AHA ACLS Written Test
67 terms by shaneeiYou 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?
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?
Obtaining a 12 lead ECG.
What is the preferred method of access for epi administration during cardiac arrest in most pts?
Peripheral IV
An AED does not promptly analyze a rythm. What is your next step?
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?
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?
Resume compressions
What is acommon but sometimes fatal mistake in cardiac arrest management?
Prolonged interruptions in chest compressions.
Which action is a componant of high-quality chest comressions?
Which action increases the chance of successful conversion of ventricular fibrillation?
Providing quality compressions immediately before a defibrillation attempt.
Which situation BEST describes PEA? Sinus rythm without a pulse
What is the best strategy for perfoming high-quality CPR on a pt.with an advanced airway in place?
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?
Chest compressions may not be effective.
The use of quantitative capnography in intubated pt's does what?
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?
Consider terminating resuscitive efforts after consulting medical control.
Which is a safe and effective practice within the defibrillation sequence?
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?
Begin chest compressions.
What is an advantage of using hands-free d-fib pads instead of d-fib paddles?
Hands-free allows for more rapid d-fib. What action is recommended to help
minimize interruptions in chest compressions during CPR?
Continue CPR while charging the defibrillator.
Which action is included in the BLS survey?
Early defibrillation Which drug and dose are recommended
for the management of a pt. in refractory V-FIB?
Amioderone 300mg
What is the appropriate intervalfor an interruption in chest compressions?
10 seconds or less Which of the following is a sign of
effective CPR?
PETCO2 = or > 10mm Hg What is the primary purpose of a medical
emergency team or rapid response team?
Identifying and treating early clinical deterioration.
Which action improves the quality of chest compressions delivered during resuscitave attemepts?
Shitch providers about every 2 min or every 5 compression cycles.

Choose an appropriate inidication to stop or withhold resuscitive efforts.
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?
Obtain a 12 lead ECG.
A pt. in respiratory failure becomes apneic but contineues to have a strong pulse. The heart rate is dropping paridly and now shows a sinus brady rate at 30/min. What intervention has the highest priority?
Simple airway manuevers and assisted ventilations.
