1.

Two rounds of adenosine can be administered to attempt to convert a tachyarrhythmia to sinus rhythm. What is the recommended dosing of adenosine in such a scenario?

6 mg IVP followed by 6 mg IVP if no conversion
12 mg IVP followed by 6 mg IVP if no conversion
12 mg IVP followed by 12 mg IVP if no conversion
6 mg IVP followed by 12 mg IVP if no conversion
2.

Unstable patients with regular narrow-complex supraventricular tachycardia can be given what medication as synchronized cardioversion is being prepared?

Adenosine 6 mg IVP
Amiodarone 150 mg IVP
Atropine 0.5 mg IVP
Epinephrine 1 mg IVP
3.

Which of the following antiarrhythmic medications should be considered alongside vagal maneuvers for regular narrow-complex tachyarrhythmias?*

Amiodarone
Epinephrine
Adenosine
Atropine
4.

 If a patient experiencing a tachyarrhythmia becomes unstable, what is the most important intervention to consider?

Antiarrhythmic medications
Synchronized cardioversion
IV fluids
Seek expert consultation
5.

Which of the following scenarios calls for synchronized cardioversion?
