Q

symmetric expansion

A

-Confirm symmetric chest expansion by placing your warmed hands on the posterolateral chest wall with thumbs at the level of T9 or T10.
-Slide your hands medially to pinch up a small fold of skin between your thumbs Ask the person to take a deep breath.
-Your hands serve as mechanical amplifiers; as the person inhales deeply, your thumbs should move apart symmetrically. Note any lag in expansion.

Q

how do you palpate for tactile fremitus

A

Use palmar base (ball) of fingers or ulnar edge of one hand
-touch person’s chest while he or she repeats words, “ninety-nine” or “blue moon.”
-Start over lung apices and palpate from one side to another
-symmetry is most important; vibrations should feel same on each side.
o-avoid palpating over scapulae because bone damps out sound transmission.

Q

where are bronchovesticular breath sounds heard?

A

Over major bronchi where fewer alveoli are located: posterior, between scapulae especially on right; anterior, around upper sternum in 1st and 2nd intercostal spaces

31
Q

vesicular breath sounds

soft, fine, breezy, low-pitched sounds

32
Q

where are vesicular breath sounds heard?

A

Over the peripheral lung fields

33
Q

adventitious sounds

A

Added sounds that are not normally heard in lungs

34
Q

adventitious sounds are caused by

A

moving air colliding with secretions in tracheobronchial passageways or by popping open of previously deflated airways

35
Q

adventitious sounds:classification and nomenclature of these sounds

A

crackles (or rales) and wheeze (or rhonchi) are terms commonly used by most examiners.

36
Q

Atelectatic crackles

A

a type of adventitious sound, is not pathologic; short, popping, crackling sounds that sound like fine crackles but do not last beyond a few breaths

37
Q

wheezes

A

Rhonchi

38
Q

crackles

A

rales

39
Q

Where are atelectatic crackles heard?

A

heard in the periphery only, and disappear after first few breaths or after a cough

40
Q

While ausculating voice sounds, Ask person to repeat what phrase while you listen over chest wall?

A

“ninety-nine”

41
Q

what do you normally hear while ausculating voice sounds

A

Normal voice transmission is soft, muffled, and indistinct; you can hear sound through stethoscope but cannot distinguish exactly what is being said.

42
Q

when ausculatating breath sounds, Progress from side to side as you move downward, and…

A

listen to one full respiration in each location.

43
Q

Auscultate lung fields over the

A

anterior chest from apices in supraclavicular areas down to sixth rib.

44
Q

A healthy person with no lung disease and no anemia normally has an SpO2 of

A

97% to 98%.
>95% is good

45
Q

what is a safer, simple, inexpensive, clinical measure of functional status in aging adults.

A

The 6-minute walk test (6 MWT)- checks if they are havinf SOB, whats their pulse ox?

46
Q

developmental competence of againg adult

A

o round barrel shape, and kyphosis or an outward curvature of thoracic spine.
o Chest expansion may be somewhat decreased, although still symmetric.
o Tend to tire easily during auscultation when deep mouth breathing is required

47
Q

thoracic diameter and barrel chest

A

shows an increased anteroposterior diameter

48
Q

developmental competence of acutely ill patient

A

-Use of a second examiner to assist the patient in terms of positional changes
-If no one is available, examiner may roll patient from side to side to facilitate change of position.
-If rolling technique is used, this may interfere with bilateral assessments of inspection and percussion.

49
Q

crepitus

A

crackling, crinkling, grating feeling under the skin (Rice crispies)

50
Q

Barrel chest

A

a condition characterized by increased anterior-posterior chest diameter caused by increased functional residual capacity due to air trapping from small airway collapse. A barrel chest is frequently seen in patients with chronic obstructive diseases, such as chronic bronchitis and emphysema.

51
Q

thorax and lung exam: inspection

A

Thoracic cage, respirations, skin color, and condition
o Person’s facial expression, and LOC

52
Q

thorax and lung exam: palpation

A

o Confirm symmetric expansion and tactile fremitus.
o Detection of any lumps, masses, or tenderness

53
Q

thorax and lung exam: auscultation

A

o Assess breath sounds, and note any abnormal/adventitious breath sounds.

54
Q

Pectus excavatum

A

sunken sternum and adjacent cartilages

55
Q

Pectus carinatum

A

a chest that protrudes like the keel of a ship

56
Q

Scoliosis

A

abnormal lateral curvature of the spine

57
Q

Kyphosis

A

hunchback

58
Q

Sigh

A

o Occasional sighs punctuate the normal breathing pattern and are purposeful to expand alveoli. Frequent signs may indicate emotional dysfunction and also may lead to hyperventilation and dizziness.

59
Q

Tachypnea

A

Rapid, shallow breathing. Increase rate.

60
Q

Bradypnea

A

o Slow breathing. A decreased but regular rate .

61
Q

Hyperventilation

A

Increase both rate and depth. Blows off CO2, causing decrease in the blood

62
Q

Hypoventilation

A

ventilation of the lungs that does not fulfill the body’s gas exchange needs; An irregular shallow pattern

63
Q

Cheyne-Stokes respiration

A

A cycle in which respirations gradually wax and wane in a regular pattern, increasing in rate and depth and then decreasing. The breathing periods last 30 to 45 seconds, with periods of apnea (20 seconds) alternating the cycle

64
Q

Biot’s respiration

A

Similar to Cheyne-Stokes respiration, except that the pattern is irregular. A series of normal respirations (3 to 4) is followed by a period of apnea. The cycle length is variable, lasting anywhere from 10 seconds to 1 minute.

65
Q

Chronic obstructive breathing

A

normal inspiration and prolonged expiration to overcome increased airway resistance

66
Q

Discontinuous sounds

A

o Crackles—fine
o Crackles—course
o Atelectatic crackles
o Pleural friction rub

67
Q

Continuous sounds

A

o Wheeze—sibilant
o Wheeze—sonorous rhonchi
o Stridor

68
Q

Crackles—fine

Discontinuous, high-pitched, short, crackling, popping sounds heard during inspiration that are not cleared by coughing.

69
Q

Crackles—course

A

Loud, low-pitch bubbling and gurgling sounds that start in early inspiration and may be present in expiration.

70
Q

Pleural friction rub

A

A very superficial sound that is coarse and low pitched; it has a grating quality as if two pieces of leather are being rubbed together. Sound is inspiratory and expiratory.

Low-pitched; monophonic, single note, musical snoring, moaning sounds. Heard throughout the cycle, although they are more prominent on expiration.

73
Q

Stridor

A

High-pitched, monophonic, inspiratory, crowing sound; louder in neck (pharynx/larnx) than over chest wall.
