BIO 669 SECTION 3 EXAM QUESTIONS
AND ANSWERS UPDATED (2024/2025)
(VERIFIED ANSWERS)
The pores of Kohn play a role in: - ANS ✓Allowing air to pass from one alveoli
to another, allowing equal distribution of air
Severe bronchospasm not responsive to the normal measures (beta agonist
bronchodilators) is best described as: - ANS ✓Status asthmaticus
Widespread pulmonary fibrosis, edema and subsequent hypoxemia will
most likely result in: - ANS ✓Pulmonary hypertension
Which of the following statements about pneumonia is INCORRECT? - ANS
✓Pneumonia is an upper respiratory tract infection
Your patient presents with acute onset and worsening of chest pain,
dyspnea, mediastinal shift on x-ray and tachypnea. The most likely
diagnostic fit for this patient's presentation is: - ANS ✓Tension
pneumothorax

Ventilation that increase in volume until a peak, followed by decrease
volumes until a period of apnea occurs then repeats is best described as
what breathing pattern? - ANS ✓Cheyne-Stokes respirations
Which of the following is true of the pathophysiology of asthma? - ANS
✓Inflammation results in hyper responsiveness
The main neural control center coordination ventilation during quiet
breathing is the - ANS ✓Dorsal respiratory group
Vital capacity is comprised of all of the following EXCEPT: - ANS ✓Residual
volume
How is alveolar volume measured? - ANS ✓Indirectly by measuring the PaO2
or PaCO2
Vasoconstriction of a pulmonary artery serving an area of lungs will all
have what effect? - ANS ✓Decreased blood flow to that area
Which of the following statements is INCORRECT regarding tuberculosis? -
ANS ✓TB typically presents as an acute onset and rapidly advancing disease
process

Empyema results from - ANS ✓An infected pleural effusion
The amount of air remaining in the lungs after a complete, forceful
exhalation is termed the: - ANS ✓Residual volume
Which of the following muscles is NOT associated with inspiration? - ANS
✓Internal intercostals
What helps to keep the expansion forces of the chest wall and the
contracting forces of the alveoli/lungs linked so that the lung does not
collapse and chest does not expand further? - ANS ✓The negative pressure of
the pleural cavity
While most alveolar perfusion is under the control of local humoral
conditions, widespread decrease in PaO2 (alveolar O2) is likely to result in:
- ANS ✓Pulmonary artery constriction (pulmonary hypertension)
All of the following are findings consistent with pulmonary fibrosis EXCEPT:
- ANS ✓Increased lung compliance
What happens to the functional residual capacity in COPD? - ANS ✓It
increases, resting the TV to a higher volume
