Basic life support exam a answers 25 questions
Immediately assess the situation for responsiveness. If the person is unresponsive, check for a pulse and normal breathing. If no pulse is detected, begin chest compressions at a depth of at least 2 inches and a rate of 100-120 compressions per minute. Provide rescue breaths at a ratio of 30 compressions to 2 breaths.
When an AED becomes available, apply the pads to the chest as directed. Ensure the area is clear and allow the machine to assess the need for a shock. If a shock is advised, deliver it and continue compressions. After every 2 minutes, reassess the victim’s pulse and breathing.
Always stay focused on the victim’s circulation. If they begin breathing normally, turn them to a recovery position and monitor their airway. If they stop breathing again, resume chest compressions. Do not stop until trained professionals arrive or the person shows signs of recovery.
If bleeding occurs, apply direct pressure to the wound. Maintain pressure until help arrives, ensuring the person remains stable and protected from further harm.

24. Recheck the pulse and breathing after every 2 minutes of CPR to assess progress.
25. Review and practice all steps regularly to ensure readiness in case of an emergency situation.
Understanding the Key Concepts of CPR in the BLS Exam
Immediately assess the situation and ensure the environment is safe before approaching a victim. If the person is unresponsive, activate emergency medical services and begin chest compressions. Use the heel of one hand in the center of the chest, placing the other hand on top, and perform compressions at a depth of at least 2 inches and a rate of 100-120 per minute. Maintain a consistent rhythm, allowing for full chest recoil between compressions.
If the victim is not breathing or only gasping, provide rescue breaths. Open the airway using the head-tilt, chin-lift maneuver, then deliver a breath that makes the chest rise visibly. Give 2 breaths, each lasting about 1 second, after every 30 chest compressions.
Continue this cycle of chest compressions and rescue breaths until emergency responders arrive, or the person shows signs of recovery, such as breathing normally. If an automated external defibrillator (AED) is available, turn it on and follow the prompts immediately after the first few cycles of CPR.

Recognizing the Signs of Cardiac Arrest in the Exam Setting
If a person suddenly collapses and becomes unresponsive, check for the absence of normal breathing. An individual in cardiac arrest will not show signs of spontaneous breathing. Rapidly assess for a pulse; if absent, begin chest compressions immediately. Shallow, irregular breathing or gasping may be mistaken for signs of life, but this is not an indication of effective breathing. Focus on responsiveness, pulse, and breathing patterns to differentiate from other medical conditions.
Watch for the loss of consciousness or the person’s inability to respond to verbal or physical stimuli. An unresponsive individual, who does not react to stimuli or show any movement, is a strong indicator of cardiac arrest. In some cases, you may observe abnormal body movements such as jerking or twitching, which is a result of inadequate blood flow to the brain, often confused with seizures. These should not delay starting chest compressions if a pulse is absent.
Assessing the person’s skin is also helpful. If the skin is pale or bluish in color, this suggests poor oxygen circulation, a common result of a sudden cessation of heart function. Additionally, check for any signs of heavy sweating, which could be a symptom related to heart failure or shock. Monitor for any abnormalities in the breathing rhythm, such as slow, labored breaths, as this may also signal a cardiovascular emergency requiring immediate intervention.
Proper Chest Compression Techniques: What You Need to Know
Deliver compressions at a depth of at least 2 inches (5 cm) for adults, ensuring proper chest recoil between compressions. This allows the heart to refill with blood, maximizing the effectiveness of each compression. The rate should be 100 to 120 compressions per minute, matching the beat of the song “Stayin’ Alive” by the Bee Gees, a helpful guide for maintaining the proper pace.
Place the heel of one hand on the center of the chest, just below the breastbone. Interlace your fingers and keep your elbows straight, using your upper body weight to apply downward force. Avoid lifting your hands off the chest between compressions, as this could compromise blood flow. Hands should remain firmly on the chest throughout the process, ensuring full depth of compression.
Ensure the victim is lying flat on a firm surface before starting compressions, as this maximizes the efficiency of the chest movements. Reassess every few minutes to monitor any signs of circulation or response from the victim.
For children, the compression depth is about 1/3 the depth of the chest, approximately 2 inches (5 cm). For infants, use two fingers to compress the chest to a depth of about 1.5 inches (4 cm). Always adjust your technique according to the age and size of the victim.
Chest compressions should not be interrupted for more than 10 seconds. In cases where an automated external defibrillator (AED) is available, minimize interruptions by starting compressions again immediately after the shock is delivered.
Managing Ventilation and Breathing Challenges During the Exam
Ensure an open airway by tilting the head backward and lifting the chin. For suspected neck injuries, use the jaw-thrust maneuver instead. If the person is unresponsive and not breathing, deliver two rescue breaths after ensuring the airway is clear.
If chest rise is not visible after the initial breaths, reposition the head and attempt again. Avoid excessive force during ventilation to prevent gastric inflation, which can lead to aspiration. If ventilation continues to be ineffective, consider the presence of an obstruction and attempt to clear it using the Heimlich maneuver or other appropriate techniques.
For individuals with a suspected respiratory challenge, use a bag-valve mask (BVM) for more effective ventilation. Check for leaks and ensure a proper seal. If available, supplemental oxygen should be administered to improve oxygenation during the assessment.
If the patient shows signs of respiratory distress or altered breathing patterns, closely monitor the breathing rate and depth. Adjust ventilations as needed, ensuring a consistent rate of 10-12 breaths per minute for adults and slightly faster rates for children and infants. Continuously reassess ventilation efficacy and airway patency throughout the process.
How to Approach Post-Resuscitation Care in the BLS Exam
Once the victim shows signs of recovery, prioritize continuous monitoring of their airway, breathing, and circulation. Check for any changes in the person’s condition and adjust interventions accordingly. Focus on stabilizing vital signs before moving to the next phase.
- Ensure the airway remains open, and if necessary, place the person in the recovery position to prevent aspiration.
- Monitor the breathing rate and rhythm, and be ready to administer rescue breaths if needed.
- Check pulse and skin color; if circulation is inadequate, perform chest compressions again until help arrives.
- Use an automated external defibrillator (AED) if available, especially if the person is still unresponsive and in need of shock.
After regaining a pulse, focus on preventing secondary complications. Keep the individual warm and continue monitoring for any signs of deterioration. Ensure they receive advanced care as soon as possible to address underlying issues.
- If trained, administer oxygen as needed to improve oxygenation and prevent hypoxia.
- Continuously reassess the patient’s status until professional medical help takes over.
- Do not attempt to give fluids or medications unless instructed by a healthcare provider.
In the final stages, keep the patient calm and reassured while awaiting additional medical assistance. Always provide detailed information to responders about the care given and any changes in the patient’s condition.
