What is the recommended compression depth for an adult during CPR?
At least 1 inch (2.5 cm)
At least 3 inches (7.5 cm)
At least 2 inches (5 cm)
At least 4 inches (10 cm)
Adult chest compressions should be at least 2 inches (5 cm) deep to generate adequate blood flow. Shallower compressions will not effectively circulate blood to vital organs.
Where should you place your hands when performing chest compressions on an adult?
Directly over the xiphoid process
On the upper third of the sternum
On the lower half of the sternum
Two finger-widths to the left of the sternum
Hand placement on the lower half of the sternum ensures compressions press on the heart between the sternum and spine. Placing hands elsewhere risks injury or ineffective compressions.
In adult CPR, what is the recommended compression-to-ventilation ratio for a single rescuer?
30 compressions to 1 breath
15 compressions to 2 breaths
30 compressions to 2 breaths
15 compressions to 1 breath
The standard single-rescuer adult CPR ratio is 30 compressions followed by 2 breaths to balance circulation and oxygenation. Other ratios are outdated or intended for pediatric scenarios.
What is the first action you should take when you find an unresponsive adult on the floor?
Open the airway with a head tilt-chin lift
Begin chest compressions immediately
Tap the person's shoulder and shout to check responsiveness
Call emergency medical services
Checking responsiveness by tapping and shouting is the first step to determine if CPR is needed. Only after confirming unresponsiveness do you call for help and begin chest compressions.
At what rate should chest compressions be performed on an adult?
120 to 140 compressions per minute
80 to 100 compressions per minute
100 to 120 compressions per minute
60 to 80 compressions per minute
The recommended compression rate for adult CPR is 100 - 120 compressions per minute to maintain adequate perfusion. Slower or faster rates reduce the effectiveness of compressions.
Which of the following signs indicates that you should begin CPR on an adult?
Chest pain without loss of consciousness
Slow, shallow breathing
Vomiting repeatedly
No response to tapping and not breathing normally
CPR is indicated when the victim is unresponsive and not breathing normally. Other signs like chest pain alone do not require immediate CPR if the person is conscious and breathing.
What is the correct sequence of steps in adult CPR according to CAB protocol?
Breathing, Circulation, Airway
Airway, Circulation, Breathing
Circulation, Airway, Breathing
Airway, Breathing, Circulation
The CAB sequence prioritizes chest compressions (Circulation) first, then opening the Airway and delivering Breaths. This ensures blood flow is restored quickly.
During a primary assessment, how long should you check for normal breathing in an adult?
Only 3 seconds minimum
At least 30 seconds
Up to 60 seconds
Up to 10 seconds
You should check for breathing for no more than 10 seconds to minimize delays in starting chest compressions. Longer assessments reduce the time available for lifesaving measures.
What technique is used to open the airway of an adult without suspected spinal injury?
Head tilt - chin lift
Tracheal extension
Jaw-thrust maneuver
Neck hyperextension
The head tilt - chin lift is the recommended airway-opening method for adults without spinal injury. It lifts the tongue away from the back of the throat to clear the airway.
If rescue breaths do not make the chest rise during CPR, what should you do?
Stop CPR and wait for EMS
Proceed to compressions without more breaths
Reposition the head and chin then retry
Increase the force of your breath
Repositioning the head and chin can correct an obstructed airway and allow effective rescue breaths. Forcing breaths or stopping CPR delays oxygen delivery.
Which action is most important before delivering a shock with an AED?
Wear protective gloves
Dry your own hands thoroughly
Ensure no one is touching the patient
Remove any jewelry from the patient
Making sure no one is in contact with the patient prevents accidental injury during defibrillation. Other steps are good practice but do not protect rescuers during the shock.
Which pulse should be checked to assess circulation in an unresponsive adult?
Radial pulse
Brachial pulse
Femoral pulse
Carotid pulse
The carotid pulse is the most reliable central pulse in an adult. Peripheral pulses like radial or brachial may be difficult to feel during cardiac arrest.
What is the recommended intervention for a conscious adult who cannot cough and is choking?
Back slaps only
Rescue breathing
Abdominal thrusts (Heimlich maneuver)
Continuous chest compressions
Abdominal thrusts are recommended for a conscious adult with a severe airway obstruction. They apply upward pressure to expel the object causing the choking.
After performing two minutes of CPR on an adult, what should rescuers do next if an AED is available?
Pause and analyze the rhythm with the AED
Continue compressions without pause
Wait another two minutes before analyzing
Manually check the pulse for 30 seconds
After about two minutes of CPR, you should pause compressions briefly to allow the AED to analyze the heart rhythm. This step guides whether a shock is needed.
How can rescuers minimize gastric inflation during rescue breathing in adult CPR?
Deliver each breath over 3 - 4 seconds
Provide rapid, forceful breaths
Use maximal volume on each breath
Deliver each breath over 1 second just until the chest rises
Giving slow breaths over 1 second with just enough volume to see chest rise reduces air entering the stomach. Excessively fast or forceful breaths increase gastric inflation risk.
During two-rescuer adult CPR, how often should rescuers switch roles to reduce fatigue?
Only after AED use
Every 30 compressions
Every 5 minutes
Every 2 minutes
Switching compressors every 2 minutes helps maintain high-quality, effective chest compressions. Shorter or longer intervals can reduce performance and increase rescuer fatigue.
If a spinal injury is suspected in an unresponsive adult, what airway technique should be used?
Jaw-thrust maneuver without head tilt
Tracheal extension
Head tilt - chin lift
Neck hyperextension
The jaw-thrust maneuver opens the airway without moving the cervical spine, reducing risk of spinal injury. Head tilt - chin lift risks additional spinal damage in this scenario.
Why is it critical to avoid excessive ventilation during adult CPR?
It prevents gastric distension completely
It increases intrathoracic pressure and reduces venous return
It speeds up return of spontaneous circulation
It improves coronary perfusion
Excessive ventilation raises intrathoracic pressure, which impedes venous return to the heart and reduces cardiac output. Controlled ventilation balances oxygenation and circulation.
When alone with a drowning adult victim, what is the recommended CPR approach before calling emergency services?
Give chest compressions only and then call EMS
Administer rescue breaths only until help arrives
Leave immediately to call EMS without giving CPR
Perform about five cycles of CPR (≈2 minutes) before leaving to call EMS
For drowning victims, rescuers provide approximately five cycles of CPR before leaving to call EMS, since hypoxia is the primary issue. Early ventilations improve outcomes in drowning cases.

Cheat Sheet

  1. Recognize the signs of cardiac arrest - Cardiac arrest strikes without warning, leading to sudden collapse, loss of consciousness, and absent or abnormal breathing. Quick identification of these signs is your first step to saving a life. Stay calm, shout for help, and call emergency services at once. Read the full Heart.org guide
  2. Ensure scene safety before initiating CPR - Never rush in blindly; scan the environment for hazards like traffic, electrical wires, or unstable structures. Securing the scene protects you and the victim, ensuring uninterrupted lifesaving efforts. Once clear, don protective gloves if available and approach safely. Mayo Clinic first-aid tips
  3. Perform high-quality chest compressions - Place the heel of one hand on the center of the chest, interlock your fingers, and push hard and fast at a rate of 100 - 120 compressions per minute, pressing at least 2 inches deep. Let the chest fully recoil between each push to maximize blood flow. Picture dancing to the Bee Gees' "Stayin' Alive" to keep rhythm! Explore CPR basics at Heart.org
  4. Open the airway with head-tilt, chin-lift - Gently tilt the victim's head back and lift the chin upward to align the airway. This simple maneuver clears the passage for rescue breaths and improves ventilation. Avoid excessive force to prevent neck injury. Learn more from Mayo Clinic
  5. Deliver effective rescue breaths - After every 30 compressions, pinch the nose, seal your mouth over theirs, and give two 1-second breaths, watching for the chest to rise. Proper seal and breath timing ensure oxygen reaches the lungs. If you're unsure, continue hands-only CPR until help arrives. Mayo Clinic ventilation guide
  6. Use an Automated External Defibrillator (AED) promptly - As soon as an AED arrives, turn it on and follow voice prompts to attach pads and deliver a shock if advised. Early defibrillation greatly improves survival, so don't delay. Continue CPR between shocks as instructed. AED instructions at Heart.org
  7. Minimize interruptions during CPR - Keeping pauses under 10 seconds maintains blood flow to vital organs. Coordinate with helpers to switch compressors every two minutes, reducing fatigue-driven delays. Consistent compressions are key to better outcomes. Review CPR guidelines
  8. Ensure proper hand placement - Position your hands on the lower half of the sternum, avoiding the xiphoid process to reduce injury risk. Centering on the breastbone optimizes compression depth and effectiveness. Keep elbows locked and shoulders over your hands for maximum force. Hand placement details
  9. Recognize when to stop CPR - Stop only if the person shows clear signs of life, trained professionals take over, or you're physically unable to continue. Premature cessation can harm the victim, so stay committed unless directed otherwise. Debrief with responders for improvement tips. When to stop CPR
  10. Stay updated with CPR guidelines - CPR science evolves, so refresh your skills every 1 - 2 years through accredited courses or online updates. Regular practice boosts confidence and ensures you're following the latest protocols. Share your knowledge and keep your community prepared! Stay current at Heart.org
