Final answer:
The statement indicates that the client understands the importance of rinsing the mouth right after using the inhaler to prevent oral thrush.
Step-by-step explanation:
The student's question suggests that the client understands the importance of rinsing the mouth after using an inhaler. This practice is recommended because it helps to prevent the development of oral thrush, a fungal infection that can occur when medication from the inhaler is left behind in the mouth and throat. Corticosteroid inhalers, in particular, can contribute to this risk when the medicine remains on the mucous membranes. Therefore, the correct answer is that the client understands the importance of rinsing the mouth after using the inhaler. It is not necessary to wait for an hour before rinsing; rinsing should be done immediately after inhaler use to reduce the risk of oral thrush.
