NREMT EMT - Emergency Medical Technicians (EMT002) Exam

Hemoptysis (coughing up blood) in a physically active person, such as a mountain climber, strongly suggests a pulmonary embolism (PE), particularly due to:

Dehydration

Prolonged exertion or immobility

High altitude increasing clot risk

Symptoms may include:

Shortness of breath

Chest pain

Tachypnea

Hemoptysis

Pulmonary edema generally causes pink frothy sputum and is more associated with heart failure. Neoplasm (lung cancer) is possible but much less acute in onset. Spontaneous pneumothorax causes dyspnea and pleuritic chest pain but not typically hemoptysis.

The correct answer is D. Administer epinephrine auto-injector.

Key findings in this scenario:

Bee sting

Respiratory distress

These findings strongly indicate anaphylaxis, a life-threatening allergic reaction that requires immediate treatment.

Why D is correct:

Epinephrine is the first-line treatment for anaphylaxis because it:

Relieves bronchoconstriction (improves breathing)

Reduces airway swelling

Improves blood pressure

NREMT/AHA-aligned guidance states:

“Epinephrine is the primary treatment for anaphylaxis.”

“Administer immediately in patients with respiratory compromise from allergic reactions.”

Why the other options are incorrect:

A. Give a bronchodilatorMay help wheezing, but does not treat systemic anaphylaxis

B. Perform a primary surveyAlways important, but life-saving intervention (epinephrine) should not be delayed in obvious anaphylaxis

C. Immediately transportTransport is important, but treatment must begin immediately

Exact Extracts (NREMT-aligned EMT educational references):

“Administer epinephrine promptly in suspected anaphylaxis.”

“Respiratory distress after allergen exposure is an indication for epinephrine.”

“Delays in epinephrine administration increase mortality.”

Clinical Priority Summary:

In a patient with respiratory distress following a bee sting, the EMT must immediately administer epinephrine, making D the correct answer.

This is a high-risk cardiac event due to unstable angina or possible myocardial infarction. The EMT should:

Administer oxygen if SpOâ‚‚ is < 94%

Avoid nitroglycerin if systolic BP is < 90 mmHg

Obtain a 12-lead ECG to identify ST-elevation MI (STEMI) and transmit it if trained and authorized

CPAP is indicated for pulmonary edema, and albuterol is for bronchospasm, neither of which applies here.

The correct answer is D. 60 seconds.

This question is testing the special consideration of hypothermia in cardiac arrest assessment. In a patient found unresponsive in the snow, there is a high likelihood of severe hypothermia, which significantly slows metabolism and heart rate.

In hypothermic patients, pulses may be very slow and difficult to detect, so the EMT must take extra time to accurately determine whether a pulse is present before initiating CPR.

Standard pulse checks in normothermic patients are limited to no more than 10 seconds, but hypothermic patients are an exception.

Why 60 seconds is correct:

NREMT-aligned EMS guidelines emphasize that in severe hypothermia, the provider should assess the pulse for up to 60 seconds before concluding that the patient is pulseless. This is because hypothermia can produce extremely slow heart rates (bradycardia), and premature CPR could be inappropriate if a pulse is actually present.

Why the other options are incorrect:

A. 10 seconds: This is correct for standard cardiac arrest assessment in normothermic patients, but not for hypothermia.

B. 15 seconds and C. 30 seconds: These are not recommended durations in NREMT or AHA guidelines for pulse checks.

Exact Extracts:

“In a hypothermic patient, check the pulse for 30–60 seconds before determining pulselessness.”

“Severely hypothermic patients may have very slow heart rates that are difficult to detect.”

“Do not assume cardiac arrest until a careful and prolonged pulse assessment has been performed.”

The correct answer is D. applying direct pressure.

A perineal tear after childbirth is a form of external soft-tissue bleeding. The primary prehospital treatment for any external bleeding, including obstetric perineal tears, is direct pressure with sterile dressings.

According to NREMT EMT-level obstetrics care guidelines, bleeding control in the postpartum patient should follow standard hemorrhage control principles, with emphasis on direct pressure as the first-line intervention.

Why D is correct:

Direct pressure is the most effective and immediate method to control bleeding from a perineal tear.

It helps reduce blood loss and prevents further complications such as shock.

Why the other options are incorrect:

A. Packing her vagina with gauze → This is not appropriate in the prehospital setting and may cause further injury or infection.

B. Elevating her pelvis → Not a recognized or effective method for controlling perineal bleeding.

C. Having her keep her legs flexed → This does not control bleeding and has no role in treatment.

Exact Extracts:

“Control external bleeding with direct pressure using sterile dressings.”

“Postpartum bleeding should be managed with standard hemorrhage control techniques.”

“Direct pressure is the first step in controlling soft-tissue hemorrhage.”

The correct answer is B. The pulmonary artery, and would prevent blood from entering the lungs for gas exchange.

When a deep vein thrombosis (DVT) dislodges, it becomes an embolus and travels through the venous system to the right side of the heart and then into the pulmonary arteries. This results in a pulmonary embolism (PE).

The embolus will lodge in the pulmonary artery or its branches, not the pulmonary veins. The pulmonary veins carry oxygenated blood away from the lungs to the heart, so a clot from the venous system cannot reach them directly.

The primary problem caused by a pulmonary embolism is:

Obstruction of blood flow to portions of the lung

Impaired perfusion for gas exchange

This leads to a mismatch where air may still reach the alveoli, but blood cannot, preventing effective oxygenation.

According to NREMT-aligned EMT educational material:

“A pulmonary embolism blocks blood flow in the pulmonary circulation.”

“This prevents adequate gas exchange in the affected portions of the lung.”

Why the other options are incorrect:

A: While respiratory distress can occur, the key pathology is blocked perfusion, not simply a decrease in respirations.

C & D: Incorrect because emboli from DVT travel to the pulmonary arteries, not the pulmonary veins.

Exact Extracts:

“Pulmonary embolism occurs when a blood clot blocks a pulmonary artery.”

“This blockage prevents blood from reaching the alveoli for gas exchange.”

“Clots typically originate in the deep veins of the legs.”

Mechanism of Injury (MOI) assessment is a cornerstone of trauma care. It helps providers determine:

Extent of injury: High-speed collisions, falls from height, or penetrating trauma suggest internal injuries even if external signs are limited.

Need for additional resources: MOI may indicate the necessity of ALS backup, air transport, or technical rescue.

MOI cannot determine a patient’s medical history or guarantee survival predictions. The destination facility depends on multiple factors including triage protocols, vital signs, and local trauma system regulations.

The cerebrum is the largest and most developed part of the human brain and is responsible for higher cognitive functions. According to NREMT anatomy and physiology education, the cerebrum controls thinking, reasoning, memory, judgment, voluntary movement, and sensory interpretation.

Option B is correct because conscious thought, problem-solving, and decision-making all originate in the cerebrum.

Option A (Pons) helps regulate breathing and sleep cycles.

Option C (Brain stem) controls vital functions such as heart rate, breathing, and blood pressure.

Option D (Cerebellum) coordinates balance, posture, and fine motor movement.

Understanding brain function helps EMTs correlate neurological findings with possible injuries or medical conditions.

The correct answer is B. Abrasion.

An abrasion is a superficial injury caused by scraping or rubbing force that damages the epidermis (outer layer of skin). This type of injury is commonly referred to as a “scrape” or “road rash.”

Why B is correct:

Abrasions occur when the skin is rubbed or scraped against a rough surface.

They involve only the epidermis and are usually superficial.

Minimal bleeding may occur, but the main concern is pain and risk of infection.

Why the other options are incorrect:

A. Avulsion → Involves tearing away of skin or tissue, often deeper and more severe

C. Puncture → Caused by a sharp, pointed object penetrating the skin

D. Laceration → A cut or tear in the skin, typically deeper than an abrasion

Exact Extracts:

“An abrasion is a wound caused by scraping or rubbing of the skin.”

“It involves damage to the epidermis.”

“Abrasions are usually superficial but can be painful and prone to infection.”

Sickle cell crisis (vaso-occlusive crisis) occurs when abnormally shaped red blood cells obstruct blood flow, leading to:

Severe localized or generalized pain (most common symptom)

Often in the back, chest, abdomen, or long bones

Hypoxia may be a contributing factor, but pain is the most reported reason for EMS activation. Cardiac arrhythmias and hypertension are not primary symptoms of sickle cell crisis.
