NREMT EMT - Emergency Medical Technicians (EMT002) Exam

Cold-water submersion changes the usual cardiac arrest approach because hypothermia can slow metabolism and sometimes preserve viability longer than expected . That is why EMS and resuscitation teaching emphasizes the principle often summarized as “not dead until warm and dead.” In other words, before stopping resuscitation in a hypothermic drowning patient, the patient should be adequately rewarmed first. Resuscitation guidance for hypothermic cardiac arrest states that termination decisions should generally wait until rewarming has occurred, commonly to at least about 32°C (90°F) if there is still no return of circulation. ( wms.org )

So the correct choice is A because rewarming is the key condition that must happen before considering termination in this kind of case. ( RCEM Learning )

The correct answer is C because this patient is showing signs of respiratory failure , including a respiratory rate of 8 (too slow) , shallow breathing , cyanosis , and altered mental status .

NREMT-aligned airway and breathing guidelines state that patients with inadequate respirations require positive pressure ventilation with a bag-valve mask (BVM) . Simply increasing oxygen or switching masks is not sufficient when the patient is not ventilating effectively.

Therefore, immediate BVM ventilation with high-flow oxygen is the appropriate first intervention to support oxygenation and ventilation.

The correct answer is B. Breach of ethics.

This scenario describes inappropriate attitude and professional behavior by the EMT, not a failure that caused patient harm.

The EMT:

Provided appropriate medical care (oral glucose and transport)

The patient recovered

No harm resulted from not providing a blanket

However, the EMT’s statement reflects:

Disrespect toward the patient

Lack of compassion

Unprofessional conduct

Why B is correct (Breach of ethics):

NREMT standards emphasize professionalism and patient respect:

EMTs are expected to treat all patients with dignity, empathy, and respect

Ethical violations occur when providers demonstrate unprofessional attitudes or disregard for patient well-being

This situation reflects a violation of ethical standards, not legal negligence.

Why the other options are incorrect:

A. Breach of duty: Requires failure to provide care that leads to harm; care was appropriately provided.

C. Negligence: Requires duty, breach, causation, and damages; no patient harm occurred.

D. Battery: Involves unauthorized physical contact; not applicable here.

Exact Extracts:

“EMS providers must demonstrate professionalism and respect toward all patients.”

“Ethical conduct includes compassion and appropriate attitude.”

“Negligence requires proof of harm resulting from a breach of duty.”

The correct answer is D. Apply humidified oxygen.

This patient presentation is highly suggestive of epiglottitis, a life-threatening upper airway infection commonly seen in pediatric patients.

Key findings:

Drooling → inability to swallow secretions

Stridor → upper airway obstruction

Fever (102.4°F) → infection

Anxiety and tachycardia → respiratory distress

Why D is correct:

The priority is to maintain airway patency without agitating the child.

Humidified oxygen helps improve oxygenation while minimizing airway irritation.

It is the safest initial intervention in suspected epiglottitis.

Why the other options are incorrect:

A. Visualize the airway → Can trigger complete airway obstruction due to swelling

B. Suction posterior pharynx → May stimulate gag reflex and worsen obstruction

C. Insert oropharyngeal airway → Contraindicated in conscious or semi-conscious patients and may cause airway collapse

Exact Extracts:

“Do not attempt to visualize the airway in suspected epiglottitis.”

“Avoid any procedure that may agitate the child and cause airway obstruction.”

“Provide humidified oxygen and transport promptly.”

The correct answer is A. Atherosclerosis.

This patient is experiencing positional (orthostatic) symptoms, including:

Dizziness / feeling faint

Blurred vision

Symptoms that occur when standing and resolve at rest

In elderly patients, this pattern strongly suggests reduced cerebral perfusion upon standing, often due to vascular insufficiency from atherosclerosis.

Key reasoning:

Atherosclerosis causes narrowing and stiffening of arteries.

This limits the body’s ability to quickly adjust blood flow during position changes.

As a result, transient cerebral hypoperfusion occurs when standing, causing the described symptoms.

Why A is correct:

It best explains age-related vascular insufficiency and positional symptoms.

The patient’s elevated blood pressure also supports chronic vascular disease.

Why the other options are incorrect:

B. Cardiac arrhythmia: Typically causes sudden, unpredictable symptoms, not consistently position-related.

C. Transient ischemic attack (TIA): Causes focal neurological deficits, not just positional dizziness that resolves with rest.

D. Dissecting aortic aneurysm: Presents with severe, tearing chest or back pain, not positional lightheadedness.

Exact Extract (EMT-aligned educational content):

Elderly patients commonly experience dizziness or syncope due to decreased cerebral perfusion.

Atherosclerosis reduces vascular elasticity and blood flow, impairing the body’s ability to compensate for position changes.

Symptoms such as lightheadedness and blurred vision upon standing indicate transient cerebral hypoperfusion.

The correct answer is C because after inhaling medication from a metered-dose inhaler (MDI) , the patient should hold their breath for about 5–10 seconds .

NREMT-aligned EMT medication administration guidelines emphasize this step because it allows the medication to deposit deeply into the lungs , improving its effectiveness in treating bronchoconstriction. Immediately exhaling would reduce the amount of medication that reaches the lower airways.

The correct answer is A. Fluid overload.

Missed dialysis → inability to remove excess fluid

Shortness of breath + crackles → fluid in the lungs (pulmonary edema)

Hypertension (188/90)

Tachycardia (120)

Low-normal SpOâ‚‚ (92%)

These findings strongly indicate fluid overload leading to pulmonary edema.

Patients who miss dialysis retain excess fluid

Fluid accumulates in the lungs → crackles and respiratory distress

Hypertension is common due to increased circulating volume

B. Bronchiolitis → Typically seen in infants/children, not adults

C. Pneumonia → May cause crackles, but does not explain missed dialysis + fluid retention + hypertension pattern

D. Ascites → Fluid in the abdomen, not primarily causing lung crackles or acute respiratory distress

“Patients with renal failure who miss dialysis may develop fluid overload.”

“Pulmonary edema presents with crackles and respiratory distress.”

“Hypertension is commonly associated with fluid overload states.”

Comprehensive and Detailed Explanation:

The correct answer is A. secondary prevention.

Key Concept: Levels of Prevention

EMS and public health recognize three levels of prevention:

Primary prevention

Prevents the injury or illness before it occurs

Example: seat belts, vaccinations

Secondary prevention ✅

Reduces the effects of an illness or injury that has already occurred or cannot be fully prevented

Focuses on early detection and limiting severity

Tertiary prevention

Reduces long-term complications and disability

Example: rehabilitation

Why A is correct (Secondary Prevention):

The question states:“limit the effects of an injury or illness that you cannot completely prevent”

This directly matches the definition of secondary prevention, which aims to:

Minimize severity

Detect problems early

Prevent worsening

Why the other options are incorrect:

B. Primary prevention❌ Focuses on stopping the problem before it starts, not limiting effects

C. Reactive prevention❌ Not a recognized EMS/public health category

D. Proactive prevention❌ Also not a formal classification in EMS prevention models

Key Takeaway:

Primary = prevent occurrence

Secondary = limit effects (correct answer)

Tertiary = reduce long-term impact

The position of the patient’s head within the aircraft affects access to airway management and crew maneuverability. If the head is oriented away from providers or toward a non-accessible bulkhead, this can delay critical interventions (airway suctioning, ventilations).

Use of air splints, maintaining oxygen saturation, or environmental humidity are not major complications relative to physical positioning and in-cabin access limitations.

The correct answers are A. Bradycardia and C. Unequal pupils.

Why A and C are correct:

These findings are classic indicators of increased intracranial pressure (ICP) and significant brain injury.

Part of Cushing’s Triad (late sign of increased ICP)

Indicates brainstem involvement and impending herniation

Suggests brain compression or herniation

Indicates pressure on cranial nerves (especially CN III)

NREMT-aligned guidance states:

“Signs of increased intracranial pressure include bradycardia and unequal pupils.”

“Changes in pupillary size and reactivity indicate neurologic deterioration.”

Why the other options are incorrect:

B. Hypotension: More indicative of shock, not isolated brain injury (brain injury often presents with hypertension, not hypotension).

D. Cold, clammy skin: Suggests hypovolemic shock, not brain injury.

E. Delayed capillary refill: Also indicates poor perfusion/shock, not specific to brain injury.

Exact Extracts:

“Increased intracranial pressure may present with bradycardia.”

“Unequal pupils are a sign of brain injury and possible herniation.”

“Cushing’s response includes bradycardia and hypertension.”
