BIOD331
Pulmonary Disorders
Finals Exam (Qns & Ans)
2025
General Instructions
1. Read All Questions Carefully: Make sure you understand each question.
2. Time Management: You have a specific amount of time to complete the exam.
Keep an eye on the clock and pace yourself.
3. Allowed Materials: Only use materials that are explicitly allowed. Unauthorized
materials can lead to disqualification.
4. ANS Format: Follow the required format for your ANS. For example, multiple-
choice questions might need you to select the best ANS, while essay questions
require detailed responses.
5. Academic Integrity: Adhere to the university's honor code. Any form of cheating or
plagiarism is strictly prohibited.
6. Technical Requirements: Ensure your computer and internet connection are
stable. For online exams, you might need a webcam and microphone for proctoring
purposes.
7. Submission: Submit your ANS before the time expires. Late submissions might
not be accepted.

,1. Which of the following pathophysiological changes primarily
occurs in asthma?
- A) Airway remodeling
- B) Alveolar destruction
- C) Pulmonary vasculitis
- D) Eupneic hyperventilation
Correct ANS: A) Airway remodeling
Rationale: Asthma causes structural changes in the airways,
including hyperplasia of mucus glands and smooth muscle,
known as airway remodeling.
2. In patients with COPD, what is the primary mechanism of
airflow obstruction?
- A) Loss of elastin in alveolar walls
- B) Excessive mucus production
- C) Inflammation of the pleura
- D) Fibrosis of bronchioles
Correct ANS: A) Loss of elastin in alveolar walls
Rationale: In COPD, the destruction of elastin leads to loss of
lung recoil and obstructed airflow during expiration.

, 3. Which of the following is the hallmark sign of interstitial lung
disease?
- A) Productive cough
- B) Clubbing of fingers
- C) Wheezing
- D) Hemoptysis
Correct ANS: B) Clubbing of fingers
Rationale: Clubbing is commonly associated with chronic
hypoxia due to interstitial lung disease.
4. Which receptor is primarily involved in the detection of
carbon dioxide levels in the blood?
- A) Chemoreceptor
- B) Baroreceptor
- C) Proprioceptor
- D) Thermoreceptor
Correct ANS: A) Chemoreceptor
Rationale: Chemoreceptors in the central nervous system
respond to changes in carbon dioxide levels and help regulate
respiration.
