1. Question 1

   An unresponsive patient with a suspected opioid overdose has a fentanyl patch on the upper chest, and the AEMT decides to remove it. Which technique protects the AEMT from absorbing the drug?

   • Grasp the patch by its edge with gloved fingers, peel it away, and wipe residual medication from the skin with gauze without touching the medicated surfaceCorrect
   • Pinch the center of the patch between the fingers so it folds onto itself and can be discarded quickly
   • Cut the patch in half with trauma shears before peeling it off the skin
   • Leave the patch in place, because a patch releases medication too slowly to matter during resuscitation

   Why: Transdermal medications are absorbed through skin, including the provider's, so the patch is grasped at its edge, peeled away without contacting the medicated surface even while gloved, and any residue is wiped from the patient with gauze. Pinching the center puts the fingers directly on the drug reservoir. Cutting a patch can release a large amount of concentrated medication and is unsafe. A fentanyl patch continually releases opioid and can complicate resuscitation, which is why removal is considered rather than leaving it in place.

2. Question 2

   A 68-year-old woman who had hip replacement surgery 4 days ago suddenly develops severe pleuritic chest pain and dyspnea while sitting in a chair. Her SpO2 is 89%, and her heart rate is 128/min. Two minutes later she becomes unresponsive and pulseless. What should guide your management?

   • Withhold CPR because her arrest was caused by a clot rather than a primary cardiac problem, and CPR would not help.
   • Recognize this presentation as consistent with a massive pulmonary embolism; begin CPR and manage this cardiac arrest per standard protocol, since the most severe cases of pulmonary embolism are treated as a cardiac arrest of unknown origin.Correct
   • This is most likely a vasovagal event; simply reposition her and reassess in a few minutes before considering CPR.
   • Because the cause is presumed to be a pulmonary embolism, transport emergently without initiating any resuscitation, since only fibrinolytics at the hospital can help.

   Why: Recent surgery and immobility are major risk factors for venous thromboembolism, and sudden pleuritic chest pain with dyspnea and hypoxia in this setting should raise strong suspicion for pulmonary embolism. When a suspected PE patient becomes pulseless and apneic, the correct approach is to initiate CPR and manage the arrest per standard protocol, because the most severe cases of pulmonary embolism are managed as a cardiac arrest of unknown origin in the field; there is no prehospital PE-specific treatment (such as fibrinolytics) available to substitute for basic and advanced life support. Withholding CPR because the presumed cause is embolic rather than primary cardiac is wrong and would deny indicated resuscitation to a patient in cardiac arrest regardless of etiology. This presentation, with objective hypoxia and tachycardia culminating in cardiac arrest, is not consistent with a self-limited vasovagal event. Delaying CPR to instead prioritize transport ignores that basic resuscitation must begin immediately in any cardiac arrest, regardless of what hospital-only treatments may exist.

3. Question 3

   An AEMT responds to a patient in cardiac arrest. The family presents a document they say is a DNR order, but it has no physician signature and does not clearly state the patient's underlying medical condition. What should the AEMT do?

   • Honor the document as presented, since any family-provided paperwork constitutes a valid DNR
   • Begin resuscitation and contact medical control for guidance, since the document does not meet the requirements for a valid DNRCorrect
   • Refuse to treat the patient at all until a physician arrives on scene
   • Ask the family to verbally confirm the patient's wishes and treat that confirmation as equivalent to a valid written DNR

   Why: A valid DNR order generally must clearly state the patient's medical condition and carry the signatures of the patient or guardian and one or more physicians (or other licensed providers); when presented paperwork does not meet these requirements, the correct action is to begin basic life support and contact medical control for direction. Choice A improperly accepts a document that does not meet the stated legal requirements. Choice C abandons a patient in cardiac arrest instead of initiating clearly indicated care, which is not supported by doubts about a DNR's validity. Choice D substitutes an informal verbal assurance for the written, physician-signed documentation the DNR framework requires.

4. Question 4

   What is the primary cause of a dissecting aortic aneurysm?

   • Uncontrolled hypertensionCorrect
   • Bacterial infection of the heart valves
   • Coronary artery atherosclerosis
   • Long-standing low blood pressure

   Why: Chronically uncontrolled high pressure inside the aorta is the main force that tears the inner layers apart and lets blood track between them, which is why the AEMT should consider dissection in any chest pain patient with marked hypertension. Bacterial endocarditis damages valves and can seed emboli but is not the usual cause of dissection. Coronary atherosclerosis narrows the heart's own arteries and causes ischemia, a different disease process. Low blood pressure does not stress the aortic wall and would not produce a dissection.

Cross-reference: Pathophysiology: A Practical Approach, Fifth Edition, paras 801-840.

5. Question 5

   A 26-year-old man was partially ejected during a rollover crash. At the scene, he is alert, ambulatory, and reports only minor scrapes, with a blood pressure of 122/78 mm Hg and a heart rate of 92/min. He insists he feels fine and wants to refuse transport. Fifteen minutes later, while you continue to assess him, his heart rate rises to 128/min with no change in his blood pressure. What should guide your decision-making?

   • Because his blood pressure remains normal, he is hemodynamically stable, and his desire to refuse transport should be honored without further concern.
   • Since he is ambulatory and talking normally, occult injury is very unlikely, and further monitoring is unnecessary.
   • The rising heart rate is most likely just anxiety about the crash and does not require any change in your assessment or recommendations.
   • The significant mechanism of injury (ejection) combined with his new, otherwise-unexplained tachycardia should raise a high index of suspicion for occult injury and compensated shock; strongly recommend transport and continued aggressive reassessment.Correct

   Why: Ejection from a vehicle is a significant mechanism of injury that should raise the AEMT's index of suspicion for serious, potentially occult injuries even when the patient looks well initially. Because patients with compensated shock may not manifest hypotension until severe blood loss has already occurred, a new, unexplained rise in heart rate — even with a normal blood pressure — is an important early warning sign that should not be dismissed, especially given this mechanism. The correct approach is to maintain a high index of suspicion, continue serial reassessment, and strongly recommend transport rather than accepting a refusal based on a reassuring blood pressure alone. Relying on blood pressure as the sole marker of stability ignores that tachycardia is often the first, and for a time the only, sign of compensated shock. A mechanism this significant, combined with a new trend in vital signs, specifically argues against relaxing suspicion just because the patient is currently ambulatory and conversant. Attributing the tachycardia to anxiety substitutes an unverified assumption for a documented, objective vital sign change in a high-risk mechanism, which is not a safe way to rule out shock.

7. Question 6

   A 15-year-old boy suddenly develops severe left testicular pain and swelling while playing basketball, with no history of trauma. He is in obvious distress. Which statement about the appropriate AEMT management is correct?

   • This is a surgical emergency; the priority is prompt, gentle transport in a position of comfort, not field diagnosis or correctionCorrect
   • The AEMT should attempt to manually untwist the testicle before transport
   • Transport can be delayed until the patient's pain is fully controlled with oral medication
   • This condition typically resolves on its own within a few hours and requires only reassurance

   Why: Testicular torsion twists the spermatic cord and its blood vessels, cutting off the testis's blood supply, so the window for surgical correction to save the testis is limited, making this a time-sensitive surgical emergency rather than something to be diagnosed or corrected in the field. AEMTs should transport the patient promptly in whatever position is most comfortable rather than attempting manual detorsion, which is outside the AEMT scope and could worsen the injury. Delaying transport for oral pain control ignores the urgency of restoring blood flow, and this condition does not resolve on its own without treatment — delayed care can result in permanent loss of the testis.

8. Question 7

   A 19-year-old skateboarder falls and strikes his temple on the curb. Bystanders say he was knocked out immediately, then got up, seemed confused but coherent, and was talking normally for several minutes. By the time you arrive about 15 minutes after the fall, he is unresponsive, and his right pupil is now fixed and dilated. What does this pattern most likely represent, and what should guide your care?

   • This lucid interval followed by rapid deterioration and a newly fixed, dilated pupil is classic for an epidural hematoma; treat this as a time-critical neurosurgical emergency with airway management, oxygenation, and immediate rapid transport to a trauma center.Correct
   • Because he was awake and talking normally after the fall, his brain injury is likely minor, and the new unresponsiveness is probably an unrelated cause such as fatigue.
   • This pattern is typical of a simple concussion, and he should be allowed to rest without further intervention until he wakes up on his own.
   • The fixed, dilated pupil is most likely a preexisting anatomic variant unrelated to his fall and does not require any change in transport priority.

   Why: An epidural hematoma classically results from a temporal bone fracture that tears the middle meningeal artery, producing rapidly accumulating arterial bleeding between the skull and the dura. The classic presentation is a patient who becomes unresponsive immediately after the injury, experiences a brief lucid interval during which he appears aware and coherent, and then lapses back into unresponsiveness as intracranial pressure rises; a fixed, dilated pupil on the side of the hematoma develops as pressure increases, and death can follow rapidly without prompt surgical evacuation. This time course means the lucid interval is not reassuring — it precedes a life-threatening decline — so the AEMT must treat this rapid deterioration as a true emergency, not a minor injury. Treating the lucid interval as evidence of a minor injury or an unrelated cause misses the classic, well-established time course of this specific injury. Simple concussion does not produce a subsequently fixed, dilated pupil or progressive unresponsiveness, so it does not fit this pattern. Dismissing the pupil finding as an unrelated variant ignores its clear temporal relationship to the head injury and the observed lucid interval.

Cross-reference: Pathophysiology: A Practical Approach, Fifth Edition, Neural Function, paras 481-520.

9. Question 8

   A woman at 34 weeks gestation calls EMS for vaginal bleeding. On exam she has bright red blood, denies abdominal pain, and her uterus is soft and nontender on gentle palpation. Which condition is most consistent with these findings?

   • Placenta previa
   • Abruptio placentaeCorrect
   • Ectopic pregnancy
   • Spontaneous abortion

   Why: Placenta previa classically produces painless, bright red vaginal bleeding with a soft, nontender uterus, because the bleeding originates from a placenta implanted over the cervix rather than from uterine muscle injury. Abruptio placentae, by contrast, causes sudden abdominal pain and a tender, often rigid uterus, with darker blood that may even be partially concealed. Ectopic pregnancy occurs in the first trimester, not the third, and spontaneous abortion is a first- or second-trimester event, so neither fits a 34-week presentation.

Cross-reference: National Model EMS Clinical Guidelines, Version 3.0, March 2022, Obstetrical and Gynecological Conditions, p. 175.

10. Question 9

    While assessing a patient with pneumonia, the AEMT wants to identify hypoxia before it becomes severe. Which finding is most consistent with an early stage of hypoxia?

    • Cyanosis of the lips and nail beds
    • A weak, thready pulse
    • Restlessness with tachycardiaCorrect
    • Unresponsiveness to verbal stimuli

    Why: The earliest signs of hypoxia are subtle changes driven by the sympathetic response and an irritable brain: restlessness, irritability, apprehension, anxiety, and a fast heart rate. Recognizing these allows oxygen to be given before deterioration. Cyanosis, a weak or thready pulse, and altered mental status such as unresponsiveness are late findings that indicate the patient has already decompensated, so waiting for them delays treatment.

Cross-reference: Pathophysiology: A Practical Approach, Fifth Edition, paras 241-280.

11. Question 10

    Lightning strikes a group of five hikers. Two are alert and walking around, complaining of tingling and confusion; two are conscious but in obvious pain from burns; and one is in cardiac arrest. Only one EMS crew is on scene, with additional units several minutes out. Following recognized guidance for multiple lightning-strike victims, whom should the crew treat first?

    • The two hikers with burns, because visible injuries should always be triaged before less obvious complaints in a multiple-casualty incident.
    • The patient in cardiac arrest, because lightning-strike triage is 'reverse' from conventional mass-casualty triage: those in respiratory or cardiac arrest are prioritized first, since alert survivors are unlikely to deteriorate further while patients in arrest have a comparatively good chance of successful resuscitation.Correct
    • The two alert, confused hikers, because altered mental status always takes priority over cardiac arrest in any multiple-casualty incident.
    • Whichever patient is closest to the ambulance, since triage order does not matter as long as everyone is treated within the same few minutes.

    Why: In a lightning strike, respiratory or cardiac arrest usually occurs immediately if it is going to occur, and those who remain alert are much less likely to develop delayed arrest and are likely to survive; because of this, the recognized approach is reverse triage, which focuses efforts on those in respiratory or cardiac arrest rather than classifying them as deceased the way conventional MCI triage would. This differs from standard mass-casualty triage specifically because of how good the odds of successful resuscitation are after a lightning injury. Choice A is wrong because it applies conventional triage logic (visible injury over occult risk) that is explicitly reversed in lightning-strike incidents. Choice C is wrong because alert, ambulatory patients are lower priority in this specific scenario, not higher, since they are unlikely to deteriorate further. Choice D is wrong because deliberate reverse triage, not proximity, is the recognized approach to prioritizing care among multiple lightning victims.

12. Question 11

    An AEMT is preparing to apply AED pads to a pulseless, apneic 66-year-old man and notices a firm lump with an overlying scar just below the left clavicle, consistent with an implanted cardioverter-defibrillator. How should the AED pads be positioned?

    • Directly over the device so the shock is conducted through it to the heart
    • At least 1 inch (2.5 cm) away from the edge of the implanted deviceCorrect
    • Both pads on the patient's back, because anterior placement is contraindicated with implanted devices
    • Do not apply the AED; the implanted device will manage any shockable rhythm

    Why: An implanted defibrillator or pacemaker sits under the skin of the upper chest and can block part of the AED's current, or be damaged by it, if a pad lies directly on top of it, so the pad is kept at least 1 inch (2.5 cm) from the device while the AED is otherwise used normally. Placing the pad over the device (choice A) reduces shock effectiveness and risks damaging the implant. There is no requirement for posterior-only placement (choice C); the usual right-upper-sternum and left-lower-chest positions are typically already more than an inch from a device under the left clavicle. Withholding the AED (choice D) is wrong because an implanted device may have failed or exhausted its therapy, and the patient is in confirmed cardiac arrest.

13. Question 12

    An AEMT is assisting a patient who was stung by a honeybee and whose stinger is still embedded in the skin. What is the correct way to remove the stinger?

    • Grasp it firmly with tweezers and pull it straight out
    • Scrape it away using the edge of a stiff, flat item like a plastic cardCorrect
    • Squeeze the skin around it to pop the stinger free
    • Leave it in place and apply a tourniquet proximal to the site

    Why: A honeybee's barbed stinger remains embedded with its venom sac attached and can continue injecting venom for up to 20 minutes. Scraping it out with the edge of a stiff, flat object such as a credit card removes the stinger without compressing the venom sac. Using tweezers or forceps, or otherwise squeezing the area, presses on the venom sac and pushes additional venom into the wound, which is the opposite of what is intended. A tourniquet is not indicated for an insect sting and would not address the embedded stinger at all. Primary reference: Advanced Emergency Care and Transportation of the Sick and Injured (Hunt, AAOS/Jones & Bartlett Learning, 4th Edition), Immunologic Emergencies, p. 1155.

14. Question 13

    Twenty minutes after an AEMT applied a tourniquet that stopped arterial bleeding from a patient's lower leg, the patient begs for it to be loosened because of severe pain. Fifteen minutes of transport remain. What should the AEMT do?

    • Leave the tourniquet tight, manage the pain according to protocol, and notify the receiving facility that a tourniquet is in placeCorrect
    • Loosen it briefly every 10 to 15 minutes to allow some blood flow to the limb
    • Remove it and substitute a pressure dressing, because the bleeding has stopped
    • Loosen it slightly for comfort while leaving it in position

    Why: Once a tourniquet has controlled life-threatening bleeding it is not loosened or released in the field; release is deferred to the hospital team, which can deal with the bleeding surgically, and even a brief release can allow rapid, uncontrolled rebleeding. A properly applied tourniquet is painful, and the correct response is analgesia per protocol, not loosening. Substituting a pressure dressing after arterial bleeding has already defeated direct pressure invites exsanguination. Partial loosening is the worst option because it may permit arterial inflow while still obstructing venous return.

Cross-reference: National Model EMS Clinical Guidelines, Version 3.0, March 2022, PDF p. 226.

15. Question 14

    EMS personnel have applied physical restraints to a violent patient with medical control authorization. Which action is correct once the restraints are in place?

    • Position the patient prone (face-down) to make monitoring easier for the crew
    • Remove the restraints en route if the patient promises to remain calm
    • Keep the patient in a position other than prone, and continuously monitor for breathing difficultyCorrect
    • Place a surgical mask over the patient's face to prevent spitting, regardless of position

    Why: Once restraints are applied, they must not be removed en route even if the patient promises to behave, the patient must never be placed prone because of the risk of positional asphyxia, and the crew must continuously watch for signs of breathing difficulty. Choice A creates a suffocation risk and is exactly the position to avoid. Choice B is wrong because restraints, once applied, should not be removed during transport based on a patient's assurances. Choice D risks blocking airflow if the mask obstructs the airway, which is especially dangerous combined with any restrained position. Primary reference: Advanced Emergency Care and Transportation of the Sick and Injured (Hunt, AAOS/Jones & Bartlett Learning, 4th Edition), Medical, Legal, and Ethical Issues, p. 130. Cross-reference: National Model EMS Clinical Guidelines, Version 3.0, March 2022, PDF p. 63 — the Agitated or Violent Patient/Behavioral Emergency Guideline expressly prohibits "secure or transport in a prone position with or without hands and feet behind the back (hobbling or ‘hog-tying’)" and "techniques that constrict the neck or compromise the airway."

16. Question 15

    A construction worker is pinned under a fallen concrete slab that compresses his chest for several minutes before rescuers can lift it. Just before extrication, his face and upper neck appear deeply cyanotic with distended neck veins, and his eyes appear to bulge slightly. Once the slab is lifted and he is extricated, his blood pressure suddenly drops. What does this sequence represent, and what should you anticipate?

    • This is an allergic reaction to dust exposure; treat with epinephrine and antihistamines.
    • The facial cyanosis and eye bulging are simply artifacts of positioning and will resolve without any specific concern once he is moved.
    • Because his color was concerning only before extrication, no further shock precautions are needed now that the compression has been relieved.
    • This is traumatic asphyxia from sudden, severe compression of the chest; anticipate hypotension upon release of the compressing force and be prepared to treat for shock with IV access and rapid transport to a trauma center.Correct

    Why: A sudden, severe increase in intrathoracic pressure from chest compression produces the characteristic appearance of traumatic asphyxia: distended neck veins, cyanosis of the face and upper neck, and sometimes bulging eyes (exophthalmos) from the backward transmission of pressure into the venous system above the compression. A key feature of this injury is that hypotension characteristically occurs when the compressing pressure is released, so the AEMT should anticipate this and be prepared with IV access, fluid resuscitation, and rapid transport to a trauma center rather than being falsely reassured once the patient is extricated. This presentation, with a clear compressive mechanism and classic exam findings, is not an allergic reaction, and epinephrine/antihistamines would not address the actual injury. The facial cyanosis and eye findings are direct effects of the compression mechanism, not positional artifacts, and dismissing them would miss the anticipated post-release hypotension. Because hypotension is expected specifically after release of the compression, this is exactly the moment the AEMT must be most vigilant for shock, not less.

17. Question 16

    A conscious adult with severe shortness of breath is sitting upright and leaning forward on her hands. Which transport position is most appropriate for this patient?

    • Supine with the legs elevated to improve venous return
    • Upright in the position she finds most comfortableCorrect
    • Left lateral recumbent to protect the airway
    • Supine with the head elevated 15 degrees on a pillow

    Why: Patients in respiratory distress instinctively adopt positions such as the tripod or upright sniffing position because these positions ease the work of breathing, and lying flat typically makes the distress worse. The AEMT should therefore transport a conscious dyspneic patient sitting up in the position of comfort, as the Clinical Guidelines advise: "Patients with severe bronchospasm should be left in the position of comfort (perhaps tripod) whenever possible" (PDF p. 180). Supine positions, with or without a small pillow or leg elevation, increase distress, and the lateral recumbent position is reserved for unresponsive patients who are breathing adequately.

Cross-reference: National Model EMS Clinical Guidelines, Version 3.0, March 2022, PDF p. 180.

18. Question 17

    While taking a history from a responsive medical patient, the AEMT asks, "When did you last eat or drink anything?" Which component of the SAMPLE history mnemonic does this question address?

    • Signs and symptoms
    • Medications
    • Last oral intakeCorrect
    • Events leading up to the illness

    Why: SAMPLE stands for Signs and symptoms, Allergies, Medications, Pertinent past medical history, Last oral intake, and Events leading up to the illness, and a question about when the patient last ate or drank maps directly onto the 'L.' It is not Signs and symptoms, which covers what the patient is currently experiencing, nor Medications, which covers drugs the patient takes. It is also not Events leading up to the illness, which covers what the patient was doing or experiencing right before the call, a distinct piece of history from the timing of the last meal or drink.

Cross-reference: National Model EMS Clinical Guidelines, Version 3.0, March 2022, PDF p. 12.

19. Question 18

    An AEMT is treating a 58-year-old man with severe respiratory distress from a COPD exacerbation. On first contact his heart rate is 138 beats/min and he is using accessory muscles heavily. Fifteen minutes later, his heart rate has dropped to 94 beats/min, but he now appears drowsy and his accessory muscle use has not improved. The AEMT's partner comments that the slower heart rate is a reassuring sign. How should the AEMT respond?

    • Disagree; in this context, a falling heart rate combined with a decreasing level of alertness may indicate exhaustion and impending respiratory failure rather than improvementCorrect
    • Agree; a decreasing heart rate in respiratory distress always indicates improvement
    • Agree, and downgrade the priority of this patient because his vital signs are trending toward normal
    • Disagree, but only because his respiratory rate was not also reported

    Why: In a patient with ongoing severe respiratory distress, a decreasing heart rate is not automatically reassuring; when accessory muscle use persists and the patient becomes less alert, a falling heart rate can instead reflect exhaustion and impending respiratory failure as compensatory mechanisms begin to fail. Treating this trend as reassuring, or as grounds to downgrade the patient's priority, would miss a warning sign that he is deteriorating and needs closer monitoring and probable ventilatory assistance. The concern here is the combination of the vital-sign trend with decreasing alertness and unchanged severe work of breathing, not simply the absence of a reported respiratory rate.

20. Question 19

    EMS is called for a 6-year-old girl with about 12 hours of fever and lethargy. On exam she is difficult to arouse, her neck is stiff, and her mother points out several small, non-blanching purple spots on her legs and trunk that were not present an hour ago. Which is the best interpretation and priority action?

    • The rash is most likely a viral exanthem unrelated to her fever; focus on antipyretic measures and routine transport
    • This combination of fever, altered mental status, nuchal rigidity, and a rapidly spreading petechial/purpuric rash suggests meningococcal meningitis/sepsis, a rapidly progressive life-threatening condition; move quickly through the assessment, check blood glucose, treat symptomatically, and provide prompt transportCorrect
    • Mild neck stiffness in a child without other findings is a normal variant and does not need to be documented
    • Petechiae in a febrile child are clinically significant only if they appear on the face

    Why: Fever, altered mental status, nuchal rigidity, and a spreading petechial or purpuric rash together are the recognized picture of meningococcal meningitis/sepsis in a child, a condition that can progress from appearing mildly ill to coma and death very rapidly. Attributing the rash to a benign viral exanthem, dismissing mild neck stiffness as normal, or requiring facial involvement before taking petechiae seriously would all delay recognition of a true emergency. Because deterioration can be so fast, the correct approach is to move efficiently through the assessment, check glucose (since the hypermetabolic state of sepsis can cause hypoglycemia), treat symptoms supportively, and transport promptly rather than performing a slow, exhaustive on-scene work-up.

21. Question 20

    A 34-year-old man reports a rapidly worsening sore throat and difficulty swallowing that began this morning. He is sitting upright, leaning forward, drooling, and speaking in a muffled voice. His respirations are 24/min with mild inspiratory stridor, and his SpO2 is 96% on room air. Which action is most appropriate?

    • Have the patient lie supine and use a tongue depressor to inspect the posterior pharynx
    • Insert an oropharyngeal airway now to secure the airway before it worsens
    • Have the patient lie back and cough forcefully several times to help clear any obstruction
    • Allow the patient to remain in the position he finds most comfortable, provide oxygen without agitating him, and transport rapidly while prepared to manage a deteriorating airwayCorrect

    Why: This patient's sudden severe sore throat, drooling, muffled voice, tripod-like positioning, and stridor should raise concern for a rapidly progressive infection of the upper airway; deterioration in adults with this kind of presentation can occur quickly and is easily missed because it is more often thought of as a pediatric problem, and treatment of an adult with a potential airway infection like this should focus on maintaining a patent airway. The safest approach is to avoid anything that could agitate him or provoke further swelling, let him remain in the position he tolerates best, give oxygen gently, and transport promptly while prepared for sudden deterioration. Examining the posterior pharynx with a tongue depressor or placing an oropharyngeal airway both instrument an already swollen airway and risk turning partial obstruction into complete obstruction. Repositioning him supine and having him cough forcefully removes him from the position that is helping keep his airway open and does nothing to relieve an infectious, swelling-based obstruction the way it might dislodge a foreign body.

22. Question 21

    A 68-year-old man is found unresponsive to voice in his recliner. He does not open his eyes or speak when the AEMT calls his name, but he moans and pulls his arm away when the AEMT applies pressure to his nail bed. According to the AVPU scale, how should the AEMT classify this patient's level of consciousness?

    • Alert
    • Responsive to verbal stimuli
    • Responsive to painful stimuliCorrect
    • Unresponsive

    Why: The patient does not react to voice, ruling out Alert or Verbal, but he does moan and withdraw from a painful stimulus, which is exactly the behavior that defines the Painful level of AVPU. He is not Unresponsive because a reaction to pain was elicited. He is not Alert because alertness requires the patient to be awake and interactive without any stimulus, and he is not simply 'responsive to verbal stimuli' because calling his name produced no reaction at all. AVPU is meant to be assessed in order from least to most stimulating, stopping at the first level that produces a response, which here is Pain.

23. Question 22

    An AEMT assesses a 58-year-old woman who is breathing 36 times per minute with very shallow chest movement and can speak only two or three words at a time. Her SpO2 is 88% on a nonrebreathing mask. What is the most important reason this breathing pattern requires assisted ventilation rather than supplemental oxygen alone?

    • Rapid breathing exhausts the oxygen in the mask reservoir faster than it can refill.
    • Shallow breaths move air mainly within the dead space, so little fresh gas reaches the alveoli.Correct
    • Tachypnea causes excessive carbon dioxide loss, producing respiratory alkalosis.
    • A rate above 30 breaths/min cannot be measured accurately by pulse oximetry.

    Why: Rapid, shallow breathing moves most of each small breath only through the conducting airways, which do not exchange gas, so alveolar ventilation collapses even though the respiratory rate looks high. That is why a patient who cannot finish a sentence and is desaturating on high-flow oxygen needs the AEMT to assist ventilation and restore an adequate minute volume. A nonrebreathing mask reservoir refills continuously at 15 L/min, so reservoir depletion is not the issue. Shallow tachypnea retains carbon dioxide rather than blowing it off, so alkalosis is not the concern here. Pulse oximetry measures saturation, not respiratory rate, and remains valid at any rate as long as perfusion is adequate.

24. Question 23

    A 66-year-old woman reports chest pressure that began after she fell down a flight of stairs and struck her head. She is confused and has a large scalp hematoma; blood pressure is 154/92 mm Hg. Why should the AEMT withhold nitroglycerin?

    • A possible head injury or intracranial bleed is a contraindication to nitroglycerinCorrect
    • Nitroglycerin is contraindicated whenever the systolic pressure exceeds 150 mm Hg
    • Nitroglycerin cannot be given to patients older than 65 years
    • Chest pressure after a fall is always musculoskeletal, so no cardiac medications are indicated

    Why: Nitroglycerin dilates vessels and lowers blood pressure, and in a patient with a head injury or possible intracranial bleeding it can worsen cerebral perfusion or bleeding, so head injury and intracranial hemorrhage are listed contraindications alongside hypotension and hypovolemia. The pharmacology reference likewise lists increased intracranial pressure and intracranial bleeding as contraindications. A systolic pressure of 154 mm Hg is not a contraindication; hypotension, not hypertension, is the concern. Age alone does not exclude nitroglycerin. Chest pain after trauma can still be cardiac, but the suspected head injury means the drug is withheld and medical control consulted.

25. Question 24

    While changing IV bags on a trauma patient, air enters the line. Shortly afterward the patient becomes dyspneic with cyanosis that does not improve on high-flow oxygen, and breath sounds are unequal. How should the AEMT position this patient for rapid transport?

    • On the left side with the head down, to trap air in the right atrium and ventricleCorrect
    • Supine with the legs elevated
    • Sitting upright with the legs dangling
    • On the right side with the head elevated

    Why: Air introduced through an IV line can lodge in the right side of the heart and obstruct pulmonary blood flow, producing sudden dyspnea, cyanosis unrelieved by oxygen, unequal breath sounds, and shock; placing the patient on the left side with the head lowered traps the air in the right atrium and ventricle where it is less likely to move into the pulmonary circulation. Supine with legs elevated does nothing to confine the air. An upright position lets air rise toward the pulmonary outflow tract. Right-side-down with the head up is the opposite of the intended geometry.

26. Question 25

    Burn wounds are described as having three concentric zones of injury. Which zone contains damaged but potentially viable tissue that good perfusion during prehospital care can help preserve?

    • The zone of coagulation
    • The zone of stasisCorrect
    • The zone of hyperemia
    • The zone of necrosis

    Why: The ring immediately around the central burn, the zone of stasis, has reduced blood flow and inflammation; its cells may die over the next 1 to 2 days if perfusion is poor, so supporting circulation and avoiding burn shock helps convert this tissue toward recovery rather than necrosis. The central zone of coagulation has essentially no blood flow and is already destroyed. The outermost zone of hyperemia is the least injured and generally recovers on its own within about a week to ten days. A zone of necrosis is not one of the three named burn zones.
