viruses
who is most susceptible for pneumonia?
those with history of pneumonia
what is the most common cause of pneumonia in a child?
virus
what is the most common cause of pneumonia in an adult?
bacterial
T/F
Pneumonia is the leading infectious killer of children under 12
FALSE
it is the leading infectious killer of children under the age of 5
What is a non pathogenic cause of pneumonia?
aspiration pneumonia
what may cause a patient to obtain hospital acquired pneumonia?
a ventilator with improper oral care and suctioning
who is at highest risk for aspiration pneumonia?
Patients with an OG, Ventilated, poor gag reflex, or stroke pts
what is 3 ways to prevent pneumonia?
immunization
adequate nutrition
environmental factors
what does pneumonia create a mismatch in?
ventilation and perfusion
what does the ventilation and perfusion mismatch cause?
arterial hypoxia
how can pneumonia cause death?
it effects ventilation and perfusion; oxygen has trouble reaching the blood; causing the body to not work properly
the risk of infection increases and can easily spread throughout the body

It is very important to take a cough suppressant when you have pneumonia
FALSE
if you suppress the cough, there is no way for all of the sputum to escape the lungs
