BLS CPR Techniques & Procedures 2

Question 1

When performing CPR on an adult, what is the correct hand placement for chest compressions?

Accepted Answer

On the lower half of the sternum

Answer

Compressions should be delivered to the lower half of the sternum (breastbone) to effectively compress the heart.

Question 2

What is the recommended compression-to-ventilation ratio for a lone rescuer performing CPR on a child?

Accepted Answer

30:2

Answer

A lone rescuer uses 30:2 for children, the same ratio as for adults, to simplify training.

Question 3

During CPR, which of the following best describes 'full chest recoil'?

Accepted Answer

Allowing the chest to fully rise between compressions

Answer

Full chest recoil means allowing the chest to completely return to its normal position after each compression so the heart can refill with blood.

Question 4

A rescuer notices they are delivering rescue breaths too quickly. What is the most likely consequence?

Accepted Answer

Gastric inflation and risk of aspiration

Answer

Breaths delivered too quickly or forcefully cause air to enter the stomach, leading to gastric inflation and risk of vomiting and aspiration.

Question 5

In a two-rescuer adult CPR scenario, when should the compressor role be switched?

Accepted Answer

Every 2 minutes or 5 cycles

Answer

Rescuers should switch the compressor role every 2 minutes (approximately 5 cycles of 30:2) to prevent fatigue and maintain compression quality.
