Medical Surgical EKG #6

Question

A client in the ICU received advanced cardiac life support after his monitor revealed the following rhythm, which the nurse identified as:

Answers

  1. Supraventricular tachycardia
    • Rationale:

      This answer is not correct because supraventricular tachycardia has discernable QRS complexes. Ventricular fibrillation is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles.

  2. Complete heart block
    • Rationale:

      This answer is not correct because in a complete heart block, the atrial rhythm is different from the ventricular rhythm. Ventricular fibrillation is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles.

  3. Ventricular fibrillation
    • Rationale:

      This answer is correct because ventricular fibrillation is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles. CPR must be initiated immediately. The question indicates that CPR is in progress and rhythm is identified as ventricular fibrillation. The priority is to administer a shock immediately.

  4. Ventricular tachycardia
    • Rationale:

      This answer is not correct because in ventricular tachycardia, three or more premature ventricular contractions occur in a row with a heart rate that exceeds 100 bpm. The ventricular and atrial rhythms are usually regular however the P wave may be difficult to detect. Ventricular fibrillation is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles.

Overview

Ventricular fibrillation is a rapid, disorganized ventricular rhythm that causes ineffective quivering of the ventricles.

Explanation

Learning Outcomes

Ventricular fibrillation is a rapid disorganized ventricular rhythm that causes ineffective quivering of the ventricles. clients may become unresponsive, without a pulse, and may stop breathing. CPR must be initiated immediately. The question indicates that CPR is in progress and rhythm is identified as ventricular fibrillation. The priority is to administer a shock immediately.

Test Taking Tip

Ventricular fibrillation and pulseless ventricular tachycardia are life threatening dysrhythmias. Immediate action (immediate CPR and defibrillation) is required to keep this client alive.
