Respiratory System

Question 1

Adventitious Breath Sounds

Answer 1

Breath sounds not normally heard in the lungs

Question 2

Stridor

Answer 2

Harsh, high pitched sound heard on inspiration related to narrowing of the upper airway

Question 3

Crackles

Answer 3

Fine to course crackling sound as air moves through wet secretions, heard on inspiration

Question 4

Rhonchi

Answer 4

Coarse sounds that are low-pitched, heard on inspiration or expiration originating in small air passages that are narrowed.

Question 5

Wheezes

Answer 5

High piched sounds, musical or squeaking heard on inspiration or expiration originating in small air passages that are narrowed.

Question 6

Pleural Friction Rub

Answer 6

Grating sound caused by an inflamed pleura rubbing against the chest wall, heard more often on inspiration and not changed by coughing

Question 7

Apnea

Answer 7

Absence of breathing

Question 8

Bradypnea

Answer 8

Respiration’s that are regular in rhythm but slower than normal in rate. Abnormally slow rate of breathing–less than 12 respiration’s per minute.

Question 9

Breath sounds

Answer 9

breath sounds result from the free movement of air into and out of all parts of the bronchial tree. Listen for duration, pitch and intensity of the sounds.

Question 10

Bronchial sounds

Answer 10

Normal breath sounds which are high pitched and harsh heard over the trachea with expiration longer than inspiration.

Question 11

Bronchovesicular sounds

Answer 11

normal breath sounds which are moderate blowing sounds heard over the mainstem bronchus with inspiration equal to expiration.

Question 12

Vesicular Sounds

Answer 12

normal breath sounds which are soft, low-pitched sounds heard best over the base of the lungs during inspiration which is longer than expiration

Question 13

COPD

Chronic Obstructive Pulmonary Disease

Answer 13

Chronic condition of persistent obstruction of bronchial air flow. Chronic bronchitis and chronic pulmonary emphysema are the diseases mainly associated with this condition.

Question 14

Dyspnea

Answer 14

Labored or difficult breathing

Question 15

Eupnea

Answer 15

Normal respiration’s Rate 12-20 respiration’s per minute

Question 16

Fremitus

Answer 16

Vibration felt on palpation

Question 17

Hyperresonance

Answer 17

The sound produced when percussion is performed over lung tissue affected by emphysema

Question 18

Hypoventilation

Answer 18

A decrease in the rate or depth of air movement into the lungs which often causes hypoxia.

Question 19

Hypoxia

Answer 19

a condition in which an inadequate amount of oxygen is available to the cells. It is a problem with ventilation, respiration, or perfusion

Question 20

lower airway

Answer 20

consists of trachea, right and left main stem bronchi, segmental bronchi, and terminal bronchioles. main function is the conduction of air, mucociliary clearance, and production of pulmonary surfactant.

Question 21

orthopnea

Answer 21

Ability to breathe easily only in the upright position

Question 22

perfusion

Answer 22

the process wherein oxygenated capillary blood passes through tissue.

Question 23

pulse oximetry

Answer 23

measuring oxygen saturation of arterial blood. A pusle oximetry of 95%-100% is normal.

Question 24

pursed-lip breathing

Answer 24

a breathing exercise used for patients who experience dyspnea and feelings of panic. Patient inhales through the nose and exhales slowly and evenly against pursed lips. (lips are positioned as if blowing through a straw or whistling)

Question 25

Resonance

Answer 25

The sound produced over normal air-filled lungs when percussion is performed

Question 26

Respirations

Answer 26

The exchange of oxygen and carbon dioxide between the atmosphere and the body cells

Question 27

Tachypnea

Answer 27

very rapid respirations

Question 28

Upper airway

Answer 28

consist of the nose, pharynx, larynx, and epiglottis. Main function is to warm, filter, and humidify inspired air.

Question 29

ventilation

Answer 29

the movement of air into and out of the lungs.
