The nurse is documenting a client’s assessment. The rhythm below was obtained from the client’s cardiac monitor. How should the nurse document this strip?

Atrial tachycardia

Ventricular fibrillation

Atrial flutter

Sinus bradycardia

Answer and Explanation

The Correct Answer is C

A. Atrial tachycardia: Atrial tachycardia is a rapid heart rhythm originating from the atria, but it does not have the characteristic "sawtooth" pattern seen in atrial flutter.

B. Ventricular fibrillation: Ventricular fibrillation is a chaotic rhythm originating from the ventricles, characterized by irregular, rapid waves with no discernible P waves or QRS complexes.

C. Atrial flutter: Atrial flutter is recognized by a "sawtooth" pattern of P waves, indicating rapid atrial depolarizations.

D. Sinus bradycardia: Sinus bradycardia is a slow but regular rhythm originating from the sinus node, with normal P waves and QRS complexes.

Correct Answer is A

Explanation

A. First-degree heart block: A prolonged PR interval greater than 0.20 seconds, as seen in this case, indicates first-degree heart block, which is a delay in conduction at the AV node.

B. Second-degree heart block. Second-degree heart block is characterized by some PR intervals being prolonged with occasional dropped beats (non-conducted P waves).

C. Bundle branch block. Bundle branch block causes a wide QRS complex (greater than 0.12 seconds), which is not seen here.

D. Sinus arrhythmia. Sinus arrhythmia involves changes in heart rate due to respiratory cycles, not prolonged PR intervals.

A. Pharmacological toxins B. Pleural infusion C. Autoimmune disorders D. Viral infections E. Peripheral vascular disease

Correct Answer is ["A","C","D"]

Explanation

A. Pharmacological toxins can contribute to myocarditis, as certain drugs may induce inflammatory responses in the myocardium.

B. Pleural infusion is incorrect. Pleural infusion, or pleural effusion, is not directly associated with myocarditis.

C. Autoimmune disorders such as lupus and rheumatoid arthritis can predispose individuals to myocarditis due to immune system dysregulation.

D. Viral infections are a major cause of myocarditis, particularly infections like coxsackievirus, parvovirus B19, and HIV.

E. Peripheral vascular disease is incorrect. While peripheral vascular disease is related to poor circulation, it does not directly contribute to the development of myocarditis.
