Advanced Life Support (ALS) Online Session Final Exam Questions and Answers | Latest Version | 2024/2025 | Already Passed What initial intervention is typically performed for a hemodynamically stable patient presenting with a narrow-complex supraventricular tachyarrhythmia? Vagal maneuvers are usually attempted first. If ineffective, adenosine may be administered. When interpreting a capnogram waveform, which segment indicates the start of exhalation? The A–B segment on the capnogram represents the beginning of exhalation. After unsuccessful attempts with atropine and transcutaneous pacing for an unstable bradyarrhythmia, what is the next intervention? Administration of an epinephrine infusion is considered for symptomatic bradycardia. According to guidelines, by what time should a neurologic assessment and brain imaging be completed for a suspected stroke patient arriving at the emergency department at 7:10 p.m.? The stroke team should perform a neurologic assessment and obtain brain imaging by 7:30 p.m. What treatment is recommended for a stable patient with ventricular tachycardia, a pulse, and a corrected QT interval greater than 0.46 seconds? Synchronized cardioversion is the appropriate treatment choice. During a debriefing following a cardiac arrest, how can the resuscitation team indicate that they delivered high-quality CPR? "We provided 1 ventilation every 6 seconds and maintained chest compressions at a rate of 100 to 120 compressions per minute." A healthcare provider initiates ventilations to ensure adequate breathing and oxygenation. While ventilations are being performed, capnography is established to evaluate the adequacy of the ventilations. The healthcare provider determines that ventilations are adequate based on which end-tidal carbon dioxide (ETCO2) value? 35 to 45 mmHg End-tidal carbon dioxide values in the range of 35 to 45 mmHg confirm adequacy of ventilation. An ECG strip of a patient in the emergency department reveals the following rhythm. Which feature would the healthcare provider interpret as indicating atrial fibrillation? Absence of discrete P waves and presence of irregularly irregular QRS complexes. The two key features of atrial fibrillation on ECG are the absence of discrete P waves and the presence of irregularly irregular QRS
