Fisdap EMT Comprehensive Exam With Correct Answers
(2026/2027)
1. You are treating a 68-year-old male who is complaining of a sudden onset of sharp, tearing
chest pain that radiates directly to his back between the shoulder blades. His blood
pressure in the right arm is 160/90 mmHg, while the blood pressure in the left arm is
130/70 mmHg. He has a history of hypertension. Based on these specific clinical findings,
what life-threatening condition do you suspect, and what is the primary physiological
reason for the blood pressure discrepancy?
Answer: The clinical presentation of "tearing" pain radiating to the back, combined with a
significant blood pressure differential between the arms, is classic for an Aortic Dissection.
This occurs when the inner layer of the aorta (the intima) tears, allowing blood to flow
between the layers of the aortic wall. The blood pressure discrepancy occurs because the
dissection flap can physically obstruct or limit blood flow into one of the subclavian arteries,
leading to a lower pressure reading in the affected arm.
Correct Answer: Aortic Dissection; caused by a tear in the aortic intima obstructing branch
vessels.
2. A 24-year-old female was involved in a high-speed motor vehicle collision. She is conscious
but restless and complaining of difficulty breathing. On assessment, you note diminished
breath sounds on the right side, jugular vein distention (JVD), and tracheal deviation
toward the left. Her skin is cool and clammy, and her blood pressure is 88/50 mmHg.
Describe the definitive pathophysiology of this condition and the immediate intervention
required by the EMT.
Answer: The patient is suffering from a Tension Pneumothorax. This occurs when a one-way
valve is created by an injury to the lung; air enters the pleural space during inhalation but
cannot escape. This builds massive intrathoracic pressure, collapsing the lung and shifting
the mediastinum (causing tracheal deviation). The high pressure compresses the superior
and inferior vena cava, which prevents venous return to the heart and leads to obstructive
shock. The EMT must immediately provide high-flow oxygen and rapid transport, notifying
ALS for needle decompression.
Correct Answer: Tension Pneumothorax; obstructive shock caused by intrathoracic
pressure and decreased venous return.
3. You respond to a "person down" and find a 50-year-old male who is unresponsive,
pulseless, and apneic. A bystander states the patient collapsed 4 minutes ago. You and
your partner begin high-quality CPR. Once the AED is attached, it advises "No Shock
Advised." The monitor shows an organized rhythm, but the patient still has no palpable
pulse. What is this rhythm called, and what is the EMT’s priority in managing this patient?
Answer: This rhythm is known as Pulseless Electrical Activity (PEA). It means the heart’s
electrical system is firing, but the cardiac muscle is failing to produce a mechanical
contraction. The priority for the EMT is to continue high-quality chest compressions with
minimal interruptions and attempt to identify reversible causes while providing ventilations.
Correct Answer: Pulseless Electrical Activity (PEA); priority is uninterrupted high-quality
CPR.
4. A 72-year-old female is found in bed. She is pale, diaphoretic, and has rales (crackles)
audible in the bases of both lungs. She is struggling to breathe and has a blood pressure of
180/100 mmHg. She has a history of "heart failure." Explain the underlying cause of the
, rales and the physiological benefit of applying Continuous Positive Airway Pressure (CPAP)
to this patient.
Answer: The patient is in Left-Sided Heart Failure (Congestive Heart Failure/Pulmonary
Edema). The left ventricle fails to pump blood effectively, causing blood to back up into the
pulmonary veins. This pressure forces fluid out of the capillaries and into the alveoli, creating
the "rales" sound. CPAP provides constant pressure that helps "push" the fluid out of the
alveoli back into the vasculature and keeps the alveoli open, improving gas exchange.
Correct Answer: Pulmonary Edema; CPAP forces interstitial fluid back into the pulmonary
capillaries.
5. You are treating a 19-year-old male who was stung by a bee. He has hives, a swollen
tongue, and is wheezing. His blood pressure is 80/40 mmHg. Explain the difference
between an allergic reaction and anaphylaxis in this context, and describe the primary
pharmacological action of Epinephrine on the beta-2 receptors in the lungs.
Answer: An allergic reaction is a local or mild systemic immune response,
whereas Anaphylaxis is a life-threatening, multi-systemic reaction characterized by
respiratory distress and cardiovascular collapse (hypotension). This patient is in anaphylactic
shock. Epinephrine acts on beta-2 receptors in the lungs to cause bronchodilation, which
opens the narrowed airways and improves ventilation.
Correct Answer: Anaphylaxis; Beta-2 stimulation causes bronchodilation to relieve
respiratory distress.
6. A 30-year-old male has been pulled from a house fire. He has soot around his nose and
mouth, and his voice is hoarse. His SpO2 is 99% on room air, but he is confused and
complaining of a headache. Explain why the SpO2 reading may be dangerously misleading
in this patient and identify the most likely underlying condition.
Answer: The patient is likely suffering from Carbon Monoxide (CO) Poisoning. Carbon
monoxide has an affinity for hemoglobin over 200 times greater than oxygen. Standard pulse
oximetry cannot distinguish between oxyhemoglobin and carboxyhemoglobin; it simply
measures saturated hemoglobin. Therefore, the monitor reads 99% even though the
hemoglobin is saturated with CO rather than oxygen.
Correct Answer: Carbon Monoxide poisoning; SpO2 cannot distinguish between oxygen
and CO on hemoglobin.
7. A 45-year-old male is found in a garage with an altered mental status. His skin is hot and
dry to the touch, and his heart rate is 130 bpm. He is no longer sweating. What is the
specific heat-related emergency occurring, and why is the lack of sweating a critical clinical
sign?
Answer: The patient is suffering from Heat Stroke, the most severe heat-related emergency.
The lack of sweating (anhidrosis) is a critical sign because it indicates that the body's
thermoregulatory mechanisms have completely failed. The core temperature rises rapidly,
leading to brain damage and multi-organ failure. Immediate cooling and rapid transport are
required.
Correct Answer: Heat Stroke; represents a total failure of the body’s
cooling/thermoregulatory systems.
8. A 60-year-old male complains of chest pressure that started while he was mowing the
lawn. He took one of his own nitroglycerin tablets, and the pain went away after 5 minutes
of rest. He describes this as a "normal" occurrence for him. What is the name of this
