During post-cardiac arrest care, which is the recommended duration of targeted temperature management after reaching the correct temperature range? At least 24 hours You are caring for a patient with a suspected stroke whose symptoms started 2 hours ago. The CT scan was normal, with no signs of hemorrhage. The patient does not have any contraindications to fibrinolytic therapy. Which treatment approach is best for this patient? Start fibrinolytic therapy as soon as possible Which is one way to minimize interruptions in chest compressions during CPR? Continue CPR while the defibrillator charges Which best describes the length of time it should take to perform a pulse check during the BLS Assessment? 5 to 10 seconds You are evaluating a 58 year old man with chest pain. The BP is 92/50 and a heart rate of 92/min, non-labored respiratory rate is 14 breaths/min and the pulse O2 is 97%. What assessment step is most important now? Obtaining a 12-lead ECG A 45yo man had coronary artery stents placed 2 days ago. Today,he is in severe distress and reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mmHg, respiratory rate is 28 breaths/min, and O2 sat is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Based on this patient's initial presentation, which condition do you suspect led to the cardiac arrest? Acute coronary syndrome A 45yo man had coronary artery stents placed 2 days ago. Today,he is in severe distress and reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mmHg, respiratory rate is 28 breaths/min, and O2 sat is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. In addition to defibrillation, which intervention should be performed immediately? Chest compressions A 45yo man had coronary artery stents placed 2 days ago. Today,he is in severe distress and reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mmHg, respiratory rate is 28 breaths/min, and O2 sat is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Despite 2 defibrillation attempts, the patient remains in vfib. which drug and dose should you administer first to this patient? Epinephrine 1 mg A 45yo man had coronary artery stents placed 2 days ago. Today,he is in severe distress and reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mmHg, respiratory rate is 28 breaths/min, and O2 sat is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Despite the initial drug provided after two shocks and continued CPR, the patient remains in ventricular fibrillation. Which other drug should be administered next? Amiodarone 300 mg A 45yo man had coronary artery stents placed 2 days ago. Today,he is in severe distress and reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mmHg, respiratory rate is 28 breaths/min, and O2 sat is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. 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 A 45yo man had coronary artery stents placed 2 days ago. Today,he is in severe distress and reporting "crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is very weak, blood pressure is 64/40 mmHg, respiratory rate is 28 breaths/min, and O2 sat is 89% on room air. When applied, the cardiac monitor initially showed ventricular tachycardia, which then quickly changed to ventricular fibrillation. Which would you have done first if the patient had not gone into vfib? Performed synchronized cardioversion As the team leader, when do you tell the chest compressors to switch? About every 2 minutes This rhythm Monomorphic ventricular tachycardia Your patient is in cardiac arrest and has been intubated. To assess CPR quality, which should you do? Monitor the patient's PETCO2 Which of these tests should be performed for a patient with suspected stroke within 25 minutes of hospital arrival? Noncontrast CT scan of the head A patient in respiratory distress and with a blood pressure of 70/50 mm Hg presents with the following lead II ECG rhythm: What is the appropriate next intervention? Performing synchronized cardioversion Three minutes into a cardiac arrest 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 mm Hg. Which is the significance of this finding? A. Chest compressions may not be effective B. The endotracheal tube is in the esophagus C. The patient meets the criteria for termination of efforts D. The team is ventilating the patient too often (hyperventilation) A. Chest compressions may not be effective For STEMI patients, which best describes the recommended maximum goal time for emergency department door-to-balloon inflation time for percutaneous coronary intervention? A. 180 minutes B. 150 minutes C. 120 minutes D. 90 minutes D. 90 minutes Which facility is the most appropriate EMS destination for a patient with sudden cardiac arrest who achieved return of spontaneous circulation in the field? Coronary reperfusion-capable medical center Which type of AV block shown Second-degree type II A 68 yo woman presents with lightheadedness, nausea, and chest discomfort. Your assessment finds her awake and responsive but ill-appearing, pale, and grossly diaphoretic. Her radial pulse is weak, thready, and fast. You are unable to obtain a blood pressure. She has no obvious dependent edema, and her neck veins are flat. Her lung sounds are equal, with moderate rales present bilaterally. The cardiac monitor shows the rhythm shown. Based on this patient's initial assessment, which adult ACLS algorithm should you follow? Tachycardia
