Based on this rhythm strip, which interpretation should the nurse make?

A. Junctional tachycardia: Junctional tachycardia originates from the AV node, typically with a narrow QRS, absent or inverted P waves, and a rate of 100–180 bpm. The strip does not show these features. B. Second-degree Type II AV block (3:1).Type II AV block (Mobitz II) shows dropped QRS complexes with constant PR intervals before conducted beats. This strip does not show missing QRS complexes in a 3:1 pattern. C. Ventricular fibrillation. VF is characterized by a chaotic, disorganized rhythm with no discernible P waves, QRS complexes, or T waves, completely different from this organized flutter pattern. D. Atrial flutter is characterized by regular, rapid atrial depolarizations (flutter waves) at a rate of 250–350 bpm. These waves create a "sawtooth" pattern on the ECG.The ventricular response may be regular or irregular, depending on AV conduction. This is different from atrial fibrillation (which has irregularly irregular R-R intervals and no discrete P waves).
