.
Answer 1 is incorrect because atropine is used for bradycardia or first-degree atrioventricular (AV) blocks. Answer 2 is correct because epinephrine (adrenalin) is a first-line drug used during CPR to stimulate cardiac activity. Answer 3 is incorrect because Lasix is a diuretic, not an antiarrhythmic. Answer 4 is incorrect because lidocaine is indicated for ventricular arrhythmias, specifically premature ventricular contractions (PVCs).
