10 free AEMT practice questions: Scene Safety, Personal Protection, and Infection Control

These are real questions from the same bank the app draws from. Each one is written to the NREMT AEMT content specifications and kept inside the AEMT scope of practice. Pick an answer and you get the full rationale, including why the other three options are wrong.

Work through all 10, then move on to the next topic. When you want the full picture, the free AEMT diagnostic covers every topic in one sitting. No account needed for any of it.

Question 1 of 10

An AEMT arrives at a suburban backyard for a 6-year-old patient with a dog bite to the forearm. The patient is standing with a parent near the back porch. The dog that bit the patient is loose in the yard and is barking at the crew from a few feet inside the gate. What should the AEMT do first?

Show the answer and rationale

Correct answer · Ask the parent to confine the dog before entering

An animal that has already bitten one person is an active scene hazard, and hazards are controlled before patient contact rather than worked around. The fastest safe control is to have the owner or a family member confine the animal in the house or a kennel; if no one can do that, animal control or law enforcement is requested and the crew waits. Entering the enclosure with the animal loose risks a second bite that would leave the crew unable to care for the original patient. The patient is stable and standing, so nothing is lost by taking the seconds needed to secure the dog.

Why the others are wrong

Enter the yard and walk around behind the dog: Entering and walking around behind the dog still puts the crew within reach of an animal that's already shown aggression by barking, without the animal being controlled first.

Enter the yard while a partner distracts the dog: Entering while a partner distracts the dog still exposes both providers to a loose, agitated animal rather than removing the hazard before entry.

Enter the yard holding a blanket to shield the crew: Entering with a blanket as a shield doesn't reliably control a loose dog and still risks a bite during the approach.

Question 2 of 10

An AEMT crew arrives at a two-vehicle collision on a two-lane road at 1500. Traffic is still moving past the scene in both directions. Three uninjured occupants are standing in the travel lane beside the damaged vehicles, and a 41-year-old patient with a painful, swollen lower leg is seated in a car on the shoulder. What should the AEMT do first?

Show the answer and rationale

Correct answer · Direct the uninjured occupants off the roadway

The scene size-up obligation covers everyone present, not only the identified patient: the AEMT protects self, other responders, the patient, and bystanders from existing and potential hazards. Uninjured occupants standing in a live travel lane are in immediate danger of being struck, which is a greater and more time-critical threat than an isolated lower-leg injury in a patient who is already off the roadway. Moving them behind a guardrail or well off the shoulder removes the hazard in seconds and also prevents the crew from having to work around people in the lane. Patient assessment resumes immediately afterward, with nothing lost.

Why the others are wrong

Begin the assessment of the patient with the leg injury: Beginning the assessment of the patient with the leg injury before addressing the crowd in the travel lane leaves untrained bystanders standing in immediate danger of being struck while care continues nearby.

Ask the uninjured occupants to help move the patient: Asking the uninjured occupants to help move the patient puts them to work instead of removing them from the hazard they're currently standing in, moving them off the roadway is the priority, not assigning them a task.

Have the uninjured occupants wait inside their vehicles: Having the uninjured occupants wait inside their vehicles doesn't address that they're currently standing in a live travel lane right now. They need to be moved off the roadway immediately, not just told to go somewhere.

Question 3 of 10

An AEMT is triaging patients on the platform of a transit station after an explosion. Law enforcement and fire units are on scene, and several patients have been gathered against the far wall. A station employee points out an unattended backpack lying about 15 feet from the group of triaged patients. What should the AEMT do?

Show the answer and rationale

Correct answer · Move the patients and crew away and notify law enforcement

An explosion of unknown cause is treated as a potential intentional event, and an unattended container near the casualty collection point is treated as a possible secondary device aimed at responders. The response is to increase distance and report, not to investigate: the patients and crew are moved away and law enforcement, who own the assessment and disposal of suspicious items, are notified immediately. Triage is important, but no triage tag protects anyone from a device that functions in the middle of the group. Handling, opening, or guarding the object all keep people in the blast area and add the AEMT to the casualty list.

Why the others are wrong

Open the backpack to determine whether it is a hazard: Opening the backpack risks triggering a device if it is one, handling or investigating a suspicious item is never the AEMT's role.

Carry the backpack to an empty area at the end of the platform: Carrying the backpack to another area is especially dangerous, moving a suspicious item can trigger it and adds the AEMT to the casualty list.

Continue triage and post a crew member near the backpack: Continuing triage with a crew member merely posted nearby still keeps people within the blast radius of a possible secondary device.

Question 4 of 10

While controlling bleeding in the back of the ambulance, blood splashes onto an AEMT's forearm above the glove. The skin is intact. After patient care is transferred at the hospital, what should the AEMT do first?

Show the answer and rationale

Correct answer · Wash the area with soap and water

The first action after blood contacts skin is to wash the exposed area with soap and water as soon as patient care allows. Washing physically removes the organisms rather than relying on a chemical to inactivate them, and it does so without injuring the skin. Reporting the exposure to the designated officer follows, because that starts the evaluation and any follow-up testing, but it does not replace immediate washing. Caustic agents are never applied to skin as a substitute for washing.

Why the others are wrong

Apply an alcohol-based hand rub to the area: An alcohol-based hand rub doesn't remove visible organic material like blood. It's meant for hands that aren't visibly soiled, not this situation.

Cover the area and report it at the end of the shift: Covering the area and reporting it at the end of the shift delays decontamination that should happen as soon as patient care allows, not hours later.

Scrub the area with a dilute bleach solution: Scrubbing with a dilute bleach solution isn't appropriate for skin: soap and water is the correct method for washing exposed, visibly soiled skin.

Question 5 of 10

An AEMT responds to a warehouse where a worker was exposed to a dry chemical. The hazardous materials team has completed decontamination and has moved the patient to the cold zone. The patient is alert, has no remaining product on the skin or clothing, and reports skin irritation. Which protective equipment should the AEMT wear to treat this patient?

Show the answer and rationale

Correct answer · Examination gloves and eye protection

Protective equipment is chosen for the hazard that is actually present, and after decontamination the chemical hazard has been removed with the product. In the cold zone the remaining risks are the ordinary ones of patient care: body fluids and splash, so standard precautions are what the AEMT needs. Continuing to work in chemical protective gear delays assessment, limits dexterity and hearing, and adds heat stress without reducing any remaining risk. The corresponding rule runs the other way as well: before decontamination, a patient is not treated by an AEMT in examination gloves.

Why the others are wrong

Chemical-resistant suit and respirator: A chemical-resistant suit and respirator are needed before decontamination, not after. This patient has already been decontaminated and the chemical hazard has been removed.

Self-contained breathing apparatus: addresses an active chemical or respiratory hazard, which isn't present once decontamination is complete.

N95 respirator and gown: An N95 respirator and gown address an infectious or airborne hazard, not the residual splash/body-fluid risk this cold-zone patient actually presents.

Question 6 of 10

An AEMT is caring for a patient who is still seated in a vehicle after a collision on a rural highway. The rescue crew is about to remove the windshield and cut the roof posts, and the AEMT will stay with the patient during the cutting. Which additional protective equipment should the AEMT put on?

Show the answer and rationale

Correct answer · Helmet and eye protection

The hazard in the passenger compartment has changed from a biological one to a mechanical one. Cutting glass and metal throws fragments and creates a struck-by risk from tools and from the roof as it is moved, so head and eye protection are what the task calls for on top of the gloves already worn. Protective equipment is selected from the hazards present at that moment, not from a fixed patient-care set. Respiratory and gown protection address fluid and airborne exposure, neither of which is what cutting produces.

Why the others are wrong

Gown and examination gloves: A gown and examination gloves address fluid exposure, but they don't protect against the fragments and struck-by hazards created by cutting glass and metal.

Surgical mask and eye protection: A surgical mask and eye protection provide some splash protection but don't address the head-strike risk from cutting tools and a moving roof structure.

Respirator and examination gloves: A respirator and examination gloves address airborne or respiratory hazards, not the mechanical cutting hazard actually present during this extrication.

Question 7 of 10

An AEMT responds at 0500 to a third-floor apartment for a 70-year-old patient who called for help and then stopped speaking on the phone. The apartment door is locked, no one answers repeated knocking, and a television can be heard inside. The building manager cannot be reached. Which resource should the AEMT request?

Show the answer and rationale

Correct answer · The fire department for forcible entry

A caller who goes silent behind a locked door is a patient the AEMT has not reached, and reaching that patient is an access problem, not a treatment problem. Forcing a door is a rescue task with its own tools, training, and liability, and the fire department carries all three, so that is the resource the size-up should generate. Requesting it immediately rather than working through slower options is what keeps the delay short. Access resources are requested on the same trigger as any other resource: the scene needs something the crew cannot safely provide.

Why the others are wrong

An additional ambulance crew for lifting: doesn't solve the actual problem, which is a locked door blocking access to a patient who may need help right now.

The building's on-call maintenance service: Building maintenance may be able to unlock a door eventually, but they don't carry the tools or training for forcible entry the way the fire department does, and time matters here.

A supervisor to authorize entry: A supervisor authorizing entry doesn't provide the forcible-entry capability itself. That's a fire department task, not an administrative approval.

Question 8 of 10

An AEMT is staged upwind at a chlorine release in the pool chemical room of a community recreation center. A hazardous materials team has set up a decontamination corridor at the edge of the hot zone. Six people walk out of the building toward the ambulance, coughing and rubbing their eyes. What should the AEMT do?

Show the answer and rationale

Correct answer · Direct the six people to the decontamination corridor

Patients who walk out of a release area carry the chemical on their clothing, skin, and hair, so every person who touches them becomes a patient and every space they enter becomes contaminated. Triage, treatment, and transport all happen after decontamination for that reason, and the corridor is already built and staffed. Sending an unsorted group through it costs nothing, because ambulatory patients who walked out are the ones the sort would have deprioritized anyway. Contaminating the ambulance takes the crew, the vehicle, and eventually the receiving hospital out of service for everyone else at the scene.

Why the others are wrong

Triage the six people where they are standing: Triaging the six people where they're standing skips decontamination first, when patients who've walked out are carrying the chemical on their skin, clothing, and hair.

Give oxygen to the people who are coughing: Giving oxygen to the coughing patients before decontamination still leaves the chemical contamination on their bodies, which can spread to the AEMT and equipment.

Load the two worst affected people for transport: Loading the two worst-affected people for transport without decontamination first would take the ambulance and crew out of service for everyone else and spreads contamination into the vehicle.

Question 9 of 10

An AEMT sustains a needlestick injury from a contaminated needle left on a stretcher during patient transport. The source patient's bloodborne pathogen status is unknown. After stopping transport briefly, what is the AEMT's immediate priority?

Show the answer and rationale

Correct answer · Wash the wound with soap and water, and notify the receiving facility and EMS medical director

Post-exposure to bloodborne pathogens requires immediate wound care: washing the wound with soap and running water, which mechanically flushes contamination out of the puncture. Squeezing or otherwise encouraging the wound to bleed further is not recommended: it traumatizes the tissue without reducing infection risk. The AEMT must also immediately notify both the receiving facility and the EMS medical director to start exposure-control protocols, documentation, and evaluation for post-exposure prophylaxis if indicated. Time is the reason both halves are urgent: prophylaxis eligibility is measured in hours, so the notification is as time-critical as the wound care.

Why the others are wrong

Apply direct pressure to the wound and resume transport to complete patient delivery: Direct pressure is the correct reflex for bleeding you are trying to stop, and the patient in the back does still need to be delivered, but resuming transport without washing the wound or notifying anyone spends the part of the exposure window that matters, since prophylaxis decisions are made in hours, not at shift change.

Apply a sterile bandage and postpone notification until the end of the shift: A sterile bandage is appropriate wound care for a clean minor injury with no exposure risk, such as a scrape on a cabinet edge. This was a contaminated needle from a source whose bloodborne pathogen status is unknown, which is the exact situation the exposure-control plan exists for. The bandage is not really the error; the delay is, because postponing notification can push the AEMT past the window where prophylaxis still works.

Rinse with alcohol-based hand sanitizer and document the incident in the PCR: Alcohol-based hand sanitizer is the correct product for routine hand hygiene between patients when hands are not visibly soiled. It cannot help a puncture, because the contamination has been injected beneath the skin and a surface product cannot reach it. Documenting in the patient care report is also the wrong record: an occupational exposure gets its own exposure report and notification chain, and that chain is what actually triggers the prophylaxis evaluation.

Question 10 of 10

During scene size-up at a residential call, an AEMT learns from a family member that the patient has a documented severe latex allergy. The AEMT is equipped with both latex and non-latex (nitrile) gloves in the aid bag. Which personal protective equipment modification should the AEMT implement for this patient encounter?

Show the answer and rationale

Correct answer · Use non-latex nitrile gloves to protect the patient from triggering an allergic reaction

Patient-specific allergies must be recognized during scene assessment and incorporated into PPE selection. A patient with documented latex allergy requires latex-free gloves; non-latex nitrile gloves are the appropriate choice. Standard precautions protect both AEMT and patient.

Why the others are wrong

Use latex gloves because they provide superior fit, tactile sensitivity, and barrier protection: Incorrect. Latex gloves contraindicate a known latex allergy regardless of their protective qualities. B is the patient-safe choice.

Avoid wearing gloves altogether to completely eliminate any latex contact risk: Incorrect. Gloves are essential for standard precautions and patient protection; the solution is latex-free gloves, not no gloves.

Use latex gloves initially; if the patient shows signs of allergic reaction, switch to non-latex gloves: Incorrect. Waiting for an allergic reaction exposes the patient to an unnecessary, potentially serious medical event; the allergy must be recognized during scene size-up and non-latex gloves selected proactively before patient contact.
