The nurse is caring for a patient whose cardiac monitor shows a total absence of electrical impulse as indicated by a flat line. The nurse does not detect a pulse or blood pressure. The nurse would document this as which of the following rhythms?

Atrial fibrillation

Asystole

Ventricular fibrillation

Atrial flutter

Answer and Explanation

The Correct Answer is B

A.   Atrial fibrillation is characterized by rapid, irregular electrical impulses originating from the atria, resulting in a quivering or fibrillating motion of the atria rather than a coordinated contraction.
B.   Asystole is the absence of any electrical activity on the cardiac monitor, resulting in a flat line. It indicates the absence of ventricular contraction and is considered a medical emergency requiring immediate intervention (CPR and advanced cardiac life support).
C.   Ventricular fibrillation is characterized by chaotic, disorganized electrical activity in the ventricles, resulting in ineffective quivering of the ventricles and loss of cardiac output.
D.   Atrial flutter is characterized by rapid but regular electrical impulses originating from the atria, resulting in a sawtooth pattern on the ECG tracing.
