Free Practice Questions for NREMT EMT Exam

NREMT distinguishes mild versus severe airway obstruction primarily by the patient’s ability to move air. In a mild obstruction, the patient can cough forcefully, speak, and exchange air. A severe obstruction occurs when airflow is critically impaired.

Option A (Ineffective cough) is the key indicator that a mild obstruction has progressed to a severe one. An ineffective or silent cough means the patient can no longer generate enough airflow to clear the obstruction, placing them at imminent risk of hypoxia and cardiac arrest.

Option B is a late sign of hypoxia but does not define severity of obstruction.

Option C is not specific to airway obstruction severity.

Option D indicates a mild obstruction, not severe.

NREMT teaches that once a cough becomes ineffective, immediate airway intervention is required.

Pulmonary edema is caused by fluid accumulation in the alveoli, impairing gas exchange. It is typically due to:

Left-sided heart failure: Blood backs up into the pulmonary circulation

Hypertensive crisis: Increases hydrostatic pressure in the lungs

Anaphylaxis causes vasodilation and bronchospasm, not fluid overload. Increased oncotic pressure would retain fluid in capillaries — the opposite of edema.

The correct answer is B. Ventricular tachycardia only.

There are two primary shockable rhythms in cardiac arrest:

Ventricular fibrillation (VF)

Ventricular tachycardia (VT)

However, only one of these may still produce a pulse under certain conditions.

Why B is correct:

Ventricular tachycardia (VT) can occur with or without a pulse.

In some cases, VT allows the heart to generate enough cardiac output to produce a palpable pulse (this is called stable or unstable VT with a pulse).

Therefore, VT is the only shockable rhythm that may still have a pulse.

Why the other options are incorrect:

A. Ventricular fibrillation only → VF produces no organized cardiac activity, therefore no pulse

C. Both shockable rhythms → Incorrect because VF never produces a pulse

D. Neither a shockable rhythm → Incorrect because VT can produce a pulse

Exact Extracts:

“Ventricular fibrillation results in no effective cardiac output and no pulse.”

“Ventricular tachycardia may be present with or without a pulse.”

“Pulseless ventricular tachycardia and ventricular fibrillation are treated with defibrillation.”

The correct answer is D. Muscle cramps.

Hemodialysis is a process that removes waste products and excess fluid from the blood in patients with kidney failure. During this process, rapid shifts in fluid and electrolytes can lead to several complications.

One of the most common adverse effects during hemodialysis is muscle cramps, which are primarily caused by:

Rapid fluid removal (hypovolemia)

Electrolyte imbalances

Changes in osmolarity

Why D is correct:

NREMT-based medical guidelines highlight that:

“Patients undergoing dialysis commonly experience complications such as hypotension and muscle cramping.”

Muscle cramps are frequently reported during or immediately after dialysis due to fluid shifts.

Why the other options are incorrect:

A. Tinnitus: Not associated with dialysis treatment.

B. Gallstones: A chronic condition unrelated to dialysis sessions.

C. Hypertension: While kidney patients may have hypertension, dialysis more commonly causes hypotension, not hypertension, during treatment.

Exact Extracts:

“Complications of dialysis include hypotension and muscle cramps.”

“Rapid fluid shifts during dialysis can result in painful muscle cramping.”

“Dialysis patients may experience electrolyte imbalances leading to neuromuscular symptoms.”

NREMT hemorrhage-control education emphasizes wound packing for severe external bleeding that cannot be controlled with direct pressure or a tourniquet, particularly in junctional areas. Junctional areas are regions where tourniquets are ineffective due to proximity to the torso.

Option B (Left axilla) is correct. The axilla is a classic junctional site where major vessels are present and tourniquets cannot be applied effectively.

Option A (Left hip) is correct because wounds near the inguinal region are considered junctional and are appropriate for wound packing.

Option C (Left shoulder) is also considered a junctional area where wound packing may be used if bleeding is severe and not amenable to tourniquet placement.

Option D (Right temple) is incorrect because wound packing is contraindicated in the skull.

Option E (Right forearm) is incorrect because tourniquets are preferred on extremities.

Option F (Right upper abdominal quadrant) is incorrect because wound packing is not performed in the abdominal cavity.

NREMT stresses early hemorrhage control as a top trauma priority due to preventable death from bleeding.

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.

The correct answers related to increased epinephrine (adrenergic response) are C. Diaphoresis and D. Tachycardia. However, since the question asks for three, the closest additional adrenergic-related symptom is A. Dizziness (though it is less specific and may overlap with neuroglycopenic effects).

Understanding the concept:

Hypoglycemia produces two categories of symptoms:

These occur due to activation of the sympathetic nervous system:

Diaphoresis (sweating)

Tachycardia

Anxiety, tremors, pallor

These include:

Drowsiness

Disorientation

Unresponsiveness

Why the correct answers are:

C. Diaphoresis → CorrectClassic adrenergic response caused by epinephrine release

D. Tachycardia → CorrectDirect effect of sympathetic stimulation

A. Dizziness → Acceptable/closest thirdCan occur early and may be associated with sympathetic activation, though less specific

Why the other options are incorrect:

B. Drowsiness → Neuroglycopenic

E. Disorientation → Neuroglycopenic

F. Unresponsiveness → Severe neuroglycopenia

Exact Extracts:

“Early hypoglycemia triggers epinephrine release causing sweating and tachycardia.”

“Adrenergic symptoms include diaphoresis, tachycardia, and anxiety.”

“Neuroglycopenic symptoms include confusion, drowsiness, and unresponsiveness.”

The correct answer is C. Providing high-flow oxygen via non-rebreather mask.

This patient is showing clear signs of moderate to severe respiratory distress, including:

Tachypnea (respiratory rate of 28)

Accessory muscle use

Cool, clammy skin (indicating increased work of breathing and possible hypoxia)

According to NREMT airway and ventilation guidelines, patients in respiratory distress who are still breathing adequately should receive high-concentration oxygen, typically via a non-rebreather mask at 10–15 L/min.

Why C is correct:

NREMT educational standards emphasize that in patients with adequate breathing but signs of distress, the appropriate intervention is:

“Administer high-flow oxygen to patients with signs of hypoxia or respiratory distress.”

A non-rebreather mask delivers the highest oxygen concentration without assisting ventilations, making it ideal for this scenario.

Why the other options are incorrect:

A. Nasal cannula: Provides low-flow oxygen and is insufficient for moderate to severe respiratory distress.

B. Oropharyngeal airway: Indicated only for unresponsive patients without a gag reflex, which is not the case here.

D. CPAP: Typically indicated for pulmonary edema or COPD exacerbations with signs of respiratory failure; asthma is a relative contraindication in many EMT-level protocols and is not first-line in this presentation.

Exact Extracts:

“Administer oxygen via nonrebreather mask to patients with adequate breathing and signs of respiratory distress.”

“Patients with increased work of breathing and tachypnea require high-concentration oxygen.”

“Oropharyngeal airways are indicated for unresponsive patients without a gag reflex.”

Hypovolemic shock results from acute blood loss, commonly seen with penetrating trauma such as gunshot wounds. NREMT identifies several key indicators that reflect reduced circulating volume and inadequate tissue perfusion.

Option A (Heart rate) is a strong indicator. Tachycardia (P 140) reflects the body’s attempt to compensate for reduced blood volume and maintain cardiac output.

Option B (Lung sounds) are significant in this case because absent sounds suggest associated chest trauma that may contribute to blood loss and impaired oxygenation, worsening shock.

Option C (Mental status) is a critical indicator. Unconsciousness reflects inadequate cerebral perfusion, a late and serious sign of shock.

Additional supportive findings include pale, cool skin and borderline hypotension. NREMT emphasizes early recognition of shock and rapid control of bleeding, oxygenation, and transport to definitive care.

Personal injury prevention supplies are designed to protect EMS providers from physical injuries, rather than infection.

Option C (Pair of leather gloves) is correct because leather gloves protect against cuts, abrasions, and puncture injuries during rescue operations such as vehicle extrication.

Option D (N95 respirator) is personal protective equipment (PPE) for infection control, not injury prevention.

Option A and B are related to biohazard handling and decontamination.

NREMT differentiates PPE from injury-prevention equipment to ensure proper risk management.
