How should the nurse identify the rhythm shown in the diagram?
ventricular tachycardia
asystole
normal sinus rhythm
ventricular fibrillation
The Correct Answer is A
A. Ventricular tachycardia: Ventricular tachycardia (VT) is identified by a regular, fast rhythm with wide QRS complexes, typically without visible P waves. This rhythm often appears as consecutive, large, uniform waves, which is consistent with what is seen in the diagram.
B. Asystole: Asystole is characterized by a flat line, indicating no electrical activity, which is not present in this strip.
C. Normal sinus rhythm: Normal sinus rhythm would show identifiable P waves, a normal QRS complex, and a regular rate, which are not observed here.
D. Ventricular fibrillation: Ventricular fibrillation appears as chaotic, irregular waveforms with no clear QRS complexes or organization, which does not match the rhythm shown.
