- What are the two shockable rhythms in cardiac arrest?
Show answer
Ventricular fibrillation and pulseless ventricular tachycardia.- What are the two nonshockable rhythms in cardiac arrest?
Show answer
Asystole and pulseless electrical activity (PEA).- In adult cardiac arrest, ____ is a chaotic rhythm with no organized electrical activity and no pulse.
Show answer
Ventricular fibrillation (VF)- ____ is an organized wide-complex rhythm that produces no palpable pulse.
Show answer
Pulseless ventricular tachycardia (pVT)- What is PEA (pulseless electrical activity)?
Show answer
An organized electrical rhythm seen on the monitor with no palpable pulse.- What rhythm appears as a flat line with no electrical activity?
Show answer
Asystole.- What is the initial biphasic defibrillation energy for adult VF/pVT?
Show answer
120 to 200 joules (per manufacturer recommendation).- What is the initial monophasic defibrillation energy for adult VF/pVT?
Show answer
360 joules.- If the initial biphasic shock dose is unknown, what energy should be used?
Show answer
The maximum available energy.- Should defibrillation energy for subsequent shocks be lower, equal, or higher than the first shock?
Show answer
Equal or higher (escalating) energy.- The standard IV/IO dose of epinephrine given during cardiac arrest is ____.
Show answer
1 mg- How often is epinephrine redosed during cardiac arrest?
Show answer
Every 3 to 5 minutes.- In a nonshockable arrest (PEA/asystole), when should epinephrine first be given?
Show answer
As soon as possible after the rhythm is identified.- In a shockable arrest (VF/pVT), when is epinephrine first given?
Show answer
After the second defibrillation attempt fails.- The first dose of amiodarone for refractory VF/pVT is a ____ IV/IO bolus.
Show answer
300 mg
