Extract:
A nurse is reviewing a client's cardiac rhythm strips and notes a constant P.R interval of 0.35 seconds.
Question 1 of 5
Which of the following dysrhythmias is the client displaying?
Correct Answer: A
Rationale: The correct answer is A: First-degree atrioventricular block. This dysrhythmia is characterized by a delay in conduction at the atrioventricular node, causing a prolonged PR interval (>0.20 sec) on ECG. It is a benign condition and does not typically require treatment unless symptomatic.
Choices B and D are more serious dysrhythmias that have different ECG patterns and clinical implications. Complete heart block (
Choice
B) presents with a lack of conduction between the atria and ventricles, leading to a slow ventricular rate. Atrial fibrillation (
Choice
D) is characterized by rapid, irregular atrial depolarizations without effective atrial contractions. Premature atrial complexes (
Choice
C) are early ectopic atrial beats that appear as abnormal P waves on ECG but do not cause significant conduction delays.
