A nurse is reinforcing discharge teaching with a client following an episode of status asthmaticus. The client has a prescription for two inhalations from an albuterol metered-dose inhaler. Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale Albuterol is a rapid-acting beta-2 agonist that works to dilate the bronchioles during acute bronchospasm. Standard protocols require waiting approximately 1 minute between puffs of the same medication to allow the first dose to begin opening the airways, which facilitates deeper penetration of the second dose. Waiting 10 minutes is clinically unnecessary and delays the therapeutic effect of the rescue medication, potentially worsening respiratory distress. Choice B rationale Proper inhaler technique involves tilting the head slightly back, not forward, to create a more direct and open path for the aerosolized medication to travel through the oropharynx and into the lower respiratory tract. Tilting the head forward constricts the airway and increases the likelihood that the medication will impact the back of the throat or the tongue instead of reaching the bronchioles. Choice C rationale The choice of hand used to hold the metered-dose inhaler does not impact the pharmacological efficacy of the medication. Clients should use whichever hand provides the most stability and coordination to effectively coordinate the actuation of the canister with their inhalation. Instructing a client to use their non-dominant hand is an arbitrary requirement that could lead to poor coordination and inadequate dosing. Choice D rationale Holding the breath for at least 10 seconds, or as long as comfortable, allows the medication particles to settle onto the surface of the bronchial mucosa via sedimentation. This pauses the airflow and ensures that the albuterol molecules remain in the lungs long enough to bind to beta-2 adrenergic receptors. Failure to hold the breath results in the immediate exhalation of the medication, reducing the bronchodilatory effect.
