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? - ANS Obtaining 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? - ANS
Prolonged 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 capnography screen and a PETCO2
level of 8 mm Hg. What is the significance of this finding? - ANS Chest compressions may
not be effective.
The use of quantitative capnography in intubated patients - ANS allows for monitoring of
CPR quality.
For the past 25 minutes, an EMS crew has attempted resuscitation of a patient who originally
presented in ventricular fibrillation. After the first shock, the ECG screen displayed asystole,
which has persisted despite 2 doses of epinephrine, a fluid bolus, and high-quality CPR. What is
your next treatment? - ANS Consider terminating resuscitive efforts after consulting medical
control.
Which is a safe and effective practice within the defibrillation sequence? - ANS Be sure
oxygen is not blowing over the patient's chest during the shock.
During your assessment, your patient suddenly loses consciousness. After calling for help and
determining that the patient is not breathing, you are unsure whether the patient has a pulse.
What is your next action? - ANS Begin chest compressions.
What is an advantage of using hands-free defibrillation pads instead of defibrillation paddles? -
ANS Hands-free pads allow for a more rapid defibrillation.
