Questions
Question 1: Which of the following is the MOST appropriate initial airway
management technique for an unconscious adult patient with inadequate
breathing and suspected cervical spine injury?
A. Head-tilt/chin-lift maneuver
B. Jaw-thrust maneuver without head extension
C. Insertion of a nasopharyngeal airway alone
D. Immediate endotracheal intubation
CORRECT ANSWER: B. Jaw-thrust maneuver without head extension
Rationale: The jaw-thrust maneuver without head extension is the preferred initial
airway technique for patients with suspected cervical spine injury because it minimizes
movement of the cervical vertebrae while effectively opening the airway. The head-
tilt/chin-lift may exacerbate spinal injury, while adjuncts or advanced airways are
considered after basic maneuvers fail or are insufficient.
Question 2: An EMT-I is preparing to administer a medication via the intramuscular
route. Which anatomical site is MOST appropriate for an adult patient requiring
epinephrine for anaphylaxis?
A. Deltoid muscle
B. Vastus lateralis muscle
C. Ventrogluteal muscle
D. Rectus femoris muscle
CORRECT ANSWER: B. Vastus lateralis muscle
Rationale: The vastus lateralis muscle is the preferred site for intramuscular
epinephrine administration in adults during anaphylaxis due to its large muscle mass,
consistent absorption rate, and distance from major nerves and blood vessels. While
other sites are acceptable for IM injections, the vastus lateralis is specifically
recommended in emergency anaphylaxis protocols for rapid, reliable drug delivery.
Question 3: During assessment of a patient with chest pain, the EMT-I obtains a 12-
lead ECG. Which ECG finding is MOST indicative of acute myocardial injury?
A. ST-segment depression in multiple leads
B. T-wave inversion in lead III only
C. ST-segment elevation in two contiguous leads
D. Prolonged QT interval
,CORRECT ANSWER: C. ST-segment elevation in two contiguous leads
Rationale: ST-segment elevation in two or more contiguous leads on a 12-lead ECG is
the hallmark finding of acute myocardial injury, specifically ST-elevation myocardial
infarction (STEMI). This finding warrants immediate activation of the cardiac
catheterization team. ST depression suggests ischemia, isolated T-wave changes are
nonspecific, and QT prolongation relates to repolarization abnormalities, not acute
injury.
Question 4: Which of the following medications is within the typical EMT-I scope of
practice for administration to a patient experiencing acute bronchospasm?
A. Ipratropium bromide
B. Albuterol sulfate
C. Methylprednisolone
D. Theophylline
CORRECT ANSWER: B. Albuterol sulfate
Rationale: Albuterol sulfate, a short-acting beta-2 agonist, is commonly included in the
EMT-I formulary for management of acute bronchospasm associated with asthma or
COPD exacerbations. Ipratropium may be used in some systems but is less universally
authorized; corticosteroids and theophylline are typically outside the EMT-I scope due
to administration complexity and delayed onset.
Question 5: A patient presents with signs of hypovolemic shock following a motor
vehicle collision. Which intervention should the EMT-I prioritize AFTER controlling
external hemorrhage?
A. Administer high-flow oxygen
B. Initiate rapid intravenous fluid resuscitation
C. Apply a pneumatic antishock garment
D. Elevate the lower extremities 12 inches
CORRECT ANSWER: A. Administer high-flow oxygen
Rationale: After controlling life-threatening external hemorrhage, the next priority in
hypovolemic shock management is to optimize oxygenation and ventilation. High-flow
oxygen helps compensate for reduced tissue perfusion by maximizing oxygen content in
the remaining blood volume. IV fluid resuscitation is important but follows airway and
breathing interventions per the ABCs; PASG use is largely outdated, and leg elevation
has limited evidence and may compromise respiratory effort.
Question 6: When establishing intravenous access in an adult patient, which vein is
considered the FIRST choice for cannulation by an EMT-I?
A. Cephalic vein
B. Basilic vein
,C. Median cubital vein
D. Dorsal hand veins
CORRECT ANSWER: C. Median cubital vein
Rationale: The median cubital vein, located in the antecubital fossa, is the preferred
initial site for IV cannulation due to its large size, superficial location, stability, and lower
risk of complications compared to other veins. Cephalic and basilic veins are
acceptable alternatives, while dorsal hand veins are smaller, more painful, and prone to
infiltration, making them less ideal for emergency access.
Question 7: Which of the following clinical findings is MOST consistent with
neurogenic shock rather than hypovolemic shock?
A. Tachycardia and cool, clammy skin
B. Bradycardia and warm, dry skin
C. Hypotension with delayed capillary refill
D. Tachypnea and decreased level of consciousness
CORRECT ANSWER: B. Bradycardia and warm, dry skin
Rationale: Neurogenic shock, resulting from spinal cord injury, typically presents with
hypotension accompanied by bradycardia and warm, dry skin due to loss of
sympathetic tone and unopposed parasympathetic activity. Hypovolemic shock
characteristically causes tachycardia and cool, clammy skin from compensatory
sympathetic activation. Recognizing this distinction guides appropriate management,
including cautious fluid administration and potential vasopressor consideration.
Question 8: An EMT-I is caring for a pediatric patient in respiratory distress. Which
assessment finding indicates the MOST severe compromise requiring immediate
advanced airway intervention?
A. Nasal flaring and intercostal retractions
B. Grunting and head bobbing
C. Cyanosis and decreased level of consciousness
D. Tachypnea with wheezing on auscultation
CORRECT ANSWER: C. Cyanosis and decreased level of consciousness
Rationale: Cyanosis combined with altered mental status signifies severe hypoxia and
impending respiratory failure, necessitating immediate advanced airway management.
While nasal flaring, retractions, grunting, and head bobbing indicate increased work of
breathing, they represent earlier stages of distress. Wheezing suggests bronchospasm
but does not alone indicate failure; cyanosis with lethargy or unresponsiveness is a
critical red flag.
Question 9: Which of the following is a CONTRAINDICATION to the administration
of nitroglycerin by an EMT-I?
, A. Systolic blood pressure of 110 mmHg
B. Patient report of headache
C. Recent use of phosphodiesterase-5 inhibitors (e.g., sildenafil)
D. History of myocardial infarction
CORRECT ANSWER: C. Recent use of phosphodiesterase-5 inhibitors (e.g.,
sildenafil)
Rationale: Nitroglycerin is contraindicated in patients who have used
phosphodiesterase-5 inhibitors (such as sildenafil, tadalafil, or vardenafil) within the
past 24–48 hours due to the risk of profound, life-threatening hypotension from
synergistic vasodilation. A systolic BP of 110 mmHg is generally acceptable (unless
below protocol threshold, often 90–100 mmHg), headache is a common side effect, and
prior MI is an indication, not contraindication, for nitroglycerin in acute chest pain.
Question 10: During transport of a patient with suspected acute stroke, which
intervention is MOST critical for the EMT-I to perform?
A. Administer aspirin 325 mg orally
B. Maintain oxygen saturation ≥94%
C. Lower the head of the stretcher to increase cerebral perfusion
D. Obtain a full 12-lead ECG
CORRECT ANSWER: B. Maintain oxygen saturation ≥94%
Rationale: Maintaining adequate oxygenation (SpO₂ ≥94%) is critical in acute stroke
care to prevent secondary brain injury from hypoxia. Aspirin administration is typically
deferred until hemorrhagic stroke is ruled out by imaging. Elevating the head (not
lowering) is often recommended to reduce intracranial pressure, and while ECG
acquisition may identify comorbidities, it is secondary to ensuring oxygenation and
rapid transport to a stroke center.
Question 11: Which of the following best describes the mechanism of action of
naloxone when administered for suspected opioid overdose?
A. Agonist at mu-opioid receptors
B. Competitive antagonist at opioid receptors
C. Inhibitor of acetylcholinesterase
D. Stimulator of respiratory center in the medulla
CORRECT ANSWER: B. Competitive antagonist at opioid receptors
Rationale: Naloxone is a competitive antagonist at mu-opioid receptors, displacing
opioids and reversing their effects, particularly respiratory depression. It does not
activate receptors (agonist), affect acetylcholine metabolism, or directly stimulate the
respiratory center; its action is purely antagonistic, making it safe and specific for opioid
reversal without intrinsic activity.
