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
... [Show More] action? - ANSStart chest compressions of at least 100 per min.
You are evaluating a 58-year-old man with chest pain. The blood pressure is 92/50 mm
Hg, the heart rate is 92/min, the nonlabored respiratory rate is 14 breaths/min, and the
pulse oximetry reading is 97%. What assessment step is most important now? - ANSObtaining a 12 lead ECG.
What is the preferred method of access for epi administration during cardiac arrest in
most pts? - ANS-Peripheral IV
An AED does not promptly analyze a rythm. What is your next step? - ANS-Begin chest
compressions.
You have completed 2 minutes of CPR. The ECG monitor displays the lead II rhythm
below, and the patient has no pulse. Another member of your team resumes chest
compressions, and an IV is in place. What management step is your next priority? -
ANS-Administer 1mg of epinephrine
During a pause in CPR, you see this lead II ECG rhythm on the monitor. The patient
has no pulse. What is the next action? - ANS-Resume compressions
What is a common but sometimes fatal mistake in cardiac arrest management? - ANSProlonged interruptions in chest compressions.
Which action is a componant of high-quality chest comressions? - ANS-Allowing
complete chest recoil
Which action increases the chance of successful conversion of ventricular fibrillation? -
ANS-Providing quality compressions immediately before a defibrillation attempt.
Which situation BEST describes pulseless electrical activity? - ANS-Sinus rythm without
a pulse
What is the BEST strategy for performing high-quality CPR on a patient with an
advanced airway in place? - ANS-Provide continuous chest compressions without
pauses and 10 ventilations per minute.
Three minutes after witnessing a cardiac arrest, one member of your team inserts an
endotracheal tube while another performs continuous chest compressions. During
subsequent ventilation, you notice the presence of a waveform on the capnographyscreen and a PETCO2 level of 8 mm Hg. What is the significance of this finding? - ANSChest compressions may not be effective. [Show Less]
