GMS6402: Medical Pulmonary Physiology EXAM
(2025/2026) Updated: EXAM QUESTIONS WITH
ACCURATE ANSWERS | GET IT RIGHT!!
The vast majority of the total surface area of the lung is found in the -
(ANSWER)alveoli
All of the following can be measured via spirometry except - (ANSWER)Functional
residual capacity (FRC)
What is the muscle that is used for expiration? - (ANSWER)External obliques
What is the transpulmonary pressure if pleural pressure is -7 cm H2O and alveolar
pressure is -3 cm H2O? - (ANSWER)+4 cm H2O
Lung compliance test indicates that a 3 cm H2O change in transpulmonary
pressure generates a 0.9 L change in lung volume. What is this patient's lung
compliance? - (ANSWER)0.3 L of air/cm H2O
Airway resistance across a set of airways is lowest under what conditions? -
(ANSWER)Airway radius is large and length of the tube is small
As the lungs fill with air and we move from a low lung volume to a higher lung
volume, airway resistance will - (ANSWER)Decrease exponentially
, A patient performs an expiratory forced vital capacity maneuver. His FVC is 2 L
and his FEV1 is 1 L. Based on these numbers, you would predict this patient
suffers from what? - (ANSWER)Obstructive lung disease
When at sea level and breathing room air, the partial pressure of O2 in inspired
air is what? - (ANSWER)160 mmHg
A patient begins to hyperventilate while sitting in a clinic on Miami Beach and
breathing room air. Over the ensuing 1 minute, his PaCO2 drops to 20 mmHg.
What is his PaO2 at that moment in time? - (ANSWER)125 mmHg
With respect to the path of O2 diffusion, the proper order for the movement of
oxygen across the pulmonary capillary membrane is - (ANSWER)alveolar
epithelium, interstitial space, capillary basement membrane, blood
When a gas in the blood such as oxygen fails to reach diffusion equilibrium with
the alveolar air as it leaves the pulmonary capillary bed is said to be -
(ANSWER)diffusion limited
Under normal physiological conditions, the max capacity of O2 that Hb can carry
is approx: - (ANSWER)200 mL per day
Which of the following will increase the content of arterial oxygen -
(ANSWER)increased hemoglobin concentration
