#1
In CPR, what is the primary purpose of rescue breaths?
To provide oxygen to the lungs
ExplanationRescue breaths in CPR primarily aim to deliver oxygen to the lungs.
#2
What is the purpose of using an automated external defibrillator (AED) during cardiac arrest?
To deliver electrical shocks to restore normal heart rhythm
ExplanationAEDs deliver electrical shocks to restore normal heart rhythm during cardiac arrest.
#3
Which medication is commonly used during advanced cardiovascular life support (ACLS) to treat ventricular fibrillation or pulseless ventricular tachycardia?
Amiodarone
ExplanationAmiodarone is commonly used in ACLS to treat ventricular fibrillation or pulseless ventricular tachycardia.
#4
Which of the following is a potential complication of administering epinephrine during CPR?
Hypertension
ExplanationHypertension is a potential complication of administering epinephrine during CPR.
#5
What is the recommended compression depth for adult patients during CPR?
At least 2 inches (5 cm)
ExplanationEnsure adequate compression depth for effective CPR.
#6
Which of the following is a common initial rhythm in sudden cardiac arrest?
Ventricular Fibrillation
ExplanationVentricular Fibrillation is a common initial rhythm in sudden cardiac arrest.
#7
Which organization publishes the guidelines for cardiopulmonary resuscitation (CPR)?
American Heart Association
ExplanationThe American Heart Association publishes CPR guidelines.
#8
What is the recommended compression depth for pediatric patients during CPR?
At least 1.5 inches (4 cm)
ExplanationMaintain a compression depth of at least 1.5 inches (4 cm) for pediatric CPR.
#9
In the chain of survival, what does the 'early defibrillation' step emphasize?
Immediate use of an automated external defibrillator (AED)
ExplanationThe 'early defibrillation' step emphasizes immediate use of AEDs in the chain of survival.
#10
During CPR, what is the recommended compression-ventilation ratio for a single rescuer on an adult patient?
30:2
ExplanationMaintain a compression-ventilation ratio of 30:2 for a single rescuer on an adult patient.
#11
What is the purpose of administering epinephrine during cardiac arrest?
To improve myocardial oxygenation
ExplanationEpinephrine is given during cardiac arrest to enhance myocardial oxygenation.
#12
During CPR, what action should be taken if the chest fails to rise adequately during rescue breaths?
Reposition the head and attempt rescue breaths again
ExplanationReposition the head and retry rescue breaths if chest rise is inadequate during CPR.
#13
Which of the following is a common reversible cause of cardiac arrest?
Hypovolemia
ExplanationHypovolemia is a common reversible cause of cardiac arrest.
#14
During CPR, what is the purpose of checking for a pulse after every 2 minutes of chest compressions?
To evaluate the effectiveness of compressions
ExplanationChecking for a pulse after every 2 minutes of chest compressions evaluates compression effectiveness.
