10 free AEMT practice questions: Bleeding Control and Hypovolemic Shock

Until the bleeding stops while the radial pulse is preserved: Keeping a pulse in a hand you want to save is a humane instinct and sounds like careful titration. A band tight enough to stop venous return while arterial blood still arrives makes the bleeding worse rather than better, so this setting is the one failure mode the device has.

Until the bleeding slows to an ooze and the fingers stay warm: An ooze looks like success after a heavy arterial bleed, and warm fingers seem to confirm the limb is doing well. Continued oozing under a locked windlass means the device is under tightened, and that half tight state is precisely what increases blood loss.

Until the patient reports that the pressure has become painful: Pain is a genuine consequence of a correctly applied tourniquet and it does grow the longer the device is on. Pain arrives well before arterial occlusion, so tightening to a pain report stops short of the endpoint and treats the patient's report as the measurement instead of the bleeding.

The device has failed and should be exchanged for a pressure dressing: Swapping a device that appears not to be working is a reasonable troubleshooting instinct anywhere else. The device has not failed here; it has been left in the one setting that makes bleeding worse, and taking it off to apply a dressing gives up arterial control entirely.

Venous bleeding that a tourniquet is not designed to control: The dark color genuinely does suggest venous blood, so the reasoning has real evidence behind it. A properly tightened tourniquet stops venous and arterial flow both, and the reason venous blood is leaving is that arterial blood is still arriving underneath a partly tightened band.

Normal residual drainage from the vessels inside the tourniquet: Some ooze from the tissue inside a tourniqueted limb sounds plausible and gives a comfortable reason to stop adjusting. Steady bleeding is never the expected endpoint, and accepting it as normal leaves the patient losing volume under a device that is supposed to have stopped it.

Cover it with a blanket so the patient does not look at it: Covering an unpleasant injury is a kind instinct and patients do ask for it. A tourniquet that the receiving team cannot see is the specific thing the guidance rules out, because the device and its time are what drive the next decision about the limb.

Loosen it slightly now that the bleeding has stopped: Bleeding that has stopped feels like a reason to reduce the injury the device is doing. Loosening lets arterial blood back into a vessel that has not been repaired, and once a tourniquet is on in the field it is not loosened or periodically released.

Note the time on the patient care report and cover the limb: Writing the time down is right, and the patient care report is where most times belong. This one belongs on the device itself so it arrives with the limb, and covering the limb hides the very thing the hospital has to see.

Pack the tract with hemostatic gauze and hold pressure over it: Hemostatic gauze is genuinely the right tool for a bleed pressure cannot control, and the instinct to escalate is correct. The abdomen is a cavity rather than a tract, so gauze fed in cannot reach or compress the source, and packing it delays the only thing that helps this patient, which is transport.

Wrap a pressure dressing circumferentially around the abdomen: A circumferential wrap is how you secure a pressure dressing on a limb, and it feels like the way to apply pressure to a trunk. A belly is compressible and holds a large volume, so a wrap compresses bowel rather than a vessel and gives no meaningful hemorrhage control.

Probe the wound with a gloved finger to find the bleeding vessel: Finding the vessel sounds like the shortest route to stopping the bleeding, and it is how the problem gets solved surgically. Probing a penetrating abdominal wound disturbs clot, can extend the injury, and is outside what any field provider does with this wound.

Removed, with the tract packed with hemostatic gauze: Removing the object and treating the wound underneath feels like getting to the real injury. The object is tamponading the vessel, so pulling it releases bleeding you then cannot reach, and packing a thigh tract is no substitute for the plug that is already there.

Removed only if it interferes with moving the patient: Movement is a real problem with a long impaled object, and the practical pressure to deal with it is genuine. Stabilizing and padding solves the movement problem without releasing the tamponade, which is why removal stays off the table.

Shortened at the skin, with the cut end covered by a dressing: Shortening a long object is something specialized rescue teams do occasionally, so it has a ring of truth. Cutting transmits movement and vibration straight into the wound, and it is not a field maneuver for a routine impalement.

Leave it alone, since loosening it restarts the bleeding: Do not disturb the dressing is a real rule, drilled hard, and it guards against tearing away a clot you cannot see. It answers bleeding, not circulation, and the cool pale fingers with new tingling are telling you about circulation.

Tighten it further until the fingers stop tingling: Tightening to make a symptom stop has a certain logic if you read the tingling as bleeding under the bandage. More compression deepens the ischemia that is causing the tingling, and it moves the dressing toward being an accidental tourniquet.

Replace it with a tourniquet above the elbow: Escalating to a tourniquet feels decisive and this bandage does appear to be failing at something. The bleeding was already controlled, so a tourniquet adds deliberate ischemia to an arm whose only problem is a bandage that needs loosening.

A child bleeds faster than an adult from the same size wound: Children do bleed briskly from scalp wounds, so this feels close to something true. Rate is not what makes the loss dangerous here; the same volume is simply a far bigger fraction of a smaller tank.

A child's clotting system responds more slowly to an injury: A slower clotting response would explain a larger loss and sounds physiologically plausible. A healthy child's clotting is not impaired, so the difference is the size of the circulating volume rather than the ability to stop the bleed.

Scalp wounds bleed more heavily in children than in adults: Scalp wounds genuinely bleed out of proportion to their size at any age, which gives this real footing. That explains why 600 mL ended up on the floor, not why 600 mL means more in this patient than in an adult.

It is acceptable in a teenager whose bleeding has been controlled: A controlled bleed feels like the emergency is over, and teenagers do tolerate a lot before they look sick. Stopping the loss does not restore what is already gone, and a systolic of 84 over age ten sits below the threshold regardless of what the tourniquet accomplished.

It is expected after a tourniquet and will rise without treatment: Patients do sometimes improve once a bleed is controlled, so waiting for the number to come up is tempting. A pressure that low reflects a volume deficit that only replacement and a hospital correct, and watching it is time this patient does not have.

It is above the 70 mm Hg pediatric floor, so it does not count as low: There is no single pediatric floor. The number climbs with age: 70 for an infant under one year, 70 plus twice the age in years from one to ten, and the adult 90 over age ten. A 16-year-old sits on that last rung, so 84 is below the line and this is hypotension.

A saturation that comes back above 94 percent: Saturation tells you how loaded the blood is, not how much of it is left or where it is going. A patient who has lost a third of their volume can still read 96 percent.

Two liters of crystalloid given, whatever the numbers do: A fixed volume is not an endpoint. Fluid here is titrated to what the patient shows you, and a set number of bags either stops short or overshoots into a pressure that reopens the clot.

A capillary refill time of less than two seconds: Capillary refill is a real perfusion measure and it belongs in the reassessment. It is slow to change and unreliable in a cold patient, so the endpoint that the guidance names is the radial pulse paired with mental status.

A warm patient reports less pain during a long transport: Shivering patients are miserable and warmth is genuinely kind, so the reasoning holds up as far as it goes. Framing warming as comfort puts it at the bottom of the priority list, when it belongs beside the dressing as hemorrhage control.

Warming raises the blood pressure toward a normal range: Warming a cold patient can improve perfusion, so there is a grain of truth in the mechanism. The pressure is not what warming is for, and treating it as a way to move a number misses that the target in an uncontrolled bleed is deliberately held low anyway.

Cold skin makes the pulse oximeter read falsely low: Cold fingers genuinely do degrade a pulse oximeter reading, so this is a real clinical effect. It is a monitoring nuisance rather than the reason warming is treatment, and the saturation reading is not what hypothermia is threatening here.
