16 / 50
16. The process of taking air into the lungs is called â
Inspiration involves contraction of diaphragm and intercostal muscles to draw air in.
17 / 50
17. The exchange of gases in the lungs occurs by â
Diffusion allows oxygen and carbon dioxide to move across alveolar membranes.
18 / 50
18. The primary site for gas exchange in the lungs is â
Alveoli are thin-walled air sacs where oxygen and carbon dioxide are exchanged between air and blood.
19 / 50
19. Which of the following conditions causes airway hyperresponsiveness?
Asthma involves hypersensitive airways that constrict in response to irritants.
20 / 50
20. What is the main cause of hypoxemia?
Hypoxemia occurs due to impaired oxygen exchange in the lungs, seen in respiratory failure and COPD.
21 / 50
21. What does COPD stand for?
COPD means chronic obstructive pulmonary disease, causing airflow blockage.
22 / 50
22. Which condition is characterized by chronic airway inflammation and reversible obstruction?
Asthma involves airway inflammation, bronchospasm, and mucus production, leading to wheezing and breathlessness.
23 / 50
23. Which of the following is not part of the lower respiratory tract?
The pharynx is part of the upper respiratory system.
24 / 50
24. Which microorganism most commonly causes bacterial pneumonia?
Streptococcus pneumoniae is the leading cause of community-acquired bacterial pneumonia.
25 / 50
25. Which part of the brain controls the rate of respiration?
The medulla oblongata and pons regulate the rhythm and depth of breathing.
26 / 50
26. Which of the following is a symptom of respiratory acidosis?
COâ retention leads to confusion, headache, and shallow breathing in respiratory acidosis.
27 / 50
27. Which of the following is a long-term complication of chronic bronchitis?
Chronic bronchitis can lead to cor pulmonale, right heart failure from lung disease.
28 / 50
28. Clubbing of fingers is seen in â
Chronic hypoxia in lung diseases like COPD or bronchiectasis causes finger clubbing.
29 / 50
29. Which respiratory condition is caused by Mycobacterium tuberculosis?
Tuberculosis (TB) affects lung tissue due to bacterial infection by M. tuberculosis.
30 / 50
30. Which of the following indicates difficulty in breathing?
Dyspnea refers to shortness or difficulty in breathing.
31 / 50
31. In which condition are both lungs filled with fluid and inflammation seen diffusely?
ARDS causes widespread inflammation and fluid leakage into alveoli.
32 / 50
32. Which gas is most important for stimulating breathing?
High carbon dioxide levels trigger the brain to increase breathing rate.
33 / 50
33. Which of the following may cause respiratory alkalosis?
Hyperventilation reduces COâ levels, leading to respiratory alkalosis.
34 / 50
34. What is the function of the epiglottis?
The epiglottis prevents food from entering the trachea during swallowing.
35 / 50
35. Which gas stimulates the respiratory center in the brain?
Carbon dioxide increases acidity of blood, stimulating the medulla oblongata to increase respiration.
36 / 50
36. Which of the following is a common symptom of pulmonary embolism?
Sudden shortness of breath and chest pain are classic symptoms of pulmonary embolism.
37 / 50
37. Which instrument measures lung capacity?
A spirometer measures lung volume and capacity to assess pulmonary function.
