Sample item

What is a common effect of beta-2 agonist overdose?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Tremor and hypokalaemia

Beta-2 agonists can drive potassium into cells and stimulate skeletal-muscle receptors, causing tremor, palpitations, and hypokalaemia.

Option by option

  • A. Severe constipation from ileus

    Ileus is not typical beta-2 toxicity.

  • B. Urinary retention only

    Urinary retention is anticholinergic.

  • C. Miosis and bradycardia

    Miosis and bradycardia are parasympathetic patterns.

  • D. Tremor and hypokalaemia (correct)

    Correct: beta-2 activation causes tremor and intracellular potassium shift.
