A patient uses a metered-dose inhaler with a prescribed bronchodilator. Which instruction improves delivery to the lungs?
Correct answer: B. Exhale fully, then inhale slowly while pressing
- A. Breathe in quickly after pressing the canister
- B. Exhale fully, then inhale slowly while pressing
- C. Swallow the medication after spraying it
- D. Spray twice rapidly without breathing between doses
Explanation
The patient should exhale, begin a slow deep inhalation, and press the canister during inhalation so the aerosol reaches the lower airways. Rapid inhalation, swallowing, or repeated sprays without proper breaths reduces effective delivery.
