How should the nurse identify the rhythm shown in the diagram?

C:\Users\USER\AppData\Local\Microsoft\Windows\INetCache\Content.MSO\411E6DD3.tmp

A.

ventricular tachycardia

B.

asystole

C.

normal sinus rhythm

D.

ventricular fibrillation

Answer and Explanation

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.
