EMT-B – Emergency Medical Technician Basic Practice Exam
Updated 2026 | Complete Study Guide with Verified Questions and
Detailed Rationales | Airway and Breathing Management, Patient
Assessment, Trauma Care, Medical Emergencies, CPR and AED
Use, Bleeding Control, Shock Management, EMS Operations, and
Prehospital Emergency Care for EMT-B Certification Success
Question 1: What is the first step in the primary assessment of an unresponsive
patient?
A. Check for breathing
B. Open the airway
C. Assess circulation
D. Determine responsiveness
CORRECT ANSWER: D. Determine responsiveness
RATIONALE: The primary assessment begins with determining the patient's level of
responsiveness using the AVPU scale (Alert, Voice, Pain, Unresponsive). This initial step
guides all subsequent interventions, as an unresponsive patient requires immediate
airway management. Checking breathing, opening the airway, or assessing circulation
occur after establishing responsiveness per the standard EMS assessment sequence.
Question 2: Which of the following is the most appropriate method for opening the
airway of a trauma patient with suspected cervical spine injury?
A. Head-tilt/chin-lift maneuver
B. Jaw-thrust maneuver
C. Modified jaw-thrust with head extension
D. Nasopharyngeal airway insertion without manual stabilization
CORRECT ANSWER: B. Jaw-thrust maneuver
RATIONALE: The jaw-thrust maneuver is the preferred technique for opening the airway
in trauma patients with suspected cervical spine injury because it minimizes movement
of the cervical spine. The head-tilt/chin-lift maneuver may exacerbate spinal cord injury
by extending the neck. Manual in-line stabilization should accompany any airway
maneuver in suspected spinal injury, but the jaw-thrust itself is the foundational
technique.
Question 3: A 65-year-old male presents with crushing substernal chest pain,
diaphoresis, and nausea. His vital signs are BP 90/60, P 110, R 24. What is the EMT's
highest priority intervention?
A. Administer aspirin 324 mg chewable
B. Apply high-flow oxygen via non-rebreather mask
C. Assist with prescribed nitroglycerin
D. Prepare for immediate transport
,CORRECT ANSWER: D. Prepare for immediate transport
RATIONALE: While administering aspirin, oxygen, and assisting with nitroglycerin are
important interventions for suspected acute coronary syndrome, the patient's
hypotension (BP 90/60) and tachycardia indicate possible cardiogenic shock. The
highest priority is rapid transport to a facility capable of definitive cardiac care, as
delays increase mortality. Interventions should occur en route when possible, but
transport initiation takes precedence in unstable patients.
Question 4: Which sign is most indicative of adequate ventilation when using a bag-
valve-mask device on an adult patient?
A. Chest rise with each ventilation
B. Audible breath sounds bilaterally
C. Oxygen saturation above 94%
D. Decreased heart rate after ventilation
CORRECT ANSWER: A. Chest rise with each ventilation
RATIONALE: Visible chest rise is the most immediate and reliable indicator that
ventilations are effectively delivering air to the lungs. While breath sounds, oxygen
saturation, and heart rate changes provide useful information, they are secondary
indicators that may be delayed or influenced by other factors. EMTs are trained to
observe chest rise as the primary feedback for adequate bag-valve-mask ventilation
technique.
Question 5: What is the normal respiratory rate range for an adult patient?
A. 8-12 breaths per minute
B. 12-20 breaths per minute
C. 20-30 breaths per minute
D. 30-40 breaths per minute
CORRECT ANSWER: B. 12-20 breaths per minute
RATIONALE: The accepted normal respiratory rate for adults is 12-20 breaths per
minute. Rates below 12 may indicate respiratory depression, while rates above 20 may
suggest respiratory distress or compensation for metabolic acidosis. EMTs must
recognize deviations from this range as potential indicators of underlying pathology
requiring intervention.
Question 6: Which of the following is a contraindication for administering oral
glucose to a diabetic patient?
A. Blood glucose level of 60 mg/dL
B. Patient is alert and able to swallow
C. Patient is unconscious or has altered mental status
D. Patient reports feeling shaky and diaphoretic
CORRECT ANSWER: C. Patient is unconscious or has altered mental status
,RATIONALE: Oral glucose should never be administered to patients who are
unconscious or have altered mental status due to the risk of aspiration. These patients
require advanced airway management and intravenous dextrose, which are beyond the
EMT-B scope. Oral glucose is only appropriate for conscious, alert patients who can
safely swallow and protect their airway.
Question 7: What is the primary purpose of the SAMPLE history in patient
assessment?
A. To determine the patient's insurance information
B. To gather focused information about the patient's condition
C. To document the scene safety assessment
D. To calculate medication dosages
CORRECT ANSWER: B. To gather focused information about the patient's condition
RATIONALE: SAMPLE (Signs/Symptoms, Allergies, Medications, Past medical history,
Last oral intake, Events leading to illness/injury) is a mnemonic used during the
secondary assessment to systematically gather relevant patient history. This
information helps identify potential causes of the patient's condition, contraindications
to treatment, and factors affecting care decisions.
Question 8: Which of the following best describes the mechanism of injury in a
patient who was the unrestrained driver in a frontal collision?
A. Blunt force trauma to the anterior chest
B. Penetrating trauma from broken glass
C. Hyperextension injury to the cervical spine
D. Compression injury to the lower extremities
CORRECT ANSWER: A. Blunt force trauma to the anterior chest
RATIONALE: In a frontal collision, an unrestrained driver continues moving forward until
striking the steering wheel, dashboard, or windshield, resulting in blunt force trauma to
the anterior chest, head, and abdomen. While cervical spine injuries and lower
extremity trauma may also occur, the primary mechanism involves blunt impact to the
front of the body. EMTs must anticipate internal injuries even without external signs.
Question 9: What is the appropriate suction time limit for an adult patient when
clearing the airway?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
CORRECT ANSWER: C. 15 seconds
RATIONALE: Suctioning should be limited to 15 seconds for adults to prevent hypoxia,
as prolonged suctioning removes oxygen from the airway and can cause bradycardia or
, cardiac arrest. For pediatric and infant patients, the limit is 10 and 5 seconds
respectively. EMTs should pre-oxygenate when possible and monitor the patient's
condition during suctioning procedures.
Question 10: Which of the following is a sign of compensated shock in an adult
patient?
A. Hypotension
B. Altered mental status
C. Tachycardia with normal blood pressure
D. Absent peripheral pulses
CORRECT ANSWER: C. Tachycardia with normal blood pressure
RATIONALE: Compensated shock is characterized by the body's physiological
mechanisms maintaining blood pressure despite inadequate perfusion. Tachycardia is
an early compensatory response to maintain cardiac output. Hypotension, altered
mental status, and absent pulses indicate decompensated shock, representing a later,
more critical stage requiring immediate advanced intervention.
Question 11: What is the correct compression-to-ventilation ratio for two-rescuer
CPR on an adult patient?
A. 15:2
B. 30:2
C. 5:1
D. 10:1
CORRECT ANSWER: B. 30:2
RATIONALE: Current AHA guidelines specify a 30:2 compression-to-ventilation ratio for
adult CPR regardless of the number of rescuers. This ratio optimizes blood flow while
providing adequate ventilation. For infant and child two-rescuer CPR, the ratio is 15:2,
but adult protocols uniformly use 30:2 to minimize interruptions in chest compressions.
Question 12: Which of the following medications is within the EMT-B scope of
practice to assist a patient in administering?
A. Epinephrine via auto-injector for anaphylaxis
B. Albuterol via nebulizer for asthma
C. Nitroglycerin for chest pain
D. Both A and C
CORRECT ANSWER: D. Both A and C
RATIONALE: EMT-Basic providers may assist patients with administering their
prescribed epinephrine auto-injectors for anaphylaxis and nitroglycerin for cardiac
chest pain. Administering albuterol via nebulizer typically requires advanced
certification (EMT-Intermediate or Paramedic) in most jurisdictions, though some states
