#1
Which of the following is a common cause of cardiac arrest?
Heart attack
ExplanationHeart attack can disrupt the heart's normal rhythm, leading to cardiac arrest.
#2
What is the purpose of the 'recovery position' in first aid?
To maintain an open airway in an unconscious breathing person
ExplanationIt helps prevent airway obstruction and facilitates breathing.
#3
Which of the following is a common sign of sudden cardiac arrest?
Chest pain
ExplanationChest pain can sometimes be a warning sign before sudden cardiac arrest occurs.
#4
Which of the following is a common risk factor for cardiovascular diseases?
High blood pressure
ExplanationHigh blood pressure increases the risk of heart diseases and cardiac events.
#5
What is the primary purpose of the 'ABC' sequence in assessing a patient's condition?
To check for Airway, Breathing, and Circulation
ExplanationABC sequence helps assess and prioritize life-saving interventions.
#6
What is the recommended depth for chest compressions during CPR for adults?
2 inches
ExplanationEffective chest compressions should compress the chest at least 2 inches.
#7
In the chain of survival, what does 'Early Defibrillation' refer to?
Early use of an automated external defibrillator (AED)
ExplanationPrompt use of AED can restore normal heart rhythm, increasing chances of survival.
#8
Which of the following rhythms is shockable in cardiac arrest?
Ventricular Fibrillation
ExplanationVentricular Fibrillation requires defibrillation to restore normal heart rhythm.
#9
What is the purpose of the 'C-A-B' sequence in CPR?
To prioritize chest compressions over rescue breaths
ExplanationChest compressions are prioritized to maintain circulation and oxygenation.
#10
What is the purpose of the AED (Automated External Defibrillator) in cardiac resuscitation?
To deliver an electric shock to restore a normal heart rhythm
ExplanationAED administers an electric shock to correct abnormal heart rhythms.
#11
During CPR for an infant, what is the recommended depth for chest compressions?
1 inch
ExplanationChest compressions for infants should be approximately 1 inch deep.
#12
What does the term 'BLS' stand for in the context of resuscitation?
Basic Life Support
ExplanationBLS includes basic procedures like chest compressions and rescue breaths to sustain life.
#13
During CPR, what is the purpose of rescue breaths?
To provide oxygen to the lungs
ExplanationRescue breaths aim to deliver oxygen to maintain oxygenation and support life.
#14
Which medication is commonly administered during advanced cardiac life support (ACLS) for arrhythmias?
Epinephrine
ExplanationEpinephrine helps stimulate the heart and improve circulation in cardiac emergencies.
#15
What is the recommended compression-to-ventilation ratio for adult CPR?
30:2
ExplanationFor adults, the recommended ratio is 30 compressions to 2 breaths.
#16
What is the purpose of the 'head tilt-chin lift' maneuver in opening the airway?
To clear the airway of obstructions
ExplanationIt helps remove any blockages and facilitates breathing.
#17
In pediatric CPR, what is the recommended compression-to-ventilation ratio?
30:2
ExplanationSimilar to adult CPR, the ratio for children is 30 compressions to 2 breaths.
