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? -Correct
Answer ✔Start 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? -Correct
Answer ✔Obtaining a 12 lead ECG.
What is the preferred method of access for epi administration during cardiac arrest in
most pts? -Correct Answer ✔Peripheral IV
An AED does not promptly analyze a rythm. What is your next step? -Correct Answer
✔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? -
Correct Answer ✔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? -Correct Answer ✔Resume compressions
What is a common but sometimes fatal mistake in cardiac arrest management? -Correct
Answer ✔Prolonged interruptions in chest compressions.
Which action is a componant of high-quality chest comressions? -Correct Answer
✔Allowing complete chest recoil
Which action increases the chance of successful conversion of ventricular fibrillation? -
Correct Answer ✔Providing quality compressions immediately before a defibrillation
attempt.
Which situation BEST describes pulseless electrical activity? -Correct Answer ✔Sinus
rythm without a pulse
What is the BEST strategy for performing high-quality CPR on a patient with an
advanced airway in place? -Correct Answer ✔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? -
Correct Answer ✔Chest compressions may not be effective.
The use of quantitative capnography in intubated patients -Correct Answer ✔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? -Correct Answer ✔Consider
terminating resuscitive efforts after consulting medical control.
Which is a safe and effective practice within the defibrillation sequence? -Correct
Answer ✔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? -Correct Answer ✔Begin chest
compressions.
What is an advantage of using hands-free defibrillation pads instead of defibrillation
paddles? -Correct Answer ✔Hands-free pads allow for a more rapid defibrillation.
What action is recommended to help minimize interruptions in chest compressions
during CPR? -Correct Answer ✔Continue CPR while charging the defibrillator.
Which action is included in the BLS survey? -Correct Answer ✔Early defibrillation
Which drug and dose are recommended for the management of a patient in refractory
ventricular fibrillation? -Correct Answer ✔Amioderone 300mg
What is the appropriate interval for an interruption in chest compressions? -Correct
Answer ✔10 seconds or less
Which of the following is a sign of effective CPR? -Correct Answer ✔PETCO2 ≥10 mm
Hg
What is the primary purpose of a medical emergency team (MET) or rapid response
team (RRT)? -Correct Answer ✔Identifying and treating early clinical deterioration.
