What is the recommended IV dose of amiodarone for stable wide-complex tachycardia (VT with pulse)?
Answer: 150 mg over 10 minutes
For stable wide-complex tachycardia, amiodarone is given as 150 mg IV over 10 minutes.
Sodium bicarbonate administration during cardiac arrest is most appropriate in which situation?
Answer: Hyperkalemia-induced cardiac arrest
Sodium bicarbonate is indicated in cardiac arrest caused by hyperkalemia or tricyclic antidepressant overdose.
What is the maximum dose of lidocaine that can be given as the initial bolus for pulseless VT/VF when amiodarone is unavailable?
Answer: 1–1.5 mg/kg
Lidocaine 1–1.5 mg/kg IV is given as the initial bolus when amiodarone is not available.
Which drug is preferred for rate control of atrial fibrillation with rapid ventricular response in a hemodynamically stable patient?
Answer: Diltiazem or metoprolol
Beta-blockers (e.g., metoprolol) or calcium channel blockers (e.g., diltiazem) are used for rate control in stable AF with RVR.
Which of the following is a correct route for drug delivery if IV access cannot be established during cardiac arrest?
Answer: Intraosseous (IO) access
Intraosseous (IO) access provides a rapid alternative route for drug delivery when IV access is unavailable during cardiac arrest.
