SECTION 1: BLS CORE CONTENT & GUIDELINES Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 67-year-old man collapses at a grocery store. A bystander starts CPR while another
retrieves the AED. Paramedics arrive 6 minutes later and find the patient in ventricular
fibrillation.
A. Immediate advanced life support by paramedics is the most critical link for survival
B. Early high-quality CPR initiated by the bystander is the most critical link for survival ✓
CORRECT
C. Rapid defibrillation performed in the ambulance is the most critical link for survival
D. Post-arrest hypothermia protocol at the hospital is the most critical link for survival
Correct Answer: B
,Rationale: Early high-quality CPR is the most critical link when EMS response exceeds
four minutes because it maintains minimal perfusion until defibrillation can occur.
Immediate ALS is important but cannot compensate for prolonged no-flow time.
Grocery store cardiac arrests with bystander intervention have significantly higher
survival rates than those waiting for EMS.
Question 2 of 50
During a resuscitation in the ED, the team leader asks the compressor to switch roles.
The compressor responds, "I will switch after the next rhythm check," and the leader
acknowledges.
A. Constructive intervention correcting an unsafe action
B. Clear message delivery using a calm tone of voice
C. Mutual respect between team members of different ranks
D. Closed-loop communication confirming the message was received and understood
✓ CORRECT
Correct Answer: D
Rationale: Closed-loop communication requires the receiver to acknowledge and
confirm the message, ensuring the team leader knows the instruction was understood.
A calm tone alone does not confirm receipt, and mutual respect is a broader team
dynamic element. Resuscitation teams that use closed-loop communication make
fewer errors during role transitions.
Question 3 of 50
A BLS student, 24, is performing chest compressions on an adult manikin during a skills
check. The instructor observes a compression rate of 140 per minute with incomplete
chest recoil.
A. Slow to 100-120 compressions per minute and allow full chest recoil ✓ CORRECT
, B. Increase depth to at least 2.5 inches to compensate for the faster rate
C. Maintain the current rate because faster compressions improve cardiac output
D. Pause compressions every minute to allow complete chest relaxation
Correct Answer: A
Rationale: The 2020 AHA guidelines specify a compression rate of 100 to 120 per
minute with full chest recoil to maximize coronary perfusion pressure. Faster rates
reduce filling time, and incomplete recoil further compromises preload. Instructors use
feedback devices to show students exactly when they are leaning or exceeding the
target rate.
Question 4 of 50
A 29-year-old is found in a parking lot with slow, gasping respirations and a palpable
carotid pulse. Naloxone is not immediately available.
A. Begin immediate chest compressions at a rate of 100 per minute
B. Place the patient in the recovery position and wait for EMS
C. Deliver one rescue breath every 6 seconds without compressions ✓ CORRECT
D. Perform 30 compressions followed by 2 breaths until naloxone arrives
Correct Answer: C
Rationale: When a pulse is present but breathing is inadequate, rescue breathing alone
at one breath every six seconds maintains oxygenation without unnecessary
compressions. Starting compressions on a patient with a pulse risks injury and
interrupts ventilation. BLS providers often encounter opioid emergencies where rescue
breathing bridges the gap until naloxone or advanced care arrives.
Question 5 of 50
A student asks why BLS starts with compressions rather than airway and breathing for
unresponsive adults.
A. Compressions are easier to teach to lay rescuers than airway maneuvers
