Preparation Guide
Question 1: Which of the following medications administered by an EMT-
Intermediate is primarily indicated for the treatment of symptomatic bradycardia?
A. Adenosine
B. Atropine sulfate
C. Amiodarone
D. Magnesium sulfate
CORRECT ANSWER: B. Atropine sulfate
RATIONALE: Atropine sulfate is an anticholinergic agent that blocks vagal stimulation of
the heart, increasing heart rate. It is the first-line medication for symptomatic
bradycardia in the EMT-Intermediate scope of practice. Adenosine is used for
supraventricular tachycardia, amiodarone for ventricular arrhythmias, and magnesium
sulfate for torsades de pointes or eclampsia.
Question 2: When establishing intravenous access in a hypovolemic patient, which
catheter gauge is MOST appropriate for rapid fluid resuscitation?
A. 24-gauge
B. 22-gauge
C. 20-gauge
D. 14-gauge
CORRECT ANSWER: D. 14-gauge
RATIONALE: Larger-bore catheters (smaller gauge numbers) allow for greater fluid flow
rates according to Poiseuille's law. A 14-gauge catheter provides the highest flow rate
for rapid volume expansion in hypovolemic patients. Smaller gauges (20-24) are
appropriate for medication administration or pediatric patients but insufficient for
aggressive resuscitation.
Question 3: An EMT-Intermediate is preparing to administer epinephrine 1:1,000 for
anaphylaxis. Which route is MOST appropriate for initial administration in a patient
with severe respiratory distress?
A. Intravenous push
B. Intramuscular injection
C. Subcutaneous injection
D. Endotracheal instillation
CORRECT ANSWER: B. Intramuscular injection
,RATIONALE: Intramuscular injection into the anterolateral thigh provides rapid
absorption of epinephrine for anaphylaxis and is the recommended first-line route. IV
administration carries higher risk of adverse cardiac effects and is typically reserved for
refractory cases under medical control. Subcutaneous absorption is slower, and
endotracheal administration is unreliable for epinephrine.
Question 4: During cardiac monitoring, an EMT-Intermediate identifies a rhythm
with no visible P waves, irregularly irregular R-R intervals, and a ventricular rate of
110 bpm. This rhythm is BEST described as:
A. Sinus tachycardia
B. Atrial flutter
C. Atrial fibrillation
D. Ventricular tachycardia
CORRECT ANSWER: C. Atrial fibrillation
RATIONALE: Atrial fibrillation is characterized by absent P waves, an irregularly irregular
ventricular response, and variable R-R intervals due to chaotic atrial electrical activity.
Sinus tachycardia has visible P waves before each QRS. Atrial flutter shows sawtooth
flutter waves. Ventricular tachycardia demonstrates wide QRS complexes without
preceding P waves.
Question 5: Which of the following is a CONTRAINDICATION to the administration
of nitroglycerin by an EMT-Intermediate?
A. Systolic blood pressure of 110 mmHg
B. Patient reports headache after previous dose
C. Recent use of sildenafil (Viagra) within 24 hours
D. History of coronary artery disease
CORRECT ANSWER: C. Recent use of sildenafil (Viagra) within 24 hours
RATIONALE: Phosphodiesterase-5 inhibitors like sildenafil, tadalafil, or vardenafil
potentiate the vasodilatory effects of nitroglycerin, potentially causing life-threatening
hypotension. This combination is an absolute contraindication. Mild hypotension (SBP
>90-100 mmHg), headache, or CAD history are not contraindications when nitroglycerin
is otherwise indicated.
Question 6: When performing endotracheal intubation, the EMT-Intermediate
confirms tube placement by all of the following EXCEPT:
A. Direct visualization of the tube passing through the vocal cords
B. Bilateral chest rise and fall with ventilation
C. Presence of end-tidal CO2 waveform on capnography
D. Gastric distension observed after ventilation
CORRECT ANSWER: D. Gastric distension observed after ventilation
,RATIONALE: Gastric distension indicates esophageal intubation, which is a
complication requiring immediate tube removal and reattempt. Proper confirmation
includes direct visualization, bilateral chest rise, equal breath sounds, absence of
epigastric sounds, and quantitative waveform capnography—the gold standard for
confirming tracheal placement.
Question 7: An EMT-Intermediate is caring for a patient with suspected tension
pneumothorax. Which clinical finding is MOST indicative of this life-threatening
condition?
A. Decreased breath sounds on the affected side
B. Tracheal deviation away from the affected side
C. Hyperresonance to percussion on the affected side
D. All of the above
CORRECT ANSWER: D. All of the above
RATIONALE: Tension pneumothorax presents with the classic triad: decreased/absent
breath sounds, hyperresonance to percussion, and tracheal deviation away from the
affected side due to mediastinal shift. Additional signs include hypotension, jugular
venous distension, and respiratory distress. Immediate needle decompression is
required.
Question 8: Which of the following IV fluids is considered ISOTONIC and is MOST
commonly used for initial volume expansion in trauma patients?
A. 0.45% sodium chloride
B. 5% dextrose in water (D5W)
C. Lactated Ringer's solution
D. 3% sodium chloride
CORRECT ANSWER: C. Lactated Ringer's solution
RATIONALE: Lactated Ringer's and 0.9% normal saline are isotonic crystalloids that
remain primarily in the intravascular space, making them ideal for volume resuscitation.
D5W becomes hypotonic after dextrose metabolism. 0.45% NaCl is hypotonic, and 3%
NaCl is hypertonic—used for specific indications like severe hyponatremia or cerebral
edema.
Question 9: During assessment of a pediatric patient, the EMT-Intermediate uses
the Pediatric Assessment Triangle. 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 has three components: Appearance
(tone, interactiveness, consolability, look/gaze, speech/cry), Work of Breathing
(retractions, nasal flaring, grunting, abnormal sounds), and Circulation to Skin (pallor,
mottling, cyanosis). This rapid tool identifies physiologic instability without hands-on
assessment.
Question 10: An EMT-Intermediate administers albuterol via nebulizer to a patient
with acute asthma exacerbation. Which parameter should be monitored MOST
closely after administration?
A. Blood glucose level
B. Heart rate and rhythm
C. Pupillary response
D. Capillary refill time
CORRECT ANSWER: B. Heart rate and rhythm
RATIONALE: Albuterol is a beta-2 agonist that can cause tachycardia, palpitations, and
dysrhythmias due to beta-1 cross-stimulation. Monitoring heart rate and rhythm is
essential post-administration. While tremors and anxiety may occur, cardiac effects
pose the greatest immediate risk requiring intervention.
Question 11: Which of the following is the PRIMARY indication for administering
intravenous dextrose (D50) in the prehospital setting?
A. Hyperglycemia with ketonuria
B. Hypoglycemia with altered mental status
C. Diabetic ketoacidosis
D. Hyperosmolar hyperglycemic state
CORRECT ANSWER: B. Hypoglycemia with altered mental status
RATIONALE: D50 (50% dextrose) is indicated for symptomatic hypoglycemia,
particularly when the patient cannot protect their airway or swallow safely. It rapidly
raises blood glucose levels. Hyperglycemic emergencies require fluid resuscitation and
insulin, not dextrose, which would worsen the condition.
Question 12: When interpreting a 12-lead ECG, the EMT-Intermediate identifies ST-
segment elevation in leads II, III, and aVF. This finding suggests ischemia in which
cardiac region?
A. Anterior wall
B. Lateral wall
C. Inferior wall
D. Septal wall
CORRECT ANSWER: C. Inferior wall
RATIONALE: Leads II, III, and aVF view the inferior surface of the heart, supplied
primarily by the right coronary artery. ST-elevation in these leads indicates acute inferior
