EMT COMPREHENSIVE PRACTICE
EXAM (JBLEARNING 2026/2027)
QUESTIONS AND VERIFIED ANSWERS|
GRADE A+
1. A 68-year-old male presents with acute onset of shortness of breath and pink, frothy
sputum. He has a history of hypertension and two prior myocardial infarctions. His blood
pressure is 190/110 mmHg, pulse is 120 bpm, and SpO2 is 82% on room air. Which
intervention is most appropriate?
A. Apply high-flow oxygen via a non-rebreather mask at 15 L/min.
B. Assist ventilations with a bag-valve mask at a rate of 20 breaths/min.
C. Perform immediate oropharyngeal suctioning to clear the sputum.
D. Initiate Continuous Positive Airway Pressure (CPAP) at 5 cm H2O.
Answer: D
Conceptual Explanation: The patient is exhibiting signs of acute pulmonary edema, likely
due to left-sided heart failure. CPAP is the gold standard for conscious, breathing patients
with pulmonary edema as it increases intrathoracic pressure, pushing fluid out of the
alveoli and improving gas exchange.
2. Which of the following describes the pathophysiology of distributive shock?
A. Widespread vasodilation leading to relative hypovolemia.
,B. Physical obstruction of the great vessels or heart.
C. Loss of intravascular volume leading to decreased preload.
D. Failure of the heart to pump effectively due to muscle damage.
Answer: A
Conceptual Explanation: Distributive shock (e.g., anaphylactic, septic, neurogenic) is
characterized by widespread vasodilation. While the absolute volume of blood is
unchanged, the capacity of the vascular container increases, leading to a drop in blood
pressure and perfusion.
3. A 24-year-old female is found unconscious in an alley. She has pinpoint pupils, a respiratory
rate of 6 breaths/min, and shallow tidal volume. What is the physiological mechanism
causing her respiratory depression?
A. Excessive stimulation of the parasympathetic nervous system.
B. Blockade of acetylcholinesterase at the neuromuscular junction.
C. Binding of exogenous opioids to mu-receptors in the brainstem.
D. Inhibition of the sodium-potassium pump in cardiac myocytes.
Answer: C
Conceptual Explanation: This is a classic presentation of opioid overdose. Opioids bind to
mu-receptors in the central nervous system, specifically the brainstem, which decreases
the respiratory drive and responsiveness to CO2 levels.
, 4. In the pre-hospital setting, what is the most definitive sign of a tension pneumothorax
compared to a simple pneumothorax?
A. Absence of breath sounds on the affected side.
B. Sudden onset of sharp, pleuritic chest pain.
C. Hyperresonance upon percussion of the chest wall.
D. JVD and hemodynamic instability (obstructive shock).
Answer: D
Conceptual Explanation: While both present with decreased breath sounds, a tension
pneumothorax involves increased intrathoracic pressure that shifts the mediastinum,
compresses the vena cava, and leads to Jugular Venous Distension (JVD) and hypotension.
5. A 45-year-old male was involved in a high-speed MVC. He has a BP of 80/40 mmHg, a pulse
of 130 bpm, and skin that is cool, pale, and diaphoretic. His breath sounds are clear and
equal. Which type of shock is most likely?
A. Neurogenic shock
B. Obstructive shock
C. Hypovolemic shock
D. Septic shock
Answer: C
