Free NREMT EMT Practice Exam with Questions & Answers | Set: 2

The correct answer is B. Fowler.

This patient is presenting with signs of acute pulmonary edema or congestive heart failure, including:

Shortness of breath

Crackles (fluid in the lungs)

Hypertension

Anxiety and pale, clammy skin

In such cases, the best position is upright (Fowler’s position) to improve breathing.

Why B is correct:

Fowler’s position (sitting upright) helps maximize lung expansion.

It reduces venous return to the heart, decreasing pulmonary congestion.

It improves oxygenation and patient comfort in respiratory distress.

Why the other options are incorrect:

A. Supine → Worsens breathing by increasing pressure on the lungs and fluid accumulation

C. Semi-Fowler → Helpful, but not as effective as full Fowler’s for severe respiratory distress

D. Lateral recumbent → Used for unconscious patients or airway protection, not respiratory distress

Exact Extracts:

“Patients with respiratory distress should be placed in a sitting or Fowler’s position if tolerated.”

“An upright position facilitates breathing and improves lung expansion.”

“Pulmonary edema patients benefit from being positioned upright to reduce fluid in the lungs.”

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.

Using the START triage system, patients are categorized based on Respirations, Perfusion, and Mental Status (RPM).

A respiratory rate greater than 30 breaths per minute immediately qualifies the patient as RED (Immediate). Additionally, delayed capillary refill ( > 2 seconds) further supports this classification.

Option A is correct.

Option B applies to stable patients who can wait.

Option C is for deceased or nonsalvageable patients.

Option D is for minor injuries.

NREMT teaches that patients with compromised airway or perfusion are the highest priority.

This patient’s presentation—older age, severe back pain radiating to the chest, hypotension, and a pulsating abdominal mass—is highly suggestive of an abdominal aortic aneurysm (AAA). NREMT teaching stresses early recognition of life-threatening medical conditions and avoiding interventions that could worsen the patient’s condition.

Option A (Position of comfort) is correct because patients with suspected AAA should be kept calm and positioned in a way that minimizes pain and stress, which can reduce sympathetic stimulation and the risk of aneurysm rupture.

Option D (Supplemental oxygen) is correct because the patient’s SpO₂ is 89%, indicating hypoxia. NREMT guidelines recommend administering oxygen to maintain adequate oxygenation in critically ill or potentially unstable patients.

Option B is incorrect because AED pads are not indicated unless the patient is in cardiac arrest or has a high risk of imminent arrest. There is no evidence of dysrhythmia or arrest at this time.

Option C is incorrect because aspirin is indicated for suspected acute coronary syndromes, not AAA. Aspirin could worsen internal bleeding if the aneurysm ruptures.

Option E is incorrect because nitroglycerin can cause vasodilation and hypotension, potentially precipitating aneurysm rupture.

In summary, NREMT emphasizes supportive care, oxygenation, and rapid transport for suspected AAA while avoiding medications that increase bleeding risk or lower blood pressure.

The correct answers are D. Place the device in the larger nostril and E. Lubricate the distal tip.

Proper insertion of a nasopharyngeal airway (NPA) follows specific steps outlined in NREMT-aligned airway management guidelines.

Correct Steps:

1. Choose the larger nostril (D):

The NPA should be inserted into the nostril with better airflow (larger nostril) to reduce resistance and trauma.

This improves ease of insertion and patient comfort.

2. Lubricate the distal tip (E):

The airway must be lubricated with a water-soluble lubricant before insertion.

This minimizes friction and reduces the risk of nasal mucosal injury or bleeding.

NREMT-aligned references state:

“Insert the NPA into the larger nostril when possible.”

“Lubricate the airway prior to insertion.”

Why the other options are incorrect:

A. Measure from the corner of the mouth to the tip of the ear → Incorrect

This measurement is used for an oropharyngeal airway (OPA), not an NPA.

NPA is measured from nose to earlobe.

B. Follow the base of the tongue during insertion → Incorrect

This applies to OPA insertion, not NPA.

NPA is inserted along the floor of the nasal passage.

C. Insert the bevel away from the septum → Incorrect

The bevel should face toward the septum (medially), not away.

Exact Extracts (NREMT-aligned EMT educational references):

“Measure NPA from the nostril to the earlobe.”

“Lubricate the airway before insertion.”

“Insert into the larger nostril if possible.”

“Advance gently along the nasal floor.”

Clinical Priority Summary:

Correct NPA insertion requires proper nostril selection and lubrication, making D and E the correct answers.

The correct answers are A. Prevent hypoxemia and C. Maintain airway patency.

This patient is showing signs of airway compromise:

Swelling around the mouth

Stridor → indicates upper airway obstruction

These findings strongly suggest a caustic ingestion with airway edema, which can rapidly progress to complete airway obstruction.

Priority: Airway and Breathing (ABCs)

According to NREMT principles, the highest priority is airway management and oxygenation.

1. Maintain airway patency (C):

Swelling and stridor indicate a narrowing airway

Immediate action is required to keep the airway open

Prepare for suctioning, positioning, and possible advanced airway support

2. Prevent hypoxemia (A):

Due to airway compromise, the patient is at high risk for inadequate oxygenation

Administer high-flow oxygen and monitor closely

NREMT-aligned guidance states:

“Airway compromise takes priority in caustic ingestions.”

“Stridor indicates impending airway obstruction.”

“Ensure airway patency and adequate oxygenation first.”

Why the other options are incorrect:

B. Identify the chemicalImportant, but not the immediate priority over airway management

D. Irrigate the affected areaMay be appropriate for external exposures, but airway takes priority here

E. Administer activated charcoalContraindicated in caustic ingestions and in patients with airway compromise or vomiting risk

Exact Extracts (NREMT-aligned EMT educational references):

“Airway management is the priority in patients with signs of airway compromise.”

“Stridor is a sign of upper airway obstruction.”

“Do not administer activated charcoal in caustic ingestions.”

Clinical Priority Summary:

Because this patient shows airway swelling and stridor, the EMT must immediately focus on airway patency and oxygenation, making A and C the correct answers.

The correct answer is A. Epidural hematoma.

This question describes a classic “lucid interval”, which is strongly associated with an epidural hematoma.

Key features in the scenario:

Initial loss of consciousness

Followed by a period of temporary recovery (lucid interval)

Then rapid deterioration back to unresponsiveness

Why A is correct:

Epidural hematomas typically result from arterial bleeding (often the middle meningeal artery).

Patients often present with:

Brief loss of consciousness

Lucid interval (temporary improvement)

Rapid decline as pressure increases in the skull

This pattern is a hallmark finding emphasized in EMT training.

Why the other options are incorrect:

B. Subdural hemorrhage → Usually has a slow, gradual onset, especially in older adults, without a classic lucid interval

C. Intracerebral hematoma → Causes progressive neurological deficits, not a lucid interval pattern

D. Subarachnoid hemorrhage → Typically presents with sudden severe headache (“worst headache of life”), not trauma-related lucid intervals

Exact Extracts:

“Epidural hematomas are often associated with a lucid interval followed by rapid deterioration.”

“Patients may lose consciousness, regain it briefly, and then deteriorate rapidly.”

“Subdural hematomas typically present more gradually, especially in older patients.”

This patient is experiencing anaphylactic shock, evidenced by hypotension, respiratory distress, hypoxia, and altered mental status. After epinephrine administration, NREMT priorities focus on aggressive oxygenation and airway support.

Option D is correct because a non-rebreather mask at high flow delivers the highest concentration of oxygen to a spontaneously breathing patient and is indicated with SpO₂ of 86%.

Option C would be indicated only if respirations were inadequate or absent.

Option B is insufficient for severe hypoxia.

Option A delays definitive supportive care.

NREMT emphasizes epinephrine first, followed immediately by high-flow oxygen and rapid transport.

The correct answer is C. False imprisonment.

In EMS legal concepts, false imprisonment is defined as:

Unlawfully restraining or confining a person without legal authority or the person’s consent

This can occur if an EMT prevents a competent patient from leaving or restrains them without proper justification.

NREMT-aligned legal guidance states:

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

“It occurs when a patient is restrained or not allowed to leave without consent or legal authority.”

Why the other options are incorrect:

A. BatteryRefers to unlawful physical touching without consent

B. KidnappingInvolves forcible abduction and movement, not just confinement

D. AssaultRefers to threatening harm, not actual confinement

Exact Extracts (NREMT-aligned EMT educational references):

“False imprisonment involves holding a patient against their will.”

“Patients have the right to refuse care if competent.”

“Unlawful restraint may result in legal liability.”

Clinical Priority Summary:

Unauthorized confinement of a patient is legally defined as false imprisonment, making C the correct answer.

Perfusion refers to delivery of oxygen and nutrients to tissues. It depends on three essential components:

Patent airway: Ensures oxygen reaches lungs

Intact microcirculation: Capillary-level exchange must function

Sufficient blood volume: Maintains blood pressure and oxygen transport

Hypoxic drive relates to COPD physiology, not perfusion. High alveolar pressure (like from CPAP) may impede venous return, and a low ventilation-perfusion ratio means poor oxygenation efficiency, which negatively affects perfusion.
