Question 1

Adenosine is used in pediatric emergencies to treat which rhythm?

Accepted Answer

Supraventricular tachycardia (SVT)

Answer

Adenosine transiently blocks AV conduction to terminate reentry SVT and is the first-line drug for stable SVT in children.

Question 2

What technique must be used when giving adenosine via peripheral IV to ensure it reaches circulation?

Accepted Answer

Rapid IV push followed by a large saline flush

Answer

Adenosine has an extremely short half-life (<10 seconds), so it must be given as a rapid bolus immediately followed by a large saline flush to reach central circulation.

Question 3

What is the recommended initial dose of adenosine for pediatric SVT?

Accepted Answer

0.1 mg/kg rapid IV/IO push (max 6 mg)

Answer

The initial adenosine dose is 0.1 mg/kg (maximum 6 mg) given as a rapid IV or IO push with a flush.

Question 4

Amiodarone is indicated in pediatric cardiac arrest for which refractory condition?

Accepted Answer

Ventricular fibrillation or pulseless ventricular tachycardia unresponsive to defibrillation

Answer

Amiodarone is used for shock-refractory VF or pulseless VT, given at 5 mg/kg IV/IO bolus during resuscitation.

Question 5

Which fluid is recommended as the first-line resuscitation fluid for hypovolemic shock in a pediatric patient?

Accepted Answer

Isotonic crystalloid (0.9% normal saline or lactated Ringer's)

Answer

Isotonic crystalloids such as normal saline or lactated Ringer's are the first-line fluids for pediatric hypovolemic shock resuscitation.
