  1. If the sputum collected from a patient with pneumonia is absent of organisms after a gram stain, then this suggests a pneumonia caused by what pathogens? (think: L.a.M.M.P)
    • Legionella pneumophila
    • a virus
    • Mycoplasma pneumoniae
    • Mycobacterium tuberculosis
    • PCP
  2. _____ (3 words) with a  _____ (2 words) is a helpful clinical pattern when trying to diagnose pneumonia.
    foul smelling sputum with a rusty color
  3. What are some useful "special" stains to use when sampling the sputum of a pneumonia patient?
    • acid-fast bacteria (for TB)
    • Giemsa, GMS or Toluidine blue (for PCP)
  4. True or false. A bronchoscopy is not a very effective diagnostic tool for pneumonia.
    True (may introduce oral flora into the bronchi or lungs)
  5. What are the 2 benefits of taking a blood sample to diagnose a pneumonia patient?
    • proves etiology
    • provides susceptibility of organism
  6. True or false. A chest X-ray can be used as a diagnostic tool in terms of the etiology of infection in a pneumonia patient.
    False, a chest X-ray cannot be used as a diagnostic tool in terms of the etiology of infection in a pneumonia patient.
  7. What are the 2 most "classic" clinical symptoms seen in patients with community-acquired pneumonia (CAP)?
    • productive cough
    • fever
  8. True or false. Neutropenia is a poor prognostic sign if seen in a community-acquired pneumonia (CAP) patient.
    true
  9. What organism is the most common cause for community-acquired pneumonia in the elderly or in someone who has been infected with influenza recently?

    A. Haemophilus influenzae
    B. Mycoplasma pneumoniae
    C. Moraxella catarrhalis
    D. Staphylococcus aureus
    D. Staphylococcus aureus
    (this multiple choice question has been scrambled)
  10. If a patient is suffering from aspiration pneumonia, is it necessary to perform a sputum culture?
    No, because the sputum may be contaminated with mixed anaerobes and epithelial cells of the oral cavity and give a false positive.
  11. True or false. Gram negative organisms, like K. pneumoniae, E. coli, and P. mirabilis, are not typically seen as causative agents in community-acquired pneumonia.
    true
  12. What are the 6 most common viruses that cause community-acquired pneumonia? (think: I.V. C.R.A.P.)
    • Influenza
    • Varicella-zoster
    • CMV
    • RSV
    • Adenovirus
    • Parainfluenza-3
  13. How is "atypical pneumonia" best identified?
    absence of organisms on gram stain
  14. What are the 2 main pathogens involved in "atypical pneumonia"?
    • Mycoplasma pneumoniae
    • Chlamydia pneumoniae
  15. What are the risk factors for aspiration pneumonia?
    • having a disease state with altered consciousness
    • abnormal gag reflex and swallowing
    • may lead to lung abscess
    • antianaerobic treatment
  16. What are the 2 most important factors involved in the acquisition of nosocomial pneumonia?
    • prior antibiotic use
    • lack of hand washing
  17. What 3 vaccines can help to prevent pneumonia? (think: H.I.P.)
    • Haemophilus influenzae B
    • Influenza
    • Pneumovax
