Question 1 of 10

The paramedic arrives to find a patient with a single stab wound to the left upper abdomen. The patient is alert, denies severe pain, and vital signs are currently stable. Which assessment principle is most critical to guide the paramedic's care?

Show the answer and rationale

Correct answer · Penetrating trauma can injure deep structures despite a small wound, without visible shock

A stab wound can injure deep organs even when the wound is small and the patient shows no signs of shock. The size of the wound tells you how wide the blade was, not how far the blade went. The left upper abdomen sits over the spleen and the stomach, with the diaphragm just above. A wound there can reach the abdomen, the chest, or both. Bleeding into the abdomen is hidden. You see no blood and no swelling. A young patient makes up for the blood loss with a fast heart rate and tight blood vessels. The fast heart rate and tight vessels hold the blood pressure normal until a lot of blood is already gone. This patient denies severe pain, and the vital signs are stable right now. Those findings do not change the plan. Control any external bleeding, give oxygen as needed, and transport urgently. Reassess often so you catch the vital signs when they start to change.

Why the others are wrong

External bleeding is the most reliable indicator of how serious an abdominal stab wound is: External bleeding is a fair gauge of how bad a wound is when you can see the whole wound. An abrasion or a shallow cut is that kind of wound. You cannot see the depth of a stab wound. In penetrating abdominal trauma, the dangerous bleeding is inside the abdomen. A patient can lose a lot of blood into the abdomen while the dressing over the wound stays almost dry.

A small entry wound makes injury to deep organs such as the liver or spleen unlikely: A small entry wound tells you the blade was narrow. A narrow blade can still reach the spleen from the left upper abdomen. A small wound tells you about the weapon and nothing about the organs underneath.

Stable vital signs indicate that urgent transport is unnecessary for abdominal stab wounds: Stable vital signs carry real weight in a minor complaint with no penetrating injury. In penetrating trauma the vital signs lag behind the injury. The body holds the numbers steady while the bleeding continues. Transport priority for a stab wound comes from what the blade could have reached, and reassessment catches the change when the vital signs finally drop.

Question 2 of 10

A sedan collides head-on with a tree at highway speed. The driver is still in the vehicle; the steering wheel is severely bent and the dashboard is intruded into the passenger compartment. Based on this frontal-impact mechanism, which injury pattern is most likely?

Show the answer and rationale

Correct answer · Head and thoracic injury, including cardiac contusion

This driver most likely has head and chest injuries, including a cardiac contusion. In a frontal crash, the driver keeps moving forward until something stops him. Here the steering wheel is severely bent, and the dashboard is pushed into the passenger compartment. A bent steering wheel tells you the chest hit the wheel hard. That force causes rib and sternum fractures, a pneumothorax, and a cardiac contusion, which is a bruised heart muscle. The driver also goes up and over the wheel. The head hits the windshield or the wheel, and the impact injures the brain. Injuries to the head and chest are the ones that kill in the first minutes. Look for them first on this patient.

Why the others are wrong

Foot and leg fractures from pedal and floorboard contact: Foot and leg fractures from the pedals and floorboard are real frontal crash injuries. You look for them during the secondary exam. The damage in this car is at the steering wheel and the dashboard. Those parts of the car hit the chest and the head, not the feet. A broken ankle also does not kill in the first minutes, and a cardiac contusion or a pneumothorax can.

Facial trauma with mandibular fractures from airbag contact: Facial fractures do happen in a frontal crash when the head goes up and over into the windshield or the wheel. The same force that breaks the face keeps going into the brain behind it. The bent steering wheel also tells you the chest was hit. Calling this a face injury misses the cardiac contusion and the pneumothorax.

Lower abdominal and pelvic trauma from the seat belt: Lower abdominal and pelvic injuries fit a down-and-under path, where the driver slides down under the dashboard. They also fit a lap belt worn without a shoulder belt. Nothing in this question points there. The bent wheel and the pushed-in dashboard both hit the upper body. A head-on crash at highway speed with the dashboard pushed in is going to injure more than one body system.

Question 3 of 10

A 34-year-old patient is the restrained driver of a car struck on the driver's side door, causing 18 inches of intrusion into the passenger compartment at the door. The patient is alert and oriented, denies loss of consciousness, and complains only of hip pain. The patient's vital signs are within normal limits. Which of the following is the primary reason the paramedic should still treat this as a significant mechanism of injury?

Show the answer and rationale

Correct answer · Intrusion of ≥12 inches at the occupant site (or ≥18 inches elsewhere) is a significant-MOI criterion

The 18 inches of intrusion at the driver's door makes this a significant mechanism of injury. The significant MOI criterion is 12 inches of intrusion at the occupant site, or 18 inches anywhere else. This crash meets that criterion on its own. Intrusion pushes in toward the patient and sends force through the pelvis, chest, and abdomen. Solid organ and blood vessel injuries can be there before any pain or change in vital signs shows up. Handle this patient as high risk for hidden injury. Do a rapid trauma assessment, use spinal precautions as indicated, and transport to a trauma center. Do all of this even with normal vital signs and only hip pain.

Why the others are wrong

The patient's complaint of hip pain is what defines this as a significant mechanism of injury: Hip pain is a real finding, and pain in one spot often points you toward a specific injury. Pain does not define a significant mechanism. The amount of intrusion does. A patient with no complaints at all and the same 18 inches of intrusion still meets the criterion.

Normal vital signs at this point rule out a significant mechanism of injury: Normal vital signs often do mean a patient is less sick. Early on, the body can keep the vital signs normal for a while even with serious internal or blood vessel injury. A normal set this early does not rule anything out. The 18 inches of intrusion meets the criterion no matter what the vital signs are.

Only unrestrained occupants are classified under significant mechanism of injury criteria: Unrestrained occupants do have a higher risk of ejection and worse intrusion injuries. Restraint use is not part of the significant MOI criterion here. A restrained driver with 18 inches of door intrusion still meets the criterion.

Question 4 of 10

A 71-year-old patient with a 20-year history of insulin-dependent diabetes reports "just not feeling right" and mild nausea for the past hour. The patient denies chest discomfort. Which of the following statements about this presentation is most accurate?

Show the answer and rationale

Correct answer · Diabetic autonomic neuropathy can blunt pain perception, so a vague complaint should raise, not lower, suspicion for a cardiac cause

This patient could be having a silent myocardial infarction. The patient has had insulin-dependent diabetes for 20 years, says they are "just not feeling right," and has mild nausea with no chest discomfort. Long-standing diabetes damages the autonomic nerves that carry pain signals from the heart. A myocardial infarction can then show up without classic chest pain. A vague complaint in this patient should raise your suspicion for a cardiac cause, not lower it. Get a 12-lead ECG and watch for dysrhythmias. Transport with the same urgency as a patient who reports chest pain. Do not downgrade the call because the pain is missing.

Why the others are wrong

Nausea and vague malaise in a diabetic patient most likely signal impending hypoglycemia, not an evolving cardiac event: Hypoglycemia can cause sweating, weakness, and vague malaise in a patient on insulin. Checking a glucose is reasonable here. This patient is 71 with 20 years of diabetes, the group most likely to have silent ischemia. Nausea with no glucose reading does not point to hypoglycemia over an atypical cardiac event.

A vague, nonspecific complaint in a long-standing diabetic patient is most likely low-acuity and needs only reassurance: Reassurance alone is for a complaint that is truly low acuity. A 71-year-old with 20 years of insulin-dependent diabetes is the patient most likely to have a silent cardiac event. Reassurance skips the cardiac risk instead of ruling a cardiac cause out first.

Nausea without chest discomfort in a diabetic patient is most consistent with a gastrointestinal cause, not an evolving cardiac one: Nausea can come from a GI problem. In a diabetic with autonomic neuropathy, nausea is a known anginal equivalent, meaning nausea can show up in place of chest pain during ischemia. Blaming the GI tract before you rule out cardiac ischemia treats the wrong cause first.

Question 5 of 10

A 44-year-old patient reports 18 hours of steadily worsening abdominal pain. Which finding most strongly suggests peritoneal irritation?

Show the answer and rationale

Correct answer · Involuntary rigidity of the abdominal wall

Involuntary rigidity of the abdominal wall means peritoneal irritation, or peritonitis. The parietal peritoneum, the lining on the inside of the abdominal wall, is inflamed. The problem is no longer only in the organ underneath. The parietal peritoneum has nerves that map to the exact spot on the abdominal wall over the irritation. Irritation there makes the rectus and oblique muscles tighten by reflex. The patient cannot relax those muscles on purpose. Voluntary guarding is different, because the patient can relax voluntary guarding. Rigidity, along with rebound tenderness, tells you this is a surgical abdomen and not a medical one. Once you find rigidity, stop deep palpation. Keep the patient still and supine, and transport fast for surgical evaluation instead of repeating exams in the field.

Why the others are wrong

Constant restless movement to find relief: Restless movement to find relief comes from visceral pain. Hollow organs like the ureter or gallbladder send pain through nerves that do not point to one spot. Patients with kidney stone pain or gallbladder pain writhe around trying to get comfortable. Peritoneal irritation makes the patient lie still, because any movement stretches the inflamed peritoneum and hurts more.

High-pitched rushes heard over the abdomen: High-pitched rushes are hyperactive bowel sounds. Hyperactive bowel sounds happen early in a bowel obstruction, when the bowel squeezes harder against the blockage. Peritonitis gives you quiet or absent bowel sounds, because the inflamed bowel stops moving.

Burning discomfort relieved by an antacid: Burning pain relieved by an antacid fits a peptic ulcer or reflux. Acid irritates the lining of the stomach or esophagus, and neutralizing the acid brings quick relief. This patient's pain has steadily worsened for 18 hours. Peritoneal irritation does not get better with an antacid.

Question 6 of 10

A 70-year-old patient reports 2 days of black, tarry stools and near-fainting on standing this morning. The skin is pale, cool, and moist. Medications include metoprolol and lisinopril. The vital signs are BP 86/54, P 78, R 22, and SpO₂ 95% on room air. What most likely explains the pulse rate?

Show the answer and rationale

Correct answer · Beta blockade blunting the compensatory tachycardia

This patient has a GI bleed, and the metoprolol is keeping the pulse from going up. Black, tarry stools are digested blood, usually from the upper GI tract. The patient has lost enough blood to drop the blood pressure to 86/54 and to nearly faint on standing. The skin is pale, cool, and moist. A patient who has lost this much blood should be tachycardic. This patient's pulse is 78. Metoprolol is a beta blocker. Beta blockers block the sympathetic signal at the SA node, so the heart rate stays normal while the patient bleeds. In a patient on a beta blocker, a normal pulse never rules out shock.

Why the others are wrong

Preserved perfusion that has not yet triggered tachycardia: Perfusion is not preserved here. The patient nearly fainted on standing, is pale, and is sweating. Those findings show perfusion is already poor. The pulse looks normal because the beta blocker is hiding the tachycardia.

Increased vagal tone from repeated straining at stool: Straining at stool can raise vagal tone and slow the heart. This patient has 2 days of black, tarry stools and pale, cool, moist skin. Those findings point to blood loss, not a vagal event.

Long-standing anemia with an adapted resting rate: Long-standing anemia can let the body settle into a different resting rate over time. Near-fainting this morning with ongoing GI bleeding is a sudden problem, not a slow adjustment.

Question 7 of 10

A 26-year-old patient reports sudden lower abdominal pain that began 1 hour ago, along with left shoulder pain that worsens when lying flat. The last menstrual period was about 7 weeks ago. The skin is pale and moist. The vital signs are BP 88/56, P 124, and R 24. What best explains the shoulder pain?

Show the answer and rationale

Correct answer · Blood in the peritoneal cavity irritating the diaphragm

This patient most likely has a ruptured ectopic pregnancy that is bleeding into the abdomen. The last menstrual period was about 7 weeks ago. The lower abdominal pain started suddenly 1 hour ago. The blood pressure is 88/56, the pulse is 124, and the skin is pale and moist. The free blood spreads through the peritoneal cavity. When the patient lies flat, the blood pools up against the diaphragm. The phrenic nerve supplies the diaphragm. The phrenic nerve comes from the same levels of the spinal cord in the neck that supply the skin over the shoulder. That's why blood under the diaphragm is felt as shoulder pain, and why the shoulder pain gets worse lying flat. In a patient with abdominal pain, shoulder pain like this is a sign of bleeding, not a muscle or joint problem.

Why the others are wrong

Distention of the fallopian tube stretching the pelvis: A stretched fallopian tube would cause pain in the pelvis. Pelvic stretching does not send pain to the shoulder, and it does not explain why lying flat makes the shoulder worse.

Ureteral spasm referred along the flank and shoulder: Ureteral spasm sends pain along the flank and into the groin. Ureteral spasm does not reach the shoulder, and it does not explain a missed period with signs of shock.

Cardiac ischemia referred to the left arm and shoulder: Cardiac ischemia can send pain to the left arm and shoulder, usually along with chest symptoms. Cardiac ischemia is not tied to body position the way this shoulder pain is. Cardiac ischemia also does not explain the abdominal pain or the low blood pressure.

Question 8 of 10

The paramedic forms a hands-off general impression of a 2-year-old patient from the doorway using the pediatric assessment triangle. Which finding belongs to the work of breathing component?

Show the answer and rationale

Correct answer · Nasal flaring

Nasal flaring is a work of breathing finding. Nasal flaring is the nostrils widening as the toddler tries to lower airway resistance and pull more air into the lungs. Flaring is a reflex to low oxygen or to harder work of breathing. The work of breathing side of the pediatric assessment triangle also includes retractions, grunting, stridor, and abnormal positioning. You can see every one of these from the doorway without touching the child. Seeing nasal flaring from the doorway tells you to move toward airway and oxygen treatment before you lay hands on the child. Nasal flaring also helps you sort out whether the problem is only respiratory or respiratory and circulatory together.

Why the others are wrong

Mottled skin color: Cyanosis and pallor often show up when a child is in respiratory failure, so skin color can seem tied to breathing. The triangle puts pallor, mottling, and cyanosis on the circulation to skin side, whatever the cause. The circulation side tells you about perfusion, not how hard the child is breathing.

Delayed capillary refill: a real sign of poor perfusion. Capillary refill is not part of the triangle at all. Checking capillary refill means pressing on the skin and timing the color return. Pressing on the skin breaks the hands-off, doorway-only rule of the general impression. Capillary refill belongs in the primary assessment once you reach the child.

Failure to focus on a caregiver: falls on the appearance side, which covers tone, interactiveness, and gaze. Appearance findings tell you whether the brain is getting enough blood and oxygen. Appearance does not tell you how hard the chest is working to move air.

Question 9 of 10

A 37-year-old patient is found unresponsive in a barn beside an overturned pesticide sprayer, with the clothing soaked. The pupils are 1 mm, the mouth is filled with secretions, and wheezing is heard in both lungs. The vital signs are BP 96/60, P 44, and R 8. The blood glucose level is 104 mg/dL. The paramedic treated the presentation as opioid poisoning, removed the clothing, and administered naloxone, and there has been no change in the breathing or the level of consciousness. What should the paramedic administer next?

Show the answer and rationale

Correct answer · Intravenous atropine

This patient has organophosphate poisoning from the pesticide. The patient was found next to an overturned pesticide sprayer with soaked clothing. The pupils are 1 mm, the mouth is full of secretions, and both lungs are wheezing. The pulse is 44, the blood pressure is 96/60, and the respirations are 8. Organophosphates block acetylcholinesterase, the enzyme that breaks down acetylcholine. Acetylcholine builds up and floods the muscarinic receptors. The extra acetylcholine causes the secretions, the bronchoconstriction, and the slow heart rate. Naloxone did nothing, so this is not an opioid overdose. Atropine blocks the muscarinic receptors. Blocking those receptors dries the secretions and improves the heart rate and the bronchospasm. Keep giving atropine until the secretions are under control, not to a set amount.

Why the others are wrong

A second dose of naloxone: fits an opioid overdose that needs more drug to reverse. Here the first dose did not change the breathing or the level of consciousness. The soaked clothing, pinpoint pupils, secretions, and wheezing point to the pesticide, not an opioid. Giving more of a drug that already failed treats the wrong cause.

Nebulized albuterol: Albuterol opens the airways, and both lungs are wheezing. Albuterol only treats the bronchospasm, and it does nothing for the secretions, the slow pulse, or the low blood pressure. Atropine dries the secretions, raises the heart rate, and treats the bronchospasm too.

Intravenous dextrose: Dextrose is for low blood sugar, and low blood sugar can cause an altered level of consciousness. This patient's blood glucose is 104 mg/dL, which is normal. Dextrose will not fix the pinpoint pupils, the secretions, or the slow heart rate.

Question 10 of 10

A 19-year-old college student has had fever and severe headache for 12 hours and is now confused and answering questions incorrectly. The patient resists flexion of the neck. A widespread purple rash is present over the trunk and legs and does not fade when pressed. The vital signs are BP 88/52, P 128, R 24, T 103.1°F, and SpO₂ 96% on room air. Which of the following is the most appropriate field impression?

Show the answer and rationale

Correct answer · Meningococcal sepsis

This patient has meningococcal sepsis. Fever, a stiff neck, and confusion together point to bacterial meningitis. A widespread purple rash that does not fade when you press on it is bleeding into the skin. Meningococcal infection injures the small blood vessels and uses up clotting factors, and that causes the rash. A purple rash that does not fade is the classic sign of meningococcal infection. The blood pressure is 88/52 and the pulse is 128, so the infection has already moved into septic shock. Use droplet precautions for the crew. Notify the hospital early so antibiotics are not delayed, and treat the shock during transport. These patients can get worse within hours.

Why the others are wrong

Viral meningitis: causes fever, headache, and a stiff neck too. A purple rash that does not fade when pressed comes with the bacterial form, and meningococcal infection is the classic cause. This patient has that rash, and the blood pressure of 88/52 with a pulse of 128 shows septic shock.

Subarachnoid hemorrhage: A subarachnoid hemorrhage causes a sudden headache that is at its worst right away. Blood irritating the lining of the brain can cause a stiff neck. A subarachnoid hemorrhage does not cause 12 hours of fever, a purple rash, or a temperature of 103.1°F. This illness came on gradually with a fever, which points away from a bleed.

Influenza with dehydration: Influenza can cause fever, headache, a fast pulse, and enough dehydration to drop the blood pressure. Influenza does not cause a stiff neck or a purple rash that does not fade when pressed. Those two findings move this patient out of a viral illness with dehydration.
