With Verified Answers.
The vast majority of the total surface area of the lung is found in the:
- trachea
- segmental bronchi
- terminal bronchi
- alveoli - answer✔alveoli
All of the following can be measured via spirometry EXCEPT:
- tidal volume (TV)
- vital capacity (VC)
- functional residual capacity (FRC)
- inspiratory capacity (IC)
- expiratory reserve volume (ERV) - answer✔functional residual capacity (FRC)
Which of the following is a muscle that is used for expiration?
- sternocleidomastoid
- external obliques
- diaphragm
- external intercostals
- scalenus - answer✔external obliques
What is the Transpulmonary pressure (PTP) if pleural pressure is -7 cm H2O and alveolar
pressure is -3 cm H2O?
- +10 cm H2O
- 0 cm H2O - answer✔+4 cm H2O
A lung compliance test indicates that a 3 cm H2O change in transpulmonary pressure generates a
0.9 liter change in lung volume. What is this patient's lung compliance?
- 0.2 liters of air/cm H2O
- 0.2 cm H2O/liter of air
- 3.33 cm H2O/liter of air
- 0.3 liters of air/cm H2O
- 2.7 liters of air/cm H2O - answer✔0.3 liters of air/cm H2O
Airway resistance across a set of airways is lowest under which of the following conditions?
- airway radius is large and the length of the tube is large
- airway radius is large and the length of the tube is small
- airway radius is small and airways are in series.
- airway radius is small and airways are in parallel.
- airway radius is large and gas viscosity is increased - answer✔airway radius is large and the
length of the tube is small
As the lungs fill with air and we move from a low lung volume to higher lung volumes, airway
resistance will
- increase linearly
- decrease exponentially
- increase exponentially
- decrease linearly
- all of the above - answer✔decrease exponentially
A patient performs an expiratory forced vital capacity maneuver. His FVC is 2 liters and his
FEV1 is 1 liter. Based on your knowledge of these numbers you would predict that this person
suffers from
