The physical method used to measure aerosol particle size distribution using
multiple steps is:
Cascade Impaction
An aerosol is best defined as
a suspension of a solid or liquid particles in a gas

whole question)

1-10 micrograms
You are the RT working in the ED. A 67 year old male with chronic bronchitis
presents with stress and vital signs has a heart rate of 123 beats/min and a
RR at 28 breaths/min. Upon auscultation you hear mild to moderate expiratory
wheezing. Which of the following is the least appropriate to administer an
aerosolized drug to this patient?
DPI (because they can not produce an adequate inspiratory flow o 30-90mL)
What Process of inspiratory holds in conjunction with delivery will:
allows for better deposition.

says it stays fresher. What should you tell you patient on how to store it.
Needs to be stored at room temperature
You are teaching the proper us of MDI to an elderly patient who has difficulty
with coordinating breath actuation with inspiratory effort. What suggestion or
device would help this patient overcome this?
Spacer/Champer, or SVN
Greatest limitation with a DPI?
