EMT Exam Dumps : Emergency Medical Technicians Exam

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.

Comprehensive and Detailed Explanation From Exact Extract:

Forsuspected or confirmed tuberculosis (TB), the EMT should place asurgical mask on the patient, not a HEPA respirator. Surgical masks are used tocontain droplets from the patientand reduce airborne transmission.

The EMTshould wear aN95 or HEPA respiratorto protect against inhaling airborne particles. Notification to the CDC is not the EMT’s responsibility — that falls to public health officials.

Comprehensive and Detailed Explanation From Exact Extract:

Perfusionrefers to delivery of oxygen and nutrients to tissues. It depends on three essential components:

Patent airway: Ensures oxygen reaches lungs

Intact microcirculation: Capillary-level exchange must function

Sufficient blood volume: Maintains blood pressure and oxygen transport

Hypoxic drive relates toCOPD physiology, not perfusion.High alveolar pressure(like from CPAP) mayimpede venous return, and alow ventilation-perfusion ratiomeans poor oxygenation efficiency, which negatively affects perfusion.
