Free BLS Adult, Child & Infant Resuscitation Questions and Answers

Question 1

What is the recommended compression depth for adults during CPR?

Accepted Answer

At least 2 inches

Answer

For effective adult CPR, chest compressions must be deep enough to adequately circulate blood to vital organs. The recommended depth is at least 2 inches (5 cm), but no more than 2.4 inches (6 cm). Compressing too shallowly will not provide sufficient blood flow, while compressing too deeply can cause injury, making proper depth crucial.

Question 2

What is the compression-to-ventilation ratio for single-rescuer infant CPR?

Accepted Answer

30:2

Answer

For single-rescuer infant CPR, the compression-to-ventilation ratio is 30 compressions followed by 2 breaths. This ratio is consistent across all age groups (adults, children, and infants) for single rescuers, simplifying the protocol. It ensures adequate blood flow and oxygenation, which are both critical for an infant in cardiac arrest.

Question 3

Where should you place your hands for chest compressions on a child?

Accepted Answer

On the sternum, just below the nipple line

Answer

For child CPR, compressions should be delivered on the lower half of the sternum, just below the nipple line. This placement ensures that compressions are delivered over the heart, maximizing effectiveness while minimizing the risk of injury to other organs or ribs. One or two hands can be used depending on the child's size to achieve the correct depth.

Question 4

What is the preferred method of chest compressions for 2-rescuer infant CPR?

Accepted Answer

Encircling thumbs technique

Answer

For 2-rescuer infant CPR, the encircling thumbs technique is preferred. This method involves rescuers encircling the infant's chest with their hands and using their thumbs to compress the sternum. It provides better compression depth and force, reduces rescuer fatigue, and allows for better coordination between rescuers, leading to more effective CPR.

Question 5

What is the appropriate compression depth for a child?

Accepted Answer

About 2 inches or 1/3 chest depth

Answer

For effective child CPR, compressions should be approximately 2 inches (5 cm) deep, or about one-third the depth of the child's chest. This depth ensures adequate blood circulation to vital organs without causing excessive force or injury. It's crucial to allow for complete chest recoil between compressions to allow the heart to refill with blood.
