, Pathophysiology Exam 2026/2027: 130 Q&A
Instructions: Select the best answer for each multiple-choice question. Each question has
one correct answer unless otherwise specified.
Section A: Respiratory & Acid-Base Disorders
1. Which two pulmonary conditions are recognized causes of respiratory acidosis?
A. Asthma and shortness of breath
B. Hyperventilation and fever
C. Cystic fibrosis and hypoventilation
D. Anemia and pain
Answer: C
Explanation: Respiratory acidosis results from alveolar hypoventilation, leading to CO2
retention. Cystic fibrosis causes chronic airway obstruction, while hypoventilation directly
reduces CO2 excretion. The other options involve hyperventilation or conditions not
primarily causing hypoventilation.
2. What is the primary function of diffusion in the context of physiological gas exchange?
A. It is the process by which molecules move from high-concentration areas to low-
concentration areas.
B. It is the process by which solvent molecules pass through a semipermeable membrane
from a less concentrated solution into a more concentrated one.
C. It is a process by which certain molecules pass through the plasma membrane with the
help of carrier proteins.
D. It is a process by which a substance requires energy to pass through a membrane against a
concentration gradient.
Answer: A
Explanation: Diffusion is a passive process where molecules move down their concentration
gradient without energy expenditure. Options B, C, and D describe osmosis, facilitated
diffusion, and active transport, respectively.
,3. A patient's assessment reveals dyspnea and audible wheezing. These findings are most
characteristic of which chronic respiratory condition?
A. Bradycardia with decreased urine output
B. Weak, thready pulse and warm, dry skin
C. Dyspnea and audible wheezing
D. Unlabored respirations and leg edema
Answer: C
Explanation: Dyspnea (shortness of breath) and wheezing are hallmark signs of chronic
obstructive pulmonary disease (COPD) due to airway inflammation and obstruction.
4. A sandblaster presents with dyspnea, cough with sputum, tachypnea, and pulmonary
hypertension. A chest X-ray reveals small nodular lesions. Which occupational lung disease
is most consistent with this presentation?
A. Silicosis
B. Bronchiectasis
C. Asbestosis
D. Pulmonary tuberculosis
Answer: A
Explanation: Silicosis is caused by inhaling crystalline silica dust, common in sandblasting,
mining, and stone cutting. The nodular lesions on X-ray are a classic finding.
Section B: Neurological & Neuromuscular Disorders
5. A child diagnosed with Neurobehavioral Disorder Associated with Prenatal Alcohol
Exposure (ND-PAE) would most likely exhibit which core deficit?
A. Nearsightedness
B. Trouble planning
C. Frequent nausea
D. Helpfulness
Answer: B
Explanation: ND-PAE is characterized by significant impairments in executive function,
, including planning, organization, and impulse control, directly related to prenatal alcohol
exposure.
6. A patient presents with progressive muscle weakness, atrophy, and fasciculations
(twitching) in the lower extremities. An electromyography is ordered. Which diagnosis is
most likely?
A. Multiple sclerosis
B. Parkinson's disease
C. Amyotrophic lateral sclerosis
D. Restless legs syndrome
Answer: C
Explanation: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative
disease affecting both upper and lower motor neurons, leading to the described symptoms of
weakness, atrophy, and twitching. An antiglutamate drug (e.g., riluzole) is a standard
treatment.
7. What is one of the two primary classifications of Amyotrophic Lateral Sclerosis (ALS)?
A. Nonproliferative
B. Acute
C. Sporadic
D. Exuciatic
Answer: C
Explanation: ALS is classified as either sporadic (no clear family history, most common
form) or familial (inherited).
8. Which clinical sign is characteristically associated with amyotrophic lateral sclerosis
(ALS)?
A. Impaired mental flexibility
B. Blurred vision
C. Head drop
D. Slowed thought processing
