EMT Exam Dumps - NREMT Medical Technicians Questions and Answers

Comprehensive and Detailed Explanation From Exact Extract:

Mechanism of Injury (MOI)assessment is a cornerstone of trauma care. It helps providers determine:

Extent of injury: High-speed collisions, falls from height, or penetrating trauma suggest internal injuries even if external signs are limited.

Need for additional resources: MOI may indicate the necessity ofALS backup,air transport, ortechnical rescue.

MOI cannot determine a patient’smedical historyor guarantee survival predictions. Thedestination facilitydepends on multiple factors including triage protocols, vital signs, and local trauma system regulations.

Thereassessment phasein the EMT patient assessment model starts with repeating theprimary survey(also called the primary assessment), which includes:

Airway

Breathing

Circulation

Disability (mental status)

Exposure/environment

The purpose is to identify any changes or deterioration in the patient’slife-threatening conditions, especially in dynamic or unstable patients. Only after this do EMTs check vitals and reevaluate secondary complaints.

Comprehensive and Detailed Explanation From Exact Extract:

Negligenceoccurs when an EMT:

Has aduty to act

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

Causesharm or risk of harm

Establishescausation

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

In patients with asthma experiencing respiratory failure, improper ventilation (especially excessive rates) can lead to air trapping and increased intrathoracic pressure, reducing venous return and worsening hypotension. Thecorrect techniqueis to ventilate slowly to allow full exhalation — around1 breath every 5–6 secondsfor adults.

CPAPis contraindicated in unresponsive patients who cannot maintain their own airway. Anon-rebreather maskwould be insufficient for an unresponsive patient, andforceful ventilationrisks barotrauma.

Laundry detergent ingestion — especially in the case ofliquid detergent pods— is associated withcaustic airway and gastrointestinal injuries. The presence ofcracklesanddrowsinessare signs of aspiration and possiblerespiratory failure. Vomiting increases the risk ofaspiration pneumonitis, andesophageal perforationis a life-threatening complication from corrosive ingestion.

While seizure and hypoglycemia are possible complications of toxic ingestion, they are not as immediately linked to the detergent profile as airway injury and aspiration risk.

Comprehensive and Detailed Explanation From Exact Extract:

CPAPworks by delivering continuous positive pressure to keep alveoli open and improve oxygenation. However, complications include:

Hypotension: Due to reduced venous return and cardiac preload

Feeling of suffocation: Common psychological reaction to a tight-fitting mask and forced airflow

It isused to treat, not cause, pulmonary edema. It doesnot induce bronchospasmor myocardial infarction.

Comprehensive and Detailed Explanation From Exact Extract:

This is ahigh-risk cardiac eventdue to unstable angina or possiblemyocardial infarction. The EMT should:

Administer oxygenif SpO₂ is <94%

Avoid nitroglycerinif systolic BP is <90 mmHg

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

CPAP is indicated forpulmonary edema, and albuterol is forbronchospasm, neither of which applies here.

EMS professionals are expected to useempathetic yet clear languagewhen communicating a death. The phrase"She has passed"is bothrespectfuland commonly accepted as an appropriate way toconvey death compassionatelywithout being overly clinical or harsh.

“Died” may sound too blunt in an emotional moment, while “didn’t make it” and “at peace” can feelvague or dismissive. Clear, empathetic communication is critical for patient dignity and family support during death notifications.
