10 free AEMT practice questions: Suctioning and Airway Clearance

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 opens the airway of a 53-year-old patient who is unresponsive on a bathroom floor and hears coarse gurgling with every breath. An oropharyngeal airway, a BVM on high-concentration oxygen, and a working suction unit are all at the head of the cot. What does the AEMT do first?

Show the answer and rationale

Correct answer · Clear the airway with suction before anything else goes in

Gurgling is the sound of liquid sitting in the airway, and liquid is the one thing suction exists to remove. The order matters more than the individual moves here. Anything you put into that airway, an adjunct or a breath, travels through the fluid on its way down, and a breath delivered through vomit or blood drives it into the lungs. Clear it first, then reassess the sound, then choose your adjunct. Lock the ladder in as position, suction, adjunct, ventilate, oxygenate, because a skipped rung makes every rung above it fail.

Why the others are wrong

Insert the oropharyngeal airway and suction around it: An oropharyngeal airway is the right idea for a patient with no gag reflex, and it does make later suctioning easier by holding the tongue forward. What it does not do is remove what is already in there, so you would be seating a device in a pool of fluid and then bagging through it.

Begin BVM ventilation and watch for chest rise: The patient needs oxygen and the bag is right there, which makes this feel like the fastest help you can give. Positive pressure delivered into a mouth full of fluid pushes that fluid toward the lungs, which is the exact injury you are trying to prevent.

Roll the patient onto the side and reassess the sound: Turning a patient to let fluid drain is a real technique and it helps when the volume outruns your suction. It is slower than the catheter already in your hand, and gravity alone will not clear what has already worked its way to the back of the throat.

Question 2 of 10

An AEMT is about to pass a rigid catheter into the mouth of a 46-year-old patient who is unresponsive with blood pooling in the oropharynx after a dental extraction. The catheter has already been measured. Why is the vacuum left off while the catheter goes in?

Show the answer and rationale

Correct answer · Suctioning on the way in removes oxygen and clears nothing

Think of the vacuum as a budget you spend only where it buys something. On the way in, the tip is traveling through air, so all the suction does is pull oxygen out of an airway that already belongs to a patient who is not breathing well. The material you want is in contact with the tip on the way out, which is why the vacuum goes on as you withdraw, in a circular motion, and stays off on the way in. Same catheter, same setting, different half of the trip.

Why the others are wrong

Suctioning on the way in drives material toward the larynx: Pushing material deeper is a genuine hazard in airway work, and it is exactly what a blind finger sweep does with a solid object. Suction pulls rather than pushes, so a running vacuum on the way in is not what drives fluid toward the cords.

Suctioning on the way in makes the rigid catheter collapse: Collapse under vacuum is a real failure mode, which makes this sound right. It belongs to the soft flexible catheter, not the rigid one, and it is the reason you switch to a rigid tip when material is thick.

Suctioning on the way in makes the measured depth hard to judge: Depth control is worth worrying about, since a tip past the base of the tongue triggers gagging and a vagal response. You control that by measuring against the face beforehand, and the vacuum state does not change how deep the tip sits.

Question 3 of 10

An AEMT is suctioning vomit from the oropharynx of a 10-year-old patient who is unresponsive after a bicycle crash. Ten seconds into the attempt the oropharynx still holds a large volume of vomit. What does the AEMT do?

Show the answer and rationale

Correct answer · Withdraw the catheter, ventilate with oxygen, then suction again

Hitting the time limit with a dirty airway is the normal case, not a failure. The limit is not a promise that the mouth will be clean when it expires, it is a cap on how long you may keep a patient apneic. What you owe the patient at that moment is oxygen, so you pull the catheter, ventilate, and go back in for another pass, cycling as many times as it takes. For this patient the ceiling is 10 seconds because a child gets 10, and the cycle itself is identical at every age.

Why the others are wrong

Continue the pass until the oropharynx is finally clear: Finishing the job in one pass is appealing because an airway half cleared still sounds terrible. Every extra second is apnea in a child who has less reserve than an adult, and that is where the saturation and then the heart rate go.

Withdraw the catheter and insert an oropharyngeal airway: An oral airway does belong in this patient eventually, since the vomiting has already shown the airway is undefended. Placing it now seats a device over fluid you have not removed, and it does nothing about the oxygen you just spent.

Switch to a soft catheter and continue the same attempt: A different catheter is a reasonable thought when material is not moving, and switching tools does solve some suctioning problems. A softer catheter handles thick vomit worse, not better, and continuing the same attempt ignores that the clock has already run out.

Question 4 of 10

A 27-year-old patient is awake and confused after an assault, with a split lip bleeding steadily and blood pooling at the back of the mouth. How far does the AEMT advance the rigid catheter?

Show the answer and rationale

Correct answer · Only as far as the tip can be seen

A patient who is awake still has tone, and tone means a gag reflex that a catheter will find. Touching the back of the airway triggers vomiting, which takes a manageable amount of blood in the mouth and turns it into a mouth full of vomit and blood in a patient who is fighting you. The rule for anyone conscious or semiconscious is simple: advance only into the part of the mouth you can actually see, and take what is visible. Save the full measured depth for a patient who has no gag left to provoke.

Why the others are wrong

To the base of the tongue on every pass: The base of the tongue is the landmark your measurement is built around, so it sounds like the right target. That is the depth you avoid in a patient with tone, because it is precisely where the gag reflex lives.

Until the patient coughs, then no further: Waiting for a cough treats the patient as your depth gauge, and a cough does tell you that you have gone too far. By then the airway has already been stimulated, and the next thing it often does is vomit.

To the full depth measured at the earlobe: The measured depth is correct for an unresponsive patient with no gag reflex, which is most of the suctioning you will do. This patient is awake and talking, so the visualized limit governs instead.

Question 5 of 10

An AEMT is checking the portable suction unit at the start of a shift. The tubing is clamped and the gauge is read. Which reading shows the unit is working?

Show the answer and rationale

Correct answer · At least 300 mmHg of vacuum

A suction unit has two numbers worth knowing, and they measure different things. Clamp the tubing and the gauge should read at least 300 mmHg of vacuum, which is the pull. Unclamp it and the unit should move at least 30 L per minute of free flow, which is the volume. A device can pass one and fail the other, and a unit with good vacuum but poor flow will crawl through a mouth full of vomit. Check it at the start of the shift, because the call where you find out is the call where you needed it.

Why the others are wrong

At least 30 mmHg of vacuum: 30 is a real number in the specification and it is easy to grab, which is exactly why it appears here. It is the free flow figure in liters per minute, not a vacuum pressure, and a unit pulling 30 mmHg would barely move saliva.

At least 120 mmHg of vacuum: 120 mmHg sits comfortably in the range of numbers you read off monitors all shift, so it feels plausible. It has nothing to do with suction, and a unit that stalls there will not clear thick material.

At least 760 mmHg of vacuum: 760 mmHg is a figure worth recognizing, since it is atmospheric pressure at sea level. A portable unit is not built to pull a full vacuum, and the published threshold is 300.

Question 6 of 10

An AEMT is caring for a 23-year-old patient who is 36 weeks pregnant and has been vomiting since a syncopal episode, with secretions now pooling in the oropharynx. A working suction unit and a BVM on high-concentration oxygen are both at hand. What does the AEMT do before the catheter goes in?

Show the answer and rationale

Correct answer · Preoxygenate, since pregnancy shortens the time before desaturation

Pregnancy changes the math on every apneic period you create. The uterus pushes the diaphragm up and cuts functional residual capacity, so the reservoir a patient coasts on while you suction is smaller than it looks for the patient's size. That makes preoxygenation before airway work a requirement rather than a nicety. Notice what does not change: the time limit is still 15 seconds for an adult, and the vacuum setting is still the vacuum setting. Pregnancy adjusts what you do before the pass, not the numbers that govern the pass itself.

Why the others are wrong

Shorten the attempt to 10 seconds to match the reduced reserve: Trimming the clock looks like a direct way to protect a patient with less reserve, and the instinct behind it is sound. The limits are set by age, not by reserve, and cutting your own working time means more passes and more total apnea rather than less.

Turn the vacuum down so less oxygen is pulled from the airway: Lowering the pull sounds gentler, and gentleness is often right in airway work. Vacuum is not the variable at any age, and a weaker pull on pooled vomit just keeps the catheter in longer.

Extend the head further back to open a straighter path: Opening the airway before you work in it is a real step, and head position does matter. Extending further than neutral does not add reserve, and in a pregnant patient the pooled vomit is the problem you have not addressed yet.

Question 7 of 10

An AEMT and a partner have been ventilating a 37-year-old patient who is unresponsive and apneic after being pulled from a backyard pool. The upper abdomen has become visibly rounded and firm, and the patient has just vomited a large volume around the mask. What does the AEMT do first?

Show the answer and rationale

Correct answer · Clear the airway with suction before delivering another breath

Gastric distention is a slow-motion warning and this is the moment it pays off. Air forced into the stomach pushes the diaphragm up, the bag gets stiffer, the provider squeezes harder, and eventually the stomach empties into a mouth that has nothing protecting it. Once vomit is in the airway the sequence resets to the bottom of the ladder: suction first, then the adjunct, then the breath. Fixing your rate and volume is the right correction for the cause, but it comes after the airway is clean, because a corrected breath delivered through vomit aspirates just as well as a bad one.

Why the others are wrong

Insert an oropharyngeal airway to hold the vomit off the tongue: An oral airway belongs in a patient with no gag reflex and it does make repeat suctioning easier. Placing it into a mouth that is currently full seats a device in the fluid, and it moves nothing out.

Resume ventilation with smaller breaths delivered more slowly: Smaller, slower breaths are the correct fix for the distention that caused this, so the reasoning is half right. Delivering any breath through vomit drives it toward the lungs, so the correction waits until the mouth is clear.

Place a supraglottic airway to seal the airway below the vomit: Sealing the airway off from contamination is an appealing idea, and this device does seal the hypopharynx. It never isolates the trachea from the esophagus, so a device dropped into vomit traps the fluid below the cuff where positive pressure pushes it down.

Question 8 of 10

A newborn delivers through thick greenish amniotic fluid and is limp with a weak respiratory effort at 20 seconds of life. What does the AEMT do?

Show the answer and rationale

Correct answer · Warm, dry and stimulate, then ventilate if the effort stays weak

Meconium used to reroute this whole call, and it no longer does. A vigorous newborn born through meconium gets routine care, and a newborn who is not vigorous gets the standard initial steps and then positive pressure ventilation if the effort does not improve. Tracheal suctioning of a meconium stained newborn is not performed regardless of vigor. The reason the guidance changed is worth carrying with you: reaching for a meconium specific maneuver instead of ventilating is the error that killed newborns, because the thing a limp newborn needs is air moving, and every second spent on the maneuver is a second that air is not.

Why the others are wrong

Suction the trachea before any ventilation is attempted: This was taught for years and it still feels like the responsible move when the fluid is that thick. It is no longer performed at any level of vigor, and it delays the ventilation that a limp newborn actually needs.

Clear the mouth and nose with a bulb syringe before drying: Bulb suctioning is the right tool for a newborn and the mouth before the nose is the right order, so this is close to correct practice. Routine suctioning is no longer taught, and it belongs here only if secretions are actually obstructing the airway.

Begin chest compressions and reassess the heart rate at 30 seconds: Compressions feel urgent for a limp newborn, and there is a point in the sequence where they are correct. Compressions follow 30 seconds of effective ventilation with a heart rate still under 60, so ventilation comes first.

Question 9 of 10

An AEMT finds an 88-year-old patient unresponsive in a recliner, breathing 14 times a minute with a coarse snoring sound and no fluid visible in the mouth. A partner reaches for the rigid catheter. What does the AEMT do?

Show the answer and rationale

Correct answer · Reposition the head and lift the jaw, since snoring is the tongue

Airway sounds are a sorting tool, and each one points at a different fix. Snoring is the tongue falling back against the posterior pharynx, so it answers to head position and a jaw lift, then an adjunct. Gurgling is liquid, and liquid answers to suction. A solid object answers to a log roll and removal of what you can see. Matching the sound to the fix keeps you from spending an apneic period suctioning a mouth that has nothing in it, and it keeps you from repositioning a patient who is drowning in their own secretions.

Why the others are wrong

Suction the oropharynx first, since the sound comes from the airway: Suction is the right reflex for a noisy airway often enough that it becomes automatic. The noise here is snoring rather than gurgling and there is no visible fluid, so the catheter has nothing to remove and the pass costs oxygen for nothing.

Advance a rigid catheter to the base of the tongue and suction there: Going to the base of the tongue at least aims at the structure making the noise, which is closer to the mechanism than most wrong answers get. A catheter does not hold a tongue forward, and touching that tissue provokes gagging and a vagal response.

Place the patient on the side and suction any fluid that drains: The lateral position is genuinely protective for a patient who cannot guard the airway, so this is not a bad habit. It does not lift the tongue off the posterior pharynx, and the immediate problem here is obstruction rather than drainage.

Question 10 of 10

An AEMT is about to suction a large volume of thick sputum from the mouth of an 85-year-old patient with chronic obstructive pulmonary disease who is unresponsive with a saturation of 84 percent. The patient is on a nasal cannula at 2 L per minute, and a partner says the oxygen should stay low to protect the drive to breathe. What does the AEMT do?

Show the answer and rationale

Correct answer · Ventilate with high-concentration oxygen, then suction the mouth

Two things that are true at once are pulling in opposite directions. Patients with chronic obstructive pulmonary disease are titrated toward their own baseline, with 88 to 92 percent as the working proxy, and that is a real rule. The other is that there is no clinical situation in which withholding oxygen from a hypoxic patient is the right answer, and the drive theory your partner is quoting is not correct and should not be acted on. Look at the number: 84 percent is below the target band, not near it, so titration says give more rather than less. Then add the suction piece. The pass ahead is an apneic period, so the oxygen goes in before the catheter does, not after.

Why the others are wrong

Suction the mouth first, then leave the cannula where it is set: Getting the sputum out matters and it is why you came to the mouth in the first place, so leading with suction has real appeal. It starts an apneic pass in a patient already at 84 percent, and leaving a cannula at 2 L afterward keeps the hypoxia you just deepened.

Leave the cannula at 2 L, since the saturation is near the target: This is the closest call in the set, because titration toward a band is genuinely correct for these patients. The band is 88 to 92 percent and this patient is at 84, so the rule being invoked actually calls for more oxygen.

Suction in passes of 5 seconds to keep the apneic time short: Shortening the apneic time is thinking about the right hazard, and short passes are good practice. 5 seconds is the infant ceiling rather than the adult one, and trimming the clock does not replace the oxygen that should have gone in first.
