25
risk factors for developing sleep apnea
obesity, male gender, postmenopausal status, advanced age
26
clinical manifestations of OSA
3 S's- snoring sleepiness, significant other reporting sleep apnea episodes; chronic fatigue, hypersomnolence (daytime sleepiness); awakening at night and unable to return to sleep
27
management of sleep apnea
diagnosed with sleep study; mandibular advancement device are first step; CPAP/BiPAP are second or alternative option; surgeries like tonsillectomy to create more space, uvulopalatopharyngoplasty (reconstruction), or nasal septoplasty
28
CPAP vs BiPAP
CPAP- continuous positive airway pressure- keeps airway from collapsing; BiPAP- bilevel positive airway pressure- makes breathing easier and results in lower average airway pressure
29
epistaxis
rupture or distended vessels in mucous membrane of nose (commonly anterior septum)
30
management of epistaxis
sit pt upright with head tilting forward (to prevent swallowing/aspiration of blood) and pinch soft outer nose at mid septum for 5-10 minutes; prolonged bleeding may require nasal decongestants to vasoconstrict; if both ineffective then cauterization
31
if cause of epistaxis cannot be identified...
nose is packed with impregnated gauze and may remain in nose for 3-4 days; antibx may be prescribed
32
education for pt with epistaxis
avoid exercise, spicy foods, smoking tobacco, blowing nose, straining, high altitudes, nasal trauma; instruct pt to call if recurrrent bleed cannot be stopped after 15 minutes of pressure
33
lower respiratory infections
pneumonia, influenza, COVID-19, tuberculosis
34
pneumonia
infection of pulmonary tissue (bacterial, viral, or fungal); inflammatory edema stiffens lung, decreases compliance and capacity to cause hypoxemia; community acquired or healthcare associated
35
community acquired pneumonia
rate increases with age, bacterial- S.pneumoniae is most common, viral- RSV or COVID-19
36
healthcare associated pneumonia
48+ hours post hospitalization and often caused by MDROs (multi drug resistant organisms)
37
clinical manifestations of pneumonia
CXR shows consolidation, infiltrates, or pleural effusion, elevated WBCs and ESR, fever, chills, cough, dyspnea, tachypnea, rhonchi/wheezing, pleuritic pain, sputum production (culture needed to identify cause), mental status changes
38
management of pneumonia
oxygen therapy, antibx, supportive care meds; monitor resp. status for signs of distress; encourage cough/deep breathing/incentive spirometer; place in semi-fowlers and change position frequently; suction if unable to clear secretions; encourage fluid intake, high cal/high protein diet, balance rest and activity; should receive pneumococcal vaccine as recommended
39
influenza
highly contagious acute viral infection with several strains (A, B, C, H1N1); prevention is key
40
ways to prevent influenza
annual vaccine, avoiding infected people, frequent and proper handwashing, cleaning and disinfecting contaminated surfaces
41
clinical manifestations of influenza
acute onset, fever, myalgias (pain/aches), headache, fatigue/weakness/anorexia, sore throat/cough, rhinorrhea
42
management of influenza
supportive care measures- rest, fluids, antipyretics, antitussives; administer antiviral meds as prescribed (tamiflu within 48 hours)
43
COVID-19
infectious respiratory illness caused by novel coronavirus SARS-CoV-2; primarily spreads via respiratory droplets (cough sneeze or close contact); incubation period usually 2-14 days
44
clinical manifestations of COVID-19
common- fever, cough, SOB, fatigue, aches, loss of smell/taste; less common- sore throat, headache, chills, GI symptoms; severe symptoms- pneumonia, ARDS, organ failure; some individuals are asymptomatic
45
COVID-19 diagnosis/management
based on symptoms, history, and lab resuls (PCR/antigen test); supportive care; severe cases may require hospitalization for O2 therapy, ventilator support; antiviral meds may be indicated (nirmatrelvir-ritonavir) and must be administered within 5 days of symptom onset; COVID vaccines are vital in preventing severe illness/transmission
46
antiviral should be reserved for...
those individuals who cannot handle the virus
47
COVID-19 nursing interventions
infection prevention (hand hygiene, masks, PPE), isolation precautions (droplet, airborne, contact), respiratory support, emotional support, health education, monitoring and reporting
48
Tubeculosis
highly contagious communicable disease caused by M. tuberculosis; airborne, exudative response causes nonspecific pneumonitis and granulomas in lung tissue; onset is insidious and pt are unaware until disease is advanced
49
tuberculosis causes
bacteria forms tubercle lesion and immune system encapsulates tubercle leaving a scar; if no encapsulation then bacteria can enter lymph and cause inflammatory response called granulomatous inflammation leading to primary lesions forming
50
active phase of TB
infection causes necrosis and cavitation in lesions that can rupture and spread necrotic tissue damaging various parts of body; need Xray to confirm because recent BCG vaccine causes positive skin test (mantioux/PPD)
51
risk factors for developing TB
12- elderly, <5 years old, unpasteurized milk if cow infected, homeless, low socieoconomic group, minorities, refugees, frequent contact with untreated/undiagnosed individual, those in crowded living areas, malnutrition, immune dysfunction, alcohol abuse/IV drug use
52
clinical manifestations of TB
may be asymptomatic in primary phase, fatigue, lethargy, anorexia, weight loss, low grade fever, chills, night sweats, persistent cough (can be blood streaked but usually dry), chest tightness, dull aching chest pain with cough
53
testing for TB
CXR may show caseation and inflammation, advanced may show partial obstruction of bronchus from endobronchial disease (wheezing and dyspnea present), TB skin test (positive result does not mean active), quantiferon TB gold test (sensitive and rapid blood test), sputum culture to confirm
54
managing TB
goal is to prevent transmission, reduce symptoms, and prevent progression; risk of transmission decreases after 2-3 weeks of treatment, treatment for up to 12 months, educate importance on compliance; well balanced diet; sputum culture every 2-4 week until 3 negative test consecutively
55
chronic pulmonary disorders
asthma, COPD, cystic fibrosis
56
asthma
chronic inflammatory disorder of airways causing varying degrees of obstruction; marked by hyperresponsiveness to stimuli, bronchioole inflammation, bronchoconstriction, mucus production; often reversible with treatment
57
status asthmaticus

58
clinical manifestations of asthma
wheezing or crackles, absent/diminished lug sounds, restlessness, diaphoresis, cyanosis, decreased O2 sat., accessory muscle use, tachypnea/hyperventilation, prolonged exhalation, tachycardia
59
management of acute asthma attack
monitor vitals (O2 sat and peak flow), high fowlers, administer O2, stay with client to decrease O2, administer bronchodilators corticosteroids and ag. sulfate, auscultate lung sounds before during and after treatment
60
IV Magnesium sulfate works
by further dilating bronchioles and relaxes muscles
61
cystsic fibrosis
chronic multisystem autosomal recessive trait disorder characterized by exocrine gland dysfunction; progressive and incurable; mucus produced by exocrine glands is abnormally thick tenacious and copious causing obstruction of small passageways of affected organs
62
organsprimarily affected by CF

63
diagnosing CF
positive chloride sweat test; increased sodium and chloride in sweat/saliva

66
medications for CF
bronchodilators and meds to decrease viscocity of mucus such as pulmozyne or 7% N.S.
67
treatment of CF
chest physiotherapy, flutter mucus clearing device, handheld percussors, special vest device, positive expiratory pressure mask (CPAP)
68
chronic obstructive pulmonary disease
characterized by airflow obstruction- emphysema and chronic bronchitis; both are caused by tobacco smoke; both lead to pulmonary insufficiency, pulmonary HTN, cor pulmonale; not completely reversible
69
chronic bronchitis
productive cough >3 months at a time for more than two consecutive years; bronchial tubes become inflamed and excessive mucus production occurs, "blue bloater", causes peripheral edema
70
emphysema
air sacs are damaged and enlarged causing hyperinflation and breathlessness; "pink puffer", barrel chest
71
clinical manifestations of COPD
cough, exertional dyspnea, wheezing/crackles, sputum production, weight loss, barrel chest, accessory muscle use, prolonged expiration, orthopnea, cardiac dysrhythmias, congestion/hyperinflation on CXR, ABG show acidosis and hypoxemia, decreased capacity on PFT
72
cor pulmonale
vasoconstriction in one part of the lung causing blood to shunt to another area of lung but pressure is increased in that area
73
managing COPD
monitor vitals (O2 sat., ABG), admin O2, fowlers position and leaning forward, respiratory treatments and CPT, educate on tripod breathing and pursed lip breathing, bronchodilators, corticosteroids, mucolytics, antibiotics, high cal/high protein diet with 2-3L fluids, suction as needed
74
lower respiratory conditions
atelectasis, pleural effusion, empyema, pleurisy, aspiration
75
atelectasis
collapse of alveoli; can be acute or chronic; occurs as a result of ventilation; can be caused by reduced ventilation or obstruction; post-op pt at high risk

78
prevention of atelectasis
frequent turning, early ambulation, lung volume expansion maneuvers (deep breathing/incentive spirometer), positive end respiratory pressure (PEEP), CPAP
79
pleural effusion
collection of fluid in pleural space; any condition that interferes with secretion or drainage will lead to pleural effusion
80
clinical manifestations of pleural effusion
pleuritic pain that worsens with inspiration, progressive dyspnea, nonproductive cough, tachycardia, possible fever, decreased breath sounds over affected area, shown on CXR
81
management of pleural effusion
treat underlying cause, fowlers position, encourage coughing/deep breaths, monitor lung sounds, prep for thoracentesis, if recurrent then prep for pleurectomy or pleurodesis

inflammation of visceral and parietal membranes; caused by pulmonary infarction or pneumonia; visceral and parietal membranes rube during respiration and cause pain; usually only on one side and lower lateral region
86
clinical manifestations of pleurisy
stabbing pain that worsens during cough or deep breathing; pleural friction rub auscultated
87
management of pleurisy
treat underlying cause, monitor lung sounds, administer analgesics, apply heat/cold, encourage cough and deep breath with chest splinting
