ACLS BLS and High-Quality CPR 2

Question 1

During CPR on an adult, what is the recommended compression-to-ventilation ratio when two rescuers are present and an advanced airway has NOT been placed?

Accepted Answer

30:2

Answer

The 30:2 compression-to-ventilation ratio is used for adults until an advanced airway is placed, regardless of the number of rescuers.

Question 2

Which action is MOST important in minimizing interruptions during chest compressions?

Accepted Answer

Pausing compressions only for rhythm checks and defibrillation

Answer

Minimizing all pauses to rhythm checks and defibrillation preserves coronary perfusion pressure generated by compressions.

Question 3

A patient in cardiac arrest has a continuous waveform capnography reading of 8 mmHg despite ongoing CPR. What does this indicate?

Accepted Answer

CPR quality is poor and should be improved

Answer

ETCO2 below 10 mmHg during CPR indicates poor cardiac output and signals the need to improve compression quality.

Question 4

When providing rescue breaths during CPR, each breath should be delivered over how long a period?

Accepted Answer

1 second

Answer

Each rescue breath should be delivered over 1 second to produce visible chest rise without causing gastric inflation.

Question 5

A 45-year-old collapses. You find no pulse after 10 seconds of checking. What is your FIRST action?

Accepted Answer

Begin chest compressions

Answer

Chest compressions should be started immediately upon confirming pulselessness; CPR begins with compressions (C-A-B sequence).
