Common side effects of beta-adrenergic agonists include which of the following?

• A. Tremor and palpitations
• B. Nausea and dizziness
• C. Bradycardia
• D. Hyperglycemia

Answer: (C)

Beta-adrenergic agonists mimic the sympathetic nervous system, increasing heart rate and boosting adrenergic activity in skeletal muscle. The most common side effects reflect this stimulation: tremor from beta-2 effects in muscles and palpitations from the heart’s increased rate. While nausea, dizziness, or metabolic effects like hyperglycemia can occur, they’re not as characteristic as the combination of tremor and palpitations. Bradycardia would go against the drug’s tendency to elevate heart rate, so it isn’t a typical frequent side effect.
