What is the recommended administration time for the pediatric calcium chloride dose (20 mg/kg)?

• A. Over two minutes
• B. Over five minutes
• C. Over ten minutes
• D. Over thirty seconds

Answer: (B)

Calcium chloride must be given slowly to avoid causing dangerous, rapid shifts in the heart and veins. For the pediatric dose of 20 mg/kg, infusing it over about five minutes allows the calcium to enter the circulation gradually, reducing the risk of bradycardia, hypotension, and vein irritation or extravasation injury. This is why a slower infusion time, specifically over five minutes, is recommended.
