Pass
What are the 2 most common causes of Pulseless Electrical Activity?
A. Hypothermia and hypoxia
B. Hypovolemia and hypoxia
C. Hypovolemia and hyperkalemia
D. Hypoxia and hyperkalemia ✔Correct Answer-B. Hypovolemia and hypoxia
Hypovolemia and hypoxia are the 2 most common underlying and potentially reversible causes of
PEA. Be sure to look for evidence of these problems as you assess the patient.
What is the correct dosing regimen of epinephrine to treat PEA or Asystole?
A. 300 mg bolus
B. 1 mg IV/IO - repeated every 8 to 10 minutes
C. 1 mg IV/IO - repeated every 3 to 5 minutes
D. 0.5 mg IV/IO - repeated every 8 to 10 minutes ✔Correct Answer-C. 1 mg IV/IO - repeated every 3
to 5 minutes
Pulseless Electrical Activity is defined as:
A. No electrical activity present on an ECG
B. A perfusing rhythm without spontaneous respirations
C. Ventricular Fibrillation
D. Any organized rhythm without a pulse ✔Correct Answer-D. Any organized rhythm without a
pulse
Any organized rhythm without a pulse is defined as PEA. An organized rhythm consists of QRS
complexes that are similar in appearance from beat to beat (ie, each has a uniform QRS
configuration). Organized rhythms may have narrow or wide QRS complexes, they may occur at rapid
or slow rates, they may be regular or irregular, and they may or may not produce a pulse.
Possible causes of an isoelectric ECG (Flat line) include:
A. Loose leads or leads not connected to the patient or defibrillator/monitor
B. No power to the monitor
C. Gain or amplitude too low
D. All of the above ✔Correct Answer-D. All of the above
Which of the following is not a reason to stop or withhold resuscitative efforts?
A.Rigor mortis
B.Indicators of do-not-attempt-resuscitation (DNAR) status
C.Threat to safety of providers
D.Resuscitation effort have been unsuccessful for 20 minutes or more ✔Correct Answer-
D.Resuscitation effort have been unsuccessful for 20 minutes or more
The final decision to stop resuscitative efforts can never be as simple as an isolated time interval.
Routine insertion of an advanced airway in asystole:
A.Is contraindicated in a patient in asystole
B.Should take priority over gaining IV/IO access
C.Should only be performed if ventilations with a BVM are ineffective
D.Is necessary so the epinephrine can be given ✔Correct Answer-C.Should only be performed if
ventilations with a BVM are ineffective
