The nurse is assessing an ECG strip of a 42-year-old client and finds a regular rate greater than 100, a normal QRS complex, a normal P wave in front of each QRS, a PR interval between 0.12 and 0.20 seconds, and a P: QRS ratio of 1:1. What is the nurse's interpretation of this rhythm?
Correct answer
B
Rationale
A regular rate >100 with normal P waves, QRS complexes, and PR interval indicates sinus tachycardia, a common response to stress, fever, or hypoxia.
