question; 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?
---ANS--
Start chest compressions of at least 100 per min.
question;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?
---ANS-- Obtaining a 12
lead ECG.
question;What is the preferred method of access for epi administration
during cardiac arrest in most pts?
,---ANS--
Peripheral IV
question;An AED does not promptly analyze a rythm. What is your next
step?
---ANS--
Begin chest compressions.
question;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
question;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
question;What is a common but sometimes fatal mistake in cardiac arrest
management?
,---ANS--
Prolonged interruptions in chest compressions.
question;Which action is a componant of high-quality chest comressions?
---ANS--
Allowing complete chest recoil
question;Which action increases the chance of successful conversion of
ventricular fibrillation?
---ANS--
Providing quality compressions immediately before a defibrillation
attempt.
question;Which situation BEST describes pulseless electrical activity?
---ANS--
Sinus rythm without a pulse
question;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.
question;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.
question;The use of quantitative capnography in intubated patients
---ANS--
allows for monitoring of CPR quality.
question;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.
