Path 370 Week 4 Quiz
1. What is a sign of viral pneumonia?: Dry cough (Productive in bacterial pneumonia)
2. What are risk factors of pulmonary TB?: Immunosuppression, Overcrowded, Poverty
3. Signs/Symptoms of bacterial pneumonia?: Productive cough and parenchymal infiltrates on
x-ray
4. What is the organism that causes TB?: Mycobacterium tuberculosis
5. Findings in TB?: Ghon tubercles on x-ray (TB bacteria ingested by macrophages and walled off by granulo-
mas)
6. What antibody is associated with inhaled allergens in asthma?: IgE
7. Symptoms associated with allergic (extrinsic) asthma?: Inflammation, mucosal edema,
and bronchoconstriction
8. What is lacking in emphysema that leads to alveolar destruction?: Lack of al-
pha-1-antitrypsin

, 9. What causes hypersecretion of mucus in chronic bronchitis?: Recurrent infection
10. What is a common characteristic shared by all obstructive pulmonary disor-
ders?: Resistance to airflow
11. What is extrinsic asthma?: Asthma that is caused by substances outside the body, such as pollen, dust,
food additives.
12. What is intrinsic asthma?: Asthma triggered by infections, stress, or environmental factors. Non
allergen specific.
13. How does COPD lead to barrel chest?: Causes air to be trapped in the lungs forcing the rib cage
to expand
14. How does emphysema (type a COPD) destroy alveolar walls?: Unchecked release of
proteolytic enzymes by immune cells
15. What heart condition does chronic bronchitis (type b COPD) lead to?: cor
pulmonale (enlarged right ventricle due to increased pulmonary vascular resistance)
