Advanced Cardiovascular Life Support (ACLS) Exam Version A (50 Questions & Answers).Actual 2024 Exam Updated Graded A. You find an unresponsive patient who is not breathing. After activating the emergency response system, you determine that there is no pulse. What is your next action?--CORRECT ANSWER--D A. Open the airway with a head tilt–chin lift. B. Administer epinephrine at a dose of 1 mg/kg. C. Deliver 2 rescue breaths each over 1 second. D. Start chest compressions at a rate of at least 100/min. You are evaluating a 58-year-old man with chest pain. The blood pressure is 92/50 mm Hg, the heart rate is 92/min, the nonlabored respiratory rate is 14 breaths/min, and the pulse oximetry reading is 97%. What assessment step is most important now?--CORRECT ANSWER--D A. PETCO2 B. Chest x-ray C. Laboratory testing D. Obtaining a 12-lead ECG What is the preferred method of access for epinephrine administration during cardiac arrest in most patients?--CORRECT ANSWER--D A. Intraosseous B. Endotracheal C. Central intravenous D. Peripheral intravenous An activated AED does not promptly analyze the rhythm. What is your next action?--CORRECT ANSWER--A A. Begin chest compressions. B. Discontinue the resuscitation attempt. C. Check all AED connections and reanalyze. D. Rotate AED electrodes to an alternate position. You have completed 2 minutes of CPR. The ECG monitor displays the lead II rhythm below, and the patient has no pulse. Another member of your team resumes chest compressions, and an IV is in place. What management step is your next priority?--CORRECT ANSWER--C A. Give 0.5 mg of atropine. B. Insert an advanced airway. C. Administer 1 mg of epinephrine. D. Administer a dopamine infusion. During a pause in CPR, you see this lead II ECG rhythm on the monitor. The patient has no pulse. What is the next action?--CORRECT ANSWER--C A. Establish vascular access. B. Obtain the patient’s history. C. Resume chest compressions. D. Terminate the resuscitative effort. What is a common but sometimes fatal mistake in cardiac arrest management?--CORRECT ANSWER--D A. Failure to obtain vascular access B. Prolonged periods of no ventilations C. Failure to perform endotracheal intubation D. Prolonged interruptions in chest compressions Which action is a component of high-quality chest compressions?--CORRECT ANSWER--A A. Allowing complete chest recoil B. Chest compressions without ventilation C. 60 to 100 compressions per minute with a 15:2 ratio D. Uninterrupted compressions at a depth of 1½ inches Which action increases the chance of successful conversion of ventricular fibrillation?--CORRECT ANSWER--D A. Pausing chest compressions immediately after a defibrillation attempt B. Administering 4 quick ventilations immediately before a defibrillation attempt C. Using manual defibrillator paddles with light pressure against the chest D. Providing quality compressions immediately before a defibrillation attempt Which situation BEST describes pulseless electrical activity?--CORRECT ANSWER--B A. Asystole without a pulse B. Sinus rhythm without a pulse C. Torsades de pointes with a pulse D. Ventricular tachycardia with a pulse What is the BEST strategy for performing high-quality CPR on a patient with an advanced airway in place?--CORRECT ANSWER--D A. Provide compressions and ventilations with a 15:2 ratio. B. Provide compressions and ventilations with a 30:2 ratio. C. Provide a single ventilation every 6 seconds during the compression pause. D. Provide continuous chest compressions without pauses and 10 ventilations per minute. Three minutes after witnessing a cardiac arrest, one member of your team inserts an endotracheal tube while another performs continuous chest compressions. During subsequent ventilation, you notice the presence of a waveform on the capnography screen and a PETCO2 level of 8 mm Hg. What is the significance of this finding?--CORRECT ANSWER--A A. Chest compressions may not be effective. B. The endotracheal tube is no longer in the trachea. C. The patient meets the criteria for termination of efforts. D. The team is ventilating the patient too often (hyperventilation).
