10 free Paramedic 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 Paramedic content specifications and kept inside the Paramedic 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 Paramedic diagnostic covers every topic in one sitting. No account needed for any of it.

Question 1 of 10

A paramedic responds to a residence at 1830 for a 4-year-old patient bitten by the family dog. A parent meets the crew at the front door and states the dog is still loose inside the house. What should the paramedic do?

Show the answer and rationale

Correct answer · Wait outside until the dog is secured in a separate room

An animal that has already bitten someone in the household is a known, active hazard, and a dog that is loose can move faster than any crew carrying equipment. The scene is not safe to enter until the animal is physically confined behind a closed door or removed from the residence, and the occupant is the person who can do that fastest. Waiting at the door costs seconds and prevents a crew injury that would leave the child with no one to treat them. Scene safety is reassessed continuously, so the same rule applies again if the animal is released later in the call.

Why the others are wrong

Enter the residence and ask the parent to hold the dog: Entering and asking the parent to hold the dog still puts the crew inside the same space as an animal that has already bitten someone, with no barrier while the request is being carried out.

Enter the residence with the stretcher between the crew and the dog: Entering with the stretcher between the crew and the dog doesn't reliably control a loose animal that can move faster than a crew carrying equipment.

Enter the residence after confirming the dog is vaccinated: Entering after confirming vaccination status addresses a different concern: rabies risk, but doesn't address the immediate physical hazard of a loose, agitated dog.

Question 2 of 10

A paramedic wearing a gown, an N95 respirator, and eye protection approaches a 4-year-old patient at a residence for a fever and a forceful cough. The child screams and pulls away when the paramedic comes close. A parent asks the paramedic to take the mask off. What should the paramedic do?

Show the answer and rationale

Correct answer · Keep the equipment on and explain it simply

Indicated protective equipment is not negotiable, because taking it off does not make the child less infectious. It only exposes the paramedic, the partner, and every patient the crew touches for the rest of the shift. Preschool children are frightened by covered faces as a developmental norm, so the answer is to keep the equipment on and manage the fear: crouch to the child's level, speak in a calm and unhurried voice, name what the equipment is in words a 4-year-old follows, let the child see it up close or on the parent first, and keep the parent within sight and touch throughout. Explaining the reason to the parent in the same breath usually converts the request into cooperation. Forcing the assessment is the opposite move, since restraint escalates the fear the paramedic is trying to defuse and makes every later finding harder to obtain.

Why the others are wrong

Remove the respirator while near the child: Removing the respirator while near the child takes off indicated protective equipment, doing so doesn't make the child less infectious, it just exposes the paramedic, the partner, and every patient touched for the rest of the shift.

Ask the parent to hold the child down for the assessment: Asking the parent to hold the child down for the assessment escalates the fear the paramedic is trying to defuse and makes every subsequent finding harder to obtain accurately.

Remove the eye protection and keep the respirator: Removing the eye protection and keeping the respirator still takes off part of the indicated protective equipment for no clinical reason: the fix here is managing the child's fear, not removing gear.

Question 3 of 10

A paramedic arrives at a farm where a worker has collapsed inside a grain bin and is lying motionless in the grain about 8 feet below the access hatch. Three coworkers are tying a rope around one of themselves and preparing to climb in. The confined space rescue team has been dispatched and is 15 minutes away. What should the paramedic do?

Show the answer and rationale

Correct answer · Instruct the coworkers to stay out of the bin

A grain bin is a confined space with two hazards a rope does not touch: an atmosphere that may be oxygen deficient or full of toxic gas and dust, and grain that flows like liquid and engulfs anyone standing on it. A worker already motionless in the bin is evidence that the space is doing exactly that. Most confined space deaths are would-be rescuers who entered after the first victim, so the paramedic's immediate task is to keep everyone out until the trained team arrives with atmospheric monitoring, ventilation, and retrieval equipment. The job task extends the paramedic's protective duty to bystanders, which on this scene means preventing three additional patients rather than reaching the one already down.

Why the others are wrong

Direct the coworkers to enter with the rope in place: Directing the coworkers to enter with a rope doesn't address the atmospheric hazard or the engulfment risk from flowing grain: a rope alone doesn't protect against either.

Send one coworker in to open the bin's lower hatch: Sending one coworker in to open a lower hatch still puts an untrained person into the same hazardous atmosphere and engulfment risk that likely caused the first collapse.

Have the coworkers enter in pairs to remove the patient: Having coworkers enter in pairs multiplies the number of people exposed to the same hazards rather than reducing the risk.

Question 4 of 10

A paramedic 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 paramedic 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 paramedic 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 a paramedic 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 5 of 10

During scene size-up, what makes an incident a mass-casualty incident?

Show the answer and rationale

Correct answer · The number of patients is greater than the resources available to care for them

An incident becomes a mass-casualty incident when the demand outruns what you have to meet it. Two patients with one crew and backup twenty minutes out is an MCI. Ten patients with ten ambulances already on scene is not. That is why no patient number appears in the definition, and why the same crash can be an MCI in a rural district and a routine call across town.

Why the others are wrong

Three or more patients are involved: Some services use a number like this as the trigger for a specific response plan, but a trigger is not a definition. What decides it is whether you are overwhelmed, not the headcount.

At least one patient is in critical condition: One critical patient with a full crew and a close hospital is an ordinary call. Severity by itself does not create an MCI.

More than one agency is dispatched: Mutual aid gets called for single-patient extrications all the time. That reflects the kind of call, not whether resources are outrun.

Question 6 of 10

A paramedic is preparing to transport a 62-year-old patient from a homeless shelter who reports three weeks of coughing, night sweats, and unintended weight loss. The patient is alert and speaks in short phrases, and the breathing is labored. The vital signs are BP 132/84, P 110, R 26, and SpO₂ 86% on room air. The paramedic and the partner are already wearing gloves, goggles, and fitted N95 respirators. What is the most appropriate action for the paramedic to take?

Show the answer and rationale

Correct answer · Place an NRB on the patient at 15 L/min

A patient suspected of having an airborne- or droplet-spread disease is masked for source control, but once that patient needs oxygen the source directs that the surgical mask be replaced rather than kept in place. A saturation of 86% on room air with labored breathing is that oxygen need, and the standard precautions guidance is to substitute an NRB for the surgical mask and set the flow at 10 to 15 L/min. The NRB still covers the mouth and nose, and the crew's own protection comes from the fitted respirators, goggles, and gloves already in place.

Why the others are wrong

Place a surgical mask on the patient over a nasal cannula: Students who want to preserve source control layer a low-flow device underneath the surgical mask. A nasal cannula cannot correct a saturation of 86% with labored breathing, and the NRB replaces the surgical mask rather than being added under it.

Place a particulate respirator on the patient over a nasal cannula: This is the belief that the mask with the best filtration must be the best choice for everyone on scene. A particulate respirator belongs on the provider; on the patient it is uncomfortable, adds nothing, and still leaves the oxygen need unmet.

Place a surgical mask on the patient and continue to monitor: This applies the general rule for a coughing patient and stops there. The question gives a saturation of 86% on room air with labored breathing, so monitoring alone leaves a treatable hypoxia untreated.

Question 7 of 10

A crew has transferred a patient with a large scalp laceration at the emergency department. Blood is on the squad bench and on the stretcher rails. The paramedic has removed and discarded the gloves worn during patient care, has washed the hands, and is now preparing to clean and disinfect the patient compartment. Which gloves should the paramedic put on for this task?

Show the answer and rationale

Correct answer · Heavy-duty utility gloves

Cleaning and disinfecting the unit is a different task from patient care and takes a different glove. Heavy-duty utility gloves are what the source specifies for cleaning and disinfecting the ambulance, and it rules out lightweight latex and vinyl gloves for cleaning by name. Examination gloves are described as the choice for patient contact and procedures, not for cleaning work.

Why the others are wrong

Two pairs of latex examination gloves: Double gloving is a real recommendation, but it belongs to patient care where there is substantial bleeding. The patient has already been transferred, and stacking two lightweight latex gloves does not make either one a cleaning glove.

A fresh pair of vinyl examination gloves: This treats any clean barrier as adequate for any task. Lightweight vinyl examination gloves are named among the gloves that are not used for cleaning.

Leather rescue gloves over examination gloves: Leather rescue gloves are selected for puncture protection during extrication, not for handling disinfectants. Leather itself has to be treated as contaminated material until it can be properly decontaminated, so it adds a problem rather than solving one.

Question 8 of 10

A paramedic is returning an ambulance to service after transporting a patient with a bleeding head wound. A patch of dried blood remains on the squad bench. The used linen has been stripped from the stretcher and the contaminated disposable supplies have been discarded. The paramedic is holding a spray bottle of hospital-approved disinfectant. What should the paramedic do next?

Show the answer and rationale

Correct answer · Wash the bench with soap and water, then apply the disinfectant

Cleaning and disinfection are two different steps in a fixed order. Cleaning is the removal of the visible contaminant, and for a contaminated area on the unit that means washing it with soap and water; disinfection is the killing of pathogens by applying a chemical made for that purpose. For disinfection to be effective, the cleaning has to be done first. Spraying a disinfectant onto dried blood leaves the blood in place and leaves the chemical unable to reach what is underneath it.

Why the others are wrong

Spray the disinfectant on the blood and wipe the bench dry: This gets the sequence wrong and then compounds it. Bleach solutions and most disinfectants have to stay wet on the surface for a stated contact time, so wiping the bench dry cuts the disinfectant's working time short.

Spray the disinfectant on the blood and let the bench air dry: This is the strongest wrong answer, because the air-drying half of it is correct. It still skips the wash, and dried blood on the surface is exactly what keeps the disinfectant from reaching the pathogens beneath it.

Spray the disinfectant on the blood and repeat at the station: Repeating an application does not stand in for the step that was skipped. The blood is still on the bench for both applications, and the unit carries it back to the station either way.

Question 9 of 10

A 72-year-old patient in a skilled nursing facility has acute abdominal pain. The patient is continent, has no visible bleeding, and reports nausea. Several other patients in the facility are quarantined in a separate wing because of a gastroenteritis outbreak. Which precautions should the paramedic apply for this patient contact?

Show the answer and rationale

Correct answer · Gloves and a gown, for possible exposure to gastrointestinal fluid

Personal protective equipment (PPE) selection incorporates facility context (active outbreak) and patient symptoms (nausea, abdominal pain, possible vomiting). Gastroenteritis is transmitted primarily through contact with vomitus or stool (the fecal-oral / contact route), not by respiratory droplets. Standard precautions (gloves) plus contact precautions (gown) address the risk of exposure to gastrointestinal fluids from a patient with nausea and abdominal pain during an active outbreak. Respiratory precautions (mask) and eye protection are not the primary need here, because gastroenteritis does not spread by the respiratory route.

Why the others are wrong

Gloves only, because there is no visible bleeding: Incorrect. While there is no active bleeding, the facility's active gastroenteritis outbreak and the patient's nausea and abdominal pain raise the risk of exposure to vomitus or stool. Contact precautions (gown) are indicated in addition to gloves.

Gloves and a mask, given the gastroenteritis outbreak: Incorrect. Gastroenteritis spreads by the fecal-oral/contact route, not primarily by respiratory droplets. A mask does not address the actual exposure risk; a gown for possible contact with GI fluids is the appropriate addition to gloves.

Gloves, mask, gown, and eye protection, as for active infection: Incorrect. Full PPE including mask and eye protection is not indicated for a GI illness without evidence of respiratory symptoms or active fluid splash; gloves and a gown are sufficient for the anticipated exposure.

Question 10 of 10

A paramedic responds to a single-vehicle rollover on a rural highway. The vehicle has rolled about three times and is on its side. One occupant is alert, asking for help, and reporting arm pain. The vehicle is stable and no hazards are apparent. Which resource request is most appropriate?

Show the answer and rationale

Correct answer · Police for traffic control and fire for extrication standby

Resource requests are driven by the number of patients and their anticipated needs, not by mechanism of injury alone. A rollover is a high-energy mechanism that can hide occult injury, so police (traffic control on a highway) and fire (extrication standby, in case the patient becomes trapped or the vehicle shifts) are reasonable precautions. There is only one patient, and the ambulance already on scene can transport that patient once care is complete. Requesting a second ambulance is unnecessary until a second patient is found.

Why the others are wrong

Police, fire for extrication standby, and one more ambulance: Incorrect. Only one patient has been identified. The ambulance already on scene can transport that patient; a second ambulance is not needed unless another patient is found.

No additional resources; transport the patient immediately: Incorrect. Skipping police and fire ignores the need for traffic control on a busy highway and standby extrication capability for a high-energy rollover, even though the patient initially appears stable.

Police only; extrication is unlikely given the alert patient: Incorrect. A three-time rollover carries meaningful potential for the patient to become trapped or for the vehicle to shift; fire should be requested for extrication standby even though the patient is currently alert and communicating.
