Q

If you’re screening for lung cancer in people aged 55-80, but they have quit, long long ago should they have quit to decrease the need to do yearly screenings?

A

30 pack year history indicates screening, but if they have quit greater than 15 years ago, don’t need to screen anymore

Striae Moon Facies Buffalo Hump
27
What is the difference between dementia and delirium?
Dementia: chronic decline Delirium: acute and caused by something organic. reversible.
28
When pneumonia presents in older adult, will there typically be greater or fewer symptoms?
Fewer.
29
What is one symptom pneumonia may present with?
Delirium
30
Admitting older adults to the hospital for treatment of pneumonia is aways a good idea! Right?
Nope. most will have long standing loss of some degree so think twice about admitting.
31
Pneumonia is among the top 10 causes of death.
Yup. This wasn't a question, just know it's bad.
32
Do more people get pneumonia in nursing facilities or at home?
rate of occurance is highest in nursing facilities
33
Risk factors for pneumonia in elderly (Diseases-5)
``` Dementia Seizures CHF Cerebrovascular Ds COPD ```
34
Level of activity that is risk factor for pneumonia
inactivity
35
How does swallowing affect risk of pneumonia?
Increases
36
Does surgery or hospitalization affect risk of pneumonia?
yup. increases
37
Etiology of Community Acquired Pneumonia
exposure through contact with pathogen via normal living activities in non-special needs community
38
Etiology of Hospital/Nosocomial acquired pneumonia
exposure to pathogen while hospitalized
39
Etiology of pneumonia acquired in nursing home
exposure to pathogen while hospitalized
40
Do all geriatric patients present with typical fever, cough, malaise when they have pneumonia?
Nope, may just "not seem right"
41
What are some non-pulm symptoms of pneumonia in elderly?
``` N/V/D Mayalgia Arthralgia Confusion Falls General decline in over-all health Fatigue ```
42
What is the most common extra-pulmonary symptom of pneumonia in elderly?
fatigue
43
Pulmonary symptoms of pneumonia in elderly
cough SOB Sputum production Hemoptysis
44
What is the most common pulmonary symptom of pneumonia in elderly?
cough
45
PE findings for pneumonia? what are you expecting to find?
crackles wheezes dullness to percussion egophony
46
What does increase RR indicate in elderly
it's the most sensitive presentation of pneumonia in elderly
47
How long should you count to get an accurate RR?
30-60 seconds
48
Is RR valid if you count for 15 seconds?
No, only accurate if you count for 1 minute
49
What RR indicates severe pneumonia?
> 28
50
What will most people report or present with in pneumonia?
fatigue
51
How much of the >75 yo population has COPD?
10%
52
Is COPD adequately diagnosed and treated?
no, under dx and tx
53
What will SPO2 be doing in COPD?
it will be low. Might be first indication that something is wrong.
54
Areas that are affected by aging in respiratory function
structure, function, control
55
What happens to elastic recoil in aging?
goes down
56
Bronchiolar diameters ____ and alveolar ducts _____ (size)
Bronchiolar diameters diminish. Alveolar ducts enlarge
57
What does the change in bronchioles and alveoli result in?
decreased expiratory flow and decreased surface area for gas exchange
58
Advancing age = airways in dependent portions of lungs to close at higher volumes.
no idea what this means, but it's in the ppt.
59
What happens to costochondra cartilages?
they become calcified.
60
What does calcified constochondral cartilage lead to?
less lung expansion because the intercostal muscles shorten
61
Which parts of the immune system are dysregulated in aging?
adaptive and innate
62
What happens to cytokine production in aging?
increases
63
What disease process do cytokines play an integral role in?
COPD
64
The immune system response triggers a cascade of constant inflammation. COPD is though by some to be an autoimmune condition
This is in her ppt, but I think it's more food for thought than anything else.
65
How do you diagnose COPD in the older adult?
spirometry and history of exposure to noxious agents
66
Everyone being hospitalized for respiratory issues should have what?
CXR
67
If you suspect pneumonia, as a general rule for elderly patients, what blood tests should you order?
CBC and BMP. | Look at electrolytes
68
What's with the tongue?
look to see if it's dry
69
Is CT or CXR more sensitive for finding pneumonia?
CT
70
How does COPD present in the older adult?
Complicatedly. Might have SOB, fatigue, cough. OR Might have few or no respiratory complaints if they have other comorbidities
71
What happens to coughing as someone ages?
becomes less vigorous
72
Aging itself is though too be what kind of state?
inflammation. This adds to the difficulty of maintaining healthy lung function
73
What does spirometry measure?
lung function. measures volume and rate of air on inhalation and expiration
74
What could impact the validity of spirometry tests?
cognitive deficits or comorbidities that limit the patient's ability to perform the test or understand the instructions
75
What is the most commonly used PFT?
spirometry
76
What is the normal FEV1 value?
80-120%
77
What is the normal FVC value?
80-120%
78
How close should the FEV1/FVC ratio be to predicted ratio to be considered normal?
with in 5%
79
What is the TLC (total lung capacity) normal value?
80-120%
80
What is the normal FRC (functional residual capacity)?
75-120%
81
What does FVC stand for?
Forced vital capacity
82
How is spirometry performed?
Patient inhales maximally then exhales as rapidly and as completely as possible
83
How much of their volume can normal lungs expire in 6 seconds?
80%
84
Based on oximetry, when should you order O2?
if O2 Sat is
85
Arterial Blood Gas will show the arterial oxygen pressure (paO2). If it's below ___ patients should be given oxygen
60mmHg
86
Red flags during pulmonary exam in older patients (5)
``` crackles in base of lungs Cyanosis Markedly decreased exercise tolerance Severe fatigue "dad's just not himself" ```
87
What should you ALWAYS consider as a possible cause of respiratory symptoms?
cardiac pathology
88
What should you consider as a possible cause of delirium?
O2
