Courses and Recertification Exams on the First Attempt
Question 1: Which of the following is the preferred initial method for opening the airway of
an unconscious trauma patient with suspected cervical spine injury?
A. Head-tilt/chin-lift maneuver
B. Jaw-thrust maneuver
C. Modified head-tilt/neck-lift
D. Finger sweep technique
CORRECT ANSWER: B. Jaw-thrust maneuver
Rationale: The jaw-thrust maneuver is the preferred method for opening the airway in trauma
patients with suspected cervical spine injury because it minimizes movement of the cervical
spine while effectively lifting the tongue away from the posterior pharynx. The head-tilt/chin-
lift may exacerbate spinal injury and should be avoided when cervical spine trauma is
suspected.
Question 2: During assessment of an adult patient, you note agonal respirations at a rate of 6
breaths per minute. What is the most appropriate immediate intervention?
A. Apply a non-rebreather mask at 15 L/min
B. Begin positive pressure ventilation with a bag-valve mask
C. Administer oral glucose and reassess
D. Place the patient in the recovery position and monitor
CORRECT ANSWER: B. Begin positive pressure ventilation with a bag-valve mask
Rationale: Agonal respirations are inadequate and indicate respiratory failure. A rate of 6
breaths per minute is insufficient for adequate gas exchange. Immediate positive pressure
ventilation with a bag-valve mask and supplemental oxygen is required to support oxygenation
and ventilation until advanced care arrives or the patient improves.
,Question 3: A 68-year-old male presents with sudden onset of slurred speech, right-sided
facial droop, and left arm weakness. His symptoms began 45 minutes ago. Which condition
should the EMT suspect FIRST?
A. Hypoglycemia
B. Transient ischemic attack
C. Acute ischemic stroke
D. Bell's palsy
CORRECT ANSWER: C. Acute ischemic stroke
Rationale: The sudden onset of focal neurological deficits (slurred speech, facial droop,
unilateral weakness) within a known timeframe is highly suggestive of an acute ischemic stroke.
Rapid recognition and transport to a stroke center are critical, as thrombolytic therapy may be
time-sensitive. While hypoglycemia can mimic stroke, it should be ruled out with a blood
glucose check, but the presentation strongly favors stroke.
Question 4: When administering oxygen via a nasal cannula, what is the maximum
recommended flow rate to avoid mucosal drying and patient discomfort?
A. 2 L/min
B. 4 L/min
C. 6 L/min
D. 8 L/min
CORRECT ANSWER: C. 6 L/min
Rationale: The maximum recommended flow rate for a nasal cannula is 6 L/min. Flow rates
higher than this do not significantly increase FiO2 and can cause nasal mucosa drying, epistaxis,
and patient discomfort. For higher oxygen concentrations, a simple face mask or non-
rebreather mask should be used.
Question 5: Which of the following signs is MOST indicative of compensated shock in an adult
patient?
A. Hypotension with bradycardia
B. Tachycardia with normal blood pressure
C. Unresponsiveness with cyanosis
D. Warm, dry skin with bounding pulses
CORRECT ANSWER: B. Tachycardia with normal blood pressure
Rationale: In compensated shock, the body maintains blood pressure through sympathetic
nervous system activation, resulting in tachycardia, peripheral vasoconstriction, and normal or
near-normal blood pressure. Hypotension is a late sign of decompensated shock. Recognizing
compensated shock allows for earlier intervention and improved outcomes.
,Question 6: A patient with a known history of asthma presents with severe shortness of
breath, wheezing, and inability to speak in full sentences. After administering high-flow
oxygen, what is the NEXT most appropriate intervention?
A. Assist the patient with their prescribed albuterol inhaler
B. Administer epinephrine 1:1,000 intramuscularly
C. Apply a continuous positive airway pressure (CPAP) device
D. Begin rapid transport without further intervention
CORRECT ANSWER: A. Assist the patient with their prescribed albuterol inhaler
Rationale: For a patient experiencing an acute asthma exacerbation, assisting with their
prescribed short-acting beta-agonist (e.g., albuterol) via metered-dose inhaler or nebulizer is
the standard prehospital intervention after ensuring adequate oxygenation. Epinephrine may
be considered in severe cases per protocol, but assisting with the patient's own bronchodilator
is first-line. CPAP is generally reserved for cardiogenic pulmonary edema.
Question 7: Which of the following is the MOST reliable indicator of effective chest
compressions during CPR?
A. Palpable carotid pulse with each compression
B. Visible chest rise with each ventilation
C. End-tidal CO2 waveform on capnography
D. Patient's skin color improving
CORRECT ANSWER: A. Palpable carotid pulse with each compression
Rationale: While end-tidal CO2 monitoring is valuable in advanced settings, in the basic EMT
scope, the most reliable field indicator of effective chest compressions is the ability to palpate a
carotid pulse with each compression, indicating adequate cardiac output generation. Chest rise
indicates effective ventilation, not compression quality. Skin color changes are late and
unreliable signs.
Question 8: A 45-year-old female complains of crushing substernal chest pain radiating to her
left jaw. She is diaphoretic and nauseated. Vital signs: BP 168/94, P 112, R 24. What is the
EMT's PRIORITY intervention?
A. Administer aspirin 324 mg chewable
B. Apply the AED and analyze rhythm
C. Provide high-flow oxygen via non-rebreather mask
D. Obtain a 12-lead ECG
CORRECT ANSWER: C. Provide high-flow oxygen via non-rebreather mask
Rationale: In a patient with signs and symptoms suggestive of acute coronary syndrome, the
priority is to maximize oxygen delivery to the myocardium. High-flow oxygen via non-
, rebreather mask is indicated for patients with chest pain and signs of hypoxia or respiratory
distress. Aspirin administration is important but follows oxygen therapy. AED application is for
cardiac arrest, not conscious patients. EMTs typically do not obtain 12-lead ECGs.
Question 9: When assessing a pediatric patient using the Pediatric Assessment Triangle (PAT),
which component evaluates the child's work of breathing?
A. Appearance
B. Work of breathing
C. Circulation to skin
D. Disability
CORRECT ANSWER: B. Work of breathing
Rationale: The Pediatric Assessment Triangle consists of three components: Appearance
(mental status, muscle tone, interactiveness), Work of Breathing (effort, sounds, positioning),
and Circulation to Skin (color, pallor, mottling). Work of breathing specifically assesses
respiratory effort through observation of retractions, nasal flaring, grunting, and abnormal
positioning.
Question 10: Which of the following is a contraindication to the use of oral glucose in a
diabetic patient?
A. Blood glucose of 55 mg/dL
B. Patient is alert and able to swallow
C. Patient is unconscious or has a gag reflex impairment
D. Patient reports feeling shaky and diaphoretic
CORRECT ANSWER: C. Patient is unconscious or has a gag reflex impairment
Rationale: Oral glucose should never be administered to a patient who is unconscious, has an
altered mental status with impaired gag reflex, or cannot protect their airway, due to the high
risk of aspiration. In such cases, intramuscular glucagon or intravenous dextrose (by ALS) is
indicated. Alert patients with confirmed hypoglycemia and intact airway reflexes are
appropriate candidates for oral glucose.
Question 11: A patient presents with a severe allergic reaction after a bee sting. He has
stridor, facial swelling, and hypotension. After administering high-flow oxygen, what is the
NEXT critical intervention?
A. Apply a tourniquet proximal to the sting site
B. Assist with epinephrine auto-injector administration
C. Administer diphenhydramine orally
D. Place the patient in Trendelenburg position
CORRECT ANSWER: B. Assist with epinephrine auto-injector administration
