| Question | Answer |
|---|---|
| bacterial pneumonia | inflammation of the lung caused-->air spaces fill up with bacteria and neutrophils symptoms: SOB, cough, fever, chest pain usually infectious |
| Pneumocystis carinii | opportunistic infection that affects the immunosuppressed |
| aspiration pneumonia | caused by aspiration of pieces of vomit, food, or drink-->usually not sterile and contain bacteria result of vomiting while unconscious or in inviduals who don't have good control of swallowing (aging) |
| viral pneumonia | inflammation of the lung and causes interstitial tissue to fill with chronic inflammatory cells symptoms: cough, fever, headaches, muscle aches *Influenza virus pneumonia has tendency to become superinfected* with bacteria to produce bacterial pneum |
| superinfection | infection by a second organism that moved in after the first organism |
| tuberculosis | infectious bacteria that causes chronic inflammation can be removed by immune system or go into a dormant state and spread to lymph nodes and other areas of the body later PPD tests for exposure |
| Coccidiomycosis | infection caused by pathogenic fungus AKA valley fever-->causes focal growth and inflammation fungus lives in the ground and can be inhaled with dust symptoms: fever, cough, chest pain recovery possible without treatment but infection may spread |
| asthsma | episodic constriction of bronchioles can be induced by allergies or exercise submucosa becomes edematous and projects into lumen; mucus secreting glands become hyperactive and obstruct air flow-->cause wheezing treatment: bronchiole dilator, steroi |
| emphysema | condition where alveolar walls undergo destruction by proteases-->air spaces become fewer and very large causes: 1)smoking 2)alpha-1-antitrypsin deficiency (genetic disease) symptoms: dyspnea, barrel-chest |
| chronic bronchitis | Dx: 3 or more months of cough with sputum for at least 2 consecutive years smoking a major cause symptoms: cough, dyspnea-->both result of mucus secretion in large airways |
| lung cancer | 1) primary cancer of the lung (usually carcinomas)-->most common form of cancer in this country 2) metastatic cancer to the lung (carcinomas or sarcomas) destroys lung tissue; produces cancer cachexia; bad prognosis |
