Questions and Answers

What is the primary characteristic of lobar pneumonia?

  • It primarily affects individuals with strong immune systems.
  • It involves patchy consolidation of lung tissue.
  • It typically involves an entire lobe of a lung. (correct)
  • It affects only the bronchi and bronchioles.

How does bronchopneumonia typically manifest in the lungs?

  • By the presence of numerous discrete inflammatory lesions.
  • As a uniform consolidation of the entire lung.
  • In dependent portions of lung tissue with patchy consolidation. (correct)
  • Through the formation of protein-rich hyaline membranes.

What primarily characterizes interstitial pneumonia?

  • It occurs exclusively in immunocompromised individuals.
  • It has significant exudate accumulation in the alveoli.
  • It primarily affects the alveolar walls and connective tissue. (correct)
  • It leads to extensive edema throughout the lungs.

Flashcards

Lobar Pneumonia

Affects an entire lung lobe, marked by fluid buildup and lung consolidation due to immune response.

Bronchopneumonia

Involves patchy lung consolidation, mostly in bronchioles, with less fluid in the air sacs.

Interstitial Pneumonia

Inflammation primarily targets lung tissue's walls, not the air sacs initially, causing gas exchange issues.

Miliary Pneumonia

Bloodstream-spread infection resulting in many inflammation spots, mostly seen in impaired immune systems.

Lung Consolidation

Solidification of lung tissue due to fluid buildup; hinders oxygen exchange.

Bacterial Pneumonia

Bacterial pneumonia, usually upper-airway bacteria enter alveoli, triggering immune response, creating fluid-filled consolidation.
