Basic Life Support (BLS) Certification – YMCA HSI Exam Prep 35 Questions | CPR, AED Use, Rescue Breathing | HSI YMCA

This document contains approximately 35 HSI YMCA Basic Life Support (BLS) exam questions with expert-verified answers designed to help students review essential life-saving procedures used in emergency response. The material is presented in an exam-style question-and-answer format covering CPR techniques, AED operation, rescue breathing procedures, and the recognition and management of cardiac arrest in adults, children, and infants. These practice questions are useful for learners preparing for BLS certification or recertification courses offered through organizations such as HSI and YMCA training programs. The content aligns with concepts commonly taught in BLS training manuals such as the HSI Basic Life Support Training Guide and American Heart Association BLS Provider Manual. The document emphasizes the steps required for delivering high-quality cardiopulmonary resuscitation (CPR), including maintaining proper compression depth, allowing full chest recoil between compressions, and minimizing interruptions during resuscitation efforts. For example, the material explains that allowing complete chest recoil between compressions is critical because it allows the heart to refill with blood before the next compression. Another major focus of the document is the chain of survival, which describes the sequence of actions required to improve survival outcomes in cardiac arrest emergencies. Key links include early recognition of cardiac arrest, activation of emergency medical services (EMS), early CPR, rapid defibrillation using an automated external defibrillator (AED), advanced life support, and recovery support after hospital care. The document also reviews CPR procedures for different age groups, including infants, children, and adults. Students learn techniques such as the heel-of-one-hand compression method, which can be used when performing chest compressions on larger infants or when providers have difficulty achieving adequate compression depth. The material also discusses infant pulse assessment techniques, including locating the brachial pulse inside the upper arm between the elbow and shoulder. Another important section examines AED usage during resuscitation, explaining that rescuers should continue high-quality chest compressions while the AED charges after pads are applied. Rapid defibrillation is especially critical when patients experience life-threatening rhythms such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). The document also covers airway management and ventilation techniques, including rescue breathing and bag-mask ventilation. For example, when ventilating a child with a bag-mask device, rescuers should deliver one breath every 2–3 seconds, with each breath lasting about one second while observing chest rise. Additionally, when an advanced airway such as an endotracheal tube is in place during cardiac arrest, ventilation should be delivered approximately once every 6 seconds. Several clinical scenarios in the document demonstrate how BLS providers respond to emergency situations. Examples include responding to opioid overdose by providing ventilation and administering naloxone (Narcan) according to local protocols, recognizing abnormal breathing sounds such as gasping or snoring respirations, and initiating CPR immediately when a patient has no pulse. The material also explains patient assessment procedures, including the requirement that rescuers should spend no more than 10 seconds assessing breathing and pulse simultaneously before beginning CPR. Minimizing delays in chest compressions significantly improves circulation and survival chances during cardiac arrest.
