EMT Exam Dumps : Emergency Medical Technicians (EMT002) Exam

Comprehensive and Detailed Explanation From Exact Extract:

Contraindications to CPAP (Continuous Positive Airway Pressure) include:

Hypotension: CPAP can reduce preload and worsen shock (BP < 90 systolic is a contraindication)

Respiratory rate too low: A rate of 10 is at the low threshold; CPAP requires spontaneous adequate effort

Active vomiting or nausea: CPAP increases aspiration risk

Crackles and hypoxia are indications, not contraindications, for CPAP. Pulse rate does not influence CPAP use directly.

The cerebrum is the largest and most developed part of the human brain and is responsible for higher cognitive functions. According to NREMT anatomy and physiology education, the cerebrum controls thinking, reasoning, memory, judgment, voluntary movement, and sensory interpretation.

Option B is correct because conscious thought, problem-solving, and decision-making all originate in the cerebrum.

Option A (Pons) helps regulate breathing and sleep cycles.

Option C (Brain stem) controls vital functions such as heart rate, breathing, and blood pressure.

Option D (Cerebellum) coordinates balance, posture, and fine motor movement.

Understanding brain function helps EMTs correlate neurological findings with possible injuries or medical conditions.

Heat exhaustion results from prolonged exposure to elevated temperatures, leading to fluid and electrolyte loss (especially sodium and water), causing hypovolemia. This can result in:

Tachycardia

Weakness

Dizziness

Profuse sweating

Unlike heat stroke, mental status is typically preserved in heat exhaustion. Hypertension and bradycardia are not characteristic.
