PNA Flashcards
PNA can be caused by what?
- Bacteria
- Virus
- Fungi
Which organism is responsible for approximately 36% of all CAP pneumonia in adults?
S. Pneumoniae
What type of disease does S. pneumonia cause.
pneumococcal disease
First line choice of treatment for CAP
- Amoxicillin
Why has Macrolide therapy no longer first line therapy for CAP?
Resistance to streptococcus pneumonia resistance
Which organism is responsible or most frequently seen after an influenza virus infection?
Pneumococcal pna
Aside from S. pneumoniae what other organisms cause CAP?
- Haemophilus
- S. Aureus
- Legionella
- Mycoplasma
What organism is associated with walking PNA?
- Mycoplasma
Is it a common occurrence to have bacterial and viral PNA?
it is common
to have viral and bacterial coinfection in CAP
What are contributing factors to the development of PNA?
- Smoking
- Altered level of conscious
- compromised immune system
- underlying chronic conditions
Almirall and colleagues found the strongest correlations for CAP risk?
a previous
history of CAP, current tobacco use, environmental irritant exposures, poor oral health or nutritional status,
functional impairment, comorbid chronic obstructive
pulmonary disease or asthma, immunosuppressive
therapy, oral steroid use, and the use of gastric-acid
suppressive drugs such as proton pump inhibitors
and H2 antagonists
A nasal or bleating quality of transmitted vocal sounds that is elicited
when the patient says the letter “E”
and to the examiner, it sounds like
the letter “A”
Egophony
e incubation period for pneumococcal
pneumonia is
1 to 3 days
Transmission of M.
pneumoniae results
from person-to-person transfer
of respiratory droplets, and the incubation period
is between 1 and 4 weeks
organism responsible for atypical
M. pneumoniae
the percentage of the people that contract M. pneumoniae that go on to develop pna is
10%
Why is atypical PNA termed walking PNA
pneumoniae starts as
a systemic illness with symptoms such as fever, sore
throat, headache, and cough.21 Symptoms tend to
gradually worsen over a period of weeks and then
self-resolve
Clinicians can
increase the accuracy of chest radiography by
ensuring
that both posteroanterior and laterolateral images are
obtained.
If a patient suspicious for PNA has a negative chest x ray what should be done
repeat chest x ray in 24 hours
