Gram_ bacteria develop in host with underlying, chronic, debilitating conditions, severe acute illness, and recent antibiotic therapy. Gram_ infections result in early tissue __ and abscess formation.
Intra-alveolar \+ Pneumococcal \+ - - Necrosis
Klebsiella, Haemophilus influenzaes, pseudomonas aeruginosa,proteus, serratia
Examples of what?
Common infecting organisms for gram- bacteria
- Shaking chills
- Fever
- Chest pain if pleuritic involvement
- Cough becoming PRODUCTIVE of PURULENT, BLOOD-STREAKED or RUSTY sputum
- Decreased or bronchial breath sounds and/or CRACKLES
- Tachypnea
- INCREASED WBC count
- Hypoxemia, HYPOcapnea initially; hypercapnea with increasing severity
- CXR: confirmation of infiltrate
Bacterial pneumonia
Pertinent physical findings
An interstitial or intra-alveolar inflammatory process caused by viral agents (influenza, adenovirus, cytomegalovirus, herpes, parainfluenza, respiratory synctial virus, measles)
Viral pneumonia
- Recent hx of upper respiratory infection
- Fever
- Chills
- DRY cough
- Headaches
- Decreased breath sounds and/or CRACKLES
- Hypoxemia and HYPERcapnea
- NORMAL WBC count
- CXR: confirmation of interstitial infiltrate
Viral pneumonia
Pertinent physical findings
Aspirated material causes acute inflammatory rxn within lungs
Aspiration PNA
Aspiration PNA usually found in patients with ____, fixed neck ____, ____, impaired ____, NM disease, recent ____
Dysphagia, extension, intoxication, consciousness, neuromuscular disease, recent anesthesia
- Symptoms begin shortly after causal event (hours)
- Cough maybe DRY at onset, progresses to PRODUCTIVE PUTRID secretions
- Dyspnea
- Tachypnea
- Cyanosis
- Tachycardia
- WHEEZES and CRACKLES with decreased breath sounds
- HYPOxemia, HYPERcapnea in severe cases
- Chest pain over involved area
- Fever
- WBC shows varying degrees of LEUKOCYTOSIS
- CXR: initially shows pneumonitis, chronic event shows necrotizing PNA with cavitation
Aspiration PNA
Mycobacterium tuberculosis: Infection spread by acrosolized droplets from untreated infected host.

TB: increased incidence of TB in patients with ____
HIV
TB: Pertinent physical findings of primary disease can go unnoticed, as it only causes mild symptoms including: (3)
- Slight nonproductive cough
