INTRODUCTION
This comprehensive study guide is designed for NRMS 5190 Advanced
Pathophysiology Exam 2 at SUNY Downstate Medical Center. It
synthesizes the most frequently tested concepts from respiratory,
cardiovascular, renal, neurologic, and endocrine pathophysiology, as well
as pediatric developmental assessment and complex genetic disorders.
The guide employs multiple-choice and case-based questions with detailed
rationales to simulate the rigor of the proctored exam. Emphasis is placed
on mechanism-based reasoning, data interpretation, and clinical
application. This resource prepares candidates for the 2026/2027 exam
update and supports mastery of advanced pathophysiologic principles.
SECTION ONE: QUESTIONS 1–100
1. Which alveolar cell type produces surfactant that reduces surface
tension and increases lung compliance?
A. Bronchial smooth muscle cells
B. Type I alveolar cells
,C. Type II alveolar cells
D. Pulmonary capillary endothelial cells
C. Type II alveolar cells
RATIONALE: Type II alveolar cells produce surfactant, which reduces
surface tension and increases lung compliance, preventing alveolar
collapse at end-expiration.
2. What does tidal volume (VT) represent?
A. The amount of air that moves into and out of the lungs during normal
breathing
B. The volume of blood perfusing the lungs each minute
C. The total air remaining after maximal expiration
D. The amount of air exchanged only during forced breathing
A. The amount of air that moves into and out of the lungs during normal
breathing
RATIONALE: Tidal volume is the amount of air moving into and out of
the lungs during normal breathing.
3. Which three processes are required for respiration according to the
Exam 2 study guide?
A. Filtration, secretion, and absorption
B. Compliance, recoil, and mucociliary clearance
C. Ventilation, perfusion, and diffusion
D. Inspiration, circulation, and metabolism
C. Ventilation, perfusion, and diffusion
RATIONALE: Respiration requires ventilation (movement of gases into
and out of the lungs), perfusion (movement of blood through the lungs),
and diffusion of gases between the lungs and blood.
4. What is a primary function of the conducting airways in addition to
moving air?
A. Producing pulmonary surfactant
B. Generating pulmonary capillary blood flow
,C. Warming, filtering, and humidifying inspired air
D. Performing the primary alveolar gas exchange
C. Warming, filtering, and humidifying inspired air
RATIONALE: Conducting airways act as a conduit for airflow but also
warm, filter, and humidify air as it moves through these structures.
5. Which virus is identified as the most common cause of the
common cold?
A. Parainfluenza virus
B. Respiratory syncytial virus
C. Influenza C virus
D. Rhinovirus
D. Rhinovirus
RATIONALE: Rhinovirus is specifically identified as the most common
cause of colds.
6. Which finding more strongly supports rhinosinusitis than an
uncomplicated common cold?
A. Postnasal drip without facial pain
B. Clear watery nasal secretions
C. Mild hoarseness
D. Fever with facial pain
D. Fever with facial pain
RATIONALE: Fever and facial pain are more commonly associated with
rhinosinusitis than with the common cold.
7. Which clinical pattern is most characteristic of influenza in the
study guide?
A. Gradual onset of isolated productive cough
B. Persistent facial pressure that worsens when bending forward
C. Abrupt fever, chills, myalgias, headache, and profound malaise
D. Chronic wheezing without systemic symptoms
, C. Abrupt fever, chills, myalgias, headache, and profound malaise
RATIONALE: Influenza is characterized by an abrupt onset of fever,
chills, myalgias, headache, and profound malaise.
8. During a prolonged asthma attack, what change contributes to
increasing work of breathing?
A. Decreased airway resistance
B. Air trapping and hyperinflation
C. Increased surfactant production
D. Bronchodilation
B. Air trapping and hyperinflation
RATIONALE: During a prolonged asthma attack, air trapping and
hyperinflation occur due to bronchoconstriction and mucus plugging,
increasing the work of breathing.
9. Which statement about cystic fibrosis is supported by the Exam 2
notes?
A. It is caused by a defective chloride channel leading to thick secretions
B. It primarily affects the cardiovascular system
C. It is an autoimmune disorder
D. It results in excessive surfactant production
A. It is caused by a defective chloride channel leading to thick
secretions
RATIONALE: Cystic fibrosis is caused by a mutation in the CFTR gene,
which encodes a chloride channel, leading to dehydrated, thick mucus in
the lungs and other organs.
10. Which neurologic change is most consistent with progressively
worsening hypoxemia?
A. Isolated loss of appetite without mental change
B. Restlessness progressing to confusion, delirium, stupor
C. Immediate loss of consciousness
D. Isolated peripheral neuropathy
