NREMT EMT - Emergency Medical Technicians Exam

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.

Subcutaneous emphysema following blunt chest trauma strongly suggests air leaking from the lung into surrounding tissues, often associated with pneumothorax. NREMT trauma priorities stress that airway and breathing take precedence over all other interventions.

Option D is correct because the child is already in moderate respiratory distress, indicating inadequate ventilation. Assisting ventilations with a BVM ensures oxygen delivery and adequate tidal volume while preparing for rapid transport.

Option A is important but does not address the immediate life threat.

Option B may help with pain or flail segments but does not correct ventilation.

Option C is no longer routinely indicated and does not address breathing.

NREMT emphasizes correcting life-threatening airway and breathing problems before movement or transport.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Neurogenic shock results from damage to the spinal cord, most commonly at or above the thoracic level. NREMT education emphasizes that this injury disrupts the sympathetic nervous system, which normally maintains vascular tone.

Option C is correct because loss of sympathetic tone leads to widespread vasodilation, causing hypotension and often bradycardia, distinguishing neurogenic shock from other shock types.

Option A is incorrect because acetylcholine inhibition is not the mechanism.

Option B describes cardiogenic shock.

Option D describes septic (distributive) shock.

NREMT highlights that recognizing neurogenic shock is critical, as treatment priorities differ from hypovolemic shock.

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.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Upon arrival, EMTs must immediately perform a scene size-up, which focuses on safety and incident management rather than patient treatment.

Option A (Identifying hazards) is correct because recognizing dangers such as traffic, fire, violence, or hazardous materials is essential to prevent responder injury.

Option E (Requesting additional resources) is correct because early recognition of the need for more personnel, ALS support, fire services, or law enforcement improves patient outcomes and scene control.

Option B is incorrect because ruling out life threats occurs during the primary assessment, not immediately upon arrival.

Option C is incorrect because patient treatment must wait until scene safety is confirmed.

Option D is incorrect because PPE use is a personal responsibility, not a primary scene-arrival task.

NREMT stresses that effective EMS operations begin with safety, situational awareness, and resource management.

Comprehensive and Detailed Explanation (Based on NREMT standards):

The healthcare provider is ultimately responsible for maintaining certification, licensure, and continuing education requirements. While agencies, supervisors, and training officers may assist or provide opportunities, NREMT clearly states that responsibility rests with the individual EMT.

Option C is correct because failure to meet certification requirements can result in expiration or revocation regardless of employer involvement.

Options A, B, and D are incorrect because these roles may support education but are not legally responsible for an individual provider’s compliance.

NREMT emphasizes professional accountability as a core expectation of EMS practice.

Comprehensive and Detailed Explanation From Exact Extract:

Altered mental status, combined with pale, cool, and clammy skin, is strongly suggestive of hypoglycemia (low blood sugar). Hypoglycemia is especially dangerous in diabetics who take insulin or oral hypoglycemics. The body's adrenergic response causes the "cool and clammy" presentation.

Hyperglycemia typically presents with warm, dry skin and develops more slowly. EMTs should administer oral glucose if the patient can swallow.

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.

Comprehensive and Detailed Explanation From Exact Extract:

This is a high-risk cardiac event due to unstable angina or possible myocardial infarction. The EMT should:

Administer oxygen if SpOâ‚‚ is <94%

Avoid nitroglycerin if systolic BP is <90 mmHg

Obtain a 12-lead ECG to identify ST-elevation MI (STEMI) and transmit it if trained and authorized

CPAP is indicated for pulmonary edema, and albuterol is for bronchospasm, neither of which applies here.

NREMT stroke management focuses on rapid identification and time-sensitive intervention, particularly for patients who may be eligible for thrombolytic therapy or endovascular treatment.

Option D (Time of first signs or symptoms) is critical. This determines the patient’s eligibility for treatments such as tissue plasminogen activator (tPA), which must be administered within a defined time window.

Option C (Patient’s denial of a headache) is also important because sudden, severe headache suggests hemorrhagic stroke, whereas its absence may support ischemic stroke. This information helps guide diagnostic urgency and treatment planning.

Option A is not immediately relevant prehospital.

Option B is administrative, not emergent.

Option E does not impact acute stroke management.

NREMT stresses the importance of early notification, accurate time history, and focused neurological reporting to improve stroke outcomes.
