Answer to Question 1

A
Feedback:
A metered-dose inhaler is a canister that contains medication under pressure; the aerosolized drug is released when the container is compressed. A metered-dose inhaler is not propeller-driven. An aerosol results after a liquid drug is forced through a narrow channel using pressurized air or an inert gas.

Answer to Question 2

B
A nurse should obtain subjective data about the client's pain, including the client's own description of the pain; its location (where pain occurs); onset and duration (when pain began, how long it has existed, and any pain patterns); quality (what the pain feels like); intensity (how severe the pain is); aggravating and alleviating factors (things that increase or decrease the pain); factors accompanying the pain (impact on daily activities such as sleep and nutrition); and the meaning of pain to the client.
