What is the proper ventilation rate for a pt. in cardiac arrest who has an advanced airway in place? -
CORRECT ANSWERS-8-10 breaths per minute
A 62 y/o male pt. in the ER says his heart is beating fast. No chest pain or SOB. BP is 142/98, pulse rate is
200/min, reps rate is 14/min, O2 sats are 95 at room air. What should be the next evaluation? -
CORRECT ANSWERS-Obtain a 12 lead ECG.
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? - CORRECT ANSWERS-Syncronized cardioversion.
What is the initial priority for an unconscious pt. with any tachycardia on the monitor? - CORRECT
ANSWERS-Determine if a pulse is present.
Which rythm requires synchronized cardioversion? - CORRECT ANSWERS-Unstable SVT
What is the recommended dose for adenosine for pt's in refractory, but stable narrow complex
tachycardia? - CORRECT ANSWERS-12mg
What is the preferred method of access for epi administration during cardiac arrest in most pts? -
CORRECT ANSWERS-Peripheral IV
An AED does not promptly analyze a rythm. What is your next step? - CORRECT ANSWERS-
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 ANSWERS-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 ANSWERS-Resume compressions
What is acommon but sometimes fatal mistake in cardiac arrest management? - CORRECT
ANSWERS-Prolonged interruptions in chest compressions.
Which action is a componant of high-quality chest comressions? - CORRECT ANSWERS-
Allowing complete chest recoil
Which action increases the chance of successful conversion of ventricular fibrillation? - CORRECT
ANSWERS-Providing quality compressions immediately before a defibrillation attempt.
Which situation BEST describes PEA? - CORRECT ANSWERS-Sinus rythm without a pulse
What is the best strategy for perfoming high-quality CPR on a pt.with an advanced airway in place? -
CORRECT ANSWERS-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 ANSWERS-Chest compressions may not be effective.
The use of quantitative capnography in intubated pt's does what? - CORRECT ANSWERS-
Allowsfor monitoring CPR quality
For the past 25 min, EMS crews have attempted resuscitation 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 ANSWERS-Consider
terminating resuscitive efforts after consulting medical control.
