Question

What is the most appropriate intervention for a rapidly deteriorating patient who has this lead II ECG?

a) Synchronized cardioversion
b) Initiate immediate defibrillation
c) Administer intravenous antibiotics
d) Perform a non-contrast head CT scan

Answer 1

For a patient with a deteriorating condition as shown on an ECG, indicative of ventricular fibrillation, the correct intervention is to initiate immediate defibrillation. This procedure provides a shock to the heart to re-establish an effective rhythm and is critical to prevent brain death.

Step-by-step explanation:

In a scenario where a patient's ECG indicates a rapidly deteriorating condition such as ventricular fibrillation, the most appropriate intervention would be to initiate immediate defibrillation. Defibrillation is the process of delivering a therapeutic dose of electrical energy to the heart with an automated external defibrillator (AED) or defibrillator. This electrical shock halts the chaotic rhythm and allows the heart to re-establish an effective rhythm.

When cardiac arrest occurs during a condition like ventricular fibrillation, applying a defibrillation shock is crucial. Without prompt intervention, this type of arrhythmia can lead to brain death in a matter of minutes. Synchronized cardioversion is reserved for stable patients, antibiotics are for infections, and a non-contrast head CT scan is for assessing neurological issues, not appropriate in this cardiac emergency.
