A nurse is reviewing the ECG of a patient who has been complaining of episodic dizziness. The ECG tracing shows periods of rapid heart rate with a narrow QRS complex followed by a sudden return to a normal heart rate. Based on the nurse's understanding of the cardiac cycle and ECG interpretation, which of the following actions should the nurse prioritize?
1
Monitor the patient for further episodes while continuing routine care.
2
Immediately administer prescribed anti-arrhythmic medication.
3
Document the findings and inform the attending physician for possible paroxysmal supraventricular tachycardia (PSVT).
4
Advise the patient to increase fluid and salt intake to manage symptoms.
