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.

B. While some vision changes are expected with aging, the specific difficulties the client is experiencing suggest a more definitive condition rather than "normal" vision changes.
C. While cataracts can cause vision issues, the specific symptoms described (trouble reading and seeing objects up close) are more characteristic of presbyopia.
D. Glaucoma typically involves peripheral vision loss rather than difficulty with near vision, so this option is not supported by the findings.
