Answer:
"I need to shake the inhaler well before taking the medication."
Explanation:
One of the main recommendations for using an inhaler is to shake it before use. So this sentence is the one that indicates that <u>the client has understood the indications given by the nurse.</u>
As for the other options, it is advisable to wait 1 minute before another inhalation, <u>not 30 minutes.</u>
And taking <u>a deep breath before inhalingit is also not correct</u>, because it is advisable to exhale (empty the lungs) before using the inhaler so that the medication fills the lungs
