Correct answer: B — Query the prescription because propranolol may precipitate bronchospasm

Non-selective beta-blockers such as propranolol can precipitate bronchospasm and reduce the effect of beta2 agonists. This is particularly relevant in a patient using salbutamol regularly. The prescription should be queried and a safer option considered.
