Correct Answer is D

Explanation

Choice A rationale: First-degree AV block is a type of heart block, not a dysrhythmia associated with palpitations, fatigue, and dizziness12.

Choice B rationale: Sinus bradycardia is a slow heart rate, not a rapid and irregular one12.

Choice C rationale: Sinus tachycardia is a fast heart rate but it is regular, not irregular12.

Choice D rationale: Atrial fibrillation is a fast and irregular heart rate, which aligns with the symptoms described34.

So, the correct answer is Choice D, after analysing all choices.

A. Administer amiodarone B. Prepare to defibrillation C. Prepare for Synchronized Cardioversion D. Administer epinephrine

Correct Answer is B

Explanation

Choice A rationale: While amiodarone is a medication used in the treatment of ventricular fibrillation, it is not the immediate priority in an unresponsive client34.

Choice B rationale: The immediate priority in a client who goes into ventricular fibrillation and is unresponsive is to prepare for defibrillation. This is a life-saving measure that can restore a normal heart rhythm34.

Choice C rationale: Synchronized cardioversion is not the immediate priority in a client who goes into ventricular fibrillation and is unresponsive34.

Choice D rationale: While epinephrine is a medication used in the treatment of ventricular fibrillation, it is not the immediate priority in an unresponsive client34.

So, the correct answer is B, after analysing all choices.
