QUESTIONS AND ANSWERS PLUS RATIONALES GRADE A+ ASSURED(REAL DEAL)
Question 1
Which two interventions have the most significant positive impact on the outcome for a patient
in cardiac arrest?
A) Bag-mask ventilations and chest compressions
B) Early CPR and early defibrillation
C) Rapid transport and advanced life support
D) Oxygen administration and IV access
E) Chest compressions and medication administration
Correct Answer: B) Early CPR and early defibrillation
Rationale: The chain of survival emphasizes that immediate, high-quality CPR and rapid
defibrillation are the most critical factors in improving survival rates from out-of-hospital
cardiac arrest.
Question 2
After applying an AED to a patient in cardiac arrest, the machine delivers a "no shock advised"
message. What is the EMT's immediate next step?
A) Reassess the patient for a pulse.
B) Check the AED pad placement.
C) Resume chest compressions immediately.
D) Administer two rescue breaths.
E) Prepare the patient for transport.
Correct Answer: C) Resume chest compressions immediately.
Rationale: If no shock is advised, it means the patient is in a non-shockable rhythm (like
asystole or PEA) or has regained a pulse. In either case, the immediate priority is to resume
high-quality chest compressions to maintain circulation until the next rhythm analysis.
Question 3
What is the maximum amount of time an EMT should take to check for breathing and a pulse in
an unresponsive patient?
,A) 5 seconds
B) 10 seconds
C) 15 seconds
D) 20 seconds
E) 30 seconds
Correct Answer: B) 10 seconds
Rationale: To minimize interruptions in chest compressions, the check for breathing and a
pulse should be brief, lasting no more than 10 seconds.
Question 4
When performing two-rescuer CPR on an adult, what is the correct compression-to-ventilation
ratio?
A) 15:1
B) 15:2
C) 30:1
D) 30:2
E) Continuous compressions with one breath every 6 seconds
Correct Answer: D) 30:2
Rationale: For both one- and two-rescuer adult CPR, the recommended ratio is 30
compressions followed by 2 ventilations.
Question 5
When assessing for a pulse in an infant, which artery is the most appropriate to palpate?
A) Carotid
B) Femoral
C) Radial
D) Brachial
E) Popliteal
Correct Answer: D) Brachial
Rationale: The brachial artery, located on the inside of the upper arm, is the most reliable and
accessible pulse point for an infant.
,Question 6
During CPR on an adult or child, how often should the rescuers pause to reassess for a pulse and
spontaneous breathing?
A) Every 1 minute
B) Every 2 minutes (after 5 cycles)
C) Every 3 minutes
D) Every 5 minutes
E) Only when the AED advises
Correct Answer: B) Every 2 minutes (after 5 cycles)
Rationale: Resuscitation guidelines recommend a brief pause for reassessment approximately
every 2 minutes, which corresponds to the completion of 5 cycles of 30:2 CPR.
Question 7
What is the preferred method for attempting to clear a severe airway obstruction in an
unresponsive child?
A) Back blows
B) Abdominal thrusts (Heimlich maneuver)
C) Finger sweeps
D) Chest compressions
E) Bag-mask ventilations
Correct Answer: D) Chest compressions
Rationale: For an unresponsive choking victim (adult or child), chest compressions are
performed. This is the same action as in CPR, and it can help generate enough pressure to
dislodge the foreign body.
Question 8
What is the underlying cause of cardiogenic shock?
A) A severe allergic reaction
B) Widespread vasodilation due to infection
C) Inadequate pumping function of the heart
D) A significant loss of blood or fluid volume
, E) Obstruction of a major blood vessel
Correct Answer: C) Inadequate pumping function of the heart
Rationale: Cardiogenic shock occurs when the heart muscle is so damaged (e.g., from a large
heart attack) that it can no longer pump a sufficient amount of blood to meet the body's
needs.
Question 9
A collection of fluid between the pericardial sac and the myocardium is known as:
A) Aortic aneurysm
B) Myocardial infarction
C) Congestive heart failure
D) Pericardial effusion
E) Pneumothorax
Correct Answer: D) Pericardial effusion
Rationale: This is the definition of a pericardial effusion. If the fluid accumulates rapidly, it can
lead to cardiac tamponade.
Question 10
A patient has jugular vein distention, muffled heart sounds, and a narrowing pulse pressure.
This classic triad of signs is known as Beck's triad and is indicative of:
A) Acute myocardial infarction
B) Cardiogenic shock
C) Cardiac tamponade
D) Congestive heart failure
E) Hypertensive emergency
Correct Answer: C) Cardiac tamponade
Rationale: Beck's triad is the hallmark physical exam finding for cardiac tamponade, a
condition where fluid in the pericardial sac compresses the heart and prevents it from filling
properly.
