10 free AEMT practice questions: Toxicology and Overdose Management

Intranasal and intramuscular only, with the other routes left to paramedics: These are the two routes most services train first, so they feel like the boundary, but the national scope of practice model gives the AEMT the vascular routes for naloxone as well.

Intravenous only once access exists, with intranasal saved for a refusal: Reaching for the established line is good clinical sense, but that is a preference rather than a limit, and nothing restricts the nasal route to a patient who might refuse.

Any route is in scope, though each dose needs online medical direction: Medical direction does govern a great deal of what an AEMT gives, so this sounds properly cautious, but naloxone runs on standing protocol in essentially every system that carries it.

Repeat the intranasal dose in the opposite nostril and reassess: Repeating a dose is reasonable when the first one was absorbed and simply was not enough, but both nostrils are packed with clot here, so the second dose lands on the same blocked mucosa as the first.

Conclude the cause is not an opioid and continue ventilation alone: A dose that produced nothing is real evidence and it should make you rethink, but the question is whether the drug reached the bloodstream at all, and nothing here says it did.

Wait a further ten minutes before repeating any naloxone dose: Waiting respects the fact that naloxone is not instant, and patience prevents over-reversal, but ten more minutes of a blocked route changes nothing about the amount of drug reaching the receptor.

Obtain a signature on the refusal form and clear the scene promptly: A signed refusal is the routine paperwork for a patient who declines care, so it feels like the whole job, but a signature alone records nothing about the re-sedation risk that makes this refusal different.

Leave a naloxone kit with the family and advise them how to use it: Community naloxone genuinely saves lives, and handing one over feels like doing something useful, but it substitutes a bystander with no equipment for the ventilation that is what actually keeps this patient alive.

Request law enforcement to hold the patient for a psychiatric evaluation: Overdose calls often do have a mental health thread, and a hold looks like a way to keep the patient safe, but this patient is alert and oriented and no finding here supports removing the right to decide.

Anticholinergic: This one matches on almost every line, which is exactly why it is the trap: dilated pupils, a fast heart, a hot patient, and an altered mental status all fit. The skin does not. Anticholinergic skin is hot and dry.

Cholinergic: poisoning is wet too, so the soaked skin pulls you here, but the rest of the picture runs backward. Cholinergic pupils are constricted and the heart rate is slow.

Sedative-hypnotic: A festival call with an unknown ingestion makes alcohol and benzodiazepines a fair guess, but those patients are quiet, slow, and hypotensive rather than agitated and hypertensive.

Opioid: The constricted pupils and the depressed patient are a real overlap, and this is the mix-up the exam wants, but opioid skin is normal and dry and an opioid patient does not pour secretions from every surface.

Anticholinergic: The name is one letter away and the mechanism is the mirror image, which is exactly why it gets picked. Anticholinergic patients are hot, dry, and dilated. This patient is the opposite in every one of those.

Sympathomimetic: The wet skin fits and the respiratory rate is fast, so the sped up group has some pull, but a sympathomimetic patient has dilated pupils and a racing heart, and this heart rate is 44.

Apply the automated external defibrillator and follow the advisory prompts: The rate is dangerously slow and the machine is right there, so reaching for it feels decisive, but that device analyzes a pulseless patient and has nothing to offer one who still has a pulse.

Give oral glucose for the weakness and monitor the mental status: Weakness and a slow answer do belong on the hypoglycemia list, and checking a glucose level is always fair, but the pressure and the rate here are explained by the drug the patient swallowed.

Give high-concentration oxygen and transport without vascular access: Oxygen and a short scene time are never wrong, and skipping the line saves a minute, but that line is how fluid gets in and how the paramedic gives a drug the moment they arrive.

Advise the family to watch for symptoms at home overnight: A normal examination makes home sound reasonable, and the family will often push for it, but the liver injury from acetaminophen shows up days later and the window to prevent it closes long before then.

Have the patient drink water to dilute the tablets before transport: Dilution feels like it should help and it is a common piece of folk first aid, but it does not reduce absorption and it adds vomiting risk to a patient you are about to move.

Give activated charcoal on scene and reassess the mental status: Charcoal does bind acetaminophen and the ingestion is recent, but it is rarely carried in the field now, it is a protocol decision rather than a default, and it never replaces transport.

The generator exhaust displaced enough oxygen in the room to cause hypoxia: Generator exhaust indoors does not meaningfully deplete the room's oxygen concentration over this timeframe: the danger comes from inhaled carbon monoxide binding hemoglobin, not from displaced ambient oxygen. This explanation also does not account for why the pulse oximeter itself reads normally in a hypoxic patient.

Hyperventilation from anxiety is producing a falsely elevated reading: Hyperventilation does not produce a falsely elevated pulse oximetry reading; a standard pulse oximeter has no mechanism affected by respiratory rate in this way. It also fails to explain why three unrelated coworkers share the identical finding.

The patients are in the early, compensated stage of shock: Compensated shock is a perfusion problem with a maintained blood pressure, not an explanation for a falsely normal oxygen saturation reading. It also does not fit three patients sharing headache, nausea, and confusion after a shared exposure.

Withhold charcoal because acetaminophen is not adsorbed by activated charcoal: A student who believes charcoal only works on certain 'classic' drugs may assume acetaminophen is an exception, but charcoal is effective when given within about an hour of ingestion, and this ingestion was 20 minutes ago, well inside that window, so timing, not the drug, is what matters here.

Give activated charcoal immediately without contacting medical control first: This is the right medication for the right situation given in the wrong sequence: the AEMT must obtain approval from medical control before giving charcoal, not without it.

Withhold charcoal because the patient's level of consciousness is decreased: This patient is alert, oriented, and speaking clearly, so a student defaulting to the standard 'altered mental status' contraindication is misreading the question rather than applying it: a decreased level of consciousness is a reason to withhold charcoal, but that finding is absent here.

Improvement confirms CO poisoning; reduce oxygen to titrate SpO₂: This reaches the right interpretation of the symptoms but then falls back on titrating oxygen to the SpO₂ reading, which is unreliable in carbon monoxide poisoning because the sensor cannot tell oxygen from carbon monoxide.

Normal SpO₂ rules out CO poisoning; consider psychogenic causes: A student who trusts a normal-looking SpO₂ over the clinical picture will wrongly rule out carbon monoxide, when the device is misled, not the diagnosis disproven, in this exact situation.

Normal SpO₂ confirms adequate oxygenation; discontinue oxygen: This treats the unchanged 99% reading as proof of adequate oxygenation and stops therapy, which is the same false-reassurance misconception the item is built to test; the question raises it deliberately.
