NREMT EMT Online Access

Using the START triage system, patients are categorized based on Respirations, Perfusion, and Mental Status (RPM).

A respiratory rate greater than 30 breaths per minute immediately qualifies the patient as RED (Immediate). Additionally, delayed capillary refill (>2 seconds) further supports this classification.

Option A is correct.

Option B applies to stable patients who can wait.

Option C is for deceased or nonsalvageable patients.

Option D is for minor injuries.

NREMT teaches that patients with compromised airway or perfusion are the highest priority.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Nerve agents are highly toxic organophosphate chemicals that inhibit acetylcholinesterase, leading to excess acetylcholine accumulation and life-threatening cholinergic effects. NREMT hazardous materials education highlights recognition of these agents due to their rapid lethality.

Option C (Tabun) and D (Sarin) are correct. Both are internationally recognized nerve agents historically used in chemical warfare and terrorist attacks.

Option A (Naloxone) is an opioid antagonist, not a nerve agent.

Option B (Metoprolol) is a beta-blocker medication.

Option E (Atropine) is not a nerve agent; it is an antidote used to treat nerve agent poisoning.

NREMT emphasizes scene safety, recognition of toxidromes, and early antidote administration for nerve agent exposure.

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.

Febrile seizures most commonly occur in children between 6 months and 5 years of age. NREMT pediatric education emphasizes that seizures in infants younger than 6 months are not considered simple febrile seizures and should raise immediate concern for serious central nervous system infection.

Option C is correct because this patient is only 2 months old, placing them outside the typical age range for febrile seizures. Additionally, the presence of a petechial rash, lethargy, hypotension, and fever strongly suggests meningitis or sepsis, both of which are life-threatening.

Option A is incorrect because fever alone does not confirm febrile seizure.

Option B is incorrect because lack of medical history does not exclude serious infection.

Option D is partially true but not the most accurate or distinguishing reason.

NREMT stresses early recognition of meningitis, rapid transport, and aggressive supportive care due to high mortality risk in infants.
