Pulseless Electrical Activity / Asystole Practice Test

What are the 2 most common causes of Pulseless Electrical Activity?

Question 1/10

Hypothermia and hypoxia

Hypovolemia and hypoxia

Hypovolemia and hyperkalemia

Hypoxia and hyperkalemia

What is the correct dosing regimen of epinephrine to treat PEA or Asystole?

Question 2/10

300 mg bolus

1 mg IV/IO - repeated every 8 to 10 minutes

1 mg IV/IO - repeated every 3 to 5 minutes

.5 mg IV/IO - repeated every 8 to 10 minutes

Pulseless Electrical Activity is defined as:

Question 3/10

No electrical activity present on an ECG

A perfusing rhythm without spontaneous respirations

Ventricular Fibrillation

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.

Next question

Possible causes of an isoelectric ECG (Flat line) include:

Question 4/10

Loose leads or leads not connected to the patient or defibrillator/monitor

No power to the monitor

Gain or amplitude too low

All of the above

Which of the following is not a reason to stop or withhold resuscitative efforts?

Question 5/10

Rigor mortis

Indicators of do-not-attempt-resuscitation (DNAR) status

Threat to safety of providers

Resuscitation effort have been unsuccessful for 20 minutes or more

Routine insertion of an advanced airway in asystole:

Question 6/10

Is contraindicated in a patient in asystole

Should take priority over gaining IV/IO access

Should only be performed if ventilations with a BVM are ineffective

Is necessary so the epinephrine can be given

The first dose of amiodarone for PEA treatment is:

Question 7/10

150 mg

300 mg

100 mg

Amiodarone is not used in PEA

Which of the following statements is not true?

Question 8/10

CPR should not be stopped to administer drugs to PEA or Asystole patients

Treatment of PEA is limited to interventions outlined in the algorithm

IV/IO access is a priority over advanced airway management

Epinephrine is a common treatment for PEA and Asystole

Which of the following statements is true?

Question 9/10

There is no evidence that attempting to "defibrillate" asystole is beneficial

The AHA recommends the use of TCP for patients with asystolic cardiac arrest

CPR should be interrupted while establishing IV or IO access in asystole patients

Identifying the cause of asystole is not important

PEA and Asystole are shockable rhythms

Question 10/10

True

False
