#1
In CPR, what is the primary purpose of rescue breaths?
To restore normal heart rhythm
To provide oxygen to the lungs
To stimulate the heart
To relieve pain
#2
What is the purpose of using an automated external defibrillator (AED) during cardiac arrest?
To administer medications
To monitor blood pressure
To deliver electrical shocks to restore normal heart rhythm
To provide oxygen support
#3
Which medication is commonly used during advanced cardiovascular life support (ACLS) to treat ventricular fibrillation or pulseless ventricular tachycardia?
Atropine
Amiodarone
Epinephrine
Dopamine
#4
Which of the following is a potential complication of administering epinephrine during CPR?
Decreased heart rate
Hypertension
Hypoglycemia
Bradycardia
#5
What is the recommended compression depth for adult patients during CPR?
At least 2 inches (5 cm)
At least 1 inch (2.5 cm)
At least 3 inches (7.5 cm)
At least 4 inches (10 cm)
#6
Which of the following is a common initial rhythm in sudden cardiac arrest?

International Resuscitation Council
#8
What is the recommended compression depth for pediatric patients during CPR?
At least 2 inches (5 cm)
At least 1 inch (2.5 cm)
At least 1.5 inches (4 cm)
At least 3 inches (7.5 cm)
#9
In the chain of survival, what does the 'early defibrillation' step emphasize?
Prompt administration of medications
Early initiation of chest compressions
Immediate use of an automated external defibrillator (AED)
Swift transport to the hospital
#10
During CPR, what is the recommended compression-ventilation ratio for a single rescuer on an adult patient?
#11
What is the purpose of administering epinephrine during cardiac arrest?
To decrease heart rate
To improve myocardial oxygenation
To induce vasodilation
To decrease blood pressure
#12
During CPR, what action should be taken if the chest fails to rise adequately during rescue breaths?
Increase the rate of compressions
Reposition the head and attempt rescue breaths again
Continue with compressions only
Administer additional epinephrine
#13
Which of the following is a common reversible cause of cardiac arrest?
Myocardial infarction
Hypovolemia
Pulmonary embolism
Aortic dissection
#14
During CPR, what is the purpose of checking for a pulse after every 2 minutes of chest compressions?
To assess responsiveness
To determine the need for rescue breaths
To evaluate the effectiveness of compressions
To administer additional medications
