RCP 140 CHAPTER 4 QUESTIONS AND ANSWERS
1. Evaluate causes of dyspnea
2. Differentiate between restrictive and obstructive disorders
3. Assess severity of disease
4. Evaluate effectiveness of therapy - Answers - The result of pulmonary function test
are used for the following:
1. Tidal volume (VT)
2. Inspiratory reserve (IRV)
3. Expiratory reserve (ERV)
4. Residual volume (RV) - Answers - (PFT) The four lung volumes:
1. Vital capacity (VC)
2. Inspiratory capacity (IC)
3. Functional Residual Capacity (FRC)
4. Total Lung Capacity (TLC) - Answers - (PFT) The four lung capacities:
Tidal volume (VT) - Answers - Amount of gas that moves in and out of the lungs in one
breath.
Inspiratory reserve (IRV) - Answers - Volume of air that can be forcefully inspired after a
normal tidal volume.
Expiratory reserve (ERV) - Answers - Volume of air that can be forcefully exhaled after
normal exhalation.
Residual volume (RV) - Answers - Air remaining in lungs after a force exhalation.
Vital capacity (VC) - Answers - Volume of air exhaled after a maximal inspiration
Inspiratory capacity (IC) - Answers - Volume of air inhaled after a normal exhalation
Functional Residual Capacity (FRC) - Answers - Lung volume at rest after a normal tidal
volume exhalation.
Total Lung Capacity (TLC) - Answers - Maximal amount of air the lungs can
accommodate.
ERV+ RV - Answers - Functional Residual Capacity (FRC) = (lung volumes)
IC+ERV+RV - Answers - Total Lung Capacity (TLC) = (lung volumes)
VT+ IRV - Answers - Inspiratory capacity (IC) = (lung volumes)
