What is the recommended adult dose of Calcium Chloride in this protocol?

• A. 0.5 g IV push
• B. 1 g slow IVP/IO
• C. 2 g slow IVP/IO
• D. 10 mEq IV

Answer: (B)

Calcium chloride is given to rapidly supply calcium ions when needed, but it must be delivered in a controlled way to avoid harming the patient. The recommended adult dose is one gram, given slowly through an IV or IO line. Administering it slowly helps prevent sharp changes in heart rhythm and vein irritation, allowing the calcium to reach the circulation safely. In most EMS protocols, this preparation is a 10% solution, so one gram corresponds to about 10 mL and is infused over a short period rather than dumped in quickly. This dosing aligns with how the drug is intended to be used in emergencies like hyperkalemia or calcium channel blocker toxicity, where timely but cautious administration is important. The other dosing options either underrepresent, overreach, or use a different unit that isn’t used for this protocol’s calcium chloride dosing.
