10 free AEMT practice questions: Field Impression Formation

Acute myocardial infarction: Naming acute myocardial infarction states a diagnosis rather than an impression. The presentation looks classic, and a specific name sounds more useful on the radio. Confirming an infarction takes serial laboratory work and imaging that no ambulance carries, and once you have said it out loud you tend to stop looking for anything else.

Noncardiac chest wall pain: Calling the discomfort noncardiac closes the most dangerous possibility off the list before anything has ruled it out. It is the wording that sounds most decisive on the radio. Cool, diaphoretic skin in a patient with chest discomfort is exactly the pattern that keeps a cardiac cause near the top.

Chest discomfort, as the patient reported it: Quoting the patient back feels like the safest thing you can say on a radio, especially after a warning about overreaching. The chief complaint is what the patient says is wrong, while the impression is what the provider concludes is happening, and a report that stops at the complaint hands the hospital nothing the patient did not already say. Staying inside your scope means hedging the impression, not declining to form one.

Pelvic fracture: fits the down-and-under pathway, where an unrestrained driver's knees and legs drive into the dashboard, loading force up through the femurs into the pelvis. The bent steering wheel points to the up-and-over pathway instead, where the chest strikes the wheel. Same crash, different body region.

Spinal cord injury: the clue you look for with axial loading: diving into shallow water, a fall landing on the head or feet, or a rollover that compresses the spine along its length. A collapsed steering wheel shows a forward chest impact, not axial compression, so it points to the thorax, not the cord.

Burn injury: follows a fire, exploded airbag propellant, hot fluids, or electrical contact at the scene, none of which a bent steering wheel tells you happened. Steering wheel deformity is a blunt trauma clue for the chest, unrelated to a thermal mechanism.

An isolated injury to the head only (scalp, skull, and face): An isolated head injury is what you predict when all the energy lands at one point on the skull: a falling object, or a blunt assault. A tumbling stair fall spreads that energy across several surfaces instead. The alert-and-oriented detail is also the part that leads crews to under-triage this mechanism; a normal mental status says nothing about the ribs, pelvis, or spine you have not palpated yet.

Isolated fractures of the lower extremities only (ankles, tibias, and femurs): Isolated lower-extremity fracture is the pattern for a controlled feet-first fall from height, where force travels up the axial skeleton from the heels and produces the calcaneus, tibia, and lumbar spine injuries that go with it. A stair fall is not a controlled landing; the patient rotates and strikes with whatever leads. Lower-extremity injury is genuinely likely here, so what makes the option wrong is the word only.

Soft-tissue injuries only, without bone involvement (bruising and abrasions): Soft-tissue injury with no bone involvement describes a low-energy event, like a slip onto a flat floor from standing in a younger patient. Twelve steps carries more energy than that, and an older adult's skeleton tolerates less of it. Expecting bruising alone is how a hip, rib, or spinal fracture gets missed, because you never perform the palpation that would have found it.

Hip dislocation and pelvic ring injury: Lap belts do load the pelvis and cause hip injuries, which pulls hard here if the belt's actual position goes unchecked. Hip dislocation is the pattern for a belt worn too low, below the iliac crests, and the question places the belt mark well above the hip bones.

Clavicle fracture and sternal injury: The diagonal shoulder strap of a three-point restraint loads the clavicle and sternum. The question states the rear seat is fitted with lap belts only, so no shoulder strap crossed this patient's chest.

Cervical spine and facial injury: Any head-on collision suggests whiplash and facial impact. The question states the patient denies neck pain and has no facial injury, and a rear-seat occupant restrained at the waist is not thrown forward into the windshield.

The injuries are confined to the line between the two wounds: Tracing a straight line between two wounds is the simplest way to guess what was hit, and it is roughly true for a knife or another low-energy penetration. A rifle round is medium to high velocity, so it may flatten, tumble, or ricochet inside the body, and the pressure changes around it damage tissue away from its path.

The smaller wound is the entrance and predicts the depth of injury: Entrance wounds are usually described as small and neat and exit wounds as larger and ragged. Entrance and exit cannot be reliably told apart in the field, and identifying one would still not tell the AEMT how deep the injury runs; the AEMT counts the wounds and treats what is found.

The size of the larger wound reflects the amount of internal damage: A bigger hole looks like a bigger injury. External wound size does not track internal damage in penetrating trauma, and this patient's abdominal findings and vital signs already point to damage far larger than either skin wound.

Wrist injury, because a falling child extends the arms to break the fall: Catching yourself on an outstretched hand is the adult reflex, and wrist fracture is the classic adult low-fall injury. A toddler's head is proportionally much heavier than an adult's, so the head, not the hands, arrives first.

Ankle and knee injury, because the legs absorb the energy of a short fall: A feet-first landing does load the legs, transmitting energy through the calcaneus, the pelvis, and the spine. That applies to a patient who lands on the feet; a top-heavy toddler going over an edge does not.

Clavicle injury, because the shoulder takes the first impact in a low fall: Clavicle fracture is a common pediatric injury and is easy to attach to any fall. It follows a fall onto the shoulder or the outstretched arm, not the head-leading fall a toddler's body proportions produce.

A definitive diagnosis of the underlying disease process, confirmed by the AEMT's assessment in the field: You'd pick B if you're thinking of what a physician does in the ED, confirming a disease process with imaging and labs. An AEMT's scope stops short of that certainty, so calling a field impression a definitive diagnosis overstates what the AEMT is actually allowed to claim in the field.

A single vital sign or physical exam finding that by itself determines the patient's chief complaint: This fits a moment where one number, like a glucose reading or an SpO2 value, drives a specific intervention on its own. A field impression isn't that: it's the pattern across history, exam, and context, with any single finding folded into that broader picture rather than standing alone as the answer.

An immediate general impression formed during the first 30-60 seconds of contact, before history or exam findings are gathered: This describes the general impression, the snap judgment of how sick the patient looks, formed in the first 30-60 seconds from appearance, breathing, and skin signs, before history or exam findings exist. Both are impressions carried through the call, but the general impression comes first and stays unrefined; the field impression follows and keeps updating as data accumulates.

Tension pneumothorax: Chest trauma with distended neck veins and a falling blood pressure is the memorized pattern for tension pneumothorax. Trapped air collapses the lung on the injured side, so that condition produces unilateral decreased or absent breath sounds and, as a late sign, tracheal deviation toward the unaffected side. The question states breath sounds are clear and equal in all fields and the trachea is midline.

Hemothorax: Blunt chest trauma with shock and no external bleeding is the textbook trigger to suspect bleeding into the chest. A hemothorax compresses the lung on the affected side, producing decreased breath sounds there, and it drains circulating volume rather than distending the neck veins. The question reports equal clear breath sounds and distended neck veins.

Intra-abdominal hemorrhage: A steering wheel mechanism with a rapid pulse and a low blood pressure reads as blood loss somewhere unseen. Falling volume empties the neck veins and does not muffle the heart sounds, and the question reports distended neck veins, muffled heart sounds, and a soft, nontender abdomen.

Hypovolemic shock: Any trauma patient with a low blood pressure is assumed to be bleeding somewhere. Hypovolemic shock presents with tachycardia and pale, cool, clammy skin, and the question reports a pulse of 52 with warm, dry skin, no bleeding, a nontender chest, and a soft abdomen.

Cardiogenic shock: A slow pulse paired with a low blood pressure suggests the heart has failed as a pump. Cardiogenic shock follows damage or disease of the heart itself and commonly brings chest discomfort and fluid backing into the lungs; the question gives a diving mechanism, no chest discomfort, and clear breath sounds in all fields.

Psychogenic shock: A sudden collapse after a frightening event sounds like fainting. Psychogenic shock is a brief, temporary reduction in blood supply to the brain that ends once the patient is supine, and the question states the patient never lost consciousness and is alert while still hypotensive.

Pneumonia: Chest discomfort with fast breathing and a low oxygen saturation reads as a lung infection. Pneumonia builds over days and brings fever, cough, and abnormal sounds over the affected lobe; the question reports an onset that was sudden while walking, no fever, no cough, and breath sounds clear and equal in all fields.

Acute pulmonary edema: Sudden difficulty breathing with a low oxygen saturation in a middle-aged patient suggests fluid backing into the lungs. Fluid in the alveoli produces crackles and, when severe, pink frothy sputum; the question reports breath sounds clear and equal in all fields.

Spontaneous pneumothorax: Sudden one-sided chest discomfort that worsens with each breath is the description that goes with air escaping into the chest. A pneumothorax collapses the lung on that side and produces decreased or absent breath sounds there; the question reports breath sounds clear and equal in all fields.
