Final answer:
The best shock sequence for a patient in ventricular tachycardia is to shock, perform CPR for 2 minutes, then reanalyze and shock again if needed.Option C is the correct answer.
Step-by-step explanation:
The appropriate shock sequence for a patient in ventricular tachycardia, where there is no pulse and the patient is not responsive, is best described by option C: Shock, 2 minutes of CPR, reanalyze, shock again if indicated. This sequence follows the current guidelines for Advanced Cardiovascular Life Support (ACLS).
After delivering an initial defibrillating shock, two minutes of CPR are provided to allow for potentially improved blood flow to the heart and brain.
The heart rhythm should then be reanalyzed to determine if an additional shock is required. The automated external defibrillator (AED) is instrumental in this process, as it gives instructions and determines if a shock is necessary based on the heart's electrical activity.
Following the ACLS guidelines, the shock sequence in ventricular tachycardia involves immediate defibrillation, followed by 2 minutes of CPR. This allows for circulation optimization. The AED plays a crucial role, providing instructions and analyzing rhythms to determine the need for subsequent shocks, ensuring a structured and efficient response.
