A nurse is analyzing a client's electrocardiogram (ECG) strip and identifies the following information: Heart rate: 92/min Rhythm: Irregular P wave:
Unable to identify PR interval:
Unable to measure QRS duration:
0.10 seconds Based upon this information,
thenurse should interpret the client's rhythm as indicating which of the following?
Supraventricular tachycardia
Atrial fibrillation
Sinus bradycardia
First-degree heart block
The Correct Answer is B
A. Supraventricular tachycardia (SVT) typically has identifiable P waves; the absence of P waves suggests a different condition.
B. Atrial fibrillation is characterized by an irregular rhythm, inability to identify P waves, and varying intervals. This interpretation aligns with the client's ECG findings.
C. Sinus bradycardia would show identifiable P waves and a regular rhythm with a heart rate less than 60 bpm, which does not match the provided information.
D. First-degree heart block would also show identifiable P waves and regularity in the rhythm with a prolonged PR interval, which is not indicated here.

Explanation
A. Weak pulses are more indicative of reduced cardiac output or other cardiac issues, rather than specifically a large patent ductus arteriosus (PDA).
B. Cyanosis with crying can occur in various conditions, but it is not a hallmark of a large PDA; it typically presents with other symptoms.
C. Chronic hypoxemia is more associated with severe heart defects or lung conditions, whereas a large PDA may present with other signs first.
D. A systolic murmur is a classic finding in large PDAs due to the left-to-right shunting of blood, making it the most expected manifestation in this scenario.
