Sample item

What is a common adverse effect of beta blockers in susceptible patients?

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

The answer and the reasoning

B. Bronchospasm

Nonselective beta blockade can block beta-2 mediated bronchodilation, provoking bronchospasm in patients with reactive airway disease.

Option by option

  • A. Urinary frequency

    Urinary frequency is not the classic beta-blocker adverse effect.

  • B. Bronchospasm (correct)

    Correct: beta-2 blockade can precipitate bronchospasm.

  • C. Excess salivation

    Excess salivation reflects muscarinic stimulation.

  • D. Profound miosis

    Miosis is primarily a parasympathetic effect.
