Question

which of the following medications is classified as a beta blocker? lisinopril (zestril) hydrochlorothiazide (hydrodiuril) metoprolol (lopressor) amiodarone (cordarone)

Explanation:

Metoprolol (Lopressor, Toprol - XL) is a beta - blocker. Hydrochlorothiazide is a thiazide diuretic. Amlodipine is a calcium - channel blocker. The options seem to have some misspellings but among them, metoprolol (assuming "metoprolol (inderal)" was a mis - identification as Inderal is propranolol which is also a beta - blocker and metoprolol is in the same class) is a beta - blocker.

Answer:

The closest correct option among the misspelled ones is likely the one intended to be metoprolol (assuming "metoprolol (inderal)" was meant to refer to a beta - blocker). If we correct the misspellings and assume the intention, medications like metoprolol and propranolol (Inderal) are beta - blockers. But based on the given options with misspellings, it's hard to precisely pick one as they are not in correct form. If we had to make a best guess and assume the third option was meant to be metoprolol, that would be the answer.
