VF / Pulseless VT Practice Test

VF and Pulseless VT are shockable rhythms

Question 1/10

If the initial shock terminates VF but the arrhythmia recurs later in the resuscitation:

Question 2/10
Deliver subsequent shocks at the maximum energy dose
Deliver subsequent shocks at the previously successful energy level
Do not deliver any subsequent shocks and continue CPR
Begin cardioversion

For every minute that passes between collapse and defibrillation, how much does the chance of survival decrease from a witnessed VF sudden cardiac arrest if no bystander CPR is provided?

Question 3/10
7% to 10%
3% to 4%
25% to 30%
50% to 60%

Pulse checks should:

Question 4/10
Performed every 50 cycles of CPR
Be performed during rhythm analysis, only if an organized rhythm is present
Take at least 15 seconds to ensure accuracy
Give the rescuer enough information to treat the victim

What is the first-line antiarrhythmic agent given in cardiac arrest?

Question 5/10
Magnesium sulfate

Defibrillation restarts the heart

Question 6/10

If using a biphasic defibrillator and the recommended dosage is not known:

Question 7/10
Do not shock until the recommended dose has been identified
Shock using the minimum energy dose available
Shock using a 360 J energy dose
Shock using the maximum energy dose available

The proper dosing of epinephrine for VF/pVT is:

Question 8/10
1 mg IV/IO - repeated every 3 to 5 minutes
300 mg IV/IO bolus
1 to 2 g IV/IO diluted in 10 mL saline over 5 to 20 minutes
0.5 to 0.75 mg/kg IV/IO

Epinephrine is used during resuscitation:

Question 9/10
Because it causes vasoconstriction
To stop allergic reactions causing heart failure
As a pain reliever for the victim
Because it is an antiarrhythmic

The chest compression fraction should be:

Question 10/10
As high as possible
At least 50%
Lower than 25%
Lower than 60%
