ACLS Written Exam Questions and Answers

ACLS Written Exam Questions and Answers 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 is the appropriate first medication? Atropine 0.5mg A patient with dizziness and shortness of breath with a sinus bradycardia of 40/min. The initial atropine dose was ineffective, and your monitor/defibrillator is not equipped with a transcutaneous pacemaker. What is the appropriate dose of dopamine for this patient? 2 to 10 mcg/kg per minute
