ACLS Megacode 5 In-HospitalHurry, don’t let time run out!Sorry, time is up!0 Hours 0 mins 0 secsStep 1 of 1010%You are a healthcare provider working in the cardiac care unit of your hospital. A 51-year-old female who underwent percutaneous coronary intervention 4 hrs ago is reporting severe nausea and light-headedness. A rapid initial assessment reveals the following:Vital signsPulse rate: 160/minBlood pressure: 127/80Respiratory rate: 22/minTemperature: 37.2 °CPhysiological systemsIntegumentary: Warm, dryCardiovascular: Strong peripheral pulses bilaterallyRespiratory: CTA bilaterallyNeurological: Alert1. You ensure adequate IV access and perform a 12-lead ECG, which reveals narrow-complex supraventricular tachycardia at 160/min. You determine the arrythmia to be stable given the absence of hypotension, changes in consciousness, shock, or chest pain. What are your initial actions?* Perform immediate synchronized cardioversion Prepare for the placement of an advanced airway Attempt vagal maneuvers Administer adenosine 6.0 mg IVPVagal maneuvers are attempted with no change in condition. A rhythm check reveals unchanged narrow complex supraventricular tachycardia.2. What are your next actions?* Administer adenosine 12.0 mg IVP Administer adenosine 6.0 mg IVP Continue attempting vagal maneuvers until conversion to sinus rhythm occurs Administer amiodarone 150 mg IV infusion over 8 min and repeat as neededAdenosine 6.0 mg IVP is administered with no change in condition. A second dose of adenosine at 12.0 mg IVP is given, following which the patient develops severe central chest pain and. BP is unobtainable and HR increases to 225/min. Radial pulses become faint and weak bilaterally. The patient is no longer responding to verbal commands.3. What are your next actions?* Administer a third dose of adenosine 12.0 mg IVP The patient is now unstable; perform immediate synchronized cardioversion Deliver a single unsynchronized shock of 120 J Place an advanced airway and begin assisted ventilationImmediate synchronized cardioversion is performed with no change in condition, and the patient continues to deteriorate. The patient loses consciousness and peripheral pulses are no longer palpable bilaterally. A rhythm check reveals a conversion from narrow complex supraventricular tachycardia to ventricular tachycardia.4. What are your next actions?* Place an advanced airway and begin assisted ventilation Administer epinephrine 1.0 mg IVP Deliver a single unsynchronized shock of 120 J Start CPR (five cycles)A single unsynchronized shock of 120 J is delivered, and CPR is started. Following five cycles of CPR, a rhythm check reveals unchanged ventricular tachycardia. A single unsynchronized shock of 200 J is delivered, and CPR is resumed for another five cycles.5. What are your next actions?* Pharmacological intervention is not indicated at this time Administer dopamine 20 mcg/kg/min IV fluid bolus Administer epinephrine 0.5 mg IVP during the last cycle of CPR Administer epinephrine 1.0 mg IVP during the first cycle of CPRFive cycles of CPR are performed, and you have administered epinephrine 1.0 mg IVP with no change in condition. You prepare to deliver a third shock.6. Assuming a biphasic defibrillator is being used, what setting will you use for the third shock?* 220 J 300 J 120 J 180 JA single unsynchronized shock of 300 J is given, and CPR is resumed for another five cycles. You have decided to administer amiodarone during the first cycle of CPR.7. What dose should you be administering?* 400 mg IV infusion over 45 min 150 mg IVP 200 mg IVP 300 mg IVP followed by a second dose of 150 mg IVP if no effect is notedAmiodarone 300 mg IVP is administered, and CPR is resumed for another five cycles. Following five cycles of CPR, a rhythm check reveals conversion from ventricular tachycardia to sinus rhythm. Return of spontaneous circulation is noted. During the post-cardiac arrest phase, a short run of ventricular tachycardia is observed, and an amiodarone infusion is started as part of the post-resuscitation care.8. What is the maximum cumulative dose of amiodarone that
