Shock-refractory monomorphic ventricular tachycardia Ventricular tachycardia associated with a normal QT interval Shock-refractory ventricular fibrillation Pulseless ventricular tachycardia-associated torsades de pointes - CORRECT ANSWER Pulseless ventricular tachycardia-associated torsades de pointes You arrive on the scene with the code team. High-quality CPR is in progress. An AED has previously advised "no shock indicated." A rhythm check now finds asystole. After resuming high-quality compressions, which action do you take next? Perform endotracheal intubation Call for a pulse check Insert a laryngeal airway Establish IV or IO access - CORRECT ANSWER Establish IV or IO access A 35-year-old woman has palpitations, light-headedness, and a stable tachycardia. The monitor shows a regular narrow-complex QRS at a rate of 180/min. Vagal maneuvers have not been effective in terminating the rhythm. An IV has been established. Which drug should be administered? Epinephrine 2 to 10 mcg/kg per minute Lidocaine 1 mg/kg Atropine 0.5 mg Adenosine 6 mg - CORRECT ANSWER Adenosine 6 mg A 62-year-old man suddenly experienced difficulty speaking and left-sided weakness. He meets initial criteria for fibrinolytic therapy, and a CT scan of the brain is ordered. Which best describes the guidelines for antiplatelet and fibrinolytic therapy? Give aspirin 120 mg and clopidogrel 75 mg orally Give aspirin 162 to 325 mg to be chewed immediately Give heparin if the CT scan is negative for hemorrhage Hold aspirin for at least 24 hours if rtPA is administered - CORRECT ANSWER Hold aspirin for at least 24 hours if rtPA is administered How often should you switch chest compressors to avoid fatigue? About every 2 minutes About every 4 minutes About every 5 minutes About every 3 minutes - CORRECT ANSWER About every 2 minutes Your patient is a 56-year-old woman with a history of type 2 diabetes who reports feeling dizzy. She is pale and diaphoretic. Her blood pressure is 80/60 mm Hg. The cardiac monitor documents the rhythm shown here. She is receiving oxygen at 4 L/min by nasal cannula, and an IV has been established. What do you administer next?

On the next rhythm check, you see the rhythm shown here. Team members tell you that the patient was well but reported chest discomfort and then collapsed. She has no pulse or respirations. Bag-mask ventilations are producing visible chest rise, and IO access has been established. Which intervention would be your next action? Intubation and administration of 100% oxygen Epinephrine 1 mg Dopamine at 10 to 20 mcg/kg per minute Atropine 1 mg - CORRECT ANSWER Epinephrine 1 mg After initiation of CPR and 1 shock for ventricular fibrillation, this rhythm is present on the next rhythm check. A second shock is given, and chest compressions are resumed immediately. An IV is in place, and no drugs have been given. Bag-mask ventilations are producing visible chest rise. What is your next intervention? Give epinephrine 1 mg IV/IO Administer 3 sequential (stacked) shocks at 320 J (monophasic defibrillator) Intubate and administer 100% oxygen Give amiodarone 300 mg IV/IO - CORRECT ANSWER Give epinephrine 1 mg IV/IO A 35-year-old woman presents with a chief complaint of palpitations.
