NREMT EMT Online Access

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:

Thepatient’s complaint of difficulty breathingis anairway/breathing issueand takes precedence over a controlled extremity bleed. The first action is toadminister oxygenand evaluate respiratory effort.

Though reassessing the wound is important,oxygenation is the prioritywhen airway compromise or respiratory distress is present. Tourniquets are foruncontrolled bleeding, which is not the case here.

Comprehensive and Detailed Explanation From Exact Extract:

Children compensate for shock through increasedheart rate,respiratory rate, andvasoconstriction, which delays blood pressure drop. Therefore:

Tachycardiais often thefirst sign

Prolonged capillary refill(>2 seconds) is an early indicator

Tachypneasupports perfusion

Blood pressureis alate signin pediatric shock. SpO₂ is helpful but does not specifically indicate shock. Blood glucose may be abnormal in other metabolic conditions but is not an early marker of volume loss.
