What is the Calcium Chloride dose for adult stable really wide complex tachycardia?

• A. 0.5 g
• B. 1 g
• C. 1.5 g
• D. 2 g

Answer: (B)

Calcium chloride is used to rapidly stabilize the heart when hyperkalemia or calcium-channel blocker overdose is suspected, which can present as a wide-complex tachycardia. In adults, the standard starting dose is a 1-gram IV push (10% CaCl2 solution). This amount quickly raises extracellular calcium, helping the myocardium regain stability and counteract the effects of high potassium or calcium-channel blockade. A smaller dose like 0.5 g would be less reliably effective, while larger doses such as 1.5 g or 2 g increase the risk of hypercalcemia and other complications and are not the typical starting dose. Administer with continuous ECG monitoring and flush afterward. In the absence of suspicion for hyperkalemia or CCB overdose, management of stable wide-complex tachycardia usually centers on antiarrhythmics rather than calcium.
