#1
What is the correct compression-to-ventilation ratio for CPR in adults?
30 compressions to 2 ventilations
ExplanationMore compressions than ventilations for effective adult CPR.
#2
What does the 'C' stand for in the acronym 'CPR'?
Cardiac
ExplanationCPR focuses on the heart.
#3
What is the first step in the BLS algorithm for adults?
Check for responsiveness
ExplanationAssessing responsiveness initiates the BLS protocol.
#4
Which of the following is NOT a common cause of cardiac arrest?
Stroke
ExplanationStroke doesn't typically lead to cardiac arrest.
#5
What is the recommended compression-to-ventilation ratio for CPR in infants?
30 compressions to 1 ventilation
ExplanationInfant CPR requires a different ratio than adults.
#6
What is the correct hand placement for chest compressions in infant CPR?
Between the nipples
ExplanationSpecific hand placement is essential for infant CPR.
#7
Which of the following is NOT a sign of effective CPR?
Coughing by the patient
ExplanationCoughing isn't indicative of effective CPR.
#8
What is the recommended depth for chest compressions during adult CPR?
At least 2 inches (5 centimeters)
ExplanationDepth is crucial for effective compressions.
#9
What is the recommended compression rate for CPR in adults?
At least 100 compressions per minute
ExplanationRapid compressions maintain blood flow.
#10
During CPR, where should you position your hands for chest compressions on an adult?
Over the lower half of the sternum
ExplanationCorrect hand placement ensures effective compressions.
#11
What is the purpose of the 'airway' component in the BLS algorithm?
To ensure adequate oxygenation
ExplanationMaintaining an open airway is crucial for oxygenation.
#12
What is the preferred method for opening the airway in an unresponsive patient?
Jaw thrust maneuver
ExplanationJaw thrust is safer in suspected cervical spine injury cases.
#13
What should you do before starting CPR on an unconscious adult?
Check for a pulse
ExplanationPulse check is vital to determine if CPR is necessary.
#14
What is the recommended compression depth for infant CPR?
At least 1.5 inches (4 centimeters)
ExplanationDepth requirement varies for infants.
#15
What is the recommended ventilation rate for CPR in adults?
1 breath every 10 seconds
ExplanationVentilation rate is slower than compressions for adults.
#16
During CPR, what should you do if the patient's chest does not rise with rescue breaths?
Repeat the breath
ExplanationEnsure effective ventilation by repeating the breath.
#17
What is the preferred method for checking for breathing in an infant?
Look, listen, and feel for breathing
ExplanationMultiple senses are used to assess breathing in infants.
