AHA ACLS Written Test (A+ graded 100% verified latest update)

AHA ACLS Written Test (A+ graded 100% verified latest update) 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? Correct answer: Start chest compressions of at least 100 per min. 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? Correct answer: Obtaining a 12 lead ECG. What is the preferred method of access for epi administration during cardiac arrest in most pts? Correct answer: Peripheral IV An AED does not promptly analyze a rythm. What is your next step? Correct answer: Begin chest compressions. 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? Correct answer: Administer 1mg of epinepherine During a pause in CPR, you see a narrow complex rythm on the monitor. The pt. has no pulse. What is the next action? Correct answer: Resume compressions What is acommon but sometimes fatal mistake in cardiac arrest management? Correct answer: Prolonged interruptions in chest compressions. Which action is a componant of high-quality chest comressions? Correct answer: Allowing complete chest recoil Which action increases the chance of successful conversion of ventricular fibrillation? Correct answer: Providing quality compressions immediately before a defibrillation attempt. Which situation BEST describes PEA? Correct answer: Sinus rythm without a pulse What is the best strategy for perfoming high-quality CPR on a an advanced airway in place? Correct answer: Provide continuous chest compressionswithout pauses and 10 ventilations per minute. 3 min after witnessing a cardiac arrest, one memeber of your team inserts an ET tube while another performs continuous chest comressions. During subsequent bentilation, you notice the presence of a wavefom on the capnogrophy screen and a PETCO2 of 8 mm Hg. What is the significance of this finding? Correct answer: Chest compressions may not be effective. The use of quantitative capnography in intubated pt's does what? Correct answer: Allowsfor monitoring CPR quality 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? Correct answer: Consider terminating resuscitive efforts after consulting medical control. Which is a safe and effective practice within the defibrillation sequence? Correct answer: Be sure O2 is NOT blowing over the pt's chest during shock. 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? Correct answer: Begin chest compressions. What is an advantage of using hands-free d-fib pads instead of d-fib paddles? Correct answer: Hands-free allows for more rapid d-fib. What action is recommended to help minimize interruptions in chest compressions during CPR? Correct answer: Continue CPR while charging the defibrillator. Which action is included in the BLS survey? Correct answer: Early defibrillation Which drug and dose are recommended for the management of a pt. in refractory V-FIB? Correct answer: Amioderone 300mg What is the appropriate intervalfor an interruption in chest compressions? Correct answer: 10 seconds or less Which of the following is a sign of effective CPR? Correct answer: PETCO2 = or > 10mm Hg What is the primary purpose of a medical emergency team or rapid response team? Correct answer: Identifying and treating early clinical deterioration. Which action improves the quality of chest compressions delivered during resuscitave attemepts? Correct answer: Shitch providers about every 2 min or every 5 compression cycles. What is the appropriate ventilation strategy for an adult in respiratory arrest with a pulse of 80 beats/min? Correct answer: 1 breath every 5-6 seconds 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? Correct answer: Atropine 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? Correct answer: 2-10mcg/kg/min A pt. has an onset of dizziness. The pt.s heart rate is 180, BP is 110/70, resp. rate is 18, O2 sat is 98%. This is a reg narrow complex tach rythm. What is the next intervention? Correct answer: Vagal manuever. A monitored pt. in the ICU developed a suddent onset of narrow complex tach at a rate of 220/min. The pt's BP is 128/58, the PETCO2 is 38mm Hg, and the O2 sat is 98%. There is an EJ established for vascular access. The pt. denies taking any vasodialators. A 12 lead shows no ischemia or infarction. Vagal manuevers are ineffective. What is the next intervention? Correct answer: Adenosine 12mg IV 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? Correct answer: Divert the pt. to a hospital 15 min away with CT capabilities. Choose an appropriate inidication to stop or withhold resuscitive efforts. Correct answer: Evidence of rigor mortis. A 49 y/ofmaile arrives in the ER with persistant epigastric pain. She has been taking antacids PO for the past 6 hours because she she had heartburn. BP is 118/72, heart rate is 92/min, resp. rate is 14 non-labored and O2 sat is 96%. What is the most appropriate next action? Correct answer: Obtain a 12 lead ECG.
