EMT medications for the NREMT, and what EMTs can't give

The EMT medication list is short, which is exactly why the NREMT tests it the way it does. You are rarely asked to recall a long table of drugs. You are asked whether a drug fits this patient, whether something in the history rules it out, and whether the drug is even within EMT scope. Many wrong answers on these items are perfectly good treatments that belong to the AEMT or paramedic level.

This guide covers the medications in Unit 16 of the free NREMT EMT course, which follows the National EMS Scope of Practice Model and, for detail, the Michigan statewide EMS protocols. Local protocols and medical direction govern actual practice. The national model is a guide for states, not a federal law, and the authority to give any drug comes from state rule plus your medical director's protocol. Where your program teaches something different, your program wins.

The EMT medication list at a glance

The rest of this post goes through them one at a time, with the scenario each one tends to appear in.

Oxygen and aspirin

Oxygen is the medication students over-give. The national model gives it to patients who are short of breath, hypoxemic or in heart failure, not to every patient with chest pain. A course scenario: a 58-year-old is alert with crushing chest pressure, SpO2 97% and no shortness of breath. The fitting answer is chewable aspirin, and oxygen is not routine here.

Aspirin is an antiplatelet agent for chest pain of suspected cardiac origin. The preferred form is a chewable, non-enteric-coated tablet, chewed, because chewing speeds absorption and enteric coating delays it. The Michigan protocol names hypersensitivity to NSAIDs as the reason to withhold it, and local protocols may add others. Aspirin is also deferred when the pain is probably not cardiac, such as a child with chest pain after falling onto the chest.

History matters here. If a chest-pain patient says she took her own aspirin 30 minutes ago, you tell medical direction and follow protocol rather than deciding on your own.

Oral glucose and nitroglycerin

Oral glucose is only for a conscious patient who can swallow and protect the airway. A diabetic patient with a glucose of 48 mg/dL who is confused but follows commands and can swallow gets oral glucose, then a recheck of mental status. An unresponsive diabetic patient does not. That patient needs IV dextrose or glucagon, which are AEMT-level and up, so the EMT supports the airway, gives oxygen, checks glucose and calls early for ALS. A hypoglycemic patient who has had a seizure is transported regardless of how well they respond.

Nitroglycerin is the classic scope trap. In the national model, the EMT may assist with the patient's own prescribed nitroglycerin for suspected ischemic chest pain; nitroglycerin from EMS stock is AEMT and up. It is a vasodilator, so its expected effects are lower blood pressure and relief of chest pain, with headache and flushing as common side effects. Two findings make you hold it:

• Hypotension. A chest-pain patient with a blood pressure of 88/60 does not get nitroglycerin, even her own. Hold it and notify medical control.
• A recent PDE-5 inhibitor, such as sildenafil. The national model and the Michigan protocol say to avoid nitroglycerin within 48 hours of one. This is why the medication question in the SAMPLE history matters, as the patient assessment walkthrough shows.

Epinephrine and naloxone

Epinephrine is first-line for anaphylaxis. Antihistamines only help itching or hives. The auto-injector goes intramuscularly into the anterolateral thigh and can be given through clothing. Skin findings like hives can be absent in anaphylaxis, so their absence does not rule it out. The course teaches the auto-injector device sizes, 0.3 mg for adults and 0.15 mg for children, for exam recognition only; weight cutoffs differ by source.

Naloxone reverses opioids, but it is not the first step. The course's order of care for an opioid overdose with respiratory depression is:

1. Support the airway and ventilate with oxygen
2. Give naloxone per protocol
3. Reassess breathing and mental status
4. Transport and watch for re-sedation

An unresponsive 24-year-old breathing 4 times a minute with pinpoint pupils is ventilated first. Normal-size pupils do not rule out opioids. Within EMT scope, naloxone comes as a unit-dose intranasal device or an IM auto-injector; IV naloxone is AEMT and up. The standard nasal spray delivers a single 4 mg dose, again listed for recognition. A patient who wakes up still gets transported, because the opioid may outlast the naloxone. Agitation, nausea and vomiting after naloxone are known effects, so protect the airway.

Albuterol and the asthma traps

Albuterol is a beta-2 agonist that relaxes bronchial smooth muscle. The indication is bronchospasm with wheezing, and the expected effect is bronchodilation with less work of breathing. Nebulized treatments run on oxygen at 6 liters per minute, and the course lists a 2.5 mg nebulized dose as usually enough for mild wheezing without distress, with local protocol and medical direction setting the actual dose. Ipratropium, an anticholinergic, appears in the NASEMSO national guidelines as an add-on nebulized with albuterol; the course treats it as a concept to recognize, not a core EMT drug.

Two distractors to expect: crackles from pulmonary edema are not treated with a bronchodilator, and IV magnesium or epinephrine for severe asthma is ALS-level care, not EMT scope.

What is outside EMT scope

Knowing what you cannot give answers many items by elimination:

• IV and IO routes (AEMT and paramedic). Intramuscular injection was added to EMT scope by a 2021 change notice to the national model, with medical direction expected to confirm experience preparing and drawing up medications, so check what your state allows.
• Glucagon and IV dextrose
• Nitroglycerin from EMS stock (assisting with the patient's own is allowed)
• IV naloxone

If an answer choice needs an IV, it is almost never the EMT answer.

The six rights and contraindications

Before giving any medication, the EMT checks the six rights in the Michigan protocol: right patient, dose, medication, route, time and documentation, including the patient's response. In EMS settings, the most frequent errors are with the medication, the dose and the route. A contraindication is a reason not to give a drug, the opposite of an indication. For children, weight is estimated with a length-based tape, and a child never receives more than the adult maximum dose.

How to study the list

Seven drugs is a small table, but each one has four or five attributes that get mixed up. Study it the way you would any comparison table:

• Fill the table in from memory, then check it. Drug names, classes and indications become fast with a little medical terminology: "broncho-" and "-dilator" tell you what albuterol does, and the word-parts guide covers the rest. How to memorize a list, a table or a formula sheet explains the blank-table method.
• Quiz the contraindications as scenarios. Low blood pressure plus nitroglycerin, can't swallow plus oral glucose. The testing effect is why answering beats rereading.
• Space it. A short list is easy to cram and easy to forget. What spaced repetition actually does explains why short reviews spread over weeks hold up better.

Anaphylaxis and allergic reactions also run through the immunity units of microbiology, which is useful background if you are heading toward paramedic or nursing school. If you have studied pharmacy drug lists before, how to memorize the top 200 drugs uses a similar approach at a much larger scale.

For the exam itself, how the NREMT cognitive exam works explains adaptive scoring, how to study for the NREMT EMT exam builds the full plan, and EMT vs paramedic explains why the paramedic drug list is so much longer. The intro college course flashcards hub lists free courses for related subjects.
