A 12-year-old boy was recently diagnosed with asthma, and his primary care provider hasprescribed a corticosteroid to be administered by metered-dose inhaler. This drug achieves a therapeutic effect by which of the following means?

A)By increasing the number of beta-adrenergic receptors
B)By increasing the muscle tone in the smooth muscle of the trachea
C)By increasing the permeability of the alveolar membrane

A. By increasing the number of beta-adrenergic receptors

Explanation:

Based on the scenario being described within the question it can be said that this drug achieves a therapeutic effect by increasing the number of beta-adrenergic receptors . This drug increases the amount of beta-adrenergic receptors while at the same time increasing or restoring beta receptor response to beta-adrenergic bronchodilating drugs.
