Question 1

What is the correct initial dose of adenosine for treating SVT in a child?

Accepted Answer

0.1 mg/kg IV (max 6 mg)

Answer

The initial adenosine dose for pediatric SVT is 0.1 mg/kg (maximum 6 mg) given as a rapid IV bolus immediately followed by a normal saline flush.

Question 2

Which of the following is a shockable cardiac arrest rhythm?

Accepted Answer

Ventricular fibrillation (VF)

Answer

Ventricular fibrillation (and pulseless VT) are shockable rhythms; asystole and PEA are non-shockable rhythms treated with CPR and epinephrine.

Question 3

A child has wide-complex tachycardia at 180 bpm with hypotension and altered mental status. What is the priority treatment?

Accepted Answer

Perform synchronized cardioversion

Answer

Hemodynamically unstable tachycardia requires immediate synchronized cardioversion regardless of QRS width, as waiting for drugs risks further deterioration.

Question 4

What is the recommended initial energy dose for synchronized cardioversion in a child with unstable SVT?

Accepted Answer

0.5-1 J/kg

Answer

The initial synchronized cardioversion dose for children is 0.5-1 J/kg, escalating to 2 J/kg if the first attempt is unsuccessful.

Question 5

What defines pulseless electrical activity (PEA)?

Accepted Answer

Organized electrical activity on ECG without a palpable pulse

Answer

PEA is defined as organized (or semi-organized) electrical activity visible on the ECG with no palpable pulse or effective cardiac output.
