BLS Adult, Child & Infant Resuscitation 5

Question 1

A rescuer is providing CPR to an adult and becomes fatigued. How often should rescuers switch roles to maintain compression quality?

Accepted Answer

Every 2 minutes (approximately 5 cycles)

Answer

Rescuers should switch the compressor role every 2 minutes (5 cycles) to prevent fatigue and maintain high-quality compressions.

Question 2

What does 'allow full chest recoil' mean in the context of CPR?

Accepted Answer

Let the chest completely return to its natural position after each compression

Answer

Full recoil means removing all pressure so the chest returns fully to its resting position, allowing the heart to refill with blood.

Question 3

An infant is found pulseless and not breathing. The rescuer is alone. What is the correct compression-to-ventilation ratio?

Accepted Answer

30:2

Answer

A single rescuer uses a 30:2 ratio for infant CPR, switching to 15:2 only when a second rescuer is available.

Question 4

Which of the following is a sign that CPR is effective?

Accepted Answer

Visible chest rise with each rescue breath and palpable pulse with compressions

Answer

Signs of effective CPR include visible chest rise with each ventilation and a palpable carotid or femoral pulse felt during compressions.

Question 5

When is it appropriate to stop CPR once started?

Accepted Answer

When the scene becomes unsafe, advanced providers take over, or the victim shows signs of life

Answer

BLS rescuers should continue CPR until the scene becomes unsafe, trained advanced providers assume care, an AED advises a shock, or the victim shows obvious signs of life.
