Introduction
This comprehensive midterm examination is designed to rigorously assess the knowledge, clinical reasoning, and
practical skills of Emergency Medical Technician (EMT) candidates. The exam evaluates mastery of foundational
,theoretical concepts, applied professional knowledge, regulatory compliance, ethical standards, and critical decision-
making in real-world emergency scenarios. Structured as a 200-question multiple-choice assessment, this exam
emphasizes the application of evidence-based protocols, patient safety, and effective communication within the
prehospital setting. Candidates will demonstrate their ability to prioritize interventions, interpret clinical findings, and
execute appropriate treatment plans under pressure. This assessment serves as a critical benchmark for readiness to
provide high-quality, compassionate emergency care.
SECTION ONE: QUESTIONS 1 – 100
1. You are assessing a 45-year-old male who complains of sudden-onset chest pain described as "tearing" that
radiates to his back. He has a history of hypertension and appears pale and diaphoretic. His blood pressure is
180/110 mmHg in the right arm and 100/70 mmHg in the left arm. What is the most likely diagnosis?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
🟢 C. Aortic dissection
🔴 Explanation: Aortic dissection presents with sudden, severe "tearing" chest pain radiating to the back and is
associated with asymmetric blood pressure measurements between arms. This patient's history of hypertension and
,significant blood pressure differential (180/110 vs. 100/70) are classic findings. Myocardial infarction pain is typically
pressure-like, pulmonary embolism causes pleuritic chest pain and hypoxia, and pericarditis pain is positional.
2. What is the correct compression-to-ventilation ratio for a single rescuer performing CPR on an adult cardiac
arrest patient?
A. 30:2
B. 15:2
C. 20:2
D. 30:1
🟢 A. 30:2
🔴 Explanation: The current American Heart Association (AHA) guidelines recommend a compression-to-ventilation
ratio of 30:2 for single-rescuer CPR in adults. This ratio prioritizes continuous chest compressions to maintain
coronary perfusion pressure while providing adequate ventilation. A ratio of 15:2 is used for pediatric patients with
two rescuers.
3. A 68-year-old female presents with confusion, nausea, and vomiting. She has a history of diabetes and takes
metformin. Her skin is warm and flushed, and she has a fruity odor on her breath. Which of the following is the
most likely cause?
A. Hypoglycemia
B. Diabetic ketoacidosis (DKA)
, C. Hyperosmolar hyperglycemic state (HHS)
D. Lactic acidosis
🟢 B. Diabetic ketoacidosis (DKA)
🔴 Explanation: Diabetic ketoacidosis is characterized by hyperglycemia, ketosis, and acidosis, often presenting with
confusion, nausea, vomiting, warm flushed skin, and a fruity (acetone) breath odor. It typically occurs in type 1
diabetes. Hypoglycemia presents with cool, clammy skin. HHS occurs in type 2 diabetes with extreme hyperglycemia
but without significant ketosis. Lactic acidosis can occur with metformin but lacks the fruity breath odor.
4. What is the minimum oxygen flow rate required for a non-rebreather mask to function effectively?
A. 2–4 L/min
B. 5–8 L/min
C. 10–15 L/min
D. 15–20 L/min
🟢 C. 10–15 L/min
🔴 Explanation: A non-rebreather mask requires a flow rate of 10–15 L/min to maintain adequate oxygen
concentration (60–95%) and prevent the reservoir bag from collapsing. This ensures that the patient receives high-
flow oxygen to meet their metabolic demands in conditions like severe hypoxia, trauma, or respiratory failure.
