MULTIPLE CHOICE

1. Allergic (extrinsic) asthma is associated with

ANS:  C

Extrinsic (allergic) asthma is mediated by IgE triggers. Allergic (extrinsic) asthma involves hyperresponsiveness of the airways. Antigens are the precipitating factors. Airway obstruction is reversible.

REF:   Pg. 476

2. Copious amounts of foul-smelling sputum are generally associated with

ANS:  D

Copious, foul-smelling respiratory secretions are associated with bronchiectasis. Copious, foul-smelling respiratory secretions are not associated with emphysema, epiglottitis, or pulmonary edema.

REF:   Pgs. 489-490

3. Emphysema results from destruction of alveolar walls and capillaries, which is due to

ANS:  A

The pathologic changes leading to alveolar destruction are associated with the release of proteolytic enzymes from inflammatory cells such as neutrophils and macrophages. While air trapping occurs in emphysema, the destruction of alveolar walls and capillaries is due to release of proteolytic enzymes. Lack of a₁-antitrypsin can result in emphysema. Autoantibodies are not involved in destruction of alveolar walls and capillaries in emphysema.

REF:   Pg. 487

4. Chronic bronchitis often leads to cor pulmonale because of

ANS:  B

Chronic bronchitis often leads to cor pulmonale due to increased pulmonary vascular resistance when right ventricular end-diastolic pressure increases. Ventricular hypoxia, left ventricular strain, and hypervolemia do not lead to cor pulmonale.
