26
Q

Trachea and bronchi has dead space means?

A

Space that is filled with air but is not available for gaseous exchange (150mL in adult)

27
Q

Resp. function:

A

Supplies oxygen to the body for energy production.
Removes carbon dioxide as waste product of energy reactions.
Maintains homeostasis (acid-base balance).
Maintains heat exchange.

28
Q

Forced inspiration (after exercise or during pathology)—

A

use of accessory neck muscles to heave up sternum and rib cage (sternomastoids, scalene, trapezii)

29
Q

Forced expiration:

A

abdominal muscles contract to push abdominal viscera forcefully in and up against diaphragm, making it dome upward and squeeze against the lungs.

30
Q

Pregnant woman changes:

A

enlarging uterus elevates diaphragm.
Has a decreased vertical chest diameter,
compensatory increase in the horizontal diameter.
Increased estrogen—relaxes the chest cage ligaments.
Increased total chest circumference
Increased tidal volume to meet oxygen demands of fetus (deeper breathing; little change in RR)

31
Q

Physiologic dyspnea is:

A

in pregnancy: increased awareness of need to breathe.

32
Q

Changes in aging adult:

A

more rigid structure that is harder to inflate
Costal cartilages become calcified—thorax less mobile.
Respiratory muscle strength decreases.
Decreased elastic properties within lungs; lungs have less tendency to collapse and recoil.
Decreased vital capacity (max amount air that client can expel after first filling lungs to the max).
Increased residual volume (amount of air remaining in the lungs after forceful expiration).

33
Q

Elderly have increased risk for postoperative pulmonary complications because:

A

Decreased ability to cough
Loss of protective airway reflexes
Increased secretions

34
Q

What are the two major pulmonary diseases in which there are greater risks for races other than Whites?

A

TB, Asthma

35
Q

Ask about cough:

A

onset, frequency, duration, timing, productivity, self-care

36
Q

Ask about SOB:

A

onset, precipitating factors; ask about exposure to pets, pollen, food , exercise ?
affected by activity or position
Ask about associated factors—sweats, wheezing
Are there any alleviating factors?

37
Q

Ask about chest pain with breathing:

A

onset, duration, character (use PQRSTU)

38
Q

Ask about history of respiratory infections such as:

A

asthma, pneumonia, bronchitis, TB

39
Q

What are environmental conditions in Maine that might affect breathing?

A

^ smoking rate, environment/allergens, Mills?

40
Q

Ask about ___ in infants and children (Subjective data):

A

Frequency of URIs, allergies, noisy breathing.
Assess risk for FB aspiration, toxic ingestions.
Ask about exposure to secondhand smoke.

41
Q

Ask about aging adult (sub):

A

any new SOB or fatigue, reduced activity level, new immobility, weight change, falls, chest pain while breathing.

42
Q

Obj data: Inspection:

A

Assess facial expression to determine comfort of breathing.
Assess LOC, color and skin condition, quality of respirations, respiratory rate.
What position has client taken to breathe.
Look for symmetrical chest expansion.
What should be the relationship between the AP diameter and the transverse diameter?
How can scoliosis and kyphosis limit breathing?

43
Q

Obj data: Palpation:

A

for symmetric expansion, tactile fremitus.
Symmetric expansion—unequal with atelectasis, pneumonia, pleural effusion, fractured ribs, pneumothorax
Tactile fremitus—palpable vibration; “ninety-nine” side to side should be symmetrical (if not, investigate further).
Crepitus—palpate to determine if present.

44
Q

What is crepitus?

A

coarse, crackling sensation- palpable over the skin surface.
Abnormal finding: in subcutaneous emphysema when air escapes from the lung and enters the subcutaneous tissue (seen after open thoracic injury/surgery)

45
Q

Obj data: percussion:

A

Resonance—low-pitched, clear hollow sound over healthy lung tissue
Check for symmetry
Lower-pitched indicates more air (emphysema, pneumothorax)
Higher-pitched indicates increase in density (pneumonia)

46
Q

Obj data: Auscultation:

A

Breath sounds—bronchial (tracheal or tubular); bronchovesicular; vesicular

47
Q

Why can’t you listen to breath sounds just anteriorly or posteriorly?

A

missing the lobe on the side of the body

48
Q

Decreased or absent breath sounds caused by:

A

Bronchial tree obstruction—by what?
Decreased force of inspired air
Hyperinflation
Obstruction between lung and stethoscope

49
Q

Adventitious sounds
 is:

A

Crackles—inspiration

Wheezes—mainly expiration

50
Q

Describe breath sounds by these characteristics:

A

On inspiration or on expiration
Loudness
Pitch
Location on chest wall

51
Q

Spirometer measures:

A

FEV (forced expiratory volume)

52
Q

6-minute walk test (6 MWT):

A

A person who walks >300 meters in 6 minutes is more likely to engage in activities of daily living.

53
Q

Infant/child chest diameter:

A

has an equal AP to transverse chest diameter; by age 6, reaches adult ration of 1:2 (AP-to-transverse diameter)

54
Q

Slight flaring of lower costal margins may occur with ____ ?

A

respirations.

55
Q

Should see no ___, ___, ___ in infants/child?

A

NO nasal flaring, sternal retraction, intercostal retraction.

56
Q

A newborn’s major respiratory muscle is the

A

diaphragm

57
Q

intercostal muscles are not well developed in the?

A

newborn

58
Q

______ will bulge with each inspiration; there will be little ______ expansion in infant/child.

A

abdomen, thoracic

59
Q

Infants breathe at ___-___ respirations/minute.

A

30-40

60
Q

Up to age ___-___, will hear bronchovesicular breath sounds in peripheral lung fields; breath sounds are louder and harsher.

A

5-6

61
Q

Stridor is:

A

high-pitched inspiratory crowing sound; indicates upper airway obstruction (croup, foreign body aspiration, acute epiglottis).

62
Q

Increased AP diameter is called:

A

barrel chest

63

If kyphosis present, will compensate by:

A

extending and tilting back head.

64
