#1
What is the first step in the Chain of Survival for cardiovascular resuscitation?
Early recognition and activation of emergency response
ExplanationImmediate recognition and activation of emergency services are crucial for increasing survival rates.
#2
Which of the following is a common early sign of a heart attack?
Chest pain or discomfort
ExplanationChest pain is a classic symptom indicating a potential heart attack.
#3
What does CPR stand for in Cardiovascular Resuscitation?
Cardiopulmonary Resuscitation
ExplanationCPR involves techniques to maintain blood circulation and provide oxygen to the body during cardiac arrest.
#4
Which of the following is a common cause of cardiac arrest in adults?
Coronary artery disease
ExplanationCoronary artery disease is a leading cause of cardiac arrest due to blockages in blood flow.
#5
Which of the following is a common symptom of angina?
Chest pain or discomfort
ExplanationAngina typically presents as chest discomfort due to reduced blood flow to the heart.
#6
During CPR, what is the recommended compression depth for an adult victim?
2 inches (5 cm)
ExplanationCompressions should be deep enough to adequately pump blood through the heart.
#7
Which rhythm is considered shockable during cardiac arrest, making defibrillation effective?
Ventricular fibrillation (VF)
ExplanationVentricular fibrillation is a chaotic heart rhythm that can be corrected with defibrillation.
#8
During CPR, what is the recommended compression depth for adults?
2 inches (5 cm)
ExplanationEffective compressions should be deep enough to effectively pump blood.
#9
Which rhythm is shockable in the context of advanced life support (ALS)?
Ventricular Fibrillation (VF)
ExplanationVF is one of the few shockable rhythms that require immediate defibrillation.
#10
What is the purpose of an automated external defibrillator (AED) during resuscitation?
To deliver an electric shock to restore heart rhythm
ExplanationAEDs are vital in restoring normal heart rhythms during sudden cardiac arrest.
#11
What is the purpose of administering epinephrine during cardiac arrest resuscitation?
To increase blood pressure and improve coronary perfusion
ExplanationEpinephrine helps to maintain blood flow to vital organs during resuscitation efforts.
#12
In pediatric CPR, what is the recommended compression depth for an infant victim?
1.5 inches (4 cm)
ExplanationCompressions should be gentler but still effective in infants to prevent injury.
#13
What is the recommended ratio of chest compressions to rescue breaths in CPR for adults?
30:2
ExplanationThis ratio ensures adequate circulation and oxygenation during CPR.
#14
What is the acronym FAST used for in the context of recognizing a stroke?
Facial drooping, Arm weakness, Speech difficulties, Time to call emergency services
ExplanationFAST helps identify common symptoms of stroke for prompt medical attention.
#15
What is the primary purpose of an advanced airway device, such as an endotracheal tube, in resuscitation?
To provide oxygen directly to the lungs
ExplanationAdvanced airway devices ensure efficient oxygenation during resuscitation efforts.
