Question 1 of 5
The nurse notes that the client's rhythm strip indicates a PR-interval of 0.28 seconds. What is the nurse's analysis of this problem?
Correct Answer: D
Rationale: In 1st degree AV block, the PR interval is consistently prolonged, usually more than 0.20 seconds, but it is a constant, non-variable delay in the conduction between the atria and ventricles. A PR interval of 0.28 seconds is characteristic of a first-degree AV block.
