How should the nurse interpret the rhythm shown on the electrocardiogram strip shown in the diagram?

A. Asystole: Asystole would show a flat line with no electrical activity, which is not seen here. B. Ventricular fibrillation: Ventricular fibrillation is characterized by chaotic, irregular waveforms without distinct P waves, QRS complexes, or T waves. The ECG strip shows this disorganized, erratic electrical activity consistent with ventricular fibrillation. C. Sinus tachycardia: Sinus tachycardia would display a regular rhythm with identifiable P waves, QRS complexes, and T waves at a faster rate. This is not present in the ECG strip. D. Sinus bradycardia: Sinus bradycardia would show a slower rate but with an organized rhythm and distinct P, QRS, and T waves. This is not indicated in the strip.
