drainage from a chest tube should be no more than ___________ and should be checked _________-

A

100ml/hr; hourly

36
Q

drainage from a chest tube should be (characteristics)

37
Q

If the chest tube comes out of the pt

cover site with sterile dressing and tape on 3 sides

38
Q

if the chest tube disconnects from the drainage system

A

place end of tube in bottle of sterile water

39
Q

bronchodilators

A

bind to beta2 adrenergic receptors in the airway leading to relaxation of the smooth muscles in the airways

40
Q

bronchodilators can cause

A

tachycardia

41
Q

use caution when administering bronchodilators to pts with

A

heart disease, diabetes, glaucoma, or seizures

42
Q

Bronchodilator examples

A

albuterol, terbutaline, ipratropium

43
Q

side effects of terbutaline includes

A

shakiness, dizziness, drowsiness, sleep disturbances, weakness, headache, n/v, tachycardia, htn, hyperglycemia, CNS overstimulation

44
Q

montelukast

A

leukotriene modifier: long term control medication, helps prevent/control flare ups of allergic rhinits, allergies, asthma

45
Q

guaifenesin

A

expectorant; loosens up mucus and stimulates cough to get mucus out of respiratory tract

46
Q

acetylcysteine

A

mucolytic; breaks up mucus to get rid of it

47
Q

pseudophedrine, phenylephrine

A

decongestant; work on CVS system; capillaries in nasal passages and cause vasoconstriction which reduces edema leading to decongestion

48
Q

antitussives

A

dextromethorphan, codeine; cough medications, suppress the cough reflex

49
Q

methylprenisolone

A

steroid to reduce inflammations and suppress normal immune response

50
Q

too much steroid can cause

A

cushing’s symptoms

51
Q

Side effects of steroids

A

immunosuppression, hyperglycemia, osteoporosis, delayed wound healing

52
Q

antihistamines 2 types

A

histamine 1 blocker and histamine 2 blocker

53
Q

histamine 1 blockers and example

A

block H1 receptors in CNS -> stop allergies; used in resp system as blocking the CNS receptors cause depression of symptoms
example) diphenhydramine

54
Q

histamine 2 blockers and example

A

blocks production of stomach acid
example) famotidine, ranitidine

55
Q

diphenhydramine has anticholinergic effects which include

A

drying the body up, urinary retention, constipation

56
Q

COPD

A

group of lung diseases that block airflow and make it difficult to breathe; includes emphysema, chronic bronchitis, asthma

57
Q

emphysema

A

destruction of the alveoli due to chronic inflammation; decreased surface area of alveoli for gas exchange

58
Q

chronic bronchitis

A

chronic inflammation with a productive cough and excessive sputuma

59
Q

asthma

A

respiratory condition marked by spasms in the bronchi of the lungs causing difficulty in breathing - chronic inflammation of the bronchi and bronchioles and excess mucus

60
Q

COPD assessment findings

A

barrel chest
accessory muscle use
congestion
lung sounds diminished, crackles, wheezes
acidotic, hypercarbic, hypoxic

61
Q

explanation of ABGs in COPD pt

A

CO2 increases because air is being retained = hypercarbic, CO2 is an acid so they become acidotic; poor gas exchange due to surface area of alveoli decreasing leads to hypoxia

62
Q

COPD treatment

A

oxygen (carefully), bronchodilator, chest physio, increase fluid intake, pursed lip breathing, small frequent meals

63
Q

in a normal pt ___________ stimulates the body to breathe, but in COPD pts __________ is the driving factor to breathe because

A

hypercarbia; hypoxia; because they have been hypercarbic for an extended period of time

64
Q

asthma has to have a

A

trigger

65
Q

acute asthma exacerbation treatment

A

open up airway (albuterol? intubation?), O2 admin followed by bronchodilator, anticholinergic, steroid, IV fluids

66
Q

status asthmaticus

A

asthma attack that is refractory to treatment and leads to severe respiratory failure; will intubate to keep airway open (may give magnesium sulfate to vasodilate and sedation to help relax muscles)

67
Q

pneumonia

A

inflammation of the lung affecting alveoli, they become filled with pus and liquid

68
Q

diagnosis of pneumonia

A

CXR (patchy infiltrates), sputum culture

69
Q

pneumonia S&S

A

high fever, cough, tachypnea, crackles, chest pain, increased work of breathing

70
Q

Acute respiratory distress syndrome

A

characterized by bilateral pulmonary infiltrates and severe hypoxemia in absence of any cardiac relation

71
Q

ABGs in a pt with ARDS will show

A

respiratory acidosis; due to impaired gas exchange

72
Q

damage to the lungs from ARDS is reversible or irreversible

A

irreversible

73
Q

ARDS causes an increase in capillary membrane permeability which means

A

the cells spread out causing fluid to leak into alveoli leading to poor gas exchange

74
Q

causes of ARDS

A

anything that causes an inflammatory reaction in the lungs (trauma, sepsis, burns, aspiration pneumonia, overdose, near drowning)

75
Q

Diagnosis of ARDS

A

CXR showing diffuse bilateral infiltrates, hypoxemia; pale, cool, mottles, low SpO2

76
Q

treatments for ARDS

A

treat underlying condition, intubation and mechanical ventilation, prone, prevent infection (VAP), prevent barotrauma (too much pressure to alveoli)

77
Q

spontaneous pneumothorax occur due to a

A

disease process

78
Q

Pneumothorax S&S

A

SOB, chest pain, desaturation, hypotension, tachycardia, tracheal deviation?

79
Q

tension pneumothorax

A

air goes into lungs and leaks into pleural space where it then accumulates, it pushes on the lungs, trachea, and heart causing the trachea to shift

80
Q

pulmonary embolism

A

blood clot in lungs, causing hypoxemia

81
Q

pulmonary embolism can lead to _______ sided HF if untreated

A

right

82
Q

Pulmonary embolism S&S

A

dyspnea, chest pain, anxiety, hypoxemia, rales, diaphoresis, hemoptysis

A

O2 admin, high fowlers, anticoagulants, thrombolytics

84
