A. Adenosine 6 mg IV push B. Immediate cardioversion C. Adenosine 12 mg IV push D. Amiodarone 150 mg bolus followed by a 24 hour drip

Correct Answer is B

Explanation

A. Adenosine 6 mg IV push: Adenosine is used for certain supraventricular tachycardias, but immediate cardioversion is the first priority for a client with atrial flutter and chest pain.

B. Immediate cardioversion: This is the correct answer. Immediate cardioversion is indicated for atrial flutter with signs of hemodynamic instability, such as chest pain and shortness of breath.

C. Adenosine 12 mg IV push: Adenosine may be used after the first dose of 6 mg if the initial dose was ineffective, but cardioversion takes precedence for unstable patients.

D. Amiodarone 150 mg bolus followed by a 24-hour drip: Amiodarone is an antiarrhythmic used for rate control or rhythm conversion but is not the first step for hemodynamically unstable clients with atrial flutter.
