Part of the Medical Emergencies practice questions exam area.
This page holds 200 free practice questions for Chapter 28, Toxicology, covering routes of exposure and poison control, toxidromes, decontamination and activated charcoal, antidotes, opioid and sedative overdose, alcohol withdrawal, stimulants and hallucinogens, acetaminophen, salicylate, TCA, beta blocker, calcium channel blocker, digoxin, lithium, and iron overdoses, carbon monoxide, cyanide, and toxic gases, caustics, hydrocarbons, toxic alcohols, organophosphates, and bites, stings, envenomation, and plant and mushroom poisoning. They are written for paramedic and EMT students working through Nancy Caroline's Emergency Care in the Streets, 9th edition. Every question shows the correct answer with a short explanation as soon as you tap, so you learn while you test rather than waiting until the end.
Study it two ways: the 10 Question Blitz, a quick round where every right answer lights a siren and any misses lead into Lights & Sirens, a 5-in-a-row drill on that section, or the full 100-question test drawn at random from the whole chapter. After each test you get a score and a section-by-section breakdown. Progress on the full test is saved on your device, so you can stop and pick up later.
A poison is best defined as any substance that:
Answer: B. Harms body structure or function once it enters the body
Toxicity depends on dose, route, and the patient, so even water or prescribed drugs can poison. Legality and dependence describe drugs of abuse, not toxicity itself.
A 24-year-old man is agitated, hot, and diaphoretic with dilated pupils, HR 138, and BP 182/104. The most likely toxidrome is:
Answer: C. Sympathomimetic
Stimulation with sweating points to sympathomimetic toxicity such as cocaine or methamphetamine. Anticholinergic patients look similar but have hot, dry, flushed skin.
The first priority in managing any poisoned patient after scene safety is:
Answer: C. Airway, breathing, and circulation
Most poisoned patients die of airway loss, hypoventilation, or shock, and supportive care saves more lives than antidotes. Identifying the toxin comes after the ABCs are secured.
Most students use the 10 Question Blitz for daily practice and take the full 100-question test in the days before a class exam or NREMT practice. Lights & Sirens after a blitz is the fastest way to close gaps the night before a test.
Every question in this chapter is also listed by section, with answers, on the topic pages above. See all paramedic topics or take the NREMT paramedic practice test.
