TEST BANK For Ruppel’s Manual of Pulmonary Function
Testing 12th Edition By Mottram
What measurements do PFT's provide? - ANSWER:They provide measurements of:
airway function and mechanics
lung volumes
gas exchange and cardiopulmonary exercise tolerance
What computerized equipment do most PFT labs have? - ANSWER:Spirometer
Body plethysmograph
Diffusion system
What are the indications for a PFT? Why do we need them? - ANSWER:Diagnostic
Monitoring
Disability
What are the Diagnostic uses of PFT's? - ANSWER:Evaluate symptoms, signs or
abnormal lab tests
Measure effect of disease on pulmonary function
Screen individuals at risk of having pulmonary disease
Assess pre-operative risk and/or health status prior to exercise program
What are the Monitoring uses of PFT's? - ANSWER:Assess the change in lung function
over time
Evaluate change after administration/change in drug therapy
Monitor for adverse reactions to drugs with know lung toxicity
Assess the potential effects of environmental/occupational exposures
What are the Disability uses oof PFT's? - ANSWER:Assess impairment of disability
from lung disease
Assess risks as part of insurance evaluation
What are contraindications of PFT's? Why wouldn't I do PFT's? - ANSWER:Myocardial
infarction within 1 month
Conditions where suboptimal lung function results are likely:
Chest or abdominal pain of any cause
Oral or facial pain exacerbated by a mouthpiece
Dementia or confused state
What are the patient preparation steps for a PFT? - ANSWER:Get Patient history
What arePresent symptoms/smoking history (packs x years=pack years)
What are Allergies, current medications, recent illnesses
Is there any history of pulmonary/cardiac diseases
Is there any General infor regarding the home and work envronment
Provide patient Instructions
, Is patient capable, both physically and mentally, of
full cooperation
Have they refrained from smoking for 4 hours,
drinking alcohol for 4 hours, eating a large meal
for 2 hours and exercise for 30 minutes
Is the patient wearing tight or form fitting clothing
Is the patient wearing dentures that can be left in place or
are they ill fitting and should be removed
How are predicted values determined for PFT's? - ANSWER:Age: lung volumes and
capacities decreas as a person ages
Gender: females have smaller lung volumes and capacities
Height: the taller the person, the larger the lung volumes and capacities
BSA: When used to predict and expected value-use ideal body weight
Race: Differences in lung volumes and capapcities are due to differences in body
proprotions and stature-race correction factors are used
What are the ranges for PFT results? - ANSWER:Normal: 80-120 % of predict value
Mild disorder: 60-79 %
Moderate disorder: 40 59%
Severe disorder: less than 40%
What is the formula for calculating % Predicted? - ANSWER:% Predicted=Measured
Value/Predicted Normal Value X 100
What are the 3 physiologic classifications of pulmonary disease? -
ANSWER:Obstructive diseases
Restrictive diseases
Combined diseases
What does routine PFT spirometry measure? - ANSWER:It measures to basic
components:
Volume
Flow
What does obstructive lung disease cause? - ANSWER:It causes reduced expiratory
flows
What does restrictive lung disease cause? - ANSWER:It causes reduced lung volumes
What does combined lung disease cause? - ANSWER:It causes both reduced
expiratory flow and reduced lung volumes
What are examples of Obstructive lung diseases? - ANSWER:Emphysema
Asthma
Acute/Chronic Bronchitis
Bronchiectasis
