What does CPR stand for?
Cardiopulmonary Resuscitation
Circulatory Pulmonary Revival
Cardiac Pressure Response
Cardio Pulmonary Response
CPR stands for Cardiopulmonary Resuscitation, which combines chest compressions and rescue breaths to maintain circulation and oxygenation. It is the foundation of basic life support. Early CPR can double or triple survival rates in out-of-hospital cardiac arrest situations. .
What is the first step in the adult Chain of Survival?
Delivering rescue breaths
Calling emergency services (e.g., 911)
Using an AED
Starting chest compressions
The first link in the Chain of Survival is early recognition of cardiac arrest and calling emergency services. Getting professional help on the way quickly is critical for patient outcomes. Immediate activation of EMS ensures advanced care is coming. .
At what rate should you perform chest compressions on an adult?
80 to 100 compressions per minute
120 to 140 compressions per minute
100 to 120 compressions per minute
60 to 80 compressions per minute
Current guidelines recommend a chest compression rate of 100 to 120 compressions per minute for adults. This rate maximizes blood flow without causing excessive fatigue. Performing compressions at this pace improves the chance of successful resuscitation. .
Where do you place your hands when performing chest compressions on an adult?
On the upper third of the sternum
Just above the xiphoid process
On the ribs at the mid-axillary line
Center of the chest on the lower half of the sternum
Proper hand placement is in the center of the chest on the lower half of the sternum. This position directs force over the heart to optimize blood flow. Incorrect placement can reduce the effectiveness of compressions or cause injury. .
What is the minimum recommended depth of chest compressions for an adult?
At least 1.5 inches (3.8 cm)
At least 2 inches (5 cm)
At least 3 inches (7.6 cm)
At least 1 inch (2.5 cm)
Guidelines recommend a chest compression depth of at least 2 inches (5 cm) for adults. Adequate depth helps generate sufficient blood flow during cardiac arrest. Compressing too shallowly reduces circulation and survival odds. .
What compression-to-ventilation ratio should a single rescuer use for adult CPR?
30:2
30:1
15:2
15:1
A single rescuer performing adult CPR should use a ratio of 30 compressions to 2 breaths. This balance emphasizes chest compressions to maintain circulation while providing periodic ventilations. It is a core part of current BLS guidelines. .
When using an AED, what must you ensure before delivering a shock?
The pads are overheated
No one is touching the patient
The patient is cold
The battery icon is green
Before delivering a shock, you must ensure that no one is touching the patient to prevent accidental injury. The AED will typically issue a voice prompt to "stand clear" before shock delivery. This safety step protects both rescuers and bystanders. .
At what maximum duration should you pause chest compressions to check for pulse and rhythm?
5 seconds
20 seconds
15 seconds
10 seconds
Interruptions in chest compressions should be limited to no more than 10 seconds when checking pulse and rhythm. Minimizing pauses helps maintain coronary perfusion pressure and increases the chance of return of spontaneous circulation. Prolonged pauses reduce CPR effectiveness. .
For two-rescuer child CPR, what compression-to-ventilation ratio is recommended?
30:2
15:1
30:1
15:2
When two rescuers are available for child CPR, a ratio of 15 compressions to 2 breaths is recommended. This ratio increases the frequency of ventilations, which is important in pediatric resuscitation. Single rescuers should continue with 30:2. .
Which pulse site is recommended for checking circulation in an infant?
Radial artery
Femoral artery
Carotid artery
Brachial artery
The brachial artery, located on the inside of the upper arm between the infant's elbow and shoulder, is the recommended site for pulse checks. It's accessible and reliable in infants. Other sites are more difficult to palpate in this age group. .
How should AED pads be placed for an infant if pediatric pads are unavailable?
One pad on the chest and one on the abdomen
One pad on the center of the chest and one on the back (antero-posterior)
Both pads on the front of the chest, high and low
One pad under each armpit
If pediatric pads are not available, place one AED pad on the front center of the infant's chest and the other on the back between the shoulder blades (antero-posterior position). This ensures the shock travels through the heart. Adult pad placement on small chests may cause pad overlap, so this positioning is recommended. .
During two-rescuer CPR, how often should rescuers switch roles to avoid fatigue?
After 3 minutes
After 5 cycles or about 2 minutes
Every minute
After 10 cycles
Rescuers should switch roles every 5 cycles of CPR, which takes about 2 minutes, to minimize fatigue and maintain high-quality compressions. Frequent switches help sustain compression depth and rate. Clear communication during handover prevents pauses. .
What is the recommended compression depth for a child?
At least 2 inches (5 cm)
At least 2.5 inches (6.4 cm)
About one-third the anterior-posterior chest depth, roughly 2 inches (5 cm)
About 1 inch (2.5 cm)
For children, compressions should be about one-third of the chest's anterior-posterior depth, which is roughly 2 inches (5 cm). This proportionate depth ensures effective blood flow without causing injury. Compression rate remains 100-120 per minute. .
Which situation is a contraindication for using an AED?
Patient is wet
Patient lying on a metal surface
Presence of flammable gases or materials around the patient
Patient has an implanted pacemaker
AED use is contraindicated in environments with flammable gases or materials because the electrical discharge could ignite a fire. Patients on metal surfaces or with pacemakers can still receive AED shocks if positioned correctly. Wet patients should be dried off, but this is not an absolute contraindication. .
In which situation should an AED be applied before initiating chest compressions?
When you witness an adult suddenly collapse and an AED is immediately available
When a bystander is untrained in CPR
When emergency services are already on the phone
When the patient is breathing abnormally
If you witness an adult suddenly collapse and an AED is immediately available, you should apply it before starting compressions to rapidly analyze the rhythm and deliver a shock if needed. This minimizes time to defibrillation, which is critical for survival in witnessed cardiac arrest. Other situations still require starting CPR first. .

Cheat Sheet

  1. Chain of Survival -

    Master the five links of the American Heart Association's Chain of Survival - early recognition and calling 911, prompt CPR, rapid defibrillation, effective advanced life support, and integrated post - cardiac arrest care (AHA, 2020). Use the CAB mnemonic - Compressions, Airway, Breathing - to keep your sequence crisp in any cpr and first aid quiz scenario. This foundational concept often appears in free cpr test questions and answers to reinforce life”saving priorities.

  2. Compression Depth & Rate -

    Deliver chest compressions at least 2 inches deep at a rate of 100 - 120 compressions per minute for adults, as recommended by the American Heart Association (AHA Guidelines, 2020). A handy mnemonic is to "Stayin' Alive" by the Bee Gees, which clocks in near 103 bpm and helps maintain rhythm. These specifics are tested in cpr example test items and cardiopulmonary resuscitation questions answers to ensure high”quality CPR.

  3. AED Usage Steps -

    Follow the AHA's AED sequence: Power on, Attach pads, Don't touch the patient, Analyze rhythm, and Shock if advised (PAD acronym). This simple algorithm reduces hesitation and speeds defibrillation in real emergencies. You'll find these steps peppered throughout answers to first aid cpr test questions and cpr and first aid quiz modules.

  4. Rescue Breaths & Compression Ratio -

    Use a 30:2 compression”to”ventilation ratio for adults, ensuring each rescue breath delivers roughly 500 - 600 mL of air (about the size of two thumbs). Perform a proper head”tilt, chin”lift to open the airway and watch for chest rise to confirm effective ventilations. This ratio and technique are cornerstones of free cpr test questions and answers to validate your airway skills.

  5. Scene Safety & Emergency Recognition -

    Always assess scene safety first: ensure no hazards before approaching, then check the victim's responsiveness by tapping and shouting. If unresponsive, call 911 immediately (or shout for help) and retrieve an AED if available. This initial assessment is a staple in any free cpr test questions and answers or cpr example test to ensure both rescuer and victim safety.
