Question 1 of 5
A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?
Correct Answer: D
Rationale: The correct answer is D: The P wave falls before the QRS complex. In a normal sinus rhythm, the P wave should precede the QRS complex, indicating that the electrical impulse originates in the sinoatrial (S
A) node and travels through the atria before reaching the ventricles. This sequence signifies a coordinated electrical conduction through the heart, ensuring efficient and effective pumping.
Choices A, B, and C are incorrect as they describe abnormalities in the ECG readings that are not indicative of normal sinus rhythm.
Choice A suggests a prolonged PR interval, choice B indicates T wave inversion which can be a sign of cardiac ischemia or electrolyte imbalance, and choice C implies a widened QRS complex which may indicate conduction abnormalities.
Therefore, the correct interpretation of a normal sinus rhythm on ECG is when the P wave falls before the QRS complex.
