Question 1 of 10
An AEMT is transporting a 31-year-old patient who twisted a knee during a recreational soccer game. The knee is splinted and the patient is alert and comfortable. At the start of transport the vital signs are BP 124/76, P 78, R 16, and SpO₂ 99% on room air. Ten minutes later the vital signs are BP 122/78, P 76, R 16, and SpO₂ 99% on room air, and the patient reports no new complaint. The hospital is 35 minutes away. How often should the AEMT repeat the full reassessment for the rest of this transport?
Show the answer and rationale
Correct answer · At least every 15 minutes, or sooner if the condition changes
Two sets of numbers that match, with no new complaint, is a stable patient, and a stable patient gets a full reassessment at least every 15 minutes. The word to hold onto is at least. Fifteen minutes is the floor, not the plan, and anything the patient says or does in between moves the clock up. Notice that you needed both sets to say stable at all. The first set alone only told you where the patient was standing, not which way they were walking.
Why the others are wrong
Every 5 minutes, because a transported patient counts as unstable: Five minutes is the unstable interval, and nothing here is unstable. A normal pulse, a normal pressure, a normal saturation and an isolated splinted knee do not buy this patient the every 5 minute schedule. Riding in an ambulance is not a vital sign.
Once more just before arrival, since two matching sets settle it: Two matching sets tell you the direction right now, not the direction for the next 35 minutes. A patient who looks identical at minute zero and minute ten can still change at minute twenty, which is exactly why the interval keeps running instead of closing.
Only if the patient reports a new complaint during the ride: Waiting for the patient to volunteer a change hands your assessment to the patient. Plenty of real deterioration shows up in skin, pulse and mental status before the patient notices anything worth mentioning.
Question 2 of 10
An AEMT is transporting a 56-year-old patient who vomited a large volume of dark coffee ground material at home. The patient is pale and sweaty and answers questions slowly. The first set of vital signs is BP 96/70, P 118, R 22, and SpO₂ 95% on oxygen by non-rebreather mask. Five minutes later the vital signs are BP 92/68, P 124, R 24, and SpO₂ 95%. The receiving hospital is 30 minutes away. How often should the AEMT reassess this patient?
Show the answer and rationale
Correct answer · Every 5 minutes, and more often if the numbers keep moving
Pale, sweaty, slow to answer, a pulse climbing and a pressure sliding is an unstable patient, and an unstable patient gets a full reassessment every 5 minutes. That is the floor again, not the ceiling. This patient is moving in the wrong direction across a five minute window, which is the condition demanding more, so you keep looking more often than the clock requires and you tell the hospital what the trend is doing.
Why the others are wrong
Every 15 minutes, since the systolic is still above 90: A systolic above 90 is not a clean bill of health. Compensation holds the pressure up while the pulse climbs and the skin turns, which is precisely what these two sets show. Reading only the systolic is how a compensating patient gets put on a 15 minute schedule.
Twice more, spaced evenly across the remaining 30 minutes: Spacing checks evenly across the ride treats reassessment as a chore to be spread out rather than as monitoring. The interval is tied to how sick the patient is, not to how long the drive is.
Every 10 minutes, since the patient is still awake and answering: Mental status is one of the things you are rechecking, not the thing that sets how often you recheck. A patient answering slowly on a falling pressure and a climbing rate is unstable, and unstable buys the five minute clock.
Question 3 of 10
A 49-year-old patient fell about 12 feet from a hayloft onto a dirt floor and has diffuse abdominal tenderness. On first contact the radial pulses are present and regular, and the vital signs are BP 118/74, P 104, R 20, and SpO₂ 97% on room air. At the reassessment five minutes later neither radial pulse can be felt, though the carotid pulse is strong. What does that change tell the AEMT?
Show the answer and rationale
Correct answer · Perfusion is falling, so this patient is now a rapid transport
Reassessing circulation means checking a central pulse and a peripheral pulse, not one or the other, and the gap between them is the finding. A body that is squeezing down on the arms and legs to protect the brain and heart will drop the radial pulse while the carotid still pounds. That is compensation deepening in front of you. This patient just moved from potentially unstable to unstable, and the move earns rapid transport, oxygen and early notification rather than another quiet ten minutes.
Why the others are wrong
The arm was positioned poorly, so the radial pulse needs rechecking: Positioning is worth ruling out in one second, and it does not explain both sides going away together in a patient with abdominal tenderness after a fall. Chasing the technique buys time you do not have.
Perfusion is adequate, since the central pulse is still strong: A strong central pulse is what you would expect while compensation is still working. Reading it as reassurance is the same error as reading a normal blood pressure as no shock.
The bleeding has stopped, since the pressure held at the first check: Blood pressure is a late sign. A systolic that held at the first check tells you compensation was holding then, not that the bleeding stopped.
Question 4 of 10
A 9-year-old patient has had three days of vomiting and diarrhea and has taken almost nothing to drink since yesterday. The first set of vital signs is BP 98/62, P 132, R 24, and SpO₂ 98% on room air, with capillary refill of 2 seconds. Fifteen minutes later the vital signs are BP 96/64, P 150, R 26, and SpO₂ 98% on room air, and capillary refill is now 4 seconds. What do the two sets together tell the AEMT?
Show the answer and rationale
Correct answer · Perfusion is worsening, since a child's pressure holds until late
In children, heart rate and skin do the talking while the blood pressure sits still. A pulse that went from 132 to 150 with capillary refill doubling is a child compensating harder, and the nearly unchanged pressure is exactly what you would expect while that compensation is still working. Tachycardia is the early sign in a sick child. Waiting for the systolic to fall means waiting for compensation to fail, and in a child that failure is sudden.
Why the others are wrong
A fever is driving the pulse, since a rising temperature raises it: Fever does raise the pulse, and it does not lengthen capillary refill from 2 seconds to 4. The skin finding is the one that separates a warm febrile child from a child who is losing volume.
The two sets disagree, so a third set is needed before deciding: The two sets do not disagree. They agree completely once you know that pediatric blood pressure is the last number to move, and a third set only costs time.
Perfusion is stable, since the blood pressure barely moved at all: Reading the steady blood pressure as stability is the single most tested pediatric trap. In children the pressure holds until the child crashes, so it is the worst number to lean on.
Question 5 of 10
An AEMT is 15 minutes from the hospital with a 59-year-old patient who was alert and talking at the start of transport, with the vital signs BP 142/88, P 96, R 18, and SpO₂ 97% on oxygen. At the reassessment the patient answers only to a loud voice, and the vital signs are BP 104/86, P 126, R 26, and SpO₂ 93%. What should the AEMT do with this change?
Show the answer and rationale
Correct answer · Upgrade the priority, notify the hospital now, and escalate care
A patient can drop from stable to unstable at any point in a call, and when it happens three things move together: the priority goes up, the receiving facility hears about it now, and the care in the back of the truck escalates. All three, not one. Look at what changed here. Mental status fell, the pulse pressure narrowed from 54 to 18, the pulse jumped 30 and the saturation slipped. That is a patient losing ground, and the hospital needs the minutes your call buys them.
Why the others are wrong
Hold the report until arrival, when the whole picture is available: Saving the report for arrival costs the receiving team the only thing early notification buys, which is time to assemble people and open a room before the patient rolls through the door.
Repeat the vital signs in 15 minutes to confirm the trend first: Waiting fifteen minutes for confirmation is a third of the remaining trip. The second set already confirmed the first, and a trend that has declared itself does not need a tiebreaker.
Keep the current priority, since the patient still responds to voice: Responding to a loud voice is not the same as alert, and treating it as good enough ignores the direction. Mental status is the finding here, not the label you can still put on it.
Question 6 of 10
A 43-year-old patient was pinned briefly between a forklift and a wall and has abdominal pain and bruising across the flank. The AEMT is ventilating at a steady rate through a bag valve mask with waveform capnography in place. Ten minutes ago the vital signs were BP 116/78, P 104, and EtCO₂ 37 mmHg. The ventilation rate has not been changed, and now the vital signs are BP 106/76, P 122, and EtCO₂ 26 mmHg. What does the falling capnography value most likely mean?
Show the answer and rationale
Correct answer · Perfusion is dropping, since circulation delivers the carbon dioxide
The lungs can only blow off the carbon dioxide that blood carries to them. Hold ventilation still and the number stops being a breathing measurement and starts being a circulation measurement. A value that slid from 37 to 26 while the rate never changed, with the pulse climbing and the pressure easing down, is falling pulmonary blood flow. Reading that is squarely inside your scope, and it earns fluid, rapid transport and early notification rather than another quiet check.
Why the others are wrong
The patient is being ventilated faster than the rate that was set: Ventilating too fast does drive the number down, which is why the question fixes the rate. The rate did not change, so the explanation has to come from somewhere other than the bag.
The sampling line has come loose from the bag valve mask circuit: A disconnected sampling line is worth a two second look, and it produces a sudden loss of the waveform rather than a steady drift with a shape still present. The pulse and pressure moving alongside it point at the patient.
Ventilation has improved, so the value is settling toward normal: Normal is 35 to 45 mmHg, so 26 is below the range rather than settling into it. Calling a falling value improvement gets this exactly backward.
Question 7 of 10
A 48-year-old patient took a large dose of a prescribed sleep medication and is on oxygen by non-rebreather mask. Twenty minutes ago the vital signs were BP 124/78, P 88, R 14, and SpO₂ 97%. Now the vital signs are BP 118/74, P 84, R 6 with shallow chest rise, and SpO₂ 96%. What should the AEMT do next?
Show the answer and rationale
Correct answer · Begin positive pressure ventilation, since the saturation hides the rate
A pulse oximeter answers one question: how much of the hemoglobin arriving at that finger is carrying oxygen. It says nothing about how much air is moving or how much carbon dioxide is piling up, and a patient on high flow oxygen can read 96% while barely ventilating. Judge adequacy from rate, depth and effort. Six shallow breaths a minute is inadequate breathing no matter what the number says, so take over with a bag valve mask before the saturation catches up.
Why the others are wrong
Keep the mask in place, since a saturation of 96% shows good breathing: The reassuring number is exactly the trap. Oxygen delivered by mask props the saturation up for a while, and the saturation is the last thing to fall in a patient who is hypoventilating.
Insert a nasopharyngeal airway and recheck the saturation in 5 minutes: An airway adjunct helps a patient whose airway is obstructed, and nothing here says the airway is blocked. Waiting another five minutes at a rate of 6 lets the carbon dioxide keep climbing.
Apply continuous positive airway pressure to support the shallow breaths: Continuous positive airway pressure needs an awake patient with adequate spontaneous effort. A drugged patient breathing 6 times a minute has neither, and the tight mask adds an aspiration risk on top.
Question 8 of 10
A 54-year-old patient with a bleeding stomach ulcer had an intravenous line placed in the left forearm, and the vital signs at that time were BP 88/58, P 122, R 22, and SpO₂ 95% on oxygen. After 500 mL of normal saline the vital signs are BP 88/56 and P 124, the forearm above the site is puffy, cool and tight, and the drip is running slowly. What should the AEMT do next?
Show the answer and rationale
Correct answer · Stop the infusion and start a new line at a different site
Half a liter into a hypovolemic patient should move something, and nothing here moved. The arm is the answer: puffy, cool and tight above the site with a slow drip is an infiltrated line, and the saline has been going into the tissue rather than the circulation. An infiltrated line explains a patient who inexplicably failed to improve after volume. Stop it, take it out and establish access somewhere else, then give the fluid for real.
Why the others are wrong
Open the line wide, since 500 mL was not enough to raise the pressure: Opening a line that is not in the vein pushes more saline into the forearm and does nothing for the pressure. The failure to respond is the clue to check the site, not the reason to run faster.
Raise the fluid bag higher so gravity can overcome the resistance: Height changes flow rate, not location. The fluid would simply infiltrate faster into the same tissue.
Apply a warm pack to the arm and keep the current line running: A warm pack is a comfort measure for the swollen arm later, and it does not deliver a drop of volume to a patient who is bleeding. Leaving the line running keeps the damage going.
Question 9 of 10
A 68-year-old patient with a history of heart failure has had three days of diarrhea and poor intake. The vital signs were BP 88/60, P 118, R 20, and SpO₂ 94% on oxygen, with clear lung sounds. After 250 mL of normal saline the vital signs are BP 104/68 and P 104, and the lung sounds are still clear. What should the AEMT do next?
Show the answer and rationale
Correct answer · Give another small amount and listen to the lungs in between
This patient is dry from three days of diarrhea and the first 250 mL proved it, since the pressure came up and the pulse came down with the lungs still clear. A failing heart handles volume in small amounts rather than in a flood, so the pattern is smaller aliquots with reassessment between, not a standard bolus. Give the next small amount, then put the stethoscope back on the chest. The lungs tell you when to stop.
Why the others are wrong
Stop all fluid now, since the heart failure makes any more unsafe: Stopping now leaves a patient who is responding well still short of volume. A heart failure history is a reason to go carefully, not a reason to withhold fluid from someone who is dehydrated and improving.
Run a full liter wide open to finish correcting the fluid deficit: A liter wide open into a failing heart is how clear lungs become wet ones. The cardiac history is exactly what makes the speed the hazard here.
Switch to a slow maintenance drip and reassess at the hospital: A maintenance drip trickles in too slowly to keep correcting a real deficit, and deferring the reassessment to the hospital gives up the information the next few minutes would provide.
Question 10 of 10
A 75-year-old patient with advanced chronic obstructive pulmonary disease was found working hard to breathe, and the vital signs on first contact were BP 146/88, P 112, R 28, and SpO₂ 82% on room air. Oxygen was applied and titrated. Twelve minutes later the patient is drowsy and difficult to keep awake, the chest is barely moving, and the vital signs are BP 138/84, P 98, R 10, and SpO₂ 88% on oxygen. What should the AEMT do next?
Show the answer and rationale
Correct answer · Keep the oxygen on and begin positive pressure ventilation
Two things changed and they point in opposite directions. The saturation climbed from 82 to 88, so the oxygen is doing its job on oxygenation. The rate fell from 28 to 10, the chest is barely moving and the patient is hard to keep awake, so ventilation is failing and carbon dioxide is building. A saturation reading cannot see that. Never withhold oxygen from a hypoxic patient because they have chronic lung disease. If such a patient gets progressively drowsy on oxygen, that is the cue to support ventilation with a bag valve mask, not a cue to pull the oxygen off. Do both: oxygen stays, and you start breathing for the patient.
Why the others are wrong
Remove the oxygen, since the drowsiness started after it was applied: Taking oxygen away from a patient sitting at 88% makes the hypoxia worse within minutes, and hypoxia is what kills on that timescale. The drowsiness is a reason to add ventilation, never a reason to subtract oxygen.
Give a nebulized bronchodilator treatment and reassess in 5 minutes: A bronchodilator is the right drug for this disease and it may already be running. It opens airways for a patient who is still moving air, and a patient at 10 shallow breaths a minute is not moving enough to carry the drug in or to wait for it to work.
Check a blood glucose level to explain the new drowsiness: Glucose is worth knowing and it is quick, and new drowsiness is a fair reason to check it. Nothing it comes back as changes what has to happen in the next thirty seconds, which is air moving in and out of a chest that has nearly stopped.
