A nurse is reviewing a client's cardiac rhythm strips and notes a constant P-R interval of
0.35 seconds. Which of the following dysrhythmias is the client displaying?

Premature atrial complexes

Complete heart block

Atrial fibrillation

First-degree atrioventricular block

Answer and Explanation

The Correct Answer is D

A.   Incorrect. Premature atrial complexes do not typically affect the P-R interval. They are characterized by an early P-wave followed by a QRS complex.
B.   Incorrect. Complete heart block is characterized by a dissociation between the P-waves and QRS complexes, resulting in no relationship between atrial and ventricular activity.
C.   Incorrect. Atrial fibrillation is characterized by chaotic and irregular atrial activity without distinct P-waves, making the P-R interval irrelevant.
D.   Correct. In first-degree atrioventricular block, the P-R interval is prolonged beyond the normal range of 0.12-0.20 seconds. A constant P-R interval of 0.35 seconds indicates a first- degree atrioventricular block.
