 To properly ventilate a patient with a perfusing rhythm, how often do you squeeze the bag? Once every 5 to 6 seconds.  in addition to clinical assessment, which is the most reliable method to confirm and monitor correct placement of an endotracheal tube? Continuous waveform capnography  EMS providers are treating a patient with suspected stroke. According to the Adult Suspected Stroke Algorithm, which critical action performed by the EMS team will expedite this patient's care on arrival and reduce the time to treatment? Alert the hospital.  Your rescue team arrives to find a 59-year-old man lying on the kitchen floor. You determine that he is unresponsive. Which is the next step in your assessment and management of this patient? Check the patient's breathing and pulse.  For STEMI patient, which best describes the recommended maximum goal time for emergency department door-to-balloon inflation time for percutaneous coronary intervention? 90 minutes. A patient in respiratory distress and with a blood pressure of 70/50 mmHg presents with the lead IIECG rhythm shown here. Which is the appropriate treatment? Performing synchronized cardioversion.       Three minutes into a cardiac resuscitation attempt, one member of your team inserts an endotracheal tube while another performs chest compressions. Capnography shows a persistent waveform and a PETCO2 of 8 mmHg. Which is the significance of this finding? Chest compressions may not be effective. You are performing chest compressions during an adult resuscitation attempt. Which rate should you use to perform the compressions? 100 to 120/min. A patient is being resuscitated in a very noisy environment. A team member thinks he heard an order for 500 mg of amiodarone IV. Which is the best response? I have an order to give 500 mg of amiodarone IV. A patient has a witnessed loss of consciousness. The lead II ECG reveals this rhythm. Which is the appropriate treatment? Defibrillation You have completed 2 minutes of CPR. The ECG monitor displays the lead II rhythm shown here, and the patient has no pulse. Another member of your team resumes chest compressions, and an IV is in place. What do you do next? Give epinephrine 1 mg IV.         Based on this patient's initial presentation, which condition do you suspect led to the cardiac arrest? Acute Coronary Syndrome. Despite 2 Defibrillation attempts, the patient remains in ventricular fibrillation. Which drug and dose should you administer first to this patient? Epinephrine 1 mg. Despite the drug provided above and continued CPR, the patient remains in ventricular fibrillation. Which other drug should be administered next? Amiodarone 300 mg. The patient has return of spontaneous circulation and is not able to follow commands. Which immediate post-cardiac arrest care intervention do you choose for this patient? Initiate targeted temperature management. Which would you have done first if the patient had not gone into ventricular fibrillation? Performed synchronized cardioversion. Based on this patient's initial assessment, which adult ACLS algorithm should you follow? Tachycardia. After your initial assessment of this patient, which intervention should be performed next? synchronized cardioversion If the patient became apneic and pulseless but the rhythm remained the same, which would take the highest priority? perform defibrillation
