ACLS 2022 QUIZ |50 QUESTIONS AND ANSWERS

given rapidly during compressions IV/IO drug administration during CPR should be Potential oxygen toxicity What is the danger of routinely administering high concentrations of oxygen during post-cardiac arrest period for patients who achieve ROSC? NOT recommended for routine use Recommendation on the use of cricoid pressure to prevent aspiration during cardiac arrest Performing a head tilt chin lift maneuver Family members found a 45 year old woman unresponsive in bed. Patient is unconscious and in respiratory arrest. What is the recommended initial airway management technique? Check for a pulse After verifying unresponsiveness and abnormal breathing, you activate emergency response team. What is your next action? Unstable supraventricular tachycardia A responder is caring for a patient with a history of congestive heart failure. Patient is experiencing shortness of breath, a BP of 68/50 mmHg, and HR of 190/min. Patient's lead II ECG is displayed above (shows unstable SVT). Which of the following best describes this patient? 300 mg Recommended 1st IV dose of amiodarone for a patient with refractory ventricular fibrillation? Administer a second shock Patient remains in ventricular fibrillation despite 1 shock and 2 minutes of continuous CPR. Next intervention is to Administer 2 to 4 mg of morphine by slow IV bolus 49 year old man has retrosternal chest pain radiating into the left arm. Patient is diaphoretic, with associated shortness of breath. BP is 130/88 mmHg, HR is 110/min, RR is 22 breaths/min, and pulse oximetry is 95%. Patient's 12 lead ECG shows ST segment elevation in the anterior leads. First responders administered 160 mg aspirin, and there is a patent peripheral IV. Pain described as a 8/10 and unrelieved after 3 doses of nitroglycerin. What is the next action? At least 100/min What is the appropriate rate of chest compressions for an adult in cardiac arrest? Defibrillation 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? Obtaining a 12 lead ECG You are evaluating a 58-year-old man with chest pain. BP is 92/50 mmHg, HR is 92/min, nonlabored RR is 14 breaths/min, and the pulse oximetry reading is 97%. What assessment step is most important now? Administration of IV or IO fluid bolus What is the recommended initial intervention for managing hypotension in the immediate period after return of spontaneous circulation (ROSC)? Divert the patient to a hospital 15 minutes away with CT capabilities You are receiving a radio report from an EMS team en route with a patient who may be having an acute stroke. The hospital CT scanner is not working at this time. What should you do in this situation? Closed-loop communication 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? Transport the patient to a facility capable of performing PCI Which is an appropriate and important intervention to perform for a patient who achieves ROSC during an out-of-hospital resuscitation? Epinephrine Which treatment or medication is appropriate for the treatment of a patient in asystole? Administer the shock immediately and continue as directed by the AED An AED advises a shock for a pulseless patient lying in snow. What is the next action? Start chest compressions at a rate of at least 100/min A patient with pulseless ventricular tachycardia is defibrillated. What is the next action? IV or IO access 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? Right ventricular infarction and dysfunction Which is a contraindication to nitroglycerin administration in the management of acute coronary syndromes? 32°C to 34°C What is the recommended target temperature range for achieving therapeutic hypothermia after cardiac arrest? PETCO2 < 10 mm Hg Which finding is a sign of ineffective CPR? Seeking expert consultation A 56-year-old man reports that he has palpitations but not chest pain or difficulty breathing. BP is 132/68 mmHg, pulse is 130/min and regular, RR is 12 breaths/min, and pulse oximetry reading is 95%. The lead II ECG displays a wide-complex tachycardia. What is the next action after establishing an IV and obtaining a 12-lead ECG? Check the patient's pulse 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? 2 inches What is the minimum depth of chest compressions for an adult in cardiac arrest? Conduct a problem-focused history and physical examination An 80-year-old woman presents to the emergency department with dizziness. She now states she is asymptomatic after walking around. Her BP is 102/72 mmHg. She is alert and oriented. Her lead II ECG is below. After you start an IV, what is the next action? 5 to 10 seconds How long should it take to perform a pulse check during the BLS Survey? 160 to 325 mg What is the recommended oral dose of aspirin for patients suspected of having one of the acute coronary syndromes? Every 2 minutes How often should the team leader switch chest compressors during a resuscitation attempt? 10 to 12 breaths per minute What is the recommended assisted ventilation rate for patients in respiratory arrest with a perfusing rhythm?
