UNIT 4 EDAPT: OBSTRUCTIVE AND
RESTRICTIVE LUNG DISEASES EXAM
QUESTIONS AND ANSWERS
ASTHMA -ANSThe NP notes that a patient's FEV1/FVC ratio is severely reduced.
Which condition is most likely the patient's pulmonary issue?
ASTHMA -ANSAN example of an obstructive disease
REDUCED (<70%) FEV1/FVC RATIO -ANSautomatically points to obstructive disease
The FEV1/FVC ratio -ANSa measure of the percentage of a patient's vital capacity that
can be expired in the first second of expiration
restrictive LUNG disease -ANSThe NP reviews the results of a patient's pulmonary
function tests and notes that the FEV1, FVC, and total lung capacity (TLC) are reduced.
The FEV1/FVC ratio is normal. Based on interpretation, this reflects:
RESTRICTVE LUNG DISEASE -ANSthe FEV1, FVC and TLC are all reduced this
indicates:
obstructive problem. -ANSA normal FEV1/FVC ratio is a clue that this is not a(n)
80 -ANSThe normal range for the FEV1/FVC is _____%.
80%; second -ANSa pt w norm lungs should be able to exhale _____ of forced vital
capacity within the first ____
Decreased forced expiratory flow (FEV1). -ANSWhat pulmonary function test (PFT)
findings are anticipated based on the diagnosis of chronic bronchitis?
obstructive -ANSwhat kind of disease is chronic bronchitis?
decreased -ANSobstructive diseases lead to ___ expiratory flow rates and FEV1
air trapping -ANScommon in obstructive disease which will cause an increased TLC.
decreased diffusing capacity -ANStypically only occurs in emphysema, not chronic
bronchitis.
, residual volume-Since that volume cannot be exhaled, it cannot be measure. -ANSwhat
can simple spirometry NOT measure
Inspiratory reserve volume, tidal volume, vital capacity -ANSwhat 3 things can simple
spirometry measure
Residual volume -ANSthe amount of air that is left in the lungs after a full exhalation. it
cannot be measure.
Spirometry -ANSSpirometry
Pulmonary function tests (PFTs) -ANSnon-invasive tests that provide information about
lung function; alone cannot differentiate among the causes of respiratory abnormalities.
Therefore, the patient's history, physical exam and other diagnostics must be
considered when making a diagnosis; can help the NP determine the patient's
respiratory pattern, specifically if the abnormality is due to an obstructive or restrictive
problem. Once the pattern is identified, these allow the NP to determine the severity of
the disease. This data combined with other patient findings, leads to a diagnosis.
indications to help the NP to determine when to order PFTs -ANSWhen signs and
symptoms of a respiratory problem requires evaluation (cough, dyspnea, cyanosis,
wheezing, hypoxemia, hypercapnia and lung hyperinflation).
When disease progression needs to be determined.
When monitoring the effectiveness of drug therapy.
When monitoring for potential toxic effects of certain drugs.
spirometry. diffusing capacity, residual volume (RV) and total lung capactiy (TLC) -
ANS4 components of pulmonary function tests
spirometry -ANSa component of PFTs; this measures air movement in & out of lungs
during various respiratory maneuvers
Forced vital capacity (FVC), Forced expiratory volume in 1 second (FEV1), FEV1/FVC
ratio -ANSthree results of spirometry
Forced vital capacity (FVC), & forced expiratory volume in 1 second (FEV1) -
ANSnormal is 80-120% (2)
Forced vital capacity (FVC) -ANSa result of spirometry that measures the volume of air
in the lungs that can be exhaled; client inhales as deep as possible and then exhales as
long and as forcefully as possible
normal is 80-120%
