3 min after witnessing a cardiac arrest, one memeber of your team inserts an ET tube while another performs continuous chest comressions.

A pt. presents to the ER with a new onset of dizziness and fatugue. Onexamination, the pt's heart rate is 35 beats/min, BP is 70/50, resp. rate is 22 per min, O2 sat is 95%. What is the appropriate 1st medication? - ANSAtropine 0.5mg A pt. presents to the ER with dizziness and SOB with a sinus brady of 40/min. The initial atropine dose was ineffective and your monitor does not provide TCP. What is the appropriate dose of Dopamine for this pt? - ANS2-10mcg/kg/min

An AED does not promptly analyze a rythm. What is your next step? - ANSBegin chest compressions. Choose an appropriate inidication to stop or withhold resuscitive efforts. - ANSEvidence of rigor mortis. During a pause in CPR, you see a narrow complex rythm on the monitor. The pt. has no pulse. What is the next action? - ANSResume compressions During your assessment, your pt suddenly loses consciousness. After calling for help and determining that the pt. is not breathing, you are unsure whether the pt. has a pulse. What is your next action? - ANSBegin chest compressions. For the past 25 min, EMS crews have attemptedresuscitation of a pt who originally presented with V-FIB. After the 1st shock, the ECG screen displayed asystole which has persisted despite 2 doses of epi, a fluid bolus, and high quality CPR. What is your next treatment? - ANSConsider terminating resuscitive efforts after consulting medical control. The use of quantitative capnography in intubated pt's does what? - ANSAllowsfor monitoring CPR quality

What action is recommended to help minimize interruptions in chest compressions during CPR? - ANSContinue CPR while charging the defibrillator. What is acommon but sometimes fatal mistake in cardiac arrest management? - ANSProlonged interruptions in chest compressions. What is an advantage of using hands-free d-fib pads instead of d-fib paddles? - ANSHands-free allows for more rapid d-fib. What is the 1st treatment priority for a pt. who achieves ROSC? - ANSOptimizing ventilation and oxygenation. What is the appropriate intervalfor an interruption in chest compressions? - ANS10 seconds or less What is the appropriate procedure for ET suctioning after the catheter is selected? - ANSSuction during withdrawl, but not for longer than 10 seconds. What is the appropriate ventilation strategy for an adult in respiratory arrest with a pulse of 80 beats/min? - ANS1 breath every 5-6 seconds What is the best strategy for perfoming high-quality CPR on a pt.with an advanced airway in place? - ANSProvide continuous chest compressionswithout pauses and 10 ventilations per minute.

What is the initial priority for an unconscious pt. with any tachycardia on the monitor? - ANSDetermine if a pulse is present. What is the minimum systolic BP one should attempt to achieve with fluid, Inotropic, or vasopressor administration in a hypotensive post-cardiac arrest who achieves ROSC? - ANS90mm Hg What is the most reliable method of confirming and montioring correct placement of an ET tube? - ANSContinuous waveform capnography What is the potential danger to using ties that pass circumfrentially around the pt's neck when securing an advanced airway? - ANSObstruction of veneous return from the brain What is the preferred method of access for epi administration during cardiac arrest in most pts? - ANSPeripheral IV What is the primary purpose of a medical emergency team or rapid response team? - ANSIdentifying and treating early clinical deterioration. What is the proper ventilation rate for a pt. in cardiac arrest who has an advanced airway in place? - ANS8-10 breaths per minute What is the recommended dose for adenosine for pt's in refractory, but stable narrow complex tachycardia? - ANS12mg

What is the recommended IV fluid (NS or LR) bolus dose for a pt. who achieves ROSC but is hypotensive during the post-cardiac arrest period? - ANS1 to 2 Liters What is the usual post-cardiac arrest target range for PETCO2 who achieves return of spontaneous circulation (ROSC)? - ANS35-40mm Hg Which action improves the quality of chest compressions delivered during resuscitave attemepts? - ANSShitch providers about every 2 min or every 5 compression cycles. Which action increases the chance of successful conversion of ventricular fibrillation? - ANSProviding quality compressions immediately before a defibrillation attempt. Which action is a componant of high-quality chest comressions? - ANSAllowing complete chest recoil Which action is included in the BLS survey? - ANSEarly defibrillation Which conditionis a contraindication to theraputic hypothermia during the post-cardiac arrest period for pt's who achieve return of spontaneous circulation (ROSC)? - ANSResponding to verbal commands

Which drug and dose are recommended for the management of a pt. in refractory V-FIB? - ANSAmioderone 300mg Which is a safe and effective practice within the defibrillation sequence? - ANSBe sure O2 is NOT blowing over the pt's chest during shock. Which of the following is a sign of effective CPR? - ANSPETCO2 = or > 10mm Hg Which rythm requires synchronized cardioversion? - ANSUnstable SVT Which situation BEST describes PEA? - ANSSinus rythm without a pulse While treating a stable pt for dizziness, a BP of 68/30, cool and clammy, you see a brady rythm on the ECG. How do you treat this? - ANSAtropine 0.5mg You are evaluating a 48 y/o male with crushing sub-sternal pain. He is cool, pale, diaphretic, and slow to respond to your questions. BP is 58/32, pulse is 190/min, resp rate is 18, and you are unable to obtain an 02 sat due to no radial pulse. The ECG shows a wide complex tach rythm. What intervention should be next? - ANSSyncronized cardioversion. 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? - ANSObtaining a 12 lead ECG. You are transporting a pt. with a positive stroke assessment. BP is 138, pulse is 80/min, resp rate is 12/min, 02 sat is 95% room air. Glucose levels are normal and the ECG shows a sinus rythm. What is next. - ANSHead CT scan You find an unresponsive pt. who is not breathing. After activating the emergency response system, you determine there is no pulse. What is your next action? - ANSStart chest compressions of at least 100 per min. You have completed 2 min of CPR. The ECG monitor displays the lead below (PEA) and the pt. has no pulse. You partner resumes chest compressions and an IV is in place. What management step is your next priority? - ANSAdminister 1mg of epinepherine You receiving a radio report from an EMS team enroute with a pt. who may be having a stroke. The hospital CT scanner is broken. What should you do? - ANSDivert the pt. to a hospital 15 min away with CT capabilities.
