Pass the NREMT Medical Technicians EMT Questions and answers with CertsForce

Comprehensive and Detailed Explanation (Based on NREMT standards):

NREMT trauma care guidelines clearly state that distal circulation, sensation, and motor function (CSM) must be assessed both before and after splinting any musculoskeletal injury.

Option C is correct because the pre-splint assessment establishes a baseline, while the post-splint assessment confirms that the splint has not compromised blood flow or nerve function.

Option A is incomplete and unsafe.

Option B misses baseline data.

Option D violates standard trauma care practices.

Proper documentation of distal neurological status is critical for patient safety and medico-legal protection.

The correct answer is C. Obstructive.

Why C is correct (Obstructive Shock):

Pericardial tamponade occurs when fluid accumulates in the pericardial sac, compressing the heart and preventing adequate filling of the ventricles. This leads to:

Decreased preload

Reduced cardiac output

Impaired circulation

This is classified as obstructive shock because there is a mechanical obstruction to blood flow, not a failure of the heart muscle itself.

NREMT-aligned cardiology guidelines state:

“Obstructive shock results from a physical obstruction to blood flow.”

“Examples include cardiac tamponade, tension pneumothorax, and pulmonary embolism.”

Why the other options are incorrect:

A. Cardiogenic: Caused by failure of the heart muscle (e.g., myocardial infarction), not external compression.

B. Distributive: Caused by widespread vasodilation (e.g., septic or anaphylactic shock).

D. Hypovolemic: Caused by loss of blood or fluids, not obstruction.

Exact Extracts:

“Cardiac tamponade is a cause of obstructive shock.”

“Obstructive shock impairs circulation due to mechanical obstruction.”

“Tamponade prevents normal cardiac filling and reduces output.”

The correct answers are D. Aspirin administration and E. Attaching AED pads.

This patient is presenting with classic signs of acute coronary syndrome (ACS):

Crushing, midsternal chest pain

Onset with exertion

Age and risk profile

D. Aspirin administration is a priority intervention. Aspirin helps by inhibiting platelet aggregation and limiting clot formation in coronary arteries.

NREMT-aligned guidance states:

“Administer aspirin to patients with suspected cardiac chest pain.”

E. Attaching AED pads is also correct because patients with suspected cardiac ischemia are at risk for sudden cardiac arrest. Continuous cardiac monitoring (via AED pads or monitor) allows for rapid defibrillation if needed.

NREMT material emphasizes early readiness for deterioration:

“Be prepared to manage sudden cardiac arrest in patients with chest pain.”

Why the other options are incorrect:

A. Sublingual nitroglycerin administration:EMTs may only assist with nitroglycerin if it is prescribed to the patient. This patient has no prescription medications, so nitroglycerin is contraindicated.

B. 12-lead acquisition and transmission:This is typically an ALS (paramedic-level) intervention, not standard EMT scope in NREMT context.

C. Applying supplemental oxygen:The patient’s SpO₂ is 95% on room air, which does not indicate hypoxia. NREMT guidelines recommend oxygen only if SpO₂ is low or patient is in respiratory distress.

NREMT guidance:

“Oxygen should be administered based on patient need, not routinely.”

Exact Extracts:

“Administer aspirin to patients with suspected cardiac chest pain.”

“Oxygen should be given only if the patient is hypoxic or shows signs of respiratory distress.”

“Be prepared for cardiac arrest in patients with suspected myocardial infarction.”

This is one of those EMS custody questions where the safest answer comes from remembering two transport rules at the same time: the patient needs medical transport , and the patient also needs safe restraint management .

Because the patient is being transported by EMS, the patient should be secured with appropriate medical restraints , not simply left in police handcuffs alone. That makes removing the handcuffs and applying soft restraints the proper EMS approach, provided law enforcement is involved in that process. Just as important, the officer with the key should ride along so the restraint situation remains safe and legally controlled during transport.

The rest of the scenario also hints that this patient may be medically unstable, not just angry. The hot, diaphoretic skin , marked tachycardia , and severe agitation raise concern for a serious behavioral or medical emergency, so EMS transport is appropriate. Also, NREMT-style operations questions consistently reject prone restraint because face-down positioning increases the risk of respiratory compromise during transport.

The correct answer is B. Hypovolemic shock.

Key findings in this scenario:

Sudden “tearing” chest pain → classic sign of aortic dissection or rupture

Hypotension (BP 88/52)

Tachycardia (P 128)

Pale, cool, clammy skin

Clear lung sounds

Why this indicates hypovolemic shock:

A tearing chest pain strongly suggests a vascular catastrophe (e.g., aortic dissection/rupture), which can lead to internal bleeding. This results in:

Loss of circulating blood volume

Decreased perfusion

Signs of hypovolemic shock

NREMT-aligned guidance states:

“Hypovolemic shock results from significant fluid or blood loss.”

“Patients present with hypotension, tachycardia, and cool, pale skin.”

Why NOT cardiogenic shock (C):

Although the patient has a cardiac history:

Cardiogenic shock typically presents with:

Pulmonary edema (crackles)

Signs of heart pump failure

This patient has clear lung sounds, which argues against cardiogenic shock

Why the other options are incorrect:

A. PsychogenicCauses temporary fainting, not sustained hypotension with shock signs

D. SepticUsually presents with warm skin (early) and signs of infection, not tearing chest pain

Exact Extracts (NREMT-aligned EMT educational references):

“Hypovolemic shock is caused by blood or fluid loss.”

“Signs include hypotension, tachycardia, and cool, pale skin.”

“Internal bleeding can result in hypovolemic shock.”

Clinical Priority Summary:

The tearing chest pain with hypotension and signs of poor perfusion strongly suggests internal hemorrhage, leading to hypovolemic shock, making B the correct answer.

The correct answers are A and B because standard EMT care for epistaxis (nosebleed) includes having the patient lean forward and applying direct pressure by pinching the nostrils .

Leaning forward prevents blood from draining into the airway or stomach, reducing the risk of aspiration or vomiting. Pinching the nostrils provides direct pressure to control bleeding , which is the primary intervention emphasized in NREMT-aligned bleeding control guidelines.

Send the next question.

The correct answer is A because standard precautions require hand hygiene after contact with body fluids or contaminated items and immediately after glove removal . CDC guidance states to clean hands after contact with blood, body fluids, or contaminated surfaces and immediately after glove removal , and OSHA likewise requires handwashing immediately or as soon as feasible after removal of gloves . This is the EMT priority after handling a body-fluid-contaminated dressing.

The correct answer is C. false imprisonment.

In EMS legal concepts, false imprisonment is defined as the unauthorized confinement or restraint of a person without legal justification or consent. This can occur if an EMT prevents a patient from leaving when the patient has the right to refuse care.

Why C is correct:

False imprisonment involves restricting a person’s freedom of movement without proper authority.

In EMS, this includes situations where a competent patient is held against their will.

Why the other options are incorrect:

A. Battery → Involves unlawful physical contact or touching without consent

B. Kidnapping → Involves unlawful transport or movement of a person, typically with criminal intent

D. Assault → Involves threatening harm or creating fear of harm, not confinement

Exact Extracts:

“False imprisonment is the unauthorized confinement of a person.”

“A patient who is competent has the right to refuse care and transport.”

“Restraining a patient without legal authority may constitute false imprisonment.”

The correct answer is A because these described qualities— rapid situation assessment, taking control, prioritizing actions, and giving clear direction —are core elements of leadership in EMS .

NREMT-aligned EMS education identifies leadership as the ability to direct others effectively, make decisions under pressure, and coordinate patient care activities , especially during emergency scenes. Strong leadership ensures efficient scene management, clear communication, and optimal patient outcomes.

The symptoms described are classic for a stroke (CVA). Additional hallmark findings include:

Arm drift (motor weakness or hemiparesis)

Facial droop (Cranial nerve VII involvement)

Slurred speech (dysarthria or aphasia)

These form the basis of prehospital stroke assessment tools like FAST:

Face drooping

Arm weakness

Speech difficulty

Time to call 911

Miosis (pupil constriction) and tremors are not associated with stroke in EMS context. Syncope is an isolated event and not a reliable CVA symptom.
