10 free EMT practice questions: Shock (All Types) & Hemorrhage Control

Apply an occlusive dressing first, then a tourniquet: The occlusive dressing is absolutely indicated and is the very next step after the tourniquet, so the treatment named here is not wrong, only its place in the order is. Sealing the chest first leaves an arterial thigh wound spurting for as long as it takes to expose, seal, and secure that dressing. The key does the intervention that takes seconds and stops the fastest killer, then moves to the chest.

Manage both wounds simultaneously: Simultaneous management is what actually happens on a scene with enough providers, and with two crews present both wounds would be handled at once. The question asks for an order, which is the situation a single provider faces, and refusing to prioritize means both wounds get partial attention. The reasoning still lands in the same place: the tourniquet goes on first.

Assess the chest wound only; it is always the priority: Chest wounds command attention, and a sucking sound with each breath is dramatic enough to pull you toward it. Always is the wrong word: massive hemorrhage precedes airway and breathing in the trauma sequence precisely because arterial bleeding is the fastest cause of death in trauma. Assessing only the chest leaves the thigh bleeding unaddressed, which is the error this option encodes.

Nasal cannula at 2-3 L/min to avoid overoxygenation: Low-flow nasal cannula is the right device for the comfortable patient with mild hypoxia who will not tolerate a mask: the COPD patient at home on 2 liters, the stable chest-pain patient with a saturation in the low nineties. It is the wrong device here for a simple reason: this patient has a systolic of 80 and one functioning lung, and there is no such thing as overoxygenating a patient in shock during an ambulance transport. Withholding oxygen to avoid a theoretical harm while a real one is unfolding gets the priority backwards.

BVM ventilation at 20 breaths/min with 15 L/min of oxygen: BVM ventilation is correct for the patient whose own respiratory effort is inadequate: too slow, too shallow, or absent. This patient is in severe difficulty but is still breathing on their own, and positive pressure carries a specific danger in tension pneumothorax: every forced breath pushes more air into the pleural space and raises intrathoracic pressure, worsening the venous return that is already failing. If this patient's effort fails you will ventilate, carefully and at a normal rate rather than 20 breaths a minute, but you do not begin there.

Room air until the paramedic arrives to decompress the chest: Room air is what you leave a patient on when there is neither hypoxia nor shock. Here there is both, and waiting for the paramedic is not a treatment plan. It is an interval you are supposed to fill with the highest oxygen concentration you can deliver plus movement toward definitive care. The correct answer covers the same waiting period, spent doing the one thing that helps.

The patient is recovering; the drop in systolic pressure means his heart rate is normalizing: Incorrect. Heart rate remains elevated (tachycardia persists); falling systolic pressure combined with worsening mental status indicates deterioration, not improvement.

The patient is developing hypertension and will improve shortly: Incorrect. Blood pressure decreased, not increased. Hypertension is not present in this clinical picture.

The patient's condition is stable and no change in care is needed: Incorrect. The change from baseline to hypotension and deteriorating mental status is a critical finding that mandates reassessment and possible escalation of care.

The patient is in decompensated shock and requires immediate high-concentration oxygen and rapid transport: Decompensated shock requires hypotension or severely altered mental status, and this patient has neither: the blood pressure is 122/78 mmHg and orientation is intact, so the staging label is wrong even though oxygen and prompt transport are reasonable for any shock patient.

The patient is experiencing anxiety from the collision, and the rapid pulse and moist skin reflect an emotional response: Attributing the presentation to an emotional response ignores the objective perfusion findings: tachycardia at 110/min with pale, moist skin in a patient with a femur fracture points to early compensated shock, not anxiety alone.

The patient's blood pressure and respirations are within normal limits, indicating perfusion is currently adequate: A normal blood pressure does not mean perfusion is adequate: pressure is maintained by compensation in early shock, and the tachycardia and pale, moist skin show that compensation is already underway.

The patient's condition is stable because the blood pressure has not significantly changed: Calling the patient stable because blood pressure hasn't changed ignores that skin and perfusion signs change before blood pressure drops: the pallor, diaphoresis, and rising heart rate are the earlier warning signs.

The vital signs show only minor changes and do not warrant urgent intervention: Calling these only minor changes not warranting urgent intervention misses that this trend, warm/dry to cool/clammy with rising heart rate, is exactly the pattern that precedes decompensation.

The patient's heart rate increase is a normal response to chest pain anxiety and does not indicate shock: Attributing the rising heart rate to anxiety alone dismisses the objective trend in skin findings that developed alongside it, which together point toward worsening perfusion.

Reflex bradycardia is blunting the force of each ventricular contraction: A student may recall that some conditions slow the heart, but cardiac tamponade produces tachycardia, not bradycardia, as the heart tries to compensate for the falling stroke volume.

Ongoing blood loss from the chest wound is lowering the total volume of circulating blood: A student may default to a hypovolemic explanation for any narrowing pulse pressure, but this patient's findings, jugular vein distention and muffled heart sounds, describe fluid accumulating around the heart rather than fluid lost from the vessels, and there is no reported external bleeding.

Peripheral vasoconstriction is raising the systolic and diastolic pressures equally: A student may know vasoconstriction is part of the shock response, but raising both pressures equally would not narrow the pulse pressure; the tamponade mechanism instead raises diastolic while lowering systolic.

Cardiogenic shock: results from a primary heart problem and does not explain the fever, which points to an infectious process.

Neurogenic shock: requires a spinal cord injury, which is not described here.

Hypoglycemia: Nothing in this presentation is grounded in a blood glucose finding, and the fever with gradual decline points to infection rather than a glucose-related cause.

Leave the wound completely uncovered to allow air to escape: Leaving the wound completely uncovered lets air continue moving in and out through the chest wall defect with every breath, worsening the patient's ability to ventilate.

Perform needle decompression of the affected side: Needle decompression is a paramedic-level intervention reserved for a developing tension pneumothorax, not the initial EMT-level management of an open chest wound.

Pack the wound tightly with gauze to stop air movement: Packing the wound tightly with gauze doesn't create the airtight seal an occlusive dressing provides, and it can still allow air movement through the wound.

Withhold further treatment until the blood pressure improves: You'd pick this if waiting for confirmation felt like the cautious move. His absent radial pulse and pressure of 78/50 already show decompensated shock, so delaying care lets a treatable emergency get worse instead of better.

Give the patient sips of water: You'd pick this if you were focused on replacing fluid by mouth. This patient is confused, which means he can't reliably protect his own airway, so giving him water by mouth risks aspiration instead of helping him.

Apply ice packs to the skin: You'd pick this if you were thinking of managing a fever rather than shock. Cooling the skin does nothing for the volume this patient has lost, and a shock patient needs to be kept warm, not cooled.

Hypovolemic shock: You'd pick this if the low blood pressure and the fast pulse made you think of blood loss. Nothing in the story points to bleeding or fluid loss, and the arm pain and nausea point straight at the heart.

Septic shock: You'd pick this if the semiconscious state made you think of an infection. Septic shock comes with a fever and a source of infection, and his history has neither.

Obstructive shock: You'd pick this if the breathing trouble made you think something was blocking blood flow. Obstructive shock comes from a tension pneumothorax, cardiac tamponade, or a large clot in the lungs, and there is no mechanism or history for any of those.
