Final answer:

Medication acting on the β2-adrenergic receptor will likely be used to prevent airway constriction during extubation in an asthmatic patient.

Step-by-step explanation:

The anesthesia provider will likely use a medication that stimulates the β2-adrenergic receptor to prevent severe airway constriction and spasm during extubation of a severe asthmatic patient. Activation of the β2 receptor leads to smooth muscle relaxation, specifically in the bronchi, which opens the airways and makes breathing easier. Medications that target these receptors are commonly used in the treatment of asthma.
