NREMT EMT - Emergency Medical Technicians (EMT002) Exam

The correct answers are C. Bradycardia and D. Altered mental status.

This question focuses on distinguishing respiratory distress from respiratory failure in pediatric patients.

Respiratory distress = compensating (early signs)

Respiratory failure = decompensating (late, life-threatening signs)

Why C is correct (Bradycardia):

In children, bradycardia is a late and ominous sign of hypoxia.

It indicates the patient is decompensating and nearing respiratory arrest.

Why D is correct (Altered mental status):

Indicates inadequate oxygenation and/or ventilation to the brain.

A hallmark of respiratory failure, not just distress.

Why the other options are incorrect:

A. Coughing → Nonspecific, not indicative of failure

B. Tachypnea → Early compensatory sign of respiratory distress

E. Increased work of breathing → Also an early sign of distress, not failure

Exact Extracts:

“Respiratory failure is indicated by altered mental status and signs of poor oxygenation.”

“Bradycardia in pediatric patients is a late sign of hypoxia.”

“Increased work of breathing and tachypnea are signs of respiratory distress.”

The diaphragm is innervated by the phrenic nerve, which originates from spinal nerve roots C3–C5. NREMT teaching highlights the phrase: “C3, 4, and 5 keep the diaphragm alive.”

Option A (C4) is correct because an injury at or above this level can paralyze the diaphragm, resulting in apnea and immediate respiratory failure.

Option B (T1) and C (T3) affect intercostal muscles but not the diaphragm.

Option D (L4) affects lower extremity function only.

NREMT emphasizes that high cervical spine injuries are immediately life-threatening due to loss of ventilatory control.

The patient’s complaint of difficulty breathing is an airway/breathing issue and takes precedence over a controlled extremity bleed. The first action is to administer oxygen and evaluate respiratory effort.

Though reassessing the wound is important, oxygenation is the priority when airway compromise or respiratory distress is present. Tourniquets are for uncontrolled bleeding, which is not the case here.

The correct answer is B. Ventricular tachycardia only.

There are two primary shockable rhythms in cardiac arrest:

Ventricular fibrillation (VF)

Ventricular tachycardia (VT)

However, only one of these may still produce a pulse under certain conditions.

Why B is correct:

Ventricular tachycardia (VT) can occur with or without a pulse.

In some cases, VT allows the heart to generate enough cardiac output to produce a palpable pulse (this is called stable or unstable VT with a pulse).

Therefore, VT is the only shockable rhythm that may still have a pulse.

Why the other options are incorrect:

A. Ventricular fibrillation only → VF produces no organized cardiac activity, therefore no pulse

C. Both shockable rhythms → Incorrect because VF never produces a pulse

D. Neither a shockable rhythm → Incorrect because VT can produce a pulse

Exact Extracts:

“Ventricular fibrillation results in no effective cardiac output and no pulse.”

“Ventricular tachycardia may be present with or without a pulse.”

“Pulseless ventricular tachycardia and ventricular fibrillation are treated with defibrillation.”

The correct answer is A. Place a surgical mask on him.

This question focuses on infection control and standard precautions, which fall under EMS Operations in NREMT content.

The patient presents with:

Fever

Cough

Body aches

These are classic signs of a respiratory infectious illness, and EMS providers must immediately take steps to prevent transmission.

According to NREMT-aligned infection control principles, the first priority when dealing with a potentially infectious respiratory patient is source control, which means placing a surgical mask on the patient to limit the spread of droplets.

Why A is correct:

A surgical mask on the patient reduces transmission of respiratory droplets.

This is considered an immediate and appropriate standard precaution.

Why the other options are incorrect:

B. Administer oxygen: The patient’s SpO₂ is 99% on room air, indicating adequate oxygenation. NREMT guidelines emphasize that oxygen should be administered based on clinical need, not routinely.

C. Place an N95 mask on him: N95 respirators are intended for healthcare providers, not patients. The patient should receive a surgical mask, not an N95.

D. Transport him in the recovery position: This position is used for patients with decreased level of consciousness or risk of airway compromise, which is not indicated here.

Exact Extract (EMT-aligned educational content):

EMS providers must use standard precautions and take appropriate measures to prevent disease transmission.

For patients with suspected respiratory infections, placing a surgical mask on the patient helps prevent the spread of droplets.

Oxygen should be administered only when there are signs of hypoxia or respiratory distress, not when oxygen saturation is normal.

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.

The correct answer is C because in a third-trimester trauma patient with severe abdominal pain , vaginal bleeding , and clear signs of shock , the EMT should strongly suspect abruptio placentae . Official national EMS instructional guidance for pregnant trauma patients specifically lists separation of the placenta from the uterine wall as a key trauma concern, with abdominal pain and vaginal bleeding often present , and notes a high risk of fetal death . This matches the presentation in this question very closely. ( EMS.gov )

The correct answer is B. Diabetic ketoacidosis (DKA).

This question is testing recognition of classic signs of DKA, a life-threatening complication of diabetes characterized by hyperglycemia, ketosis, and metabolic acidosis.

The patient presents with hallmark findings:

Sweet/fruity odor on the breath → caused by ketones (acetone)

Nausea and vomiting → common in DKA

Warm, flushed, dry skin → due to dehydration

Rapid breathing (40/min) → Kussmaul respirations (deep, rapid breathing to compensate for acidosis)

According to NREMT-aligned EMT educational material:

“Patients with diabetic ketoacidosis often have a fruity odor on their breath.”

“Kussmaul respirations are deep and rapid breathing seen in metabolic acidosis.”

“DKA presents with dehydration, vomiting, and altered respiratory patterns.”

Why the other options are incorrect:

A. Hyperosmolar hyperglycemic syndrome (HHS):Typically occurs in older patients and does not produce ketones, so no fruity breath odor.

C. Toxic ingestion:Can cause vomiting, but does not classically produce fruity breath and Kussmaul respirations together.

D. Hypoglycemia:Usually presents with cool, clammy skin, altered mental status, and normal or shallow respirations—not fruity breath or deep rapid breathing.

Key NREMT Concept:

“Fruity breath odor + rapid deep respirations = Diabetic ketoacidosis.”

Exact Extracts:

“A fruity odor on the breath is a sign of ketoacidosis.”

“Kussmaul respirations are deep, rapid respirations associated with acidosis.”

“DKA patients are often dehydrated with warm, dry skin.”

The tripod position — sitting upright, leaning forward, supporting the upper body with arms on knees — is a classic sign of respiratory distress. This position:

Maximizes diaphragmatic movement

Engages accessory muscles of respiration

Improves air exchange in patients with obstructive airway diseases (e.g., COPD, asthma)

It is rarely used by patients with abdominal pain or seizures and is not associated with cardiac arrest (where unconsciousness is expected).
