A client on the cardiac telemetry unit goes into Ventricular fibrillation and is unresponsive. Following initiation of the emergency call system (code blue), what is the next priority for the nurse in caring for the client?
A.
Administer amiodarone
B.
Prepare to defibrillation
C.
Prepare for Synchronized Cardioversion
D.
Administer epinephrine
The correct answer and Explanation is :
The correct answer is B. Prepare for Defibrillation.
Explanation:
When a patient on the cardiac telemetry unit goes into ventricular fibrillation (VF) and becomes unresponsive, the primary and immediate goal is to restore a normal heart rhythm. Ventricular fibrillation is a life-threatening arrhythmia where the ventricles are quivering ineffectively, failing to pump blood. This leads to a lack of effective circulation and requires rapid intervention.
- Defibrillation: This is the first and most crucial step in treating VF. Defibrillation involves delivering an electrical shock to the heart to reset the electrical activity and restore a normal rhythm. The sooner defibrillation is administered, the better the chances of survival and successful conversion to a normal rhythm. The American Heart Association (AHA) guidelines recommend defibrillation as the first action for VF, as it is the most effective treatment to terminate the arrhythmia and restore a viable rhythm.
- Administering Epinephrine (Option D): Epinephrine is used in the advanced cardiac life support (ACLS) protocol to improve perfusion during cardiopulmonary resuscitation (CPR) and to enhance the chances of successful defibrillation. However, it is administered after the initial defibrillation attempts if the rhythm does not convert, and it is not the immediate priority over defibrillation.
- Amiodarone (Option A): Amiodarone is an antiarrhythmic medication used to manage refractory VF or pulseless ventricular tachycardia (VT) after defibrillation attempts and epinephrine administration. Its role comes into play if VF persists despite initial defibrillation and CPR.
- Synchronized Cardioversion (Option C): Synchronized cardioversion is used for different arrhythmias such as atrial fibrillation or atrial flutter. It is not indicated for VF, as VF requires unsynchronized defibrillation.
In summary, the immediate priority in the event of ventricular fibrillation is to prepare for and administer defibrillation to restore a normal heart rhythm. Following this, other interventions such as epinephrine and amiodarone may be used based on the response to defibrillation and the ongoing condition of the patient.
