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.
You are evaluating a 48-year-old man with crushing substernal chest pain. The patient is pale,
diaphoretic, cool to the touch, and slow to respond to your questions. The blood pressure is 58/32 mm
Hg, the heart rate is 190/min, the respiratory rate is 18 breaths/min, and the pulse oximeter is unable to
obtain a reading because there is no radial pulse. The lead II ECG displays a regular wide-complex
tachycardia. What intervention should you perform next? - correct answer -Synchronized cardioversion
What is the initial priority for an unconscious patient with any tachycardia on the monitor? - correct
answer -Determine whether pulses are present.
Which rhythm requires synchronized cardioversion? - correct answer -Unstable supraventricular
tachycardia
What is the recommended second dose of adenosine for patients in refractory but stable narrow-
complex tachycardia? - correct answer -12mg
What is the usual post-cardiac arrest target range for PETCO2 when ventilating a patient who achieves
return of spontaneous circulation (ROSC)? - correct answer -35-40mm Hg
Which condition is a contraindication to therapeutic hypothermia during the post-cardiac arrest period
for patients who achieve return of spontaneous circulation ROSC? - correct answer -Responding to
verbal commands
, What is the potential danger of using ties that pass circumferentially around the patient's neck when
securing an advanced airway? - correct answer -Obstruction of venous return from the brain
What is the most reliable method of confirming and monitoring correct placement of an endotracheal
tube? - correct answer -Continuous waveform capnography
hat is the recommended IV fluid (normal saline or Ringer's lactate) bolus dose for a patient who achieves
ROSC but is hypotensive during the post-cardiac arrest period? - correct answer -1 to 2 Liters
What is the minimum systolic blood pressure one should attempt to achieve with fluid, inotropic, or
vasopressor administration in a hypotensive post-cardiac arrest patient who achieves ROSC? - correct
answer -90mm Hg
What is the first treatment priority for a patient who achieves ROSC? - correct answer -Optimizing
ventilation and oxygenation.
What should be done to minimize interruptions in chest compressions during CPR? - correct answer -
Continue CPR while the defibrillator is charging.
Which condition is an indication to stop or withhold resuscitative efforts? - correct answer -Safety threat
to providers
After verifying the absence of a pulse, you initiate CPR with adequate bag-mask ventilation. The
patient's lead II ECG appears below. What is your next action? - correct answer -IV or IO access
After verifying unresponsiveness and abnormal breathing, you activate the emergency response team.
What is your next action? - correct answer -Check for a pulse.
What is the recommendation on the use of cricoid pressure to prevent aspiration during cardiac arrest?
- correct answer -Not recommended for routine use
