PHM Exam--Ch. 13 Questions With Complete Solutions
Aspergillus can cause... Correct Answers COPD (d/t
inflammation & secretions)
***most people who get COPD from this have some other
issues, ex. smokers, asthmatic, immunocompromised
***fungal respiratory infection
Bird flu is which type of influenza? What strain? Correct
Answers influenza A, H5N1
Compare the mortality rates of SARS-CoV-1 & MERS Correct
Answers MERS has a much higher mortality rate (30-40%
mortality), SARS (9.5%), MERS mostly affected people with
underlying conditions (mostly older men, could be d/t cultural
factors such as women going out less)
Describe mortality vs morbidity of influenza Correct Answers
mortality not very high, but morbidity (how many ppl sick) high
***ppl who die are very old, very young, or
immunocompromised more likely to die d/t a secondary
infection of pneumonia ex. strep pneumonia or staph aureus
Describe the incidence of legionella pneumophila Correct
Answers incidences have increased over the years, still
uncommon though
Describe the process of culturing legionella pneumophila
Correct Answers fastidious organism, can be grown on media
but difficult bc lives inside protozoan (specifically amoeba)
, Does SARS-CoV-2 target the same receptor as SARS-CoV-1?
Correct Answers no, different receptors
***this explains why there are cardiac Sx associated with
SARS-CoV-2 & not SARS-CoV-1
DTP vs DTaP vs Tdap Correct Answers DTP had whole cell
pertussis, but d/t concerns about seizures and autism, DTaP was
created with acellular pertussis (only contains components of
pertussis rather than whole cell)
**both contain diptheria and tetanus toxins
***Tdap mostly boosts for tetanus toxin, but you also get the
diphtheria toxin and acellular pertussis components
Histoplasma capsulatum can lead to... What is the mortality rate
of this? Correct Answers pneumonia which has a 30%
mortality rate
How can legionella pneumophila infections be prevented?
Correct Answers keep water storage above 140 F & use
monochloramine rather than free chlorine
How common is TB? Correct Answers >30% of world
population has TB (this include latent infections, but can
become active)
How does atypical pneumonia caused by legionella
pneumophila present differently from typical pneumonia?
Correct Answers very different Sx, takes longer to develop Sx
& has GI components
