Question 1

Which feature of modern AEDs provides real-time feedback to rescuers during CPR?

Accepted Answer

Impedance-based chest compression depth and rate monitoring

Answer

Modern AEDs use transthoracic impedance sensing to detect chest compressions and provide real-time audio/visual feedback on depth and rate.

Question 2

End-tidal CO2 (ETCO2) monitoring during cardiac arrest is MOST useful for:

Accepted Answer

Confirming correct tracheal tube placement and assessing CPR quality

Answer

ETCO2 confirms endotracheal tube placement and reflects cardiac output during CPR; a sudden rise often indicates return of spontaneous circulation.

Question 3

A mechanical CPR device such as the LUCAS or AutoPulse is MOST appropriate in which scenario?

Accepted Answer

Prolonged resuscitation during patient transport or cardiac catheterization

Answer

Mechanical CPR devices deliver consistent compressions when sustained high-quality manual CPR is impractical, such as during transport or in the cath lab.

Question 4

When using a defibrillator's synchronize mode for cardioversion, the shock is timed to which part of the cardiac cycle?

Accepted Answer

R wave

Answer

Synchronized cardioversion delivers the shock on the R wave to avoid the vulnerable T-wave period, which could induce ventricular fibrillation.

Question 5

Point-of-care ultrasound (POCUS) during cardiac arrest can identify all of the following EXCEPT:

Accepted Answer

Ventricular fibrillation on the monitor

Answer

VF is diagnosed on the cardiac monitor/ECG, not by ultrasound; POCUS identifies reversible causes and confirms true PEA (no wall motion).
