NREMT — EMT & Paramedic
NREMT Medical Emergencies Practice Questions (Neuro, Diabetic, Anaphylaxis)
The medical-emergencies bank rewards pattern recognition with a clock attached: stroke has a treatment window, hypoglycemia has a 'fix it now' answer, anaphylaxis has exactly one first-line drug. The NREMT writes these stems to see whether you (a) recognize the syndrome from scattered findings, (b) take the immediately available corrective action, and (c) avoid the classic confusions — stroke vs hypoglycemia being the most planted.
Two cross-cutting rules: check a glucose on every altered patient where scope/protocol allow, because hypoglycemia imitates everything; and note the time — last known well for stroke, onset for seizures and reactions — because destination decisions ride on it.
Neuro: stroke, seizures, and the glucose imposter
Stroke: sudden focal deficits — facial droop, arm drift, abnormal speech (the Cincinnati triad), plus gaze deviation, neglect, or sudden severe headache (think hemorrhagic). The tested actions: perform a validated stroke scale, establish last known well time from witnesses, check glucose (hypoglycemia is the great mimic and is correctable), protect the airway, do not give anything by mouth, and transport rapidly to an appropriate stroke center with prenotification — the entire prehospital job is recognition, timestamp, and speed. Severity tools (e.g., LVO screens) may route patients to thrombectomy-capable centers per local protocol.
Seizures: active seizure care is protective — nothing in the mouth, protect the head, time it; postictal patients need airway positioning, suction readiness, oxygen as indicated, glucose check, and search for causes (missed medications, fever in children, trauma, eclampsia in late pregnancy). Status epilepticus — continuous or repeating seizures without recovery — is a true emergency: aggressive airway support and rapid ALS (benzodiazepines at the medic level per protocol).
Diabetic emergencies and anaphylaxis
Hypoglycemia: rapid onset, sweaty cool skin, tachycardia, bizarre behavior, combativeness, seizures or coma — fixed with oral glucose only if the patient is awake enough to protect their airway and swallow (EMT level) or parenteral routes at ALS level per protocol. Hyperglycemia/DKA: gradual onset over days — polyuria, polydipsia, warm dry skin, deep rapid (Kussmaul) respirations, fruity breath, dehydration; field care is supportive with transport, because the fix (insulin, fluids, electrolytes) is a hospital process. The discriminator table — onset speed, skin wet vs dry, breathing pattern — is exam gold.
Anaphylaxis: an allergic reaction becomes anaphylaxis when it involves airway/breathing compromise (stridor, wheeze, tongue/lip swelling) or circulation (hypotension, syncope) — typically with hives/flushing, after an exposure. The answer is epinephrine IM, immediately — assisting with the patient's auto-injector at the EMT level per protocol, administering per standing order where authorized; antihistamines and steroids are adjuncts that never precede or replace epi. Delayed epinephrine is the most documented fatal error in real-world anaphylaxis, and the exam tests it relentlessly: 'severe reaction + something before epi' is always wrong. Be ready for the biphasic-reaction follow-up: symptoms can recur hours later, so all anaphylaxis gets transported.
Practice questions with answers & rationales
Q1. A 68-year-old woman has sudden right-arm weakness and slurred speech that started 'sometime this morning.' What three pieces of information most change her care?
Answer: A validated stroke-scale result (confirms the syndrome), the last-known-well time from a reliable witness (drives eligibility for time-dependent therapies and destination), and a glucose reading (hypoglycemia mimics stroke and is immediately correctable). With those, the job is rapid transport to an appropriate stroke center with prenotification, nothing by mouth, airway protected. 'Sometime this morning' is the exam's cue that you must pin the timestamp down.
Q2. Bystanders report a man 'acting drunk' — sweaty, combative, confused. He's a known diabetic. What's the trap and the correct sequence?
Answer: The trap is anchoring on intoxication or psychiatric behavior. Sweaty + altered + diabetic screams hypoglycemia: assess ABCs, check glucose, and if he's awake with an intact gag and able to swallow, oral glucose per protocol; if not, ALS for parenteral correction. Document behavior change after treatment. The 'drunk' presentation of hypoglycemia (and of head injury) is among the most repeated NREMT patterns.
Q3. When is oral glucose contraindicated for a hypoglycemic patient?
Answer: When the patient cannot protect their airway — unresponsive, unable to follow commands, no effective swallow/gag. Putting gel in an unprotected airway invites aspiration. Those patients need ALS routes (or, per some protocols, buccal placement variations — follow local protocol) and aggressive airway monitoring. The exam phrasing to watch: 'responds to painful stimuli' = not awake enough.
Q4. Differentiate DKA from hypoglycemia by onset, skin, and respirations.
Answer: Hypoglycemia: minutes to hours, cool and diaphoretic skin, normal-to-shallow breathing, with neuro/behavioral dominance. DKA: develops over days, warm dry skin with dehydration (poor turgor, thirst, polyuria), deep rapid Kussmaul respirations with fruity/acetone breath. Practical consequence: hypoglycemia is fixed in the field; DKA gets supportive care, fluids per ALS protocol, and transport. When in doubt — the glucometer settles it, which is why 'check glucose' is so often the credited answer.
Q5. A patient stung by a wasp has hives, lip swelling, and audible wheezing. He has his own epinephrine auto-injector. What's the EMT's action?
Answer: Help administer the epinephrine auto-injector immediately (lateral thigh, per protocol/medical direction) — airway involvement plus a known exposure is anaphylaxis, and epi is the only first-line treatment. Then oxygen as indicated, position per blood pressure, rapid transport, request ALS, and monitor for deterioration or a biphasic recurrence. Any answer placing an antihistamine, 'continued monitoring,' or a call for permission ahead of available epinephrine per protocol is the planted failure.
Q6. Why does every anaphylaxis patient get transported, even after dramatic improvement post-epinephrine?
Answer: Two reasons: epinephrine's effects wane within minutes-to-tens-of-minutes while antigen exposure may persist, and biphasic reactions can recur hours after full resolution. The improved patient who refuses transport is a documented fatality pattern. The exam tests this as a 'patient wants to sign out' scenario — the credited answer involves strong counseling toward transport and medical direction involvement.
Q7. Your patient seizes for 90 seconds, stops, then begins seizing again without waking. What is this and what changes?
Answer: Status epilepticus — recurrent seizures without regaining consciousness between them (or continuous seizing beyond about 5 minutes). It's no longer a protect-and-wait event: aggressive airway management (positioning, suction, NPA, ventilatory support as needed), oxygen, immediate ALS intercept/transport — benzodiazepines per medic protocol are the definitive prehospital therapy. Glucose check still applies: hypoglycemic seizures need sugar, not just suppression.
Common mistakes to avoid
- Skipping the glucose check on altered patients — hypoglycemia imitates stroke, intoxication, and psychiatric crises by design in NREMT stems.
- Failing to pin down last-known-well time, or accepting 'this morning' as an answer.
- Putting anything by mouth in patients who can't protect their airway (oral glucose, aspirin in stroke stems).
- Sequencing antihistamines, oxygen-and-monitor, or a permission call ahead of available epinephrine in anaphylaxis.
- Restraining or inserting objects during active seizures, or skipping the airway plan for the postictal phase.
- Letting the post-epi 'I feel fine' patient drive the disposition — biphasic reactions are the tested reason for transport.
