AAOS EMERGENCY CARE AND TRANSPORTATION
OF THE SICK AND INJURED 12TH EDITION —
COMPLETE NREMT AND EMT INSTRUCTOR TEST
BANK (QUESTIONS AND ANSWERS + DEEP
RATIONALES)
This comprehensive, high-yield EMT exam study resource
delivers rigorous, multiple-choice practice questions
mapped directly to the current National EMS Education
Standards. Every professional-grade question includes the
correct answer alongside a deeply detailed, bolded rationale
designed to cement critical core concepts in airway
management, cardiology, trauma, and medical emergencies.
Perfect for students preparing for course finals or the
NREMT exam, this premium test bank serves as an essential
tool to guarantee first-time passing success.
Question 1
A 67-year-old male presents with sudden onset of tearing chest
pain that radiates to his back between the scapulae. He is sweaty
and has a blood pressure of 160/90 mmHg in his right arm and
130/70 mmHg in his left arm. What should you suspect?
A) Acute myocardial infarction
B) Acute aortic dissection
C) Pulmonary embolism
D) Spontaneous pneumothorax
,Answer: B
Rationale: A tearing or ripping chest pain that radiates
directly to the back, combined with a significant blood
pressure differential between the upper extremities (greater
than 20 mmHg), is a classic presentation of an acute aortic
dissection. An acute myocardial infarction typically causes
crushing or pressure-like pain. Pulmonary embolism pain is
usually pleuritic (sharp and worse with deep breaths) and
associated with sudden dyspnea. Spontaneous
pneumothorax causes sudden unilateral chest pain and
localized decreased breath sounds.
Question 2
You are treating an unresponsive 4-year-old child who has a
pulse rate of 52 beats/min with poor systemic perfusion despite
adequate oxygenation and ventilation. What is your next
immediate action?
A) Continue providing high-flow oxygen via a nonrebreather
mask.
B) Administer abdominal thrusts to clear a suspected airway
obstruction.
C) Begin chest compressions at a ratio of 15:2.
D) Transport immediately without any further interventions.
Answer: C
Rationale: According to AHA and pediatric resuscitation
guidelines, if a pediatric patient (infant or child) has a heart
rate below 60 beats/min with signs of poor perfusion despite
optimal ventilation and oxygenation, you must immediately
begin chest compressions. For a child with two rescuers
,(standard EMS team), the compression-to-ventilation ratio is
15:2. Continuing passive oxygenation or delaying
compressions for transport will worsen myocardial hypoxia
and lead to cardiac arrest.
Question 3
Which of the following biological agents is highly contagious from
person to person and presents with high fever, headache, and a
progressive blister-like rash that develops at the same stage
across the body?
A) Anthrax
B) Smallpox
C) Ricin
D) Botulinum toxin
Answer: B
Rationale: Smallpox is a highly contagious viral agent spread
through respiratory droplets or direct contact. Its hallmark is
a rash where all lesions develop at the same stage
simultaneously (unlike chickenpox, where lesions are in
various stages). Anthrax is generally not contagious from
person to person. Ricin and botulinum are toxins and cannot
be spread from person to person.
Question 4
A 22-year-old female is found unresponsive in an alleyway. She
has slow, shallow respirations at 6 breaths/min, pinpoint pupils,
and cyanosis around her lips. Which medication is most indicated
, for this patient?
A) Epinephrine 1:1,000
B) Albuterol MDI
C) Naloxone
D) Oral glucose
Answer: C
Rationale: The clinical triad of unresponsiveness, severe
respiratory depression (6 breaths/min), and pinpoint (miotic)
pupils strongly indicates an opioid overdose. Naloxone is a
competitive opioid antagonist designed to reverse
respiratory depression. Epinephrine is used for anaphylaxis
or cardiac arrest. Albuterol is for bronchospasm, and oral
glucose requires a conscious patient who can swallow.
Question 5
During the delivery of a newborn, you note that the umbilical cord
is wrapped tightly around the baby’s neck. This condition is known
as a:
A) Prolapsed cord
B) Nuchal cord
C) Breech cord
D) Cord presentation
Answer: B
Rationale: A nuchal cord occurs when the umbilical cord
becomes wrapped around the fetus's neck. If it is loose, it
can gently be slipped over the head. If it is too tight, it must
be clamped and cut immediately to prevent strangulation or
hypoxia. A prolapsed cord is when the cord slips out of the
