10 free Paramedic practice questions: Advanced Trauma Procedures

Along the inferior margin of the rib above, following the bundle: The inferior margin of the rib above is where the bundle sits, so following it is the one landmark to avoid. Naming the bundle does not make it a target.

Through the center of the interspace at a 45 degree angle: Angling the needle lengthens the path through the chest wall and invites skiving off a rib. Perpendicular entry is what reaches the pleural space reliably.

Under the inferior border of the rib above the interspace: Hugging the rib above puts the needle straight into the neurovascular bundle. That groove is where the vessels and the nerve live, and it bleeds.

The right distal tibia, since it sits away from the femur fracture: Moving to the uninjured leg still leaves the needle below an unstable pelvic ring, and the disrupted pelvic venous return is the problem. Both lower extremities are out for this patient.

The sternum, since the pelvis and both legs are involved: Sternal access belongs to specialized devices rather than standard Paramedic practice. The three taught sites are the proximal tibia, the distal tibia, and the proximal humerus.

The left proximal tibia, which is the most familiar landmark: The left leg sits distal to both the unstable pelvis and the femur fracture, so anything infused there drains into a disrupted venous return. Familiarity is not a reason to choose a site that will not deliver.

Apply a tourniquet as high on the thigh as it will physically reach: A tourniquet needs a limb between the device and the bleeding vessel. A groin wound sits above that, so the device cannot compress the artery feeding it.

Place a pelvic binder to compress the bleeding vessels: A binder addresses an unstable pelvic ring and the bleeding that comes with it. It does not compress a stab tract through the soft tissue of the groin.

Apply a pressure dressing and elevate the affected leg: A pressure dressing has already been outmatched, and elevation does not control arterial bleeding. This wound needs the cavity packed rather than covered.

Perform a surgical cricothyrotomy now, since two intubation attempts failed: Failed intubation alone is not a failed airway. Both halves have to fail, and ventilation is working, so cutting the neck adds bleeding and false passage risk for no gain.

Insert a second supraglottic airway of a smaller size: The supraglottic device already failed to seat in this anatomy, and a smaller one is unlikely to change that. The working technique is the one already in hand.

Make a third intubation attempt using a different blade: Repeat attempts on a face this disrupted risk converting a working situation into a lost one. A patient who is being oxygenated does not need another look right now.

It lowers the blood pressure in patients who have lost blood: Nitrous oxide has minimal effect on blood pressure compared with opioids. The contraindication here is about trapped gas rather than about volume status.

It depresses the respiratory drive in patients with rib fractures: Nitrous oxide is self administered and the mask falls away as sedation deepens, which limits respiratory depression. The problem in this patient is gas expansion inside the chest.

It is only approved for patients with isolated extremity injuries: The restriction is tied to a possible pneumothorax rather than to an injury category. Plenty of falls carry no chest injury at all.

Insert an endotracheal tube and ventilate: Intubation is the answer when the problem is a failure to ventilate or to protect the airway, and it is frequently part of the overall care of a critical chest trauma patient. It does nothing about air trapped under pressure in the pleural space, and positive pressure ventilation forces more air through the one-way leak, so intubating before decompressing can turn a critical patient into an arrested one. The key removes the pressure that is stopping venous return, while the tube raises it.

Apply CPAP: CPAP treats alveolar problems where positive pressure recruits collapsed lung or drives edema fluid back, as in pulmonary edema and some asthma and COPD presentations, all of them medical. Applied here it is more positive pressure feeding the tension, and it is contraindicated both in suspected pneumothorax and in a hypotensive patient. The key relieves pressure, while this adds to it.

Confirm tracheal deviation before intervening: Waiting to confirm tracheal deviation is the most dangerous option of the four, because it ties treatment to a sign that appears late, is difficult to appreciate in the field, and is absent in many confirmed tension pneumothoraces. This patient already shows the findings that matter: unilateral absent breath sounds, distended neck veins, and profound hypotension. The key acts on that triad, and delaying for a late sign costs exactly the minutes that decide the outcome.

Apply a pelvic binder at the iliac crests: The iliac crests are where most people instinctively place a binder, because the crests are the part of the pelvis you can actually feel, and that is exactly what makes this the strongest distractor. Compression there squeezes the iliac wings above the level of the ring, so pelvic volume barely changes and the tamponade never happens. Same device, same patient, wrong level, and the bleeding continues; the trochanters are the landmark because of the femoral head beneath them, not because they are easy to palpate.

Repeatedly assess pelvic stability by springing: Springing the pelvis to assess stability has already done its job, since one gentle palpation established instability and the question says so. Repeating it disrupts whatever clot has formed and can restart or worsen the bleeding, which is why pelvic stability is assessed once and only once. The key acts on information already obtained rather than re-collecting it at the patient's expense.

Log roll the patient to inspect the lower back: Log rolling to inspect the back is a standard part of a trauma assessment, but not in a patient with a known unstable pelvis and hypotension. Rolling shears the disrupted ring and the fragile clot forming around it. If the back has to be examined, it is done after the binder is on and with minimal movement, which is another way of saying the binder comes first.

Blind clamping of the bleeding vessel: Blind clamping belongs to an operating room with exposure and lighting, and even there vessels are clamped under direct vision. A clamp pushed into a bleeding neck wound in the field is as likely to catch the carotid artery, the vagus nerve, or the jugular vein as the bleeding vessel. That can convert a controllable venous bleed into an arterial or neurologic catastrophe, while the key controls the same bleeding with a technique that cannot injure what it cannot see.

A circumferential pressure dressing around the neck: A circumferential dressing sounds like a reasonable way to hold pressure, and on a limb it would be exactly right. On a neck it wraps a structure containing the trachea and both carotid arteries, so tightening it enough to stop bleeding also compresses the airway and the cerebral blood supply. That is precisely why neck bleeding is controlled with one-sided pressure and never a wrap.

A tourniquet placed above the wound: A tourniquet requires a site where a band can compress everything distal to it without cutting off something the patient needs, meaning an arm or a leg. The neck offers no such site, and a constricting band above a neck wound is a strangulation. Tourniquets are also an arterial-hemorrhage tool, and this bleeding is dark and steady, which is venous, so the key matches both the anatomy and the vessel that is actually bleeding.

Decompress the left chest with a needle: Needle decompression is right for tension pneumothorax, and a wound at the base of the neck can certainly injure the apex of the lung, so it belongs on the differential. All three findings that would support it are explicitly absent: breath sounds are clear and equal, the trachea is midline, and the chest wall is stable. Both conditions are obstructive, meaning something is blocking flow through the chest rather than the pump or the volume failing, but tension obstructs with a one-sided air collection while this obstructs with air inside the heart. Needling a normal chest creates the injury you were treating.

Elevate the head of the stretcher to 45 degrees: Elevating the head is right for pulmonary edema or respiratory distress in a patient with pressure to spare, where sitting up unloads the chest and eases the work of breathing. Here it does exactly the wrong thing: raising the head lifts the wound further above the heart, drops the pressure inside those neck veins further below atmospheric, and pulls more air in with every inspiration. This option deepens the mechanism while the key reverses it.

Infuse a rapid crystalloid bolus: A crystalloid bolus is the reflex for a pressure of 82/54 with a pulse of 130 after trauma, and volume is not wrong as an adjunct once the cause is addressed. This hypotension is obstructive rather than hypovolemic, because the right ventricle is filling and simply cannot push air-froth forward into the pulmonary artery. Fluid does not clear an air lock. Sealing the wound stops more air from entering and left-side-down with the head lowered moves what is already there away from the outflow tract, which is what actually restores forward flow.

Apply a vest-type extrication device first: A vest-type device is the standard choice for a seated patient with a possible spinal injury and stable vital signs, which is what makes it tempting. Applying one costs several minutes that a patient in decompensated hemorrhagic shock does not have, and no amount of spinal protection helps a patient who bleeds out before reaching surgery.

Wait for the rescue company to remove the roof: Removing the roof is reserved for patients who cannot be reached or removed through the openings that already exist. Both doors on the patient's side open normally, so the additional time buys no access the crew does not already have.

Allow the patient to step out unassisted: Self-extrication is used for patients who are alert and oriented with no neurologic complaint and no distracting injury. This patient answers slowly and is in shock, so cooperation cannot be relied on, and standing an actively bleeding patient upright invites a collapse in the doorway.
