 Start with Flashcards 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?

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.

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

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.

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.

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.

Simple airway manuevers and assisted ventilations.
