Free BLS CPR Techniques & Procedures Questions and Answers

Question 1

What is the recommended rate for chest compressions during adult CPR?

Accepted Answer

100–120 compressions per minute

Answer

According to current Basic Life Support (BLS) guidelines, the recommended rate for chest compressions during adult CPR is 100 to 120 compressions per minute. This specific rate ensures adequate blood flow to vital organs, maximizing the effectiveness of CPR. Maintaining this rhythm is crucial for patient outcomes.

Question 2

What is the depth of chest compressions for an adult during CPR?

Accepted Answer

2 inches

Answer

For effective adult CPR, chest compressions should be delivered to a depth of at least 2 inches (5 cm). This depth is critical to adequately compress the heart and circulate blood to the brain and other vital organs. However, compressions should not exceed 2.4 inches (6 cm) to avoid injury.

Question 3

When performing CPR, what is the correct compression-to-ventilation ratio for a single rescuer?

Accepted Answer

30:2

Answer

For a single rescuer performing CPR on an adult, the correct compression-to-ventilation ratio is 30 compressions followed by 2 rescue breaths. This ratio prioritizes chest compressions, which are the most critical component of CPR for maintaining blood flow. It ensures a balance between circulating blood and providing oxygen.

Question 4

Which action is the first step in the BLS Assessment?

Accepted Answer

Check responsiveness

Answer

The first step in the BLS Assessment is to check for responsiveness by tapping the victim and shouting, 'Are you okay?' This initial assessment determines if the victim is conscious and requires further intervention. If unresponsive, the rescuer then proceeds to call for help and assess breathing and pulse.

Question 5

Which method is used to open the airway in an unresponsive victim without suspected trauma?

Accepted Answer

Head tilt–chin lift

Answer

The head tilt–chin lift maneuver is the standard method for opening the airway in an unresponsive victim when there is no suspicion of spinal trauma. This technique lifts the tongue off the back of the throat, which is the most common cause of airway obstruction in an unconscious person. It ensures a clear path for air to enter the lungs.
