Answers & Detailed Rationales | Verified &

1.
A patient suddenly becomes unresponsive in a medical
treatment facility. The patient is not breathing normally and
has no definite signs of circulation. What should the 4N0X1 do
first after determining the patient is unresponsive?
A. Obtain a 12-lead ECG
B. Activate the emergency response system and begin high-
quality CPR
C. Establish an IV before beginning compressions
D. Obtain a complete medical history
Rationale: The priority in an unresponsive patient who is not
breathing normally is immediate recognition of cardiac arrest,
activation of the emergency response system, and initiation of
high-quality CPR. Delaying compressions for an ECG, IV access,
,or a detailed history unnecessarily interrupts time-critical
resuscitation.
2.
During adult CPR before an advanced airway is placed, which
compression-to-ventilation pattern is consistent with current
AHA guidance?
A. 15:2
B. 20:2
C. 30:2
D. 50:5
Rationale: Current adult basic life support guidance continues
to support cycles of 30 chest compressions followed by 2
breaths before placement of an advanced airway. Maintaining
effective compressions while providing appropriate ventilation
is central to high-quality CPR.
3.
An adult patient in cardiac arrest has failed initial attempts at IV
access. Which vascular access approach is recommended next
when IV access cannot be promptly established?
,A. Central venous catheterization by the technician
B. Intraosseous access
C. Intraosseous access after unsuccessful initial IV attempts
D. Delay vascular access until spontaneous circulation returns
Rationale: The 2025 AHA guidance recommends initial IV
attempts for adults in cardiac arrest, with IO access used when
IV attempts are unsuccessful. The important principle is to
obtain reliable vascular access without allowing access
attempts to cause prolonged interruption of resuscitation.
4.
A conscious adult suddenly develops severe airway obstruction
while eating. Which sequence is recommended for severe
foreign-body airway obstruction?
A. Five abdominal thrusts followed by five back blows
B. Continuous abdominal thrusts only
C. Five back blows followed by five abdominal thrusts,
repeated as needed
D. Blind finger sweeps followed by chest compressions
Rationale: The 2025 AHA guidance streamlined management
of severe foreign-body airway obstruction to alternating
cycles of five back blows and five abdominal thrusts,
beginning with back blows. Blind finger sweeps should not be
, performed because they can push an obstruction farther into
the airway.
5.
An adult remains unresponsive after return of spontaneous
circulation and does not respond to verbal commands. Which
post-cardiac-arrest intervention is specifically emphasized in
current guidance?
A. Immediate discontinuation of all temperature monitoring
B. Routine induction of severe hypothermia
C. Temperature control for at least 36 hours
D. Maintaining body temperature above 40°C
Rationale: Current AHA guidance emphasizes temperature
control in adults who remain unresponsive to verbal
commands after cardiac arrest, with recommendations
supporting temperature control for at least 36 hours. The
objective is controlled temperature management rather than
uncontrolled fever or arbitrary deep hypothermia.
