Final answer:
The ECG findings indicate that the correct interpretation of the rhythm is Sinus Tachycardia, characterized by a heart rate greater than 100 beats/minute but with regular atrial and ventricular rhythms and normal PR interval and QRS complex durations.
Step-by-step explanation:
The client's electrocardiogram (ECG) strip shows an atrial and ventricular rate of 110 beats/minute, a PR interval of 0.14 second, a QRS complex measuring 0.08 second, and regular PP and RR intervals.
Based on these findings, the nurse should correctly interpret this rhythm as Sinus Tachycardia.
Sinus tachycardia is characterized by a heart rate that is faster than normal (greater than 100 beats/min in adults) but with a regular rhythm.
The PR interval and QRS duration are within normal limits, indicating that the atria are depolarizing normally and the impulse is passing through the ventricles in a typical fashion.
By definition, sinus rhythm indicates that the electrical activity is originating from the sinoatrial (SA) node, which is the normal pacemaker of the heart. A normal sinus rhythm would have a rate of 60 to 100 beats per minute, so a rate of 110 beats per minute is too fast, ruling out normal sinus rhythm, but not profoundly so, which is why it's categorized as tachycardia and not another form of arrhythmia.
This rhythm is also not sinus dysrhythmia, which would show an irregular rate, nor is it sinus bradycardia, which would have a rate less than 60 beats per minute.
