What is the difference between typical and atypical Pneumonia? - Answer- Typical:
bacteria in the alveoli
-lobar: affects an entire love of the lung
-bronchopneumonia: patchy distribution over more than one lobe
Atypical: viral and mycoplasma infections of the alveolar septum or interstitium
What causes Typical PN? - Answer- Typical pneumonia can result from infection by
bacteria that multiply extracellularly in the alveoli and cause inflammation and exudation
of fluid into air-filled aveloar spaces.t
What is atypical PN caused by? - Answer- Viral and mycoplasma infections

previously healed primary lesion
-immediate cell-mediated response walls off infection in airways
Extrapulmonary TB - Answer- During secondary TB, bacilli disseminate to regional
lymph nodes, kidneys, long bones, genital tract, brain, and meninges
These complications are grave
What is the Ghon focus? - Answer- Granulomatous lesion containing macrophages, T
cells, inactive TB bacteria
-body's immune system corners and quarantines the TB INFECTION

What are the risk factors? - Answer- YES
How does cigarette smoking lead to cancer? - Answer- Toxins in the cigarettes alter the
lung cell DNA
Smoke from smoking contains carcinogenic chemicals that trigger genetic changes
converting normal bronchial cells to cancer cells.

a. Primary
b. Latent
c. Miliary
d. Secondary - Answer- D. Secondary
Respiratory Distress Syndrome (RDS)
What causes it? How is it treated? - Answer- Lack of surfactant, infants not strong
enough to inflate their alveoli
- mechanical ventilation, artificial surfactant
True or False: Premature infants are at greater risk of developing respiratory distress
syndrome than term infants - Answer- TRUE
What is Croup?
What organism causes it?
What happens in Croup? - Answer- Affects 1-2 year olds

and expiratory strider, more severe at night

obstruction of small airways
All of the following are true EXCEPT:
a. Sinusitis is the inflammation of the paranasal sinuses

d. Nasal polyps can obstruct the sinus openings and facilitate sinus infections - Answer-
c. Being flight attendants can lead to increase sinus ventilation and this can cause
sinusitis
A client's chest x-ray and pathology report identify a granulomatous lesion that contains

d. Macrophages - Answer- a. Ghon focus
Define Keratitis - Answer- Refers to inflammation of the cornea, which can result in
partial or total loss of vision caused by infectious or noninfectious sources
Define Cataract - Answer- Lens opacity that interferes with the transmission of light to
the retina
- effects of aging, genetic influences, environmental and metabolic influences, drugs,
and injury
Which of the following is known to affect pupillary reflex?
A. Opiate usage
B. Damage to CN II
C. Infection of the uveal tract
D. Increase in intraocular pressure - Answer- A. Opiate usage
What are opportunistic pathogens? - Answer- Only affects you when your immune
system is trash, e.g those with HIV/AIDs (Usually die of secondary infection)
What are prions? - Answer- No genome, proteins
