How should the nurse interpret the rhythm depicted in the image?

A. This would show a regular rhythm with a consistent rate (60-100 bpm) and clear P waves before each QRS complex, which is not present in asystole. B. This indicates a slow heart rate (below 60 bpm) but would still display P waves and QRS complexes; asystole shows no electrical activity. C. This is the correct interpretation as it represents a flatline on the ECG, indicating no electrical activity in the heart. D. This would show a rapid heart rate (above 100 bpm) with present P waves, which is not the case in asystole.
