crackles?

pulmonary edema, pneumonia, or fibrosis (dry, stiff airways)

21

What do wheezes sound like?

continous, whistling musical sounds

22

What is the cause of wheezes?

airflow through constricted or narrowed airways

23

When is the timing of wheezes?

during expiration

24

What are the differentials for wheezes?

lower airway inflammatory disease or an anaphylactic reaction

25

What do stertor sounds sound like?

snoring, snorting, and snuffling noise that can be heard without a stethoscope

26

What is the cause of stertor?

upper airway obstruction of airflow due to excess tissue or secretions

27

When is the timing of stertor?

variable

28

Stertor suggests that diseases is located where?

in the nasal cavity and/or the nasopharynx

29

What are the differentials for stertor?

Brachycephalic syndrome, nasal congestion/infiltration, nasopharyngeal polyps, nasal/nasopharyngeal neoplasia, inflammatory/infectious rhinitis, and nasal/nasopharyngeal foreign body

30

What do stridor sounds sound like?

intense, high-pitched wheeze - shouldn't need a stethoscope
