NPTE FF - PULMONARY EXAM
QUESTIONS AND ANSWERS
Tidal Volume (TV) - Answer-Amount of air that moves in and out of the lungs during a
normal breath
500 mL - air inspired during normal, relaxed breathing.
10%
Inspiratory Reserve Volume (IRV) - Answer-Amount of air that can be forcefully inhaled
after a normal tidal volume inhalation
3,100 Ml- additional air that can
be forcibly inhaled after the inspiration of a normal tidal volume.
Inspired OVER n ABOVE tidal volume
50%
Expiratory Reserve Volume (ERV) - Answer-Amount of air that can be forcefully exhaled
after a normal tidal volume exhalation
1,200 mL- the additional air that
can be forcibly exhaled after the expiration of a normal tidal volume.
Expired OVER tidal volume
15%
Residual Volume (RV) - Answer-Amount of air remaining in the lungs after a forced
exhalation
1,200 mL- volume of air still remaining in thelungs after the expiratory reserve volume is
exhaled.
Always present in the lungs
25%
Total Lung Capacity (TLC) - Answer-maximum amount of air contained in lungs after a
maximum inspiratory effort
6,000 Ml- maximum amount of air that can
fill the lungs (TLC = TV + IRV + ERV + RV).
Vital Capacity (VC) - Answer-amount of air exhaled after a maximal inspiration
, 4,800 mL-total amount of air that can be expired after fully inhaling (VC = TV + IRV +
ERV = approximately 80 percent
TLC).
Inspiratory Capacity (IC) - Answer-the volume of air inhaled after a normal exhale
(IC) 3,600 mL- maximum amount of air that can be inspired (IC = TV + IRV).
Functional Residual Capacity (FRC) - Answer-volume of air remaining in the lungs after
a normal tidal volume expiration
2,400 mL- amount of air remaining
in the lungs after a normal expiration (FRC = RV + ERV).
A PT is performing spirometry to assess the lung
function of a patient with a diagnosis of COPD. The PT
tells the patient that he would like to assess the amount
of air in the lungs after a normal exhalation. What parameter is the PT referring to? -
Answer-FRC
A 58-year-old patient has chronic obstructive pulmonary disease. Which 3 pulmonary
test results will be increased when compared with those of a 58-year-old healthy
individual? What will decrease? - Answer-1. RV
2. FRC
3. TLC
FEV1/FVC Ratio will decrease
78-year-old patient was admitted with a diagnosis of acute exacerbation of COPD. The
patient has a FEV1 of 40% with FEV1/FVC <70% and has shortness of breathing during
ambulation. According to the GOLD classification, the patient would MOST likely be
classified as: - Answer-Severe
General patterns of symptoms for COPD - Answer-chronic cough
sputum
dyspnea
weight loss
R-sided HF
A 58-year-old patient has chronic obstructive pulmonary disease. During an
examination, a PT finds that a patient has a weak wet cough. What is MOST
appropriate to help this patient clear secretions? - Answer-Huffing
Not postural drainage if they don't give position !
