C: "I'll hold the mouthpiece 3 inches in front of my mouth before depressing the canister."
D: "I'll hold my breath for up to 5 seconds after inhaling the medication."

Answer 1

The correct answer is option D, which states the patient should hold their breath for up to 5 seconds after inhaling the medication to ensure it reaches the lungs effectively.

Step-by-step explanation:

The correct statement that indicates an understanding of using a metered-dose inhaler for asthma is: "I'll hold my breath for up to 5 seconds after inhaling the medication." When using an inhaler, it is important to inhale the medication deeply to ensure it reaches the alveoli, the mucus-lined sacs in the lungs where gas exchange occurs. After inhaling, holding one's breath allows the medication more time to settle in the lungs and take effect. This practice also aligns with the natural process our bodies use to take deep breaths, allowing surface tension to help fully expand the alveoli. Therefore, option D is the correct answer.
