10 free AEMT practice questions: Advanced Trauma Interventions

Remove the soaked gauze and replace it with a dry dressing: Replacing a soaked dressing looks like good technique and keeps the wound tidy, which is why crews do it. Pulling the gauze off takes the forming clot with it, so the bleeding you were controlling starts over from the beginning.

Lift the dressing to find the exact bleeding point, then reapply: Finding the exact source seems like it would let you aim the pressure better, and precision is usually a virtue. Lifting to look is the specific action that strips the clot, and you can increase pressure over the same spot without ever seeing the vessel.

Elevate the arm above the heart while holding pressure: Elevation was taught for years and still feels intuitive, so it remains one of the most common answers here. It is no longer part of the hemorrhage control sequence, and reaching for it wastes time that belongs to added pressure or a tourniquet.

Loosen it slightly and add direct pressure over the wound: Loosening feels compassionate when a patient is in pain, and adding pressure sounds like you are combining two methods. Partial occlusion is the mechanism that worsens bleeding, and pain under a tourniquet is treated with analgesia, which is within your scope, rather than by loosening the device.

Leave it exactly as applied and cover it so that it is not disturbed: Bleeding that has slowed considerably looks like success, and disturbing a working tourniquet feels risky. Slowed is not stopped, and covering a tourniquet is its own error because the receiving team needs to see the device and the time written on it.

Move it closer to the wound and retighten it there: Moving closer to the wound seems like it would concentrate the pressure where the injury is. The correct placement is already two to three inches proximal, and repositioning costs time on a patient who is still bleeding while doing nothing about the real problem, which is that the device is not tight enough.

A dry sterile dressing secured with a pressure bandage: A dry dressing with pressure is the standard answer for most wounds you will treat, and the habit carries over. Gauze is porous, so air keeps moving through the chest wall defect in both directions and the lung on that side stays partly collapsed.

An occlusive dressing taped on all four sides: A four-sided seal is airtight and looks like the most thorough version of the treatment, which is why it is chosen so often. It gives trapped air no escape, and if the lung underneath is leaking, the pressure builds until venous return falls.

A petroleum gauze pad laid over the wound and left uncovered: Petroleum gauze is occlusive and is genuinely used on chest wounds, so half the reasoning is right. Left uncovered it does not stay sealed against the chest wall through movement and breathing, and it needs a backing taped in place to work as a seal at all.

Apply a cold pack and reassess before deciding to splint: Cold and reassessment are reasonable for a soft tissue injury, and the normal-looking wrist invites that read. Waiting for swelling to declare itself is the trap, because growth plate fractures frequently do not swell, and a child who will not use the arm has already told you something is broken.

Have the child move the wrist to judge whether it is broken: Asking a patient to move the joint is a common way providers try to sort a sprain from a fracture, and it feels efficient. Moving an injured growth plate can displace it, and range of motion does not reliably separate the two in a child.

Use a sling alone, since there is no deformity to immobilize: A sling supports the arm and is comfortable, which makes it feel like enough for an injury with no deformity. A sling alone does not immobilize the joint above and the bone below, so the injury keeps moving inside it every time the child shifts.

Packed directly in ice so the part stays as cold as possible: Colder sounds better when the goal is preserving tissue, and packing something in ice is how you would handle anything perishable. Ice in direct contact freezes and kills the tissue, so this is the version of the right idea that ruins the part.

Kept at room temperature in the warm patient compartment: Keeping the part with the warm patient is convenient and avoids any risk of freezing it. Tissue at body temperature keeps consuming oxygen it is no longer receiving, so warm storage burns through the window for reattachment quickly.

Submerged in cold sterile saline for the whole transport: Cold saline seems to combine cooling with the moisture the tissue needs, and moisture genuinely is part of the care. Soaking waterlogs the tissue rather than lightly moistening it, and the correct handling is gauze that is damp, not a part sitting in fluid.

Release the patient on scene after documenting a normal set of vital signs: Every finding you can measure is normal, and a patient who walked out and feels fine has a strong case for staying put. The mechanism is the finding here, and blast lung declares itself hours later in a patient whose first set of vitals looked exactly like this one.

Transport only if the patient develops difficulty breathing on scene: Using symptoms as the trigger is how you would triage most complaints, and it respects the patient's own report. Waiting for difficulty breathing puts the patient somewhere other than a hospital when it finally appears, which is the specific outcome the delayed-onset teaching exists to prevent.

Observe the patient on scene for about 20 minutes, then release if unchanged: A period of observation sounds like a reasonable compromise between transporting everyone and releasing everyone. Twenty minutes is nowhere near the window over which blast lung develops, so an unchanged patient at the end of it has not been cleared of anything.

Insert the device in the same tibia below the deformity: Staying distal to the break sounds like it would keep the infusion away from the injury, and it preserves the landmark you already found. The fracture is still between the needle and the heart, so fluid entering below it has to cross the break to reach the circulation and will extravasate along the way.

Make a third and a fourth peripheral attempt instead: More peripheral attempts feel safer than a device you use less often, and some providers are reluctant to commit to the intraosseous route in a small child. Two failed attempts in a decompensated child is already the point at which you stop, and a third and fourth attempt spend minutes this patient does not have.

Proceed at the planned site, since the marrow cavity is intact: The marrow cavity at the proximal tibia genuinely may be intact when the break is near the ankle, so the reasoning is not empty. The contraindication is written for the bone rather than for the segment, because a fractured bone leaks, and a device placed under that reasoning delivers fluid into the leg instead of the patient.

Aspiration of marrow to confirm placement: Aspirating marrow is a satisfying confirmation that the device is in the right space, and it is taught as one way to check placement. Its absence does not prove failure, so it is a helpful finding rather than a required step, and a device that stands upright and flushes cleanly is placed correctly whether or not marrow comes back.

Injection of lidocaine to reduce the pain of infusion: Lidocaine before the flush addresses real pain in a conscious patient, and skipping it can feel cruel. Whether an AEMT may give it is set by local protocol rather than by a national rule, so it is not the step that is mandatory everywhere, and it is never what makes the line flow.

A check of the distal pulse in that limb: Checking distal circulation is good practice after placing anything in a limb, and it carries over from splinting. An intraosseous device sits inside the bone and does not compress the vessels running past it, so the distal pulse is not the check that determines whether the line will run.

Withhold defibrillation and transport immediately, because this mechanism requires a paramedic to defibrillate: AED defibrillation is a basic-level skill available to the AEMT, not a paramedic-only intervention, so withholding it and simply transporting would delay the one action most likely to restore a perfusing rhythm.

Perform a pericardiocentesis to relieve suspected cardiac tamponade before defibrillating: Pericardiocentesis is not a field skill performed at this level, and the mechanism and sudden pulseless collapse point to commotio cordis causing ventricular fibrillation, not cardiac tamponade.

Delay CPR until IV access is obtained so epinephrine can be given first: High-quality CPR and defibrillation must not be delayed to obtain IV access or give medication; compressions and shocks take priority over establishing a line in this arrest.

Apply additional dressings over the trauma dressing and transport: Adding dressings on top is the right move for venous or capillary bleeding that has already slowed and only needs reinforcement while pressure continues. This blood is bright red and pulsing through a trauma dressing under firm pressure, which is arterial and not slowing. Every layer added moves the pressure further from the vessel, so the stack soaks up blood while the bleeding continues underneath, the opposite of what packing does.

Elevate the extremity and apply pressure at a proximal pressure point: Elevation and proximal pressure points are the classic legacy answer, taught for years and still the first thing many students reach for. Both were removed from current bleeding-control teaching because neither reliably stops arterial hemorrhage, and both consume time that belongs to the technique that works. Elevation is also meaningless for a groin wound, since there is nothing distal to raise, which leaves the key as the only real escalation.

Apply a tourniquet as high on the thigh as it will fit: A tourniquet is the correct next step for an arterial extremity bleed when there is limb above the wound to compress, and reaching for one is the right instinct. The question closes it: the wound is too proximal for a device to fit above it. A tourniquet placed at or below the level of the injury cannot occlude the artery feeding it and may raise venous pressure enough to increase the bleeding, so the key uses the technique designed for junctional wounds instead.
