03a: Pneumonia Flashcards
Including lobar pneumonia, what are other forms that pneumonic process can take?
- Interstitial
- Necrotizing (small cavities under 2 cm)
- Lung abscesses (cavities over 2 cm)
List the three key clinical features seen in patient with classic pneumonia.
- Fever
- Cough (with/without sputum)
- Dyspnea
May have pleuritic chest pain
List the physical exam signs you would find in classic pneumonia (lobar consolidation).
- Dullness to percussion
- Increased fremitus
- Crackles and bronchial breath sounds
Which clinical features would make you suspect atypical pneumonia as opposed to classical pneumonia?
Dry cough and prominence of extra-pulmonary symptoms (HA, myalgia, N/V, diarrhea)
(X)% of healthy adults aspirate pathogens that cause pnuemonia in their sleep. Aspiration occurs more frequently in which patients?
X = 50
Pts with impaired consciousness, neuromuscular disorders, or oropharynx/swallowing disorders
Pneumonia patients in “outpatient group 1” are under age (X), have no history of (Y) disease or risk factors for (Z) infection.
X = 60 Y = Cardiopulmonary Z = gram-neg
24 y.o. med student with no past med history presents with pneumonia symptoms. Which pathogens most likely on your differential?
Outpatient Group 1:
- S. pneumo
- Mycoplasma pneumo
- Chlamydia pneumo
- Viral (Rhinovirus, Influenza, Parainfluenza)
Pneumonia: Outpatient group 1 first-line agents/drugs.
Macrolides or doxycycline
T/F: Pneumonia patients responding to antibiotics will show radiologic resolution before clinical improvement.
False - clinical improvement 2-4 days but radiologic resolution takes 4-6 weeks
50 y.o. patient with COPD presenting with pneumonia symptoms. Which pathogens most likely on your differential?
Outpatient Group 2:
- S. pneumo
- H. flu
- Viral
Pneumonia: Outpatient group 2 first-line agents/drugs.
- Resp fluoroquinolone
OR - Beta-lactam with Macrolide
T/F: Bacteremia occurs in 20-30% of S. pneumo CAP.
True
List the criteria used to decide if pneumonia patient should be admitted to hospital.
CURB-65
C: Confusion
U: Uremia (BUN over 20)
R: RR over 30/min
B: Low Blood P
Age 65 or older
T/F: All nursing home residents presenting with pneumonia symptoms should be admitted to hospital, regardless of age.
True
T/F: Health-Care Associated Pneumonia is in hospitalized patients or in patients with extensive health-care contact (such as nursing home).
Partly true, but NOT in hospitalized patients
Ventilator associated pneumonia occurs (X) hours after (Y) procedure.
X = 48-72 Y = intubation
List the criteria that, if even one is present, patient should be admitted to ICU.
- Septic shock
2. Resp failure requiring ventilation/intubation
T/F: Microbiologic diagnosis/ID for pneumonia is only established in about 50% of cases.
True - treatment recommendations often empiric (based on likely pathogens)
T/F: Parapneumonic effusion and empyema are common in pneumococcal pneumonia.
False - effusion common, but empyema rare (2%)
Hemorrhagic bullous myringitis, infection of (X), present in 5% of pneumonia patients with (Y) as pathogen.
X = tympanic membrane (and nearby ear canal) Y = mycoplasma pneumo
Neutrophil (immune) impairment: which infectious pathogens (general) are you most worried about?
Extracellular bacteria and fungi
