CMT CMT Emergency Response and ACLS Protocols

Question 1

When a cardiac monitor technician identifies ventricular fibrillation on a remote telemetry unit, the FIRST action is to:

Accepted Answer

Notify the bedside nurse or charge nurse immediately

Answer

The CMT's first action is immediate notification of the bedside nurse since the technician cannot physically assess or treat the patient.

Question 2

Per ACLS guidelines, what is the recommended energy for the first defibrillation shock for ventricular fibrillation with a biphasic defibrillator?

Accepted Answer

120–200 joules (manufacturer recommended)

Answer

ACLS recommends 120–200 joules (biphasic, per manufacturer) for the first shock in VF, as biphasic waveforms are more effective at lower energies.

Question 3

During CPR, how frequently should the cardiac rhythm be checked?

Accepted Answer

Every 2 minutes (after each 5 cycles of CPR)

Answer

ACLS protocol calls for rhythm checks every 2 minutes (after 5 cycles of 30:2 CPR) to minimize interruptions in chest compressions.

Question 4

A telemetry patient goes into asystole. What rhythm does the CMT confirm before reporting to the team?

Accepted Answer

Check two leads to confirm true asystole, not fine VF or lead disconnect

Answer

Asystole must be confirmed in at least two leads to differentiate true asystole from fine VF or artifact from lead disconnection.

Question 5

What is the recommended compression depth for adult CPR per current AHA guidelines?

Accepted Answer

At least 2 inches (5 cm), not exceeding 2.4 inches

Answer

AHA guidelines specify adult chest compressions should be at least 2 inches (5 cm) but not exceeding 2.4 inches (6 cm) to optimize perfusion.
