#1
Which of the following is a common cause of cardiac arrest?
Electrical abnormalities in the heart
ExplanationCardiac arrest often results from electrical issues in the heart's function.
#2
What is the recommended initial step in managing a witnessed adult cardiac arrest?
Call for help
ExplanationPromptly calling for assistance is crucial in the early management of adult cardiac arrest.
#3
What is the recommended compression rate during CPR for adult patients?
100-120 compressions per minute
ExplanationMaintaining a compression rate within the specified range is essential for effective adult CPR.
#4
What is the purpose of administering epinephrine during advanced cardiac life support (ACLS)?
To improve blood flow to the heart
ExplanationEpinephrine is used to enhance blood circulation during advanced cardiac life support (ACLS).
#5
Which medication is commonly used for treating ventricular fibrillation during advanced cardiac life support (ACLS)?
Amiodarone
ExplanationAmiodarone is commonly used to address ventricular fibrillation in advanced cardiac life support (ACLS) scenarios.
#6
What is the recommended depth for chest compressions during adult CPR?
4-5 centimeters
ExplanationMaintaining a compression depth within the specified range is crucial for effective adult CPR.
#7
Which of the following is NOT a sign of effective CPR in an unconscious adult patient?
Return of spontaneous circulation (ROSC)
ExplanationROSC is not an immediate indicator of effective CPR in unconscious adult patients.
#8
What is the recommended compression-to-ventilation ratio for adult CPR performed by a single rescuer?
30:2
ExplanationThe recommended ratio for chest compressions to ventilations in adult CPR performed by a single rescuer.
#9
Which of the following is a common reversible cause of cardiac arrest?
Hypoxia
ExplanationHypoxia, a lack of oxygen, is a common reversible factor leading to cardiac arrest.
#10
Which rhythm is shockable in cardiac arrest according to ACLS guidelines?
Ventricular fibrillation (VF)
ExplanationVentricular fibrillation is a shockable rhythm requiring immediate intervention in cardiac arrest.
#11
During advanced cardiac life support (ACLS), when is it appropriate to consider terminating resuscitation efforts?
After 20 minutes of CPR
ExplanationConsideration for stopping resuscitation efforts after a specified duration in advanced cardiac life support (ACLS).
#12
Which rhythm requires immediate defibrillation during pediatric cardiac arrest?
Ventricular fibrillation (VF)
ExplanationVentricular fibrillation in pediatric cardiac arrest requires immediate defibrillation intervention.
