Question 1. A 68-year-old male presents with sudden onset of slurred speech, right-
sided facial droop, and left arm weakness. Symptoms began 45 minutes ago. Which
intervention is MOST critical during prehospital care?
A. Administer aspirin 324 mg orally
B. Perform a Cincinnati Prehospital Stroke Scale assessment
C. Transport rapidly to a stroke center while monitoring airway
D. Obtain a detailed history of prior strokes
Correct Answer: C
Rationale: Time is brain in acute stroke management. Rapid transport to a designated
stroke center is the highest priority to enable timely administration of thrombolytics or
endovascular therapy . While stroke scale assessment (B) is important for recognition, it
should not delay transport. Aspirin administration (A) is contraindicated until
hemorrhagic stroke is ruled out by imaging . A detailed history (D) can be obtained en
route.
Question 2. During assessment of a trauma patient, you note distended neck veins,
muffled heart sounds, and hypotension. This triad is MOST suggestive of:
A. Tension pneumothorax
B. Cardiac tamponade
C. Massive hemothorax
D. Neurogenic shock
Correct Answer: B
,Rationale: Beck's triad—distended neck veins, muffled heart sounds, and hypotension—
is classically associated with cardiac tamponade, where fluid accumulates in the
pericardial sac, impairing cardiac filling . Tension pneumothorax (A) may cause JVD and
hypotension but typically presents with tracheal deviation and unilateral breath sounds.
Neurogenic shock (D) presents with hypotension and bradycardia without JVD .
Question 3. Which of the following findings indicates a condition where air is trapped in
the lower airways?
A. Rhonchi
B. Rales
C. Wheezes
D. Pleural rub
Correct Answer: C
Rationale: Wheezes are caused by airflow through narrowed lower airways (terminal
bronchioles) in asthma, which traps air in the alveoli . Rhonchi (A) are caused by airflow
over congestion/secretions in larger airways. Rales (B) are caused by alveoli reinflating in
congestive heart failure. A pleural rub (D) is caused by the pleural lining rubbing
together when there is inflammation .
Question 4. A 25-year-old male complains of shortness of breath over the past four
hours after playing soccer. His chest expansion is normal and he has no chest wall pain.
You hear diminished breath sounds over his right upper thorax. His vital signs are P 106,
R 18, BP 126/84, and SpO2 is 92% on room air. What is the most likely diagnosis?
A. Spontaneous pneumothorax
B. Pulmonary embolism
C. Costochondritis
D. Pleuritis
Correct Answer: A
Rationale: This patient most likely suffered a spontaneous pneumothorax. Exertion
during exercise in a young male (likely thin in body structure) causing diminished breath
,sounds on one side are the key clues . A pulmonary embolism (B) is unlikely in a young
person exercising. Costochondritis (C) presents with chest wall pain. Pleuritis (D)
presents with chest pain that dissipates when the patient holds their breath .
Question 5. A 2-year-old female who has had a cold for the past two days now has
frequent barking cough. Her skin is warm to touch. She has inspiratory stridor, and her
SpO2 is 98% on room air. When transporting her, you should prepare for:
A. Emesis
B. Respiratory arrest
C. Sepsis
D. Airway obstruction
Correct Answer: D
Rationale: Barking cough and inspiratory stridor in a child with a recent cold are classic
signs of croup (laryngotracheobronchitis). The child is at risk for airway obstruction from
subglottic swelling . While emesis (A) and respiratory arrest (B) are possible, the primary
concern is progressive airway compromise. Sepsis (C) is not the primary concern.
Question 6. A patient with a history of COPD presents with increased dyspnea, pursed-
lip breathing, and a respiratory rate of 28/min. Oxygen saturation is 88% on room air.
What is the MOST appropriate oxygen therapy?
A. High-flow oxygen via non-rebreather mask at 15 L/min
B. Nasal cannula at 2-4 L/min titrated to SpO2 88-92%
C. Bag-valve-mask ventilation with 100% oxygen
D. Withhold oxygen due to risk of suppressing hypoxic drive
Correct Answer: B
Rationale: For COPD patients, oxygen should be titrated to a target SpO2 of 88-92% to
avoid suppressing the hypoxic drive . High-flow oxygen (A) can cause respiratory
depression in these patients. BVM ventilation (C) is not indicated as the patient is
breathing spontaneously. Withholding oxygen (D) is inappropriate as the patient is
hypoxemic .
, Question 7. Which of the following is the MOST appropriate initial action when
managing a patient with suspected tension pneumothorax?
A. Administer high-flow oxygen via non-rebreather mask
B. Perform needle decompression at the 2nd intercostal space, midclavicular line
C. Apply a chest seal to the affected side
D. Assist ventilations with a bag-valve-mask device
Correct Answer: B
Rationale: Tension pneumothorax is a life-threatening condition requiring immediate
intervention. Needle decompression at the 2nd intercostal space, midclavicular line on
the affected side is the definitive prehospital treatment to relieve intrathoracic pressure .
While oxygen (A) and ventilation support (D) are important, they do not address the
underlying pathophysiology. Chest seals (C) are indicated for open pneumothorax, not
tension pneumothorax .
Question 8. Which medication is within the EMT scope of practice for administration to
a patient experiencing anaphylaxis?
A. Diphenhydramine 25 mg IV
B. Albuterol 2.5 mg via nebulizer
C. Epinephrine via auto-injector
D. Methylprednisolone 125 mg IV
Correct Answer: C
Rationale: EMTs are authorized to assist patients with or administer epinephrine via
auto-injector for anaphylaxis per most state protocols . Epinephrine is the first-line
treatment for anaphylaxis, reversing bronchospasm, vasodilation, and increased vascular
permeability . Antihistamines (A), bronchodilators (B), and steroids (D) are adjuncts but
not first-line and are often outside EMT scope .
