Question

A drug that activates only β2 receptors could be given to a patient to relieve _____.

A. tetanus of skeletal muscle
B. tachycardia (excessively fast heart rate)
C. bradycardia (abnormally slow heart rate)
D. high blood glucose due to excessive breakdown of glycogen
E. breathing difficulty due to narrowing of bronchioles (airways of lungs)

Answer 1

A drug that activates only beta-2 receptors could be given to a patient to relieve breathing difficulty due to narrowing of bronchioles.

Step-by-step explanation:

A drug that activates only beta-2 receptors could be given to a patient to relieve breathing difficulty due to narrowing of bronchioles (airways of lungs). Beta-2 adrenergic receptors are responsible for causing smooth muscle relaxation in the bronchi, which helps to widen the airways and make breathing easier.
