EMT Exam Dumps : Emergency Medical Technicians Exam

Comprehensive and Detailed Explanation From Exact Extract:

The patient’sexcessively high respiratory rate (RR 50),hypoxia (SpO₂ 89%), anddecreased mental status(drowsiness) indicaterespiratory failure, which is theinability to maintain oxygenation or ventilation.

Respiratory distress: Increased effort but adequate compensation

Respiratory arrest: Complete absence of breathing

Respiratory alkalosis: Possible early finding, but not a condition diagnosis

This patient is tiring and losing the ability to ventilate effectively — a hallmark of failure.

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.

Comprehensive and Detailed Explanation From Exact Extract:

Mental statusreflects perfusion and oxygen delivery to thebrain, which is highly sensitive to hypoxia and hypercapnia. Even if respiratory rate and SpO₂ are normal, altered mental status suggests ineffective gas exchange or hypoperfusion.

Pulse oximetry may be falsely normal in CO poisoning or poor perfusion. Skin color is subjective and not as sensitive or specific as neurological status.
