ACLS Written Exam (Q&A) 2024 You find an unresponsive pt. who is not breathing. After activating the emergency response system, you determine there is no pulse. What is your next action? ----- Start chest compressions of at least 100 per 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? ----- Obtaining a 12 lead ECG. What is the preferred method of access for epi administration during cardiac arrest in most pts? ----- Peripheral IV An AED does not promptly analyze a rythm. What is your next step? ----- Begin chest compressions. 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? ----- Administer 1mg of epinephrine 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? ----- Resume compressions What is a common but sometimes fatal mistake in cardiac arrest management? ----- Prolonged interruptions in chest compressions. Which action is a componant of high-quality chest comressions? ----- Allowing complete chest recoil Which action increases the chance of successful conversion of ventricular fibrillation? ----- Providing quality compressions immediately before a defibrillation attempt. Which situation BEST describes pulseless electrical activity? ----- Sinus rythm without a pulse What is the BEST strategy for performing high-quality CPR on a patient with an advanced airway in place? ----- 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? ----- Chest compressions may not be effective. The use of quantitative capnography in intubated patients ----- allows for monitoring of CPR quality. For the past 25 minutes, an EMS crew has attempted resuscitation of a patient who originally presented in ventricular fibrillation. After the first shock, the ECG screen displayed asystole, which has persisted despite 2 doses of epinephrine, a fluid bolus, and high-quality CPR. What is your next treatment? ----- Consider terminating resuscitive efforts after consulting medical control. Which is a safe and effective practice within the defibrillation sequence? ----- Be sure oxygen is not blowing over the patient's chest during the shock. During your assessment, your patient suddenly loses consciousness. After calling for help and determining that the patient is not breathing, you are unsure whether the patient has a pulse. What is your next action? ----- Begin chest compressions. What is an advantage of using hands-free defibrillation pads instead of defibrillation paddles? ----- Hands-free pads allow for a more rapid defibrillation. What action is recommended to help minimize interruptions in chest compressions during CPR? ----- Continue CPR while charging the defibrillator. Which action is included in the BLS survey? ----- Early defibrillation Which drug and dose are recommended for the management of a patient in refractory ventricular fibrillation? ----- Amioderone 300mg What is the appropriate interval for an interruption in chest compressions? ----- 10 seconds or less Which of the following is a sign of effective CPR? ----- PETCO2 ≥10 mm Hg What is the primary purpose of a medical emergency team (MET) or rapid response team (RRT)? ----- Identifying and treating early clinical deterioration. Which action improves the quality of chest compressions delivered during a resuscitation attempt? ----- Switch providers about every 2 minutes or every 5 compression cycles. What is the appropriate ventilation strategy for an adult in respiratory arrest with a pulse rate of 80/min? ----- 1 breath every 5-6 seconds A patient presents to the emergency department with new onset of dizziness and fatigue. On examination, the patient's heart rate is 35/min, the blood pressure is 70/50 mm Hg, the respiratory rate is 22 breaths/min, and the oxygen saturation is 95%.

What should be done to minimize interruptions in chest compressions during CPR? ----- Continue CPR while the defibrillator is charging. Which condition is an indication to stop or withhold resuscitative efforts? ----- Safety threat to providers After verifying the absence of a pulse, you initiate CPR with adequate bag-mask ventilation. The patient's lead II ECG appears below. What is your next action? ----- IV or IO access After verifying unresponsiveness and abnormal breathing, you activate the emergency response team. What is your next action? ----- Check for a pulse. What is the recommendation on the use of cricoid pressure to prevent aspiration during cardiac arrest? ----- Not recommended for routine use What survival advantages does CPR provide to a patient in ventricular fibrillation? ----- Produces a small amount of blood flow to the heart What is the recommended compression rate for performing CPR? ----- At least 100 per minute EMS personnel arrive to find a patient in cardiac arrest. Bystanders are performing CPR. After attaching a cardiac monitor, the responder observes the following rhythm strip. What is the most important early intervention? ----- defibrillation A patient remains in ventricular fibrillation despite 1 shock and 2 minutes of continuous CPR. The next intervention is to ----- administer a second shock. What is the recommended next step after a defibrillation attempt? ----- Begin CPR, starting with chest compressions. Which of the following is the recommended first choice for establishing intravenous access during the attempted resuscitation of a patient in cardiac arrest? ----- Antecubital vein Which finding is a sign of ineffective CPR? ----- PETCO2 <10 mm Hg How often should the team leader switch chest compressors during a resuscitation attempt? ----- . Every 2 minutes IV/IO drug administration during CPR should be ----- given rapidly during compressions What is the recommended first intravenous dose of amiodarone for a patient with refractory ventricular fibrillation? ----- 300 mg A team leader orders 1 mg of epinephrine, and a team member verbally acknowledges when the medication is administered. What element of effective resuscitation team dynamics does this represent? ----- Closed-loop communication How long should it take to perform a pulse check during the BLS Survey? ----- 5 to 10 seconds Your rescue team arrives to find a 59-year-old man lying on the kitchen floor. You determine that he is unresponsive and notice that he is taking agonal breaths. What is the next step in your assessment and management of this patient? ----- Check the patient's pulse.
