The Ultimate NCLEX Catalyst: 100 High-Yield Questions with Comprehensive Rationales, WITH SCREENSHOTS TO MATCHCardiopulmonary Resuscitation (CPR) & Basic Life Support (BLS) 1. A nurse finds an unresponsive adult patient in the hospital hallway. After calling for help and checking for a pulse, the nurse determines there is no pulse. What is the next priority action? A. Open the airway with a head-tilt-chin-lift. B. Provide two rescue breaths. C. Begin chest compressions at a rate of 80 per minute. D. Begin high-quality chest compressions at a rate of 100-120 per minute. Rationale: The C-A-B sequence (Compressions, Airway, Breathing) is the standard for CPR. Circulation is the priority to perfuse vital organs. Compressions should be initiated immediately at a rate of 100-120 per minute. 2. The American Heart Association (AHA) uses the C-A-B sequence for CPR. What is the primary reason for this change from the previous A-B-C sequence? A. To ensure the airway is clear before ventilations. B. To decrease the time to first chest compression. C. To allow for easier recall of the steps. D. To prioritize breathing as the most vital function. Rationale: The C-A-B sequence was adopted to minimize the delay in starting chest compressions, which are crucial
