Free Practice Questions for NREMT EMT Exam

The foundation of effective multiple-casualty incident (MCI) management is the Incident Command System (ICS). NREMT teaches that ICS provides clear leadership, communication, accountability, and coordination of resources.

Option D is correct because ICS allows for scalable management, efficient delegation, and integration of multiple agencies.

Option B is important but is a component of ICS, not the core principle.

Option C is a tactical step that occurs within the command structure.

Option A misunderstands ICS, as command is established based on arrival, not rank alone.

NREMT stresses that without ICS, MCIs become chaotic and unsafe, regardless of clinical skill.

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).

Comprehensive and Detailed Explanation From Exact Extract:

This is a classic presentation of hypovolemic shock due to traumatic blood loss (open femur fracture, pelvic instability). Indicators include:

Low BP (86/42) = hypotension

High pulse (P 136) = compensation

Mental status decline (responsive only to voice) = indicates decompensated shock

Obstructive and distributive shock are not applicable. Compensated shock would show normal BP and alert mental status.

The START (Simple Triage and Rapid Treatment) system classifies patients based on ability to walk, respirations, perfusion, and mental status. A patient with an open fracture who can breathe adequately, has a pulse, and follows commands is categorized as “Delayed”.

Immediate (Red) is reserved for those who cannot walk and have life-threatening conditions, such as compromised airway or severe bleeding.

NREMT guidelines clearly state that life-threatening danger overrides spinal motion restriction. This patient shows signs of a spinal cord injury (loss of movement and sensation), but they were previously trapped under a vehicle—an inherently unstable and dangerous environment.

Option A is correct because the clothes drag is an emergency move designed to remove a patient from immediate danger as quickly as possible. In emergency situations, speed and rescuer safety take priority over spinal immobilization.

Option B is incorrect because clothes drags do not minimize spinal movement.

Option C is incorrect because preparing and using a long backboard delays removal.

Option D is incorrect because spinal protection is secondary to immediate life threats.

NREMT emphasizes: “You cannot help the patient if you become injured.”

When an incident involves multiple agencies with shared responsibility, NREMT teaches that a Unified Command structure is used. This allows police, fire, EMS, and other agencies to work together under a common set of objectives while maintaining their individual authority.

Option C is correct because the defining feature of unified command is multi-agency involvement, not rank or arrival order.

Option A is incorrect because no single agency automatically has authority.

Option B misunderstands unified command, which still functions with coordinated leadership.

Option D is incorrect because EMS does not automatically become part of command.

NREMT emphasizes unified command to improve coordination, communication, and safety during MCIs.

Comprehensive and Detailed Explanation From Exact Extract:

The legal concept of tort negligence in EMS requires the plaintiff to establish four elements:

Duty to act

Breach of that duty

Damages (harm caused)

Causation — a direct link between the EMT’s action/inaction and the harm caused

Causation (often termed “proximate cause”) is the essential element that connects the EMT’s breach to the patient's injury or outcome. Abandonment, assault, and false imprisonment are other intentional torts, but not core elements of proving negligence.

Comprehensive and Detailed Explanation From Exact Extract:

Negligence occurs when an EMT:

Has a duty to act

Breaches that duty (e.g., by withholding basic care like warmth)

Causes harm or risk of harm

Establishes causation

The EMT’s failure to treat the patient with respect and dignity — even if the patient improved — still constitutes negligence, especially if tied to a discriminatory or dismissive attitude.

Comprehensive and Detailed Explanation From Exact Extract:

Sickle cell crisis (vaso-occlusive crisis) occurs when abnormally shaped red blood cells obstruct blood flow, leading to:

Severe localized or generalized pain (most common symptom)

Often in the back, chest, abdomen, or long bones

Hypoxia may be a contributing factor, but pain is the most reported reason for EMS activation. Cardiac arrhythmias and hypertension are not primary symptoms of sickle cell crisis.
