Respiratory Flashcards
Bronchoconstriction in asthma is mediated by a type I hypersensitivity reaction.
True
Primary tuberculosis consists if granulomatous inflammation with a central caseating
zone surrounded by histiocytes.
True
Paradoxical embolism occurs when venous emboli impact in the pulmonary arteries
True
Bronchopneumonia affects anatomically delineated segments or the entirety of a lobe or
lung
False. That is lobar pneumonia
Risk factors for vascular obstruction in the lungs include immobilization, malignancy, and
cardiac failure.
True
Type II respiratory failure results in a compensatory metabolic alkalosis
True
Adenocarcinomas develop from areas of dysplastic alveolar epithelium.
True
Paraseptal emphysema involves the airspaces distal to the terminal bronchioles.
False. Panlobular emphysema
Paraseptal emphysema involves the airspaces distal to the terminal bronchioles.
False. Panlobular emphysema
Respiratory failure occurs as a result of impaired ventilation, impaired perfusion or
impaired gas exchange.
True
The inflammatory reaction in rhinitis is mediated via type I ad III hypersensitivity
reactions
True
Asbestos exposure results in asbestosis and primary malignant mesothelioma
True
Aspiration of a tooth during an extraction procedure may result in bronchial obstruction
and subsequent lung abscess.
True
The respiratory bronchiole is proximal to the terminal respiratory unit and is lined by
ciliated epithelium
True
There is no correlation between occupational hazards and the development of lung
tumors.
False
Squamous cell carcinoma of the lung arises from the normal respiratory lining the
respiratory passages
True
Asthma, emphysema, and chronic bronchitis are examples of chronic obstructive airway
diseases
True
Type II pneumocytes display surface microvilli and are responsible for surfactant
secretion
True
Primary pulmonary tuberculosis usually manifests as cavitations of the apical aspect
of the lung.
False
Primary pulmonary tuberculosis usually manifests as cavitations of the apical aspect
of the lung.
False
