How should the nurse interpret the rhythm shown on the electrocardiogram strip shown in the diagram?

C:\Users\USER\AppData\Local\Microsoft\Windows\INetCache\Content.MSO\4EE007BD.tmp

A.

asystole

B.

ventricular fibrillation

C.

sinus tachycardia

D.

sinus bradycardia

Answer and Explanation

The Correct Answer is B

A. Asystole: Asystole would show a flat line with no electrical activity, which is not seen here.

 

B. Ventricular fibrillation: Ventricular fibrillation is characterized by chaotic, irregular waveforms without distinct P waves, QRS complexes, or T waves. The ECG strip shows this disorganized, erratic electrical activity consistent with ventricular fibrillation.

 

C. Sinus tachycardia: Sinus tachycardia would display a regular rhythm with identifiable P waves, QRS complexes, and T waves at a faster rate. This is not present in the ECG strip.

 

D. Sinus bradycardia: Sinus bradycardia would show a slower rate but with an organized rhythm and distinct P, QRS, and T waves. This is not indicated in the strip.

Correct Answer is ["A","B","C","E"]

Explanation

A. Erythema (redness) can occur at the site of a gout attack due to inflammation in the affected joint.

B. Hyperuricemia (elevated levels of uric acid in the blood) is a hallmark of gout, leading to the formation of urate crystals.

C. Pain is a prominent symptom of gout, particularly during an acute attack when joints become inflamed and tender.

D. Diarrhea is not a direct complication of gout; it is more associated with gastrointestinal issues or medications.

E. Edema (swelling) can occur in the affected joint due to inflammation associated with gout.

Correct Answer is A

Explanation

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.
