Question 1 of 10

A 35-year-old fell approximately 15 feet from a ladder onto a concrete surface. On primary assessment, the patient responds only to painful stimuli, having been alert on the EMT's arrival minutes earlier. Airway is patent, breathing is rapid and shallow at 26/min, and radial pulses are weak and rapid. There is bruising over the flank and mild abdominal distension. Which finding makes this patient a load-and-go priority, and what should the EMT do?

Show the answer and rationale

Correct answer · The declining mental status and ABC findings, then immediate transport

This patient is a load-and-go priority because the mental status is getting worse. The patient was alert when you arrived and now responds only to pain minutes later. A dropping level of consciousness means the brain is not getting enough blood flow or oxygen right now. The fall makes you suspect injury, and the findings in the primary assessment set the priority. Breathing and circulation are failing too. Breathing is rapid and shallow at 26, so each breath moves too little air. The radial pulses are weak and rapid. Weak, rapid radial pulses point to a narrowing pulse pressure and the body shutting down blood flow to the arms and legs. The flank bruising and abdominal distension point to the likely source, bleeding in the abdomen or in the retroperitoneal space behind it. The source does not change the plan. Treat the life threats, package the patient, and transport. Do the detailed exam on the way.

Why the others are wrong

The fall mechanism alone, then a full secondary exam on scene: The fall is a real trauma triage criterion. A fall of about three times body height onto concrete is a good reason to go to a trauma center. The mechanism only makes you suspect injury, and plenty of patients survive a fall like this with minor injuries and normal vital signs. The bigger problem with option A is the full secondary exam on scene. This patient is getting worse, and every minute on scene is a minute the bleeding goes untreated.

The flank and abdominal findings, then a full abdominal exam on scene: The flank bruising and abdominal distension are real findings, and they point to where the bleeding is coming from. A full abdominal exam on scene does not change anything you can do about that bleeding. The only EMT treatment for bleeding inside the abdomen is transport. The declining mental status is what tells you how fast to move.

The patent airway, which rules out load-and-go, then a full exam on scene: A patent airway is good news, and checking the airway is the right first step of the primary assessment. The airway is only one part of that assessment. Breathing, circulation, and mental status are all abnormal in this patient. An open airway does not stop a patient from bleeding to death, so a patent airway cannot rule out load and go.

Question 2 of 10

A 26-year-old patient sustains a gunshot wound to the left chest. The EMT hears a sucking sound with each breath at the wound site. No commercial occlusive chest seal is available on the unit. What is the most appropriate EMT action?

Show the answer and rationale

Correct answer · Use any air-occlusive material, taped on three or four sides

This patient has an open pneumothorax, a sucking chest wound. The sucking sound is air moving in through the hole in the chest wall instead of through the trachea. When the hole is big enough, air takes that shortcut, and the lung on that side collapses as outside air fills the pleural space. You do not need a commercial chest seal to fix this. Anything air cannot pass through, taped down over the wound, closes the hole. Plastic wrap, the sealed wrapper the dressing came in, or the backing from a defibrillator pad all work. Taped on three sides, the dressing lets air out of the pleural space and blocks air from coming in. Taped on four sides, the dressing seals completely. Watch the patient closely and lift the dressing right away if signs of tension pneumothorax show up.

Why the others are wrong

Leave the wound uncovered until an occlusive dressing arrives: An uncovered hole keeps letting outside air in with every breath, and the lung stays collapsed for the whole transport. You do not need a commercial seal, only material that air cannot pass through. Cover the wound now, and lift the dressing if tension signs show up, because a fully sealed dressing can turn an open pneumothorax into a tension pneumothorax.

Cover the wound with a dry gauze dressing secured with tape: Gauze is porous, so air passes straight through it and the pleural space keeps filling. Taping gauze down changes nothing for this patient. This wound needs material that blocks air.

Pack the wound tightly with gauze to stop air movement: Packing is contraindicated in the chest. Gauze pushed through a chest wound goes into the pleural space, can injure the lung, and is hard to get back out. Packing also does not stop air from moving in around the gauze.

Question 3 of 10

A 33-year-old patient is involved in a motorcycle collision and has an open fracture of the tibia with obvious bleeding, now controlled with direct pressure, and also reports increasing difficulty breathing. The EMT notes diminished breath sounds on the left and a respiratory rate of 26 breaths per minute with shallow effort. What should the EMT prioritize?

Show the answer and rationale

Correct answer · Support ventilation and manage the chest injury first

This patient has a chest injury with failing breathing. The breath sounds are diminished on the left, and the respirations are 26 a minute with shallow effort. The patient reports increasing difficulty breathing, so the breathing is getting worse. The bleeding from the open tibia fracture is already controlled with direct pressure. The primary assessment order sorts out which problem comes first. A breathing problem can kill in minutes, and a long bone fracture with the bleeding controlled does not. Support ventilation and manage the chest first, then finish splinting the tibia on the way. Supporting ventilation also lets you reassess whether the chest injury is getting worse.

Why the others are wrong

Splint the tibia fracture first to control bleeding: Splinting a long bone helps control bleeding and pain. Splinting would come first if the bleeding were still uncontrolled, because an open tibia fracture can bleed a lot. This question says the bleeding is now controlled with direct pressure. A controlled bleed is no longer the life threat, and failing breathing kills sooner.

Obtain a detailed pain assessment before addressing breathing: A detailed pain assessment belongs in the secondary assessment, after the life threats are handled. Asking pain questions while the tidal volume falls spends the most important minutes on information that will not change what you do next.

Elevate the injured leg before assessing the chest: Raising an injured leg is taught as an add on for bleeding control. The bleeding here is already controlled. Raising the leg does nothing for the chest. In the primary assessment, breathing comes before anything you do for the leg.

Question 4 of 10

A patient sustains a gunshot wound to the thigh with spurting bleeding and a separate gunshot wound to the chest that produces an audible sucking sound with each breath. Which of the following is the most appropriate order of initial EMT actions?

Show the answer and rationale

Correct answer · Apply a tourniquet first, then an occlusive dressing

The tourniquet goes on first. The thigh wound has spurting bleeding, and spurting bleeding is arterial. A patient can bleed to death from an artery in the thigh in a few minutes. A tourniquet takes seconds to put on, and it controls the bleeding. That is why the trauma sequence puts massive bleeding ahead of airway and breathing. The sucking chest wound is still a real breathing problem. Air is being pulled into the pleural space through the wound with each breath. That air can build into a tension pneumothorax. The harm from the chest wound builds over minutes, not seconds. Put the occlusive dressing on the chest right after the tourniquet.

Why the others are wrong

Apply an occlusive dressing first, then a tourniquet: Sealing the chest first leaves the thigh artery spurting while you expose the chest, seal the hole, and secure the dressing. The occlusive dressing goes on right after the tourniquet.

Manage both wounds simultaneously: Splitting your attention between two wounds gives each one only part of the care it needs. Working both at once takes enough providers, like two crews on scene. With one provider, the tourniquet still goes on first, because a patient can bleed to death from an artery in the thigh in a few minutes.

Assess the chest wound only; it is always the priority: The thigh is spurting, so the chest is not the first priority. Massive bleeding comes before airway and breathing in the trauma sequence, because arterial bleeding is the fastest cause of death in trauma. Looking only at the chest leaves the thigh bleeding with nobody controlling it.

Question 5 of 10

A worker at an industrial site was stabbed in the chest during an altercation. The patient is alert with difficulty breathing. When the EMT exposes the chest during the primary assessment, a wound on the right side bubbles and makes a sucking sound with each breath. What should the EMT do immediately?

Show the answer and rationale

Correct answer · Cover the wound with an occlusive dressing

This patient has an open pneumothorax from a sucking chest wound. The wound on the right side bubbles and makes a sucking sound with each breath. Air is getting pulled in through the hole in the chest wall instead of through the airway. Air in the pleural space collapses the lung on that side. That's why this patient is having trouble breathing. Cover the wound with a gloved hand right away. Then seal it with a vented chest seal, or an occlusive dressing taped on three sides. Do not tape all four sides. A seal taped on all four sides lets air in but not back out, and that's how you create a tension pneumothorax. Give high-concentration oxygen, reassess constantly, and transport fast.

Why the others are wrong

Auscultate the breath sounds on the right side: Listening to breath sounds is how you pick up a pneumothorax when there is no open wound to see. This patient already shows you the problem, because the wound bubbles and sucks air with each breath. Seal the wound first. Listen to the breath sounds after.

Begin positive pressure ventilations with a BVM: A bag-valve mask helps a patient who is not moving enough air on their own. Bagging does nothing to close the hole in the chest wall. The wound gets sealed first, and you assist ventilations after that only if this patient needs it.

Place a bulky gauze dressing over the wound: A bulky dressing is what you use to hold an impaled object in place. Gauze is not occlusive. Air keeps moving through gauze and into the chest, so this wound needs an airtight seal.

Question 6 of 10

A 26-year-old patient was stabbed during an altercation outside a nightclub. The patient is anxious and reports difficulty breathing. During the primary assessment the EMT finds a wound on the left chest wall that makes a hissing sound as air moves through it with each breath. Which injury do these findings indicate?

Show the answer and rationale

Correct answer · Open pneumothorax

This patient has an open pneumothorax. The wound on the left chest wall makes a hissing sound as air moves through the wound with each breath. When the patient breathes in, air gets pulled through the hole in the chest wall into the pleural space. When the patient breathes out, the air gets pushed back out the hole. The pressure inside the chest should stay negative. With the hole open, the pressure in the pleural space evens out with the air outside. A closed chest injury does not move air in and out through the chest wall. Seal the wound with an occlusive dressing taped on three sides. Give high-concentration oxygen. If signs of tension develop, release the dressing to let the trapped air out. Transport rapidly.

Why the others are wrong

Tension pneumothorax: An open wound can turn into a tension pneumothorax as trapped air builds pressure in the chest. Tension shifts the trachea and drops the blood pressure. You would see absent breath sounds, low blood pressure, or jugular vein distention, and none of those are in this question. Tension is the complication you watch for after you seal this wound.

Flail chest: a section of the chest wall broken loose by several rib fractures. That section moves the opposite way from the rest of the chest during breathing. This patient has a hissing wound, not a chest wall moving the wrong way.

Hemothorax: A hemothorax is blood collecting in the pleural space. A hemothorax gives you diminished breath sounds and signs of shock. Blood in the chest does not make a hissing sound at a chest wall wound.

Question 7 of 10

A 28-year-old patient presents after blunt perineal trauma from a fall while hiking. The patient reports heavy vaginal bleeding. The primary assessment reveals an alert, oriented patient with a patent airway and adequate breathing. Vital signs: BP 118/72 mmHg, P 92/min, R 16/min. The patient is otherwise hemodynamically stable with no other injuries noted. What is the appropriate EMT management for the active vaginal bleeding?

Show the answer and rationale

Correct answer · Place an absorbent pad or sanitary dressing over the perineum and monitor vital signs

This patient has heavy vaginal bleeding after blunt trauma to the perineum, and the patient is stable. The blood pressure is 118/72, the pulse is 92, and the respirations are 16. Care for vaginal bleeding stays on the outside of the body. Place an absorbent pad or sanitary dressing over the perineum, and put nothing into the vagina. The pad soaks up the blood and lets you see how fast the patient is bleeding. Heavy bleeding can still lead to shock in a patient who looks stable now. Recheck the vital signs on the way to the hospital.

Why the others are wrong

Pack the vagina with sterile gauze to achieve hemostasis: Packing gauze into a wound is for a junctional site like the groin or armpit, where a tourniquet cannot reach. Vaginal bleeding is different. Packing the vagina means trying to control the bleeding from inside, and care for vaginal bleeding stays external, with pads and dressings only.

Irrigate the vaginal canal with sterile saline to flush clots: Irrigation flushes dirt and debris out of an open wound. Heavy bleeding needs the clots left alone. Saline pushed into the vaginal canal can wash out clots that are slowing the bleeding. Putting saline into the canal is also internal care, which vaginal bleeding does not get.

Apply direct pressure with a tourniquet above the groin to occlude blood flow: A tourniquet is for bleeding from an arm or a leg when direct pressure does not stop it. This bleeding is coming from the perineum, not from a limb. A band above the groin cannot close off the vessels that are bleeding here.

Question 8 of 10

A 17-year-old patient who is an athlete presents immediately after blunt trauma to the scrotum sustained during a contact sport. The patient reports severe localized pain and mild nausea but denies loss of consciousness or abdominal trauma. The primary assessment is unremarkable. Vital signs are normal: BP 132/78 mmHg, P 88/min, R 16/min. The scrotum is visibly swollen and ecchymotic. The patient is in obvious discomfort and guarding the area. What is the most appropriate prehospital management of this patient?

Show the answer and rationale

Correct answer · Position for comfort with scrotum elevated, apply cold pack, transport for evaluation

This patient has blunt trauma to the scrotum. The scrotum is swollen and bruised, and the patient is in severe pain and guarding the area. Let the patient get into the position that is most comfortable. Elevate the scrotum to bring down the swelling and the pain. Put a cold pack on the area to keep more swelling from building up. These steps are all supportive care. Finding out whether a testicle is damaged has to happen at the hospital, so transport the patient for that evaluation.

Why the others are wrong

Apply ice packs directly to the scrotum for 10 minutes, then transport supine: Cold on the scrotum is part of the right care. Forcing the patient to lie supine is the problem. The patient should stay in whatever position is most comfortable. A also leaves out elevating the scrotum, and elevation helps bring the swelling down.

Palpate both testes to assess for rupture before transport: Checking for a rupture is the hospital's job. Feeling the testes yourself adds pain and can cause more harm. What you find would not change how you treat this patient in the field.

Delay transport for 30 minutes to allow swelling to decrease before moving the patient: Waiting 30 minutes for the swelling to go down only delays care. The scrotum can hold a large amount of blood after a blunt injury. Only the hospital can tell how badly the testicles are hurt, so this patient needs timely evaluation there.

Question 9 of 10

A 35-year-old patient struck in the chest by an object has diminished breath sounds on the right side, with normal breath sounds on the left. Vital signs are stable: P 92/min, R 18/min, BP 132/88 mmHg. The patient's neck veins are normal, trachea is midline, and airway is patent. What is the most appropriate initial management by the EMT?

Show the answer and rationale

Correct answer · Give high-flow oxygen, position upright or semi-recumbent, and transport with monitoring

This patient has a simple pneumothorax. Breath sounds are diminished on the right and normal on the left. The blood pressure is 132/88, the pulse is 92, and the neck veins are normal. Those findings show no signs of a tension pneumothorax. There is air in the pleural space, but not enough pressure to shift the mediastinum or block blood returning to the heart. Breathing and circulation are holding up. Give high-flow oxygen and sit the patient upright or semi-recumbent to make breathing easier. Transport promptly and keep reassessing. Watch for distended neck veins, a falling blood pressure, or breath sounds that go from diminished to absent. Those signs mean the simple pneumothorax is turning into a tension pneumothorax.

Why the others are wrong

Administer high-flow oxygen and prepare equipment for needle decompression en route: Needle decompression is the treatment for a tension pneumothorax, and it is a paramedic skill. The signs of a tension pneumothorax are distended neck veins, tracheal deviation, and hypotension. This patient's vital signs, neck veins, and trachea are all normal, so there is nothing to get ready for. Needle decompression is also not something an EMT carries.

Assist ventilations with a BVM to help reexpand the collapsed portion of lung: Assisting ventilations with a BVM is for a patient who is breathing too slowly or too shallowly, or not at all. This patient has a respiratory rate of 18 and an open airway, which is adequate. Positive pressure can make a pneumothorax worse and speed up a tension pneumothorax.

Perform immediate needle decompression on the right side of the chest at the second intercostal space: Needle decompression at the second intercostal space treats a tension pneumothorax, the kind with distended neck veins, a deviated trachea, and hypotension. None of those are here, since the trachea is midline and the neck veins are normal. Needle decompression is a paramedic skill, so an EMT cannot perform it in any case.

Question 10 of 10

A 22-year-old cyclist struck by a motor vehicle across the anterior chest has high-impact blunt trauma. On assessment, the chest wall is intact with no flail segment, breath sounds are clear and equal bilaterally, but the patient coughs up blood-tinged sputum. Oxygen saturation is 88% on room air and declining. What is the most appropriate EMT action?

Show the answer and rationale

Correct answer · Give high-flow oxygen and monitor for progressive respiratory compromise during transport

This patient has a pulmonary contusion, which is a bruised lung. The chest wall is intact with no flail segment, so this is not a flail chest. The breath sounds are clear and equal, so a pneumothorax or hemothorax is unlikely. The patient is coughing up blood-tinged sputum, and the oxygen saturation is 88% and still dropping. Those two findings point to an injury inside the lung tissue itself. The blunt hit bruised the lung, and blood and fluid are leaking into the alveoli. Alveoli full of blood and fluid cannot move oxygen into the blood. That is why the saturation keeps drifting down instead of crashing all at once. You cannot fix the bruise in the field. Give high-flow oxygen so the alveoli that still work get as much oxygen as possible. Reassess often, because a contusion gets worse over time. This patient may need help breathing before you reach the hospital.

Why the others are wrong

Treat this as simple rib fractures and transport with routine monitoring of vital signs: This patient is coughing up blood, and a rib fracture by itself does not do that. The saturation is 88% and falling, which means the lung tissue is failing. Calling this simple rib fractures leaves the patient without high-flow oxygen and without close watching.

Apply an occlusive dressing to the entire chest wall to seal air leaks from the injury: This chest wall is intact and the injury is blunt, so there is no hole for an occlusive dressing to seal. Covering the whole chest also hides skin you need to keep checking and limits how much the chest wall can move, and this patient is already struggling to oxygenate.

Begin positive-pressure ventilations immediately to forcefully reexpand the injured lung: Forcing air into bruised, bleeding lung tissue can make the injury bigger and make the bleeding worse. This patient is still breathing without help, so start with high-flow oxygen and assist only if that breathing fails.
