Free NREMT EMT Practice Exam with Questions & Answers | Set: 6

If a choking patient becomes unresponsive, EMTs should:

Check for a pulse

Begin chest compressions if no pulse is foundChest compressions can help dislodge the object. After compressions, the airway should be opened and inspected. Back blows are not appropriate for unconscious patients.

Ventilation is attempted after clearing the airway or if no object is seen. Do not withhold compressions waiting for object removal.

Comprehensive and Detailed Explanation (Based on NREMT standards):

The patient’s signs—hip pain, deformity, and leg shortening—are consistent with a proximal femur or hip fracture. NREMT trauma care emphasizes immobilization, pain reduction, and prevention of further injury.

Option C (Apply mild traction) is appropriate to reduce muscle spasm and pain when a femur fracture is suspected and no contraindications are present.

Option D (Splint with blankets and pillows) is correct because soft splinting stabilizes the injury and limits movement during transport.

Option A is not required because oxygen saturation is adequate.

Option B is contraindicated because leg elevation may worsen pain or bleeding.

Option E is reserved for unstable pelvic fractures, not isolated hip fractures.

NREMT emphasizes gentle handling, immobilization, and rapid transport for suspected hip fractures.

The correct answer is D. Ensure that secondary triage is completed.

Role of Treatment Supervisor in MCI (Mass Casualty Incident):

In the Incident Command System (ICS), responsibilities are divided:

Triage Supervisor → performs initial triage

Treatment Supervisor → manages patient care after triage

Transport Supervisor → coordinates transport to hospitals

Staging Officer → manages personnel/equipment staging

Primary responsibility of Treatment Supervisor:

Oversee treatment areas (Immediate, Delayed, Minor)

Ensure patients are reassessed and re-triaged (secondary triage)

Monitor patient conditions and prioritize care

NREMT-aligned guidance states:

“The treatment supervisor is responsible for patient care and reassessment.”

“Secondary triage is performed in the treatment area.”

Why D is correct:

Secondary triage ensures patients are:

Reevaluated

Properly prioritized as conditions change

This is a core responsibility of the treatment supervisor

Why the other options are incorrect:

A. Command triage personnel→ Responsibility of the Triage Supervisor

B. Establish staging area→ Responsibility of the Staging Officer

C. Coordinate transportation→ Responsibility of the Transport Supervisor

Exact Extracts (NREMT-aligned EMT educational references):

“Treatment unit is responsible for treatment and secondary triage.”

“Transport officer coordinates patient movement to hospitals.”

“Staging manages resources and personnel.”

Clinical Priority Summary:

The treatment supervisor’s primary role is to manage patient care and ensure ongoing reassessment, including secondary triage, making D the correct answer.

The correct answer is B. Femur.

Why B is correct (Femur):

A fracture of the femur, especially the proximal femur (hip region), commonly results in:

External rotation of the affected leg

Shortening of the limb

This occurs because:

Strong muscles (particularly the hip external rotators) pull on the fractured bone

The limb naturally falls into an externally rotated position

NREMT-aligned trauma guidance states:

“Femur fractures often present with shortening and external rotation of the leg.”

“Muscle spasms and bone displacement alter normal limb alignment.”

Why the other options are incorrect:

A. Pubis: Pelvic fractures may cause pain and instability but do not typically cause isolated external rotation of the leg.

C. Patella: Affects the knee; does not cause external rotation of the entire leg.

D. L5 vertebra: Spinal injury; may cause neurologic deficits but not limb rotation.

Exact Extracts:

“Femur fractures commonly result in limb shortening and external rotation.”

“Muscle forces acting on the fractured femur alter positioning of the leg.”

“Assessment includes observing deformity and abnormal limb positioning.”

The correct answer is B. Abrasion.

An abrasion is a superficial injury caused by scraping or rubbing force that damages the epidermis (outer layer of skin). This type of injury is commonly referred to as a “scrape” or “road rash.”

Why B is correct:

Abrasions occur when the skin is rubbed or scraped against a rough surface.

They involve only the epidermis and are usually superficial.

Minimal bleeding may occur, but the main concern is pain and risk of infection.

Why the other options are incorrect:

A. Avulsion → Involves tearing away of skin or tissue, often deeper and more severe

C. Puncture → Caused by a sharp, pointed object penetrating the skin

D. Laceration → A cut or tear in the skin, typically deeper than an abrasion

Exact Extracts:

“An abrasion is a wound caused by scraping or rubbing of the skin.”

“It involves damage to the epidermis.”

“Abrasions are usually superficial but can be painful and prone to infection.”

The correct answer is D. 60 seconds.

This question is testing the special consideration of hypothermia in cardiac arrest assessment. In a patient found unresponsive in the snow, there is a high likelihood of severe hypothermia, which significantly slows metabolism and heart rate.

In hypothermic patients, pulses may be very slow and difficult to detect, so the EMT must take extra time to accurately determine whether a pulse is present before initiating CPR.

Standard pulse checks in normothermic patients are limited to no more than 10 seconds, but hypothermic patients are an exception.

Why 60 seconds is correct:

NREMT-aligned EMS guidelines emphasize that in severe hypothermia, the provider should assess the pulse for up to 60 seconds before concluding that the patient is pulseless. This is because hypothermia can produce extremely slow heart rates (bradycardia), and premature CPR could be inappropriate if a pulse is actually present.

Why the other options are incorrect:

A. 10 seconds: This is correct for standard cardiac arrest assessment in normothermic patients, but not for hypothermia.

B. 15 seconds and C. 30 seconds: These are not recommended durations in NREMT or AHA guidelines for pulse checks.

Exact Extracts:

“In a hypothermic patient, check the pulse for 30–60 seconds before determining pulselessness.”

“Severely hypothermic patients may have very slow heart rates that are difficult to detect.”

“Do not assume cardiac arrest until a careful and prolonged pulse assessment has been performed.”

Compared to adults, pediatric patients have:

A proportionately larger tongue, which increases the risk of airway obstruction

A larger occiput, which causes natural neck flexion when lying supine, potentially occluding the airway

This anatomical difference is why EMS providers often use a shoulder roll instead of a head tilt to maintain a neutral airway in infants and toddlers.

NREMT medication management standards require EMTs to ensure that all medications are stored properly and are safe for administration. The presence of ice crystals indicates that a medication has frozen, which can alter its chemical stability, concentration, and effectiveness.

Option C is correct because medications that have frozen must be discarded and replaced, even if they later thaw. Freezing can cause separation of active ingredients or damage to the medication vial or syringe.

Option A is insufficient because expiration status does not address medication integrity.

Option B is incorrect because frozen medications are unsafe and should not be reused.

Option D is dangerous and explicitly prohibited, as warming does not restore medication safety.

NREMT emphasizes strict medication safety checks to prevent patient harm and ensure effective treatment.

The correct answer is C. Deep vein thrombosis (DVT).

This question is testing recognition of classic signs and symptoms of a deep vein thrombosis, which is a blood clot forming in a deep vein, most commonly in the lower extremities.

The patient presents with hallmark findings:

Unilateral calf pain (cramping/soreness)

Swelling (one calf larger than the other)

Redness

Warmth to the touch

These findings strongly indicate DVT.

According to NREMT-aligned EMT educational material:

“Signs of deep vein thrombosis include swelling, pain, warmth, and redness of the affected extremity.”

“DVT most commonly occurs in the legs and may present with unilateral swelling.”

Why the other options are incorrect:

A. Hyperthermia:A systemic condition involving elevated body temperature, not localized calf swelling and pain.

B. Food poisoning:Causes gastrointestinal symptoms such as nausea, vomiting, and diarrhea, not localized extremity findings.

D. Compartment syndrome:Typically presents with severe pain (often out of proportion), decreased pulses, pallor, paresthesia, and paralysis—not primarily redness and warmth. It is usually associated with trauma.

Clinical significance (important NREMT concept):

DVT is dangerous because the clot can dislodge and travel to the lungs, causing a pulmonary embolism, which is life-threatening.

NREMT guidance:

“A thrombus in a deep vein may dislodge and travel to the lungs, causing a pulmonary embolism.”

Exact Extracts:

“Signs of deep vein thrombosis include swelling, pain, warmth, and redness.”

“DVT most often affects the lower extremities.”

“A thrombus can break free and become an embolus, traveling to the lungs.”

Albuterol, a common beta-2 adrenergic agonist used in inhalers, stimulates bronchial smooth muscle relaxation. However, stimulation of beta receptors can also produce systemic effects such as:

Tachycardia (due to beta-1 cross-reactivity)

Nervousness (from central stimulation)

Coughing (a local airway response)

Confusion and drowsiness are not typical side effects of beta-agonists. Hypotension is rare unless severe overdose occurs.
