Which of the following is a common side effect of beta-2 agonists such as albuterol?

Explanation:
Activation of beta-2 receptors with albuterol is mainly to dilate airways, but it also affects skeletal muscle, increasing neuromuscular excitability and causing fine tremors. This tremor is a common, dose-related side effect and is often more noticeable when therapy begins or with higher inhaled doses. It tends to improve over time or with techniques that limit systemic absorption, like using a spacer. The other options don’t fit this drug profile: drowsiness isn’t typical of beta-2 agonists, hypoglycemia isn’t expected (these agents can raise glucose levels), and hair loss isn’t associated with this medication.
