Free NREMT EMT Practice Exam with Questions & Answers | Set: 4

The correct answers are C. Crackles and E. Dependent edema.

This patient has a history of chronic obstructive pulmonary disease (COPD) with signs suggesting a respiratory infection or exacerbation (productive cough with green sputum).

C. Crackles — Correct

Crackles (rales) are commonly heard in COPD patients, especially during exacerbations or when infection (such as bronchitis or pneumonia) is present.

NREMT-aligned material states:

“Abnormal breath sounds such as wheezes and crackles may be present in patients with lower airway disease.”

Crackles indicate:

Fluid or mucus in the airways

Impaired gas exchange

E. Dependent edema — Correct

Patients with long-standing COPD may develop cor pulmonale (right-sided heart failure) due to chronic hypoxia.

This leads to:

Fluid retention

Swelling in the lower extremities (dependent edema)

NREMT-aligned guidance:

“Chronic lung disease can lead to right-sided heart failure, resulting in peripheral edema.”

Why the other options are incorrect:

A. A rash:Not associated with COPD.

B. Stridor:Indicates upper airway obstruction, not lower airway disease like COPD.

D. Hot, moist skin:More consistent with fever or heat illness, not a typical COPD finding.

Key NREMT Concepts:

COPD = lower airway disease → wheezes, crackles

Chronic COPD → cor pulmonale → dependent edema

Exact Extracts:

“COPD is characterized by lower airway obstruction and abnormal breath sounds.”

“Crackles may be present due to fluid or mucus in the lungs.”

“Chronic hypoxia can lead to right-sided heart failure and peripheral edema.”

The correct answer is D. utilize the incident command structure.

Key Concept: Incident Command System (ICS)

The most important principle in managing a multiple casualty incident (MCI) is the use of a structured command system. The Incident Command System (ICS) provides:

Organization

Clear leadership

Efficient communication

Resource management

Why D is correct:

ICS ensures that:

Roles are clearly defined (triage, treatment, transport, staging, etc.)

Resources are used efficiently

Scene operations are coordinated and controlled

NREMT-aligned guidance states:

“The Incident Command System is essential for managing mass casualty incidents.”

“ICS provides organization and structure to chaotic scenes.”

Why the other options are incorrect:

A. Defer decisions to chief officer❌ ICS begins with first arriving unit, not delayed leadership

B. Request additional resources early✔ Important, but not the key foundational principle

C. Initiate START triage immediately✔ Important step, but only one component of overall management

Exact Extracts (NREMT-aligned EMT educational references):

“Use of the Incident Command System is critical in MCI management.”

“ICS ensures coordinated response and resource allocation.”

“All operations should function within the ICS framework.”

Clinical Priority Summary:

The foundation of effective MCI management is organization through ICS, making D the correct answer.

This scenario suggests a potential multiple-casualty incident with a possible environmental hazard, such as carbon monoxide or another toxic gas. NREMT places strong emphasis on scene size-up as the first and most critical step in EMS operations.

Option B is correct because determining the size and scope of the incident allows the EMT to assess scene safety, identify hazards, estimate the number of patients, and determine the need for additional resources. Entering the scene without this assessment could result in responder injury or death.

Option A is incorrect because establishing command typically follows an initial size-up. Command cannot be effectively established without understanding the nature of the incident.

Option C is incorrect because announcing the presence of poisonous gas without confirmation may cause panic and is not an appropriate first action.

Option D is incorrect because attempting rescue before confirming scene safety violates NREMT’s core principle that rescuer safety comes first.

NREMT standards clearly state that EMTs must never enter a potentially hazardous scene until it has been properly assessed and deemed safe or appropriate resources are requested.

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 correct answers are B. Bradycardia, C. Hypertension, and F. Cheyne-Stokes respirations.

This question is testing recognition of increased intracranial pressure (ICP), specifically the classic findings known as Cushing’s triad and abnormal breathing patterns.

Why B and C are correct (Cushing’s Triad):

Cushing’s triad is a hallmark of increased ICP and includes:

Hypertension (widening pulse pressure)

Bradycardia

Irregular respirations

NREMT-aligned trauma guidelines state:

“Increasing intracranial pressure may present with hypertension and bradycardia.”

These are late and critical signs of brain herniation risk.

Why F is correct (Cheyne-Stokes respirations):

Cheyne-Stokes respirations are:

An abnormal breathing pattern (alternating periods of apnea and rapid breathing)

Associated with brain injury and increased ICP

Guidelines emphasize:

“Irregular breathing patterns such as Cheyne-Stokes may indicate brain injury.”

Why the other options are incorrect:

A. Tachycardia: Typically seen in shock, not increased ICP.

D. Hypotension: Suggests shock; ICP usually causes hypertension.

E. Kussmaul respirations: Associated with metabolic acidosis (e.g., diabetic ketoacidosis), not ICP.

Exact Extracts:

“Cushing’s triad includes hypertension, bradycardia, and irregular respirations.”

“Irregular respirations such as Cheyne-Stokes are associated with brain injury.”

“These findings indicate increasing intracranial pressure and possible herniation.”

The correct answers are B. Apply continuous positive airway pressure (CPAP) and D. Administer a beta-2 agonist.

This patient is in moderate to severe respiratory distress with:

Tachypnea (R 30)

Hypoxia (SpO₂ 89%)

Wheezing → indicates bronchoconstriction (asthma/COPD exacerbation)

Why B is correct (CPAP):

CPAP helps keep alveoli open, improves oxygenation, and reduces work of breathing.

It is indicated in patients who are awake, breathing, and in respiratory distress with hypoxia.

Especially beneficial in COPD exacerbations.

Why D is correct (Beta-2 agonist):

Beta-2 agonists (e.g., albuterol) relax bronchial smooth muscle, relieving wheezing and bronchospasm.

This directly treats the underlying problem in asthma/COPD exacerbation.

Why the other options are incorrect:

A. 3 LPM nasal cannula → Too low for significant hypoxia (SpO₂ 89%); patient needs more aggressive support

C. Recovery position → Used for unconscious patients, not alert patients in respiratory distress

E. Rescue breathing → Indicated for inadequate respirations, but this patient is breathing (though rapid)

Exact Extracts:

“CPAP is indicated for patients with respiratory distress who are breathing spontaneously.”

“Beta-agonists are used to relieve bronchospasm in asthma and COPD.”

“Patients with wheezing benefit from bronchodilator therapy.”

A good way to separate AMI from more typical angina is to look for signs that the pain is more severe, more persistent, and less responsive to the usual triggers and relief measures .

That is why A, D, and F are the best answers here. A patient having an acute myocardial infarction may look pale or gray , which reflects poor perfusion and sympathetic stress during a cardiac event. Chest pain that lasts longer than 10 minutes points away from classic stable angina, which is often brief and improves with rest. And when nitroglycerin gives little or no relief , that raises concern that the problem is more serious than routine angina. The American Heart Association notes that stable angina usually happens with activity or strong emotions and is often treated with rest, medication, or both , while worsening or persistent chest discomfort is more concerning for a heart attack or other serious heart problem. ( www.heart.org )

From an EMT test-taking perspective, B and C sound more like classic stable angina patterns: pain brought on by exertion or stress and pain that improves with rest. Also, while nitroglycerin response by itself is not a perfect diagnostic tool in real-world medicine, NREMT-style questions commonly use poor relief with nitro plus prolonged pain as clues that the patient may be having an AMI rather than angina . Merck also notes that nitroglycerin response alone should not be used to diagnose chest pain, which is why the whole pattern matters. ( Merck Manuals )

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.”

Comprehensive and Detailed Explanation (Based on NREMT standards):

Continuous Positive Airway Pressure (CPAP) is used in patients with moderate to severe respiratory distress who are conscious and able to maintain their airway. NREMT guidelines identify specific respiratory conditions where CPAP improves oxygenation and ventilation.

Option A (Chronic bronchitis) is correct because CPAP helps overcome airway collapse and improves gas exchange in COPD patients.

Option B (Pulmonary edema) is correct because CPAP reduces preload and afterload while forcing fluid out of alveoli, improving oxygenation.

Option C (Acute bronchospasms) is correct because CPAP helps splint open airways and reduce work of breathing.

Option D is incorrect because CPAP is not used for isolated myocardial infarction without respiratory failure.

Option E is contraindicated because positive pressure can worsen a pneumothorax.

Option F is contraindicated due to airway burns and potential inhalation injury.

NREMT stresses proper patient selection to prevent CPAP-related complications.

This pattern is the classic opioid toxidrome . The two clues that matter most are pinpoint pupils and severely depressed breathing . Hydrocodone is an opioid , and opioids commonly cause respiratory depression , decreased responsiveness, and miosis . WHO and other medical references describe opioid overdose with slowed or stopped breathing and constricted pupils, which matches this patient closely. ( World Health Organization )

So in EMT-style reasoning, when you see unresponsive + agonal respirations + pinpoint pupils , think opioid ingestion first . Among the choices given, hydrocodone is the best match. ( MedlinePlus )
