Final answer:
Carvedilol would be the safest beta blocker to use in a patient with asthma due to its alpha-blocking activity. Labetalol is also a potential safe option.
Step-by-step explanation:
Carvedilol would be the safest beta blocker to use in a patient with asthma. Unlike other beta blockers like Propranolol and Atenolol, Carvedilol has some alpha-blocking activity as well, which may help to alleviate bronchoconstriction caused by beta blockade. Labetalol, another beta blocker with alpha-blocking activity, could also be a safe option in this scenario.
