Final answer:
The statement indicating an understanding of the nurse's teaching on how to use a fluticasone inhaler correctly is the one suggesting to rinse the mouth after use to prevent side effects such as oral thrush.
Step-by-step explanation:
Reflecting an understanding of the nurse's teaching on self-administration of a fluticasone inhaler, the correct statement would be: "I will rinse my mouth with water after using the inhaler." This step is crucial to prevent possible side effects such as oral thrush (a yeast infection in the mouth) that can occur with the use of inhaled corticosteroids.
Cleaning the spacer with disinfectant wipes does not adhere to the standard cleaning instructions for such devices. It's recommended to use soapy water and let it air dry. Waiting 15 minutes between puffs is incorrect; the typical guidance is to wait about 30 seconds to 1 minute unless otherwise directed by a healthcare provider. Finally, regarding the use of multiple inhalers, the fluticasone inhaler may not necessarily be used before the others; it depends on the type of medication and the specific instructions provided by the doctor or respiratory therapist.
