#1
Which rhythm is considered a shockable rhythm in ACLS?
Ventricular fibrillation (VF)
ExplanationVentricular fibrillation is a shockable rhythm because it is a chaotic, disorganized rhythm that can be corrected with defibrillation.
#2
What is the correct compression to ventilation ratio for adult CPR?
30:2
ExplanationThe recommended compression to ventilation ratio for adult CPR is 30 compressions to 2 ventilations.
#3
Which medication is commonly administered during cardiac arrest for its antiarrhythmic properties?
Amiodarone
ExplanationAmiodarone is often given during cardiac arrest to help stabilize and treat abnormal heart rhythms.
#4
During ACLS, what is the recommended depth of chest compressions for adults?
At least 2 inches (5 centimeters)
ExplanationDuring ACLS, chest compressions for adults should be at least 2 inches deep to ensure adequate circulation.
#5
What is the recommended depth of chest compressions for pediatric patients during CPR?
At least 1.5 inches (4 centimeters)
ExplanationDuring CPR for pediatric patients, chest compressions should be at least 1.5 inches deep.
#6
Which rhythm is characterized by a wide QRS complex and absence of P waves on ECG?
Ventricular tachycardia (VT)
ExplanationVentricular tachycardia is identified by a wide QRS complex and absence of P waves on ECG.
#7
Which of the following is a reversible cause of cardiac arrest according to ACLS guidelines?
Hypoxia
ExplanationHypoxia, or lack of oxygen, is a reversible cause of cardiac arrest.
#8
What is the initial recommended dose of epinephrine during cardiac arrest in adults?
1 mg
ExplanationThe initial dose of epinephrine during adult cardiac arrest is 1 mg.
#9
What is the recommended initial energy setting for biphasic defibrillation in adult patients?
200 Joules
ExplanationThe recommended initial energy setting for biphasic defibrillation in adults is 200 Joules.
#10
What is the recommended route for administration of epinephrine during cardiac arrest in pediatric patients?
Intraosseous (IO)
ExplanationIn pediatric patients, epinephrine should be administered via the intraosseous route during cardiac arrest.
#11
In ACLS protocols, what is the recommended maximum interval for interruption of chest compressions?
10 seconds
ExplanationThe recommended maximum interval for interruption of chest compressions in ACLS protocols is 10 seconds.
#12
During ACLS, what is the preferred route for administration of amiodarone in adult patients with pulseless ventricular tachycardia (VT) or ventricular fibrillation (VF)?
Intravenous (IV) push
ExplanationThe preferred route for administering amiodarone in adult patients with pulseless VT or VF during ACLS is intravenous (IV) push.
