CCT Cardiac Monitoring & Emergency Response 2

Question 1

A patient's telemetry monitor shows a rhythm with no discernible P waves, an irregular RR interval, and a ventricular rate of 110 bpm. What is the most likely interpretation?

Accepted Answer

Atrial fibrillation with rapid ventricular response

Answer

Absent P waves with an irregularly irregular ventricular rhythm are the hallmark findings of atrial fibrillation.

Question 2

During continuous ECG monitoring, you observe a pause of 3.2 seconds with no P waves or QRS complexes. Which intervention is most immediately appropriate?

Accepted Answer

Assess the patient and check lead connections

Answer

Before escalating treatment, the technician must first assess the patient's clinical status and verify that artifact or lead dislodgement is not causing the apparent pause.

Question 3

Which lead configuration provides the best view of inferior wall ischemia during continuous monitoring?

Accepted Answer

Lead II

Answer

Lead II best visualizes the inferior wall because it runs parallel to the inferiorly directed depolarization vector supplied by the right coronary artery.

Question 4

A monitored patient suddenly develops a wide-complex tachycardia at 180 bpm with AV dissociation. The most likely diagnosis is:

Accepted Answer

Ventricular tachycardia

Answer

AV dissociation is a strong criterion for ventricular tachycardia and differentiates it from most SVTs with aberrant conduction.

Question 5

What is the correct energy setting for the first synchronized cardioversion attempt in a hemodynamically stable patient with atrial flutter?

Accepted Answer

50–100 J biphasic

Answer

Atrial flutter is highly responsive to low-energy synchronized cardioversion, typically beginning at 50–100 J with a biphasic waveform.
