Question

A nurse notes that the PR interval on a client's electrocardiograph (ECG) tracing is 0.14 second. What action does the nurse take?

a. Assess serum cardiac enzymes.
b. Administer 1 mg epinephrine IV.
c. Administer oxygen via nasal cannula.
d. Document the finding in the client's chart.

Answer 1

The nurse should document the finding in the client's chart.

Step-by-step explanation:

The nurse should d. Document the finding in the client's chart. The PR interval on an electrocardiogram (ECG) measures the time it takes for the electrical impulse to travel from the atria to the ventricles of the heart. A normal PR interval is between 0.12 to 0.20 second, so a PR interval of 0.14 second is within the normal range. Therefore, there is no need for immediate intervention. The nurse should simply document the finding in the client's chart.
