Pneumonia: Types, Causative Organisms & Management
A free NEET-PG General Medicine sample that converts pneumonia from a list of organisms into clinical pattern recognition: lobar consolidation, atypical pneumonia, auscultatory signs, chest X-ray clues, organism-specific traps, work-up, and treatment logic.
Why This Free Sample Matters
Pneumonia questions often look easy until the stem adds an immunocompromised patient, an atypical electrolyte abnormality, or a confusing chest X-ray pattern. This note teaches you to let the clinical and radiological pattern decide the organism.
The core exam habit is simple: focal consolidation with dullness, bronchial breathing and a lobar infiltrate points toward typical bacterial pneumonia, while diffuse bilateral ground-glass disease with dry cough and hypoxia pushes you toward Pneumocystis or viral causes.
What You’ll Learn
- Pneumococcus versus Pneumocystis — why HIV status should not override a classic focal lobar consolidation pattern.
- Chest X-ray localisation — lobar consolidation, silhouette sign, right middle/lower lobe clues, round pneumonia, ground-glass opacities, effusion, abscess and pneumatocele.
- Auscultation logic — bronchial breathing, increased tactile vocal fremitus, whispering pectoriloquy/bronchophony and egophony.
- Organism-pattern matching — pneumococcus, Klebsiella, Mycoplasma, Legionella, Chlamydia psittaci, Francisella, Coxiella, Staphylococcus aureus, Pseudomonas, anaerobes, Pneumocystis and viral causes.
- Legionella profile — pneumonia with confusion, significant hyponatraemia, negative Gram stain and the need for macrolide or respiratory fluoroquinolone therapy.
- Work-up strategy — CBC, blood culture, CRP/procalcitonin, BUN/electrolytes, chest X-ray, sputum Gram stain/culture, sputum adequacy, urine antigen and PCR where appropriate.
- Management framework — outpatient, ward and ICU treatment logic, plus MRSA/Pseudomonas add-ons and organism-specific treatment rules.
- NEET-PG clinical MCQ reasoning — how to answer organism-identification questions from the clinical pattern rather than from one isolated risk factor.
