Free Practice Questions for NREMT EMT Exam

Crowing, also known as stridor, is a high-pitched sound heard during inspiration and indicates upper airway obstruction, often caused by swelling, foreign body, or infection such as croup or epiglottitis.

Option D is correct.

Option A (Rhonchi) and B (Wheezing) are lower airway sounds.

Option C (Bubbling) suggests fluid in the airway, not obstruction.

NREMT emphasizes rapid recognition of stridor because upper airway obstruction can quickly become fatal.

A deposition is a formal legal proceeding in which sworn testimony is taken prior to trial. NREMT education on EMS operations, documentation, and legal responsibilities emphasizes that EMTs may be required to participate in depositions as part of civil or criminal cases involving patient care.

Option C is correct because attorneys for all involved parties are typically present during a deposition. These may include attorneys representing the plaintiff, defendant, EMS agency, or insurance providers. The EMT provides sworn testimony under oath, and the deposition may later be used in court.

Option A is incorrect because deposition testimony is admissible in court under many circumstances.

Option B is incorrect because depositions are not presided over by a judge; they are conducted by attorneys.

Option D is incorrect because exhibits such as patient care reports, protocols, or photographs may be introduced during a deposition.

NREMT stresses the importance of accurate documentation, professionalism, and honesty, as EMTs are legally accountable for their actions and statements.

The correct answers are A, C, and E because this patient is experiencing suspected acute coronary syndrome (ACS) with hypoxia (SpO₂ 88%) and borderline hypotension .

Aspirin is indicated in suspected cardiac chest pain to reduce platelet aggregation and improve outcomes.

Oxygen is appropriate because the SpO₂ is below 94% , indicating hypoxemia.

Position of comfort (usually sitting upright) helps reduce cardiac workload and improves breathing.

NREMT guidelines emphasize treating hypoxia, reducing cardiac workload, and administering aspirin early in suspected ACS.

CPAP is not indicated due to low blood pressure (92 systolic) , and AED use is not appropriate because the patient is not in cardiac arrest.

The correct answer is B. Administer epinephrine.

This patient is experiencing anaphylactic shock, a life-threatening allergic reaction.

Key findings indicating anaphylaxis:

Sudden onset respiratory distress (wheezing)

Urticaria (hives) → hallmark allergic reaction

Hypotension (BP 82/48) → indicates shock

Hypoxia (SpO₂ 91%)

Why B is correct:

Epinephrine is the first-line, life-saving treatment for anaphylaxis.

It works by:

Bronchodilation (improves wheezing)

Vasoconstriction (raises blood pressure)

Reduces airway swelling

It must be given immediately when anaphylaxis is suspected.

Why the other options are incorrect:

A. Nebulized albuterol → Helps wheezing but does not treat shock or airway swelling

C. High-flow oxygen → Important, but not definitive treatment; epinephrine takes priority

D. Immediate transport → Necessary, but life-saving intervention must occur first

Exact Extracts:

“Epinephrine is the first-line treatment for anaphylaxis.”

“Anaphylaxis presents with respiratory distress, hypotension, and hives.”

“Immediate administration of epinephrine is critical.”

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.”

Comprehensive and Detailed Explanation (Based on NREMT standards):

Electrical injuries commonly disrupt the heart’s electrical conduction system. NREMT teaching emphasizes that cardiac dysrhythmias are the leading cause of unresponsiveness following electrical exposure, even when external burns appear minor.

Option A is correct because electrical current can induce lethal dysrhythmias such as ventricular fibrillation or asystole, resulting in sudden loss of consciousness.

Option B is incorrect because internal bleeding is not a primary consequence of electrical injury.

Option C may occur but does not typically cause immediate unresponsiveness.

Option D is less likely than cardiac involvement and is not the most common cause.

NREMT stresses continuous cardiac monitoring and rapid transport for all electrical injury patients due to the high risk of sudden cardiac arrest.

This situation describes contacting the medical director directly for patient-specific instructions , which is the definition of on-line medical direction . In national EMS education guidance used by NREMT-aligned programs, EMTs must be able to consult on-line medical direction when needed.

Why B is correct:

When an EMT calls for permission or orders to give an additional dose of nitroglycerin , that is real-time communication with physician oversight. This is on-line medical direction rather than a standing order. The EMS curriculum also explains that medication administration such as nitroglycerin may occur with medical direction approval .

Why the other options are wrong:

A. standard operating protocols — these are standing rules or preapproved procedures followed without calling for a new patient-specific order.

C. evidence-based medicine — this means care guided by research and best evidence, not a phone/radio order from medical control.

D. continuous quality improvement — this refers to reviewing and improving system performance, not obtaining treatment orders during active patient care.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Sudden respiratory symptoms following prolonged cleaning strongly suggest chemical inhalation, particularly from cleaning agents such as ammonia or bleach. Mixing chemicals or using them in poorly ventilated areas can release toxic gases that cause coughing, nausea, and dyspnea.

Option D is correct because inhaled chemical irritants commonly cause acute respiratory distress that improves with oxygen therapy.

Option A typically causes chronic symptoms, not sudden onset.

Option B does not cause respiratory distress.

Option C does not explain the environmental exposure or oxygen response.

NREMT emphasizes recognizing environmental hazards and removing patients from the source while providing supportive care.

The correct answer is B. Place padding under the torso only.

Key Pediatric Anatomical Difference:

Children (especially under ~8 years old) have a larger occiput (back of the head) relative to their body. When lying flat on a backboard:

The head is naturally pushed forward (flexed position)

This can compromise the airway and spinal alignment

Correct Technique:

To achieve a neutral airway and spinal alignment:

Padding is placed under the torso (shoulders/back)

This raises the body and allows the head to fall into a neutral position

NREMT-aligned guidance states:

“Due to a larger occiput, pediatric patients may require padding under the torso to maintain a neutral airway.”

“Avoid placing padding under the head alone, as this worsens flexion.”

Why the other options are incorrect:

A. Padding under the head only→ Worsens neck flexion, potentially compromising airway

C. Padding under both head and torso→ Unnecessary and may misalign the spine

D. No padding→ Leaves the head in a flexed, non-neutral position

Exact Extracts (NREMT-aligned EMT educational references):

“Children have a proportionally larger head, causing flexion when supine.”

“Padding under the torso helps achieve neutral alignment.”

“Maintain neutral in-line stabilization during immobilization.”

Clinical Priority Summary:

Because pediatric patients naturally fall into neck flexion on a backboard, placing padding under the torso restores neutral alignment, making B the correct answer.

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.
