#1
What is the first step in Basic Life Support (BLS) for an unresponsive adult?
Open the airway
ExplanationInitiate airway management to ensure proper oxygen flow.
#2
Which medication is commonly administered during a cardiac arrest to help restart the heart?
Epinephrine
ExplanationEpinephrine is given to enhance cardiac output and circulation.
#3
What is the recommended depth of chest compressions for adult CPR?
2 inches (5 cm)
ExplanationAim for a compression depth of at least 2 inches (5 cm) in adult CPR.
#4
Which of the following is a common sign of an acute myocardial infarction (heart attack)?
Chest pain or discomfort
ExplanationAcute myocardial infarction often presents with chest pain or discomfort.
#5
What is the recommended compression rate during CPR for both adults and children?
100 compressions per minute
ExplanationMaintain a compression rate of 100 compressions per minute during CPR.
#6
Which of the following is a common side effect of administering epinephrine during a cardiac arrest?
Tachycardia
ExplanationEpinephrine may cause an increase in heart rate (tachycardia).
#7
In the context of emergency cardiovascular care, what is the purpose of defibrillation?
To restore a normal heart rhythm
ExplanationDefibrillation aims to return the heart to a normal rhythm.
#8
Which of the following is a reversible cause of cardiac arrest?
Hypothermia
ExplanationHypothermia can be addressed to potentially reverse cardiac arrest.
#9
What is the recommended compression depth during CPR for infants?
At least 1.5 inches
ExplanationEnsure a compression depth of at least 1.5 inches in infant CPR.
#10
What does the acronym ACLS stand for in the context of emergency cardiovascular care?
Advanced Cardiovascular Life Support
ExplanationACLS involves advanced measures for cardiovascular emergency care.
#11
What is the correct ratio of chest compressions to rescue breaths in adult CPR?
30:2
ExplanationFollow the 30:2 ratio for effective chest compressions and rescue breaths in adult CPR.
#12
Which antiarrhythmic medication is commonly used in the treatment of ventricular fibrillation or pulseless ventricular tachycardia?
Amiodarone
ExplanationAmiodarone is often administered to address ventricular arrhythmias.
#13
Which of the following is a common side effect of administering amiodarone?
Hypotension
ExplanationAmiodarone may lead to hypotension as a side effect.
#14
Which rhythm is most commonly associated with pulseless electrical activity (PEA)?
Asystole
ExplanationAsystole is often associated with pulseless electrical activity (PEA).
