10 free Paramedic practice questions: Ambulance Operations and Equipment Readiness
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 is checking the airway equipment carried on the ambulance at 1900. The battery-powered portable suction unit runs and holds a charge. Which additional device allows suctioning to continue if that unit loses power during a call?
Show the answer and rationale
Correct answer · A manually operated suction device
A manually operated suction device is your backup. A manual unit runs on hand power and needs no battery or vehicle power. Suction is one of the few treatments with no workaround when the equipment quits. That's why ambulances carry a hand-powered unit. Check that the backup is there and working during the same check that covers the powered unit. Only the manual unit makes its own vacuum. Tips, catheters, canisters, and tubing only carry or direct the vacuum.
Why the others are wrong
A rigid pharyngeal suction tip: the delivery end of the suction system. The tip makes no vacuum on its own, so it does nothing once the power is gone.
A large-bore suction catheter: another delivery part. The catheter only works with a powered or manual unit pulling vacuum behind it.
A spare collection canister and tubing: A spare canister and tubing replace the parts that collect and carry what you suction. Neither part makes suction if the powered unit fails.
Question 2 of 10
A paramedic is placing a portable oxygen cylinder in service at 0715. When the cylinder valve is opened, a loud hiss comes from the connection between the regulator and the cylinder valve, and the gauge pressure begins to fall. What should the paramedic do?
Show the answer and rationale
Correct answer · Close the valve and replace the sealing gasket
Close the valve and replace the sealing gasket. The hiss is coming from where the regulator meets the cylinder valve, and the gauge pressure is falling. A leak at that spot means the seal at the yoke is not intact. That seal is made by a small gasket. Gaskets flatten, tear, or fall out with repeated cylinder changes. Close the valve and bleed off the pressure. Fit an intact gasket and hand-tighten the yoke. Open the valve again and confirm the leak is gone.
Why the others are wrong
Tighten the yoke screw with an adjustable wrench: Tightening the yoke screw with a wrench tries to force a seal the gasket is supposed to make. With a bad or missing gasket, extra tightening does not fix the seal. The yoke only needs to be hand-tightened once a good gasket is in place.
Apply a thin film of lubricant to the fitting: Lubricant at an oxygen fitting is a fire hazard. Oxygen supports combustion, and any petroleum product at a pressurized oxygen fitting can ignite. Lubricant does nothing to fix the leak either.
Wrap the connection with waterproof tape: Waterproof tape over the connection does not rebuild the seal at the valve outlet. The tape also adds another fire risk at a fitting carrying oxygen under high pressure.
Question 3 of 10
During the morning equipment check, a paramedic verifies that the portable glucometer's test strips expired two months ago. The container was opened at the time of expiration and has been stored in the ambulance. The paramedic may need to assess blood glucose on several patients during the shift. What is the most appropriate action?
Show the answer and rationale
Correct answer · Remove the expired test strips from service and replace them with a new, unexpired container
The strips expired two months ago, and the container has been open since that date. The expiration date is the last date the manufacturer guarantees an accurate reading. Past that date, with the container open the whole time, you cannot trust a reading from these strips. A reading can look normal on a patient whose blood sugar is really low. If you believe that number, you miss the hypoglycemia and delay treatment. You may need several glucose checks this shift. Pull these strips from service and stock a new, unexpired container before the shift starts.
Why the others are wrong
Use the expired strips because they are stored in a sealed container: A sealed container helps protect strips that are still in date. Sealing does not change the expiration date. This container has also been open for two months.
Try the expired strips; if the result is abnormal, recheck per medical control guidance: Rechecking an abnormal result per medical control makes sense when the strips are good. These strips can give a normal number on a hypoglycemic patient. A normal number never sets off the recheck, so that patient gets missed. Trying the strips also keeps expired equipment in service.
Use the expired strips only for screening; if they show normal glucose, proceed without further assessment: Screening with a quick glucose check works when you can trust the strips. A normal reading from these strips can be wrong. Proceeding without further assessment means nobody checks that glucose again, and a low blood sugar gets missed.
Question 4 of 10
A paramedic is completing the daily check of the automated external defibrillator at 0645. The defibrillator powers on and completes its self-test without an error. The battery installed in the unit is fully charged and its printed expiration date is 8 months away. Two sets of electrodes are sealed in their packages with valid dates, and the charger is plugged in and operating. The spare battery in the carry case is fully charged, but the expiration date printed on it passed 3 weeks ago. Which action is most appropriate?
Show the answer and rationale
Correct answer · Exchange the spare battery for one that is within its date
The spare battery is expired, so this defibrillator fails its check. The expiration date printed on the spare passed 3 weeks ago. Every other part of the check passes. The self-test only tells you the unit and the installed battery work right now. The charger and the charge level tell you the batteries hold energy. None of those checks reads a printed expiration date. The defibrillator check requires a valid date on both batteries, not only on the one in the unit. The spare is there to go in when the first battery fails. An expired spare leaves the unit with no dependable second battery. A battery that does not work is a known cause of a defibrillator failing to deliver a shock. Exchange the spare before the unit goes in service.
Why the others are wrong
Install the spare in the unit and charge the battery removed: Rotating batteries on a schedule is a real practice. Rotation moves current batteries into service, not expired ones. The installed battery is fully charged and has 8 months left. Swapping them takes a good battery out of the unit and puts the expired one in.
Record the date on the check sheet and repeat the self-test: Repeating the self-test makes sense when the self-test showed an error. This self-test already ran without an error. The self-test only checks the battery installed in the unit. The self-test cannot read the date printed on a spare in the carry case, so running it again gives you the same result.
Keep the spare and recheck its charge at the next shift check: Rechecking the charge would matter if the problem were a low charge. The spare is already fully charged, and the problem is the expired date. Holding a charge for another shift does not make an expired battery current.
Question 5 of 10
During the shift equipment check, a paramedic tests the portable suction unit. The unit was left on its charger overnight and the battery indicator reads full. With the unit running and the tubing clamped, the vacuum gauge rises to 180 mm Hg and stops. The collection canister is empty, and the tubing is wide-bore and free of cracks or kinks. Which action is most appropriate?
Show the answer and rationale
Correct answer · Recheck the assembly of all its parts, then retest
This suction unit fails its vacuum test, and the most likely cause is a leak in the assembly. A suction unit has to reach more than 300 mm Hg with the tubing clamped. This unit stops at 180 mm Hg. The power is fine, because the unit charged overnight, the battery indicator reads full, and the motor runs. The test was done the standard way, with the tubing clamped. The tubing is wide-bore with no cracks or kinks. What is left is the assembly. The unit only builds vacuum when every joint seals, from the canister and its lid to the yoke and the tubing. Check that every part is put together correctly, then retest.
Why the others are wrong
Replace the battery, then repeat the vacuum test: A new battery is the fix when the unit is not getting enough power. This unit charged overnight, the indicator reads full, and the motor runs. A unit with a running motor is getting power. A weak battery does not explain a gauge that climbs to 180 mm Hg and stops.
Read the gauge again with the tubing unclamped: Unclamping would make sense if the clamp were holding the reading down. The test is written the other way. You test the unit with the tubing clamped, because an open line cannot build vacuum at all. Unclamping only gives you a lower reading.
Attach a rigid tonsil-tip catheter and retest: A rigid tonsil tip is the catheter you would actually use on a patient. Adding the tip narrows the path, so the reading drops even more. The test is already being run the standard way, with the unit running and the tubing clamped.
Question 6 of 10
During the shift check, a paramedic finds the adult traction splint missing from the ambulance. The station storeroom holds a traction splint of a different model that came from a decommissioned unit. No one on the crew has been instructed in its use, and the service's medical director has not approved that model. The unit is otherwise complete and is due to go in service in 20 minutes. Which action is most appropriate?
Show the answer and rationale
Correct answer · Document the missing splint and request an approved replacement
The storeroom splint is not cleared to go on this ambulance. Equipment that goes on an ambulance has to meet two conditions. The crew has to be instructed in the device's use and care. The medical director has to approve the device. The storeroom splint fails both. No one on the crew has been instructed in its use, and the medical director has not approved that model. That's why every option that puts the storeroom splint on the unit is wrong, even with crew practice added. Practice does not give you the medical director's approval. A unit without a traction splint does have a real gap. Write the missing splint on the shift checklist and request an approved replacement through your service. That way the gap gets filled with equipment the crew is cleared to use.
Why the others are wrong
Place the storeroom splint on the unit and read its instructions en route: Reading the instructions is one way to learn a device. Instruction has to happen before the device goes on the ambulance. Reading directions on the way to the call that needs the splint is the exact situation the requirement is there to prevent.
Place the storeroom splint on the unit after the crew practices with it: Hands on practice covers the instruction condition. The medical director's approval is a separate condition. The question says the medical director has not approved that model, so the splint still cannot be carried.
Place the storeroom splint on the unit until the missing one is returned: A temporary substitute sounds acceptable until the real splint comes back. Nothing in the standard depends on how long the device stays on the unit. A splint the crew has not been instructed in and the medical director has not approved is not made acceptable by calling it temporary.
Question 7 of 10
A paramedic is checking the spare portable oxygen cylinders carried on the ambulance. One aluminum cylinder is labeled for medical oxygen, its plastic valve seal was intact until the paramedic removed it, and the regulator gauge reads 2,000 psi once the regulator is attached. The month and year stamped into the collar show that the cylinder was last tested 6 years ago. Which action is most appropriate?
Show the answer and rationale
Correct answer · Remove it from service and report it for retesting
This cylinder is overdue for its retest. The month and year stamped into the collar show the cylinder was last tested 6 years ago. Aluminum cylinders are generally tested every 5 years, and composite cylinders every 3 years. A cylinder last tested 6 years ago is overdue either way. The medical oxygen label tells you what is inside. The intact plastic valve seal tells you the cylinder has not been opened since it was filled. The gauge reading of 2,000 psi tells you how much oxygen is inside. None of those tells you the cylinder itself is still safe to hold that pressure. Pull the cylinder off the unit and send it back for testing. Write the shortfall on the checklist so you get a replacement before the unit goes in service.
Why the others are wrong
Place it in service, since the gauge reads full: A full gauge is the right check for how much oxygen is in a cylinder. Pressure does not tell you when the cylinder was last tested. A cylinder can read 2,000 psi and still be overdue for the test that shows it is safe to hold that pressure.
Crack the valve to confirm it holds pressure: Cracking the valve clears debris from the opening before you attach the regulator. Holding pressure for a few seconds on the station floor is not the test the collar stamp records.
Keep it as the backup and use the newer one: A backup cylinder still gets used. The backup is the one you reach for with a second patient or a long transport. Making an overdue cylinder the backup does not take it out of use.
Question 8 of 10
An ambulance returns from a refit with its cabinets rearranged, and a paramedic is restowing equipment before the unit goes in service. The portable suction unit, the spare oropharyngeal airways, the blood pressure cuffs, and the bleeding control dressings all have to be put away. The attendant seat is at the head of the primary stretcher. The cabinet at the head of the stretcher and the cabinet beside the stretcher each hold two of the four items. Which arrangement is most appropriate?
Show the answer and rationale
Correct answer · Suction unit and airways at the head; blood pressure and dressings at the side
Equipment is stowed by how urgently and how often you need it. Everything for one critical intervention is kept together in one place, so you are not pulling pieces of it out of several cabinets. Airway, ventilation, and oxygen equipment goes within easy reach of the head of the primary stretcher. The attendant seat is at the head, and that is where you sit and work when you manage an airway. The suction unit and the oropharyngeal airways are both airway equipment, so both go in the head cabinet. Equipment for cardiac care, bleeding control, and blood pressures goes at the side of the stretcher. You do those things from the side of the patient. That puts the blood pressure cuffs and the bleeding control dressings in the side cabinet.
Why the others are wrong
Blood pressure and dressings at the head; suction unit and airways at the side: The head cabinet is the easiest one to reach from the attendant seat. Placement follows where you do each intervention, not which items seem most important. Bleeding control and blood pressures are done from the side of the patient. Putting the cuffs and dressings at the head moves the suction and airways away from the seat where you manage the airway.
Suction unit and dressings at the head; airways and blood pressure cuffs at the side: Splitting the suction unit from the airways breaks up the airway group. Airway equipment is packed together so you are not reaching into two cabinets for one intervention. With this setup, you would get suction from the head and airways from the side.
Airways and blood pressure at the head; suction unit and dressings at the side: Moving the suction unit to the side splits the airway group the same way option B does. Suction is the item you most often need without warning. You would be reaching away from the attendant seat to get suction.
Question 9 of 10
A patient with a suspected spinal injury has been placed on a backboard with a cervical collar and head blocks. What should the paramedic do next before transport?
Show the answer and rationale
Correct answer · Secure the patient to the backboard with at least two straps across the torso and legs
Strap the patient to the backboard before transport. The cervical collar and head blocks hold the head and neck. Nothing is holding the body yet. Full spinal immobilization needs at least two straps, and ideally three, across the chest, pelvis, and legs. Some skill sheets put the body straps on before the head blocks, so strapping does not move the head. Either way, the collar and head blocks are already on here. Securing the torso and legs with straps is the next step before you move.
Why the others are wrong
Remove the cervical collar, since the head blocks now hold the head in position: The cervical collar does come off at some point. The hospital makes that decision after imaging or a formal clearance protocol, not the paramedic in the back of the ambulance. The collar and the head blocks do different jobs. The blocks and tape stop the head from turning and tipping side to side. The collar stops the head from nodding forward and back. Take the collar off and the patient can still nod inside the blocks.
Leave the straps loosely fastened so the patient can reposition if uncomfortable: Comfort is a real concern, because a rigid board is miserable to lie on. Loose straps let the patient move, and movement is what the whole setup is there to prevent. Loose straps also will not hold the patient if the ambulance stops hard or swerves. Fix comfort by padding the space behind the head, the small of the back, and the knees.
Begin transport without straps as long as the patient remains calm and cooperative: A calm patient still moves. The body jerks when the ambulance brakes or hits a pothole, and the head turns toward a sudden noise. Hypoxia, a head injury, pain, or a falling blood sugar can make the patient agitated at any point. The mechanism of injury is why the patient is on the board, and the mechanism has not changed because the patient is cooperative.
Question 10 of 10
A patient meets the local criteria for a ST-elevation myocardial infarction, and a cardiac catheterization center is 10 minutes farther away than the closest hospital. What is the correct transport decision?
Show the answer and rationale
Correct answer · Transport to the cardiac catheterization center, since STEMI requires specialized care
This patient meets the criteria for a STEMI. A STEMI means a coronary artery is suddenly blocked. The heart muscle past the blockage is not getting oxygen, and the damage grows with every minute. The treatment is primary percutaneous coronary intervention (PCI), where the cath lab opens the artery with a balloon. Guidelines call for a door-to-balloon time of 90 minutes or less. Door-to-balloon time is the time from arriving at the hospital until the balloon opens the artery. Only a hospital with a cath lab can open the artery. A hospital without a cath lab would have to stabilize the patient and then transfer them. The second trip uses up the same minutes you are trying to save. Driving 10 extra minutes gets the patient straight to the hospital that can open the artery. Bypass the closest hospital and go to the cath center.
Why the others are wrong
Transport to the closest hospital because minimizing transport time takes priority: Going to the closest hospital is the right call when that hospital can give the same care. The closest hospital here has no cath lab. Saving 10 minutes does not help if the patient still needs a transfer to get the artery opened.
Transport to the closest hospital and request a later transfer if needed: Going to the closest hospital and transferring later only makes sense when no cath center is within reasonable reach. A cath center 10 minutes farther away is within reach. Stopping first at a hospital without a cath lab and transferring later adds delay. This plan only adds a second transport and stretches out the door-to-balloon time.
Ask the patient which hospital they would prefer, and transport there instead: A stable patient's choice of hospital is honored when that hospital can treat the problem. A patient with a STEMI goes where the problem can be fixed. The hospital is chosen by what it can do, and this patient needs a cath lab.
