What is the maximum cumulative adenosine dose across the first two doses in pediatric stable SVT?

• A. 18 mg
• B. 12 mg
• C. 24 mg
• D. 30 mg

Answer: (A)

Dosing adenosine in pediatric stable SVT uses weight-based amounts with per-dose caps. The first dose is 0.1 mg/kg, limited to a maximum of 6 mg. If there’s no resolution, the second dose is 0.2 mg/kg, with a maximum of 12 mg. Adding these two per-dose caps gives a maximum cumulative amount of 6 mg + 12 mg = 18 mg across the first two doses. In practice, the exact dose depends on the child’s weight, but the ceiling for the first two doses is 18 mg. (A third dose may be used if needed, but that’s beyond the first two.)
