#1
Which rhythm is considered a shockable rhythm in ACLS?
Ventricular fibrillation
ExplanationVentricular fibrillation is characterized by chaotic electrical activity in the heart and requires defibrillation.
#2
What does CAB stand for in the CAB algorithm of CPR?
Circulation, Airway, Breathing
ExplanationCAB stands for Circulation, Airway, Breathing, representing the order of priorities in CPR.
#3
Which rhythm is characterized by a lack of organized electrical activity and no pulse in ACLS?
Asystole
ExplanationAsystole is the absence of cardiac electrical activity and pulse, requiring immediate intervention.
#4
Which of the following is a reversible cause of cardiac arrest according to ACLS algorithms?
Hypovolemia
ExplanationHypovolemia, or low blood volume, is a reversible cause of cardiac arrest according to ACLS algorithms.
#5
What is the first step in the ACLS algorithm for managing a patient with cardiac arrest?
Assess for responsiveness
ExplanationAssessing for responsiveness is the first step in the ACLS algorithm for managing a patient with cardiac arrest.
#6
Which medication is commonly used during ACLS for ventricular fibrillation and pulseless ventricular tachycardia?
Amiodarone
ExplanationAmiodarone is an antiarrhythmic medication used to stabilize heart rhythms during cardiac arrest.
#7
What is the recommended depth of chest compressions during adult CPR?
2 inches (5 cm)
ExplanationThe recommended depth of chest compressions during adult CPR is 2 inches or 5 cm.
#8
What is the recommended compression-to-ventilation ratio for adult CPR?
30:2
ExplanationThe recommended compression-to-ventilation ratio for adult CPR is 30 compressions to 2 ventilations.
#9
During CPR, how often should rescuers switch positions when performing chest compressions?
Every 2 minutes
ExplanationRescuers should switch positions every 2 minutes during CPR to prevent fatigue and maintain effective compressions.
#10
What is the recommended depth of chest compressions for pediatric CPR?
1.5 inches (4 cm)
ExplanationThe recommended depth of chest compressions for pediatric CPR is 1.5 inches or 4 cm.
#11
What is the initial recommended energy for defibrillation of ventricular fibrillation or pulseless ventricular tachycardia in adults?
360 joules
ExplanationThe initial recommended energy for defibrillation in adults with ventricular fibrillation or pulseless ventricular tachycardia is 360 joules.
#12
What is the recommended dose of epinephrine during ACLS for adults with cardiac arrest?
0.1 mg
ExplanationThe recommended dose of epinephrine during ACLS for adults with cardiac arrest is 0.1 mg.
#13
What is the recommended dose of atropine for symptomatic bradycardia during ACLS?
1 mg
ExplanationThe recommended dose of atropine for symptomatic bradycardia during ACLS is 1 mg.
#14
What is the recommended dose of lidocaine for ventricular fibrillation or pulseless ventricular tachycardia in ACLS?
0.5 mg/kg
ExplanationThe recommended dose of lidocaine for ventricular fibrillation or pulseless ventricular tachycardia in ACLS is 0.5 mg/kg.
#15
What is the recommended dose of vasopressin during ACLS for adults with cardiac arrest?
0.4 mg
ExplanationThe recommended dose of vasopressin during ACLS for adults with cardiac arrest is 0.4 mg.
