A child with tachycardia and altered mental status shows a narrow complex on the ECG. After establishing vascular access, what is the MOST appropriate initial medication and dosage?
A child with tachycardia and altered mental status shows a narrow complex on the ECG. After establishing vascular access, what is the MOST appropriate initial medication and dosage?
- Administer adenosine 0.2 mg/kg rapid IV/IO push, not to exceed 12 mg. (correct)
- Perform synchronized cardioversion starting at 2 J/kg.
- Administer adenosine 0.1 mg/kg rapid IV/IO push, not to exceed 6 mg.
- Administer amiodarone 5 mg/kg IV/IO push.
A child presents with tachycardia, a narrow QRS complex, and altered mental status failing to respond to initial doses of adenosine. There is no rhythm change. What intervention should be prioritized?
A child presents with tachycardia, a narrow QRS complex, and altered mental status failing to respond to initial doses of adenosine. There is no rhythm change. What intervention should be prioritized?
- Administer amiodarone 5 mg/kg IV/IO over 20-60 minutes.
- Perform vagal maneuvers, such as carotid massage.
- Administer a second dose of adenosine at 0.3 mg/kg.
- Initiate synchronized cardioversion starting at 0.5 to 1 J/kg. (correct)
During synchronized cardioversion on a child with tachycardia, the first attempt at 0.5 J/kg is unsuccessful. What is the next appropriate step?
During synchronized cardioversion on a child with tachycardia, the first attempt at 0.5 J/kg is unsuccessful. What is the next appropriate step?
- Administer lidocaine 1 mg/kg IV/IO.
- Increase the energy to 2 J/kg for the next attempt. (correct)
- Immediately administer epinephrine 0.01 mg/kg IV/IO.
- Switch to unsynchronized defibrillation at 4 J/kg.

No:
- Synchronized Cardioversion: start at 0.5 to 1 J/kg; may use 2 J/kg if unsuccessful
- Consider sedation ETOMIDATE 0.15 mg/kg IV/IO
