A nurse is providing teaching to a client who has a new prescription for albuterol. Which of the following instructions should the nurse include?

The correct answer is C: Use this medication 30 min before exercise. Albuterol is a bronchodilator that helps open up the airways, making it easier to breathe. Using it before exercise can help prevent exercise-induced bronchospasm. Taking it once daily at bedtime (A) is incorrect as albuterol is usually used as needed for quick relief. Rinsing the mouth after using the inhaler (B) is important to prevent oral thrush from steroid inhalers, not albuterol. Avoiding shaking the inhaler before use (D) is incorrect, as shaking the inhaler helps mix the medication for proper delivery.
