Question 1

1. Don surgical masks on both the patient and the crew. (correct answer)
2. Administer a fluid bolus to treat for septic shock.
3. Place the patient in a supine position to assess for Kernig's sign.
4. Immediately request law enforcement to secure the scene.

Explanation: When you encounter a patient with classic signs of bacterial meningitis in a congregate setting like a college dorm, your first priority is protecting yourself and your crew from potential airborne transmission. This scenario presents the textbook triad of meningitis: fever, neck stiffness (nuchal rigidity), and altered mental status, plus photophobia and a petechial rash that suggests meningococcal disease. Answer A is correct because bacterial meningitis, particularly meningococcal meningitis, spreads through respiratory droplets. Surgical masks for both patient and crew provide immediate protection against droplet transmission during the critical initial contact and transport phase. This is standard infectious disease protocol and takes precedence over all other interventions. Answer B addresses a valid concern since septic shock can develop rapidly with meningococcal disease, but fluid resuscitation comes after personal protective equipment is in place. You can't help the patient if you become infected yourself. Answer C involves a physical exam maneuver that's useful for diagnosis but isn't an immediate safety precaution. Kernig's sign testing can wait until after protective measures are established. Answer D is completely unnecessary. This is a medical emergency, not a security issue requiring law enforcement intervention. For NREMT success, remember the hierarchy: scene safety and infection control always come before patient care interventions. When you see signs of infectious disease (especially respiratory or droplet-spread conditions), immediately think "What PPE do I need?" before considering treatment options.

Question 2

1. Administer a 500 mL bolus of normal saline to improve cerebral perfusion.
2. Initiate D5W at a keep-open rate to provide calories to the brain.
3. Withhold all IV fluids to prevent any increase in intracranial pressure.
4. Attach a saline lock and maintain a to-keep-open (TKO) rate. (correct answer)

Explanation: For most ischemic stroke patients, especially those who are hypertensive and not dehydrated, the goal is to maintain euvolemia. A saline lock or running the IV at a TKO rate provides venous access for the hospital without administering a large fluid volume, which could potentially worsen cerebral edema and increase intracranial pressure. A fluid bolus is not indicated without signs of hypoperfusion. D5W is contraindicated as it is hypotonic and can increase cerebral edema.

Question 3

1. Transient ischemic attack (TIA)
2. Ischemic embolic stroke
3. Hemorrhagic stroke (correct answer)
4. Complex migraine headache

Explanation: The patient's symptoms—a sudden, severe 'thunderclap' headache, nausea, and photophobia—are classic signs of a subarachnoid hemorrhage, a type of hemorrhagic stroke. The combination of hypertension, bradycardia, and irregular respirations (Cushing's triad) indicates increasing intracranial pressure, further supporting this diagnosis. TIA and ischemic strokes typically present with focal deficits, not a primary complaint of a severe headache. While a migraine can be severe, the presence of Cushing's triad points to a more catastrophic intracranial event.

Question 4

1. Attempt insertion of a supraglottic airway, apply high-flow oxygen, and establish IV access.
2. Position the patient, provide suction as needed, administer oxygen via non-rebreather mask, and establish IV access. (correct answer)
3. Forcefully restrain the patient to prevent injury, insert a bite block, and request paramedic intercept for medication.
4. Administer oral glucose, apply a cervical collar to protect the spine, and transport immediately.

Explanation: In status epilepticus, the AEMT's priority is supportive care focused on the ABCs. The correct sequence is to position the patient to protect from injury and manage the airway, suction secretions, apply high-flow oxygen to combat hypoxia, and then establish IV access for potential medication administration by higher-level providers. Attempting to insert a supraglottic airway during active seizing is dangerous and likely to cause trauma. Forceful restraint can cause musculoskeletal injury, and bite blocks are not recommended. Oral glucose is contraindicated due to aspiration risk in an unresponsive patient.

Question 5

1. Place the patient in soft restraints to prevent her from harming herself or the crew.
2. Insert a nasopharyngeal airway and assist ventilations with a bag-valve mask.
3. Position the patient in the recovery position and prepare to suction the airway. (correct answer)
4. Assume the combativeness is due to hypoxia and administer a 500 mL fluid bolus.

Explanation: In the immediate postictal phase, patients are often unresponsive with a compromised airway. Sonorous respirations indicate a partial upper airway obstruction, typically by the tongue. Placing the patient in the recovery position uses gravity to help drain secretions and move the tongue forward, opening the airway. Suction should be ready. Restraints should be a last resort and are premature here. Assisting ventilations is not yet indicated as she is breathing at 24/min; the priority is airway patency. A fluid bolus is not indicated.

Question 6

1. Agree with the patient's refusal as his symptoms have resolved and no emergency exists.
2. Advise the patient to take an aspirin and follow up with his primary care physician tomorrow.
3. Strongly encourage transport, explaining that his symptoms indicate a TIA and a high risk of a future stroke. (correct answer)
4. Contact medical control to have the patient's physician called to authorize the refusal of care.

Explanation: This patient has experienced a transient ischemic attack (TIA). A TIA is a major warning sign for an impending ischemic stroke, with the highest risk occurring in the first 24-48 hours. The AEMT's responsibility is to educate the patient on this risk and strongly recommend immediate transport for evaluation. Simply agreeing with the refusal or advising a follow-up visit fails to address the emergent nature of the condition. While contacting medical control is an option, the primary action is patient education and encouraging transport.

Question 7

1. Insert a supraglottic airway and begin positive pressure ventilation. (correct answer)
2. Place the patient in the recovery position and continue high-flow oxygen.
3. Suction the oropharynx and insert an oropharyngeal airway.
4. Request a paramedic intercept for endotracheal intubation.

Explanation: This patient is in respiratory failure. They are breathing inadequately (rate of 8, shallow) and are hypoxic (SpO2 87%) despite high-flow oxygen, indicating a failure to oxygenate and ventilate. The gurgling indicates secretions. The most appropriate AEMT intervention is to secure the airway with a supraglottic device and provide positive pressure ventilations to correct the respiratory failure. Suctioning and an OPA alone will not fix the inadequate rate and depth of breathing. Waiting for a paramedic intercept would cause an unnecessary delay in definitive airway management.

Question 8

1. Reassure the patient that it is not a stroke and advise her to see her doctor within 24 hours.
2. Treat the patient with a high index of suspicion for a stroke and transport for definitive evaluation. (correct answer)
3. Administer diphenhydramine as facial paralysis can be a sign of an allergic reaction.
4. Focus the assessment on potential trauma to the facial nerve and transport non-emergently.

Explanation: While the inability to wrinkle the forehead on the affected side is a classic sign of Bell's Palsy (a peripheral nerve palsy), it is not possible or safe to definitively differentiate it from a stroke in the prehospital setting. Stroke can present atypically. The principle of 'worst first' requires treating any acute onset neurological deficit as a potential stroke until proven otherwise. Therefore, the most prudent action is to treat with a high index of suspicion for stroke and ensure rapid transport to an appropriate facility.

Question 9

1. Speak more loudly and slowly to ensure he can hear and process your questions.
2. Write down your questions on a notepad for him to read and answer.
3. Ask his family members to interpret what he is trying to communicate to you.
4. Use simple gestures and ask yes/no questions that he can answer by nodding. (correct answer)

Explanation: When you encounter a patient with stroke-like symptoms and communication difficulties, identifying the specific type of speech disorder helps guide your assessment approach. This patient shows signs of Wernicke's aphasia (receptive aphasia) - his speech is fluent with normal rhythm but lacks meaningful content, and he becomes frustrated when not understood. The most effective strategy is D) Use simple gestures and ask yes/no questions that he can answer by nodding. Patients with Wernicke's aphasia often retain the ability to understand simple, concrete concepts and can respond to basic yes/no questions through nodding or shaking their head. This bypasses their verbal expression difficulties while still allowing meaningful communication about critical assessment needs. A) Speaking more loudly and slowly is incorrect because this patient doesn't have a hearing problem - his issue is with language processing and meaningful speech production. Increased volume won't improve comprehension and may increase agitation. B) Writing questions down assumes his reading comprehension is intact, but Wernicke's aphasia typically affects both spoken and written language comprehension. This approach likely won't be more effective than verbal communication. C) Having family members interpret is problematic because the patient's speech lacks coherent meaning - even familiar people cannot reliably interpret nonsensical speech patterns. This also wastes valuable assessment time. Study tip for NREMT-AEMT: Learn to distinguish between different types of aphasia. Wernicke's = fluent but meaningless speech; Broca's = meaningful but halting speech. Match your communication strategy to the specific deficit - simple gestures and yes/no questions work best when comprehension is partially preserved.

Question 10

1. The time of the last normal phone call (9:00 PM). (correct answer)
2. The time he was found by his son (8:00 AM).
3. An average time, approximately 2:30 AM.
4. The time is considered unknown, so he is not a candidate for therapy.

Explanation: Stroke questions on the NREMT often test your understanding of the critical time windows for thrombolytic therapy. The key concept here is "last known normal" time - the last moment when you can definitively say the patient was functioning normally without stroke symptoms. The correct approach is to use the most recent time when the patient was confirmed to be neurologically normal. In this scenario, the son spoke with his father at 9:00 PM and reported he was "perfectly fine." This phone conversation provides concrete evidence of normal neurological function at that specific time, making 9:00 PM the last known normal time. Looking at why the other options are incorrect: Option B (8:00 AM) represents when the patient was found, but he already had stroke symptoms at that point, so this cannot be considered "normal." Option C (2:30 AM average) involves speculation - you cannot assume when the stroke occurred or average times together when dealing with such precise treatment windows. Option D incorrectly suggests the time is unknown, but we do have reliable information from the phone call. The last known normal time is crucial because thrombolytic therapy typically has strict time windows (often 3-4.5 hours from symptom onset). In this case, the stroke could have occurred anytime between 9:00 PM and 8:00 AM, potentially exceeding safe treatment windows. Study tip: Always look for the most recent documented time when the patient was confirmed normal through direct observation or reliable communication. Never guess or average times when determining thrombolytic eligibility.

Question 11

1. Submerge the child in a tepid water bath to rapidly lower his temperature.
2. Administer a weight-based dose of oral acetaminophen immediately.
3. Establish an IO line in preparation for a potential second seizure.
4. Remove excessive clothing and blankets to allow for passive cooling. (correct answer)

Explanation: When you encounter a pediatric patient with a suspected febrile seizure, your primary focus should be supportive care and gentle temperature reduction. Febrile seizures are typically self-limiting and occur due to rapid temperature elevation in children between 6 months and 5 years old. The most appropriate intervention is D) Remove excessive clothing and blankets to allow for passive cooling. This approach allows the child's body to naturally dissipate heat through radiation and convection without causing rapid temperature changes that could trigger additional seizures or cause shivering. Since the child is postictal (sleepy but rousable), aggressive interventions aren't warranted. A) Submerging in tepid water is contraindicated because rapid cooling can cause shivering, which actually increases body temperature and oxygen demand. It can also cause peripheral vasoconstriction, trapping heat internally. B) Oral acetaminophen isn't appropriate immediately post-seizure because the child is altered and drowsy, creating an aspiration risk. Additionally, while antipyretics can help with comfort, they don't prevent febrile seizures since these are caused by the rate of temperature rise, not the absolute temperature. C) Establishing an IO line is unnecessarily invasive for a simple febrile seizure. Most febrile seizures don't recur during the same illness episode, and this child is showing normal postictal behavior. Key takeaway: For febrile seizures, think "gentle and supportive." Avoid aggressive cooling methods or unnecessary procedures. Focus on passive cooling measures and monitoring while the child recovers naturally from the postictal state.

Question 12

1. Establish an IV and administer a 500 mL fluid bolus to try to lower the pressure.
2. Contact medical control to request orders for medication to lower his blood pressure below 180 mmHg systolic.
3. Assist the patient in taking his prescribed beta-blocker to manage the hypertensive emergency.
4. Recognize this as permissive hypertension and focus on rapid transport to a stroke center. (correct answer)

Explanation: When you encounter a stroke patient with severe hypertension, you need to understand the concept of permissive hypertension. The brain may be compensating for reduced blood flow by increasing systemic blood pressure to maintain cerebral perfusion pressure. Rapidly lowering blood pressure in acute stroke can worsen brain injury by reducing perfusion to already compromised tissue. Option D is correct because current stroke protocols recognize that elevated blood pressure immediately after stroke onset serves a protective function. Your role is to provide supportive care and ensure rapid transport to a stroke center where specialists can make careful decisions about blood pressure management using continuous monitoring and specific medications. Option A is wrong because fluid boluses don't effectively lower blood pressure and could worsen hypertension by increasing preload. Option B represents a dangerous approach—prehospital blood pressure reduction in stroke patients can cause precipitous drops in cerebral perfusion, potentially extending the stroke. Even with medical control orders, this isn't appropriate emergency care. Option C is also hazardous because beta-blockers can cause unpredictable blood pressure drops without proper monitoring, and you don't know the patient's current medication regimen or potential contraindications. Remember this key principle: in suspected stroke with hypertension, your priority is rapid recognition, supportive care, and immediate transport to a stroke center. Resist the urge to "treat" the high blood pressure—it may be the brain's attempt to save itself. Focus on airway management, oxygen if needed, and getting the patient to definitive care quickly.

Question 13

1. A cerebellar or brainstem stroke (correct answer)
2. Benign paroxysmal positional vertigo (BPPV)
3. An inner ear infection (labyrinthitis)
4. Dehydration with orthostatic hypotension

Explanation: When evaluating dizziness in emergency medicine, you need to distinguish between peripheral causes (inner ear problems) and central causes (brain-related issues). The key is recognizing patterns that suggest serious central nervous system pathology. This patient's presentation strongly suggests a cerebellar or brainstem stroke. The combination of constant vertigo that doesn't change with position, balance problems, and coordination issues (clumsiness with her right hand) points to central pathology. The cerebellum controls balance and coordination, while the brainstem houses vestibular nuclei that process balance information. When these areas are affected by stroke, you see persistent vertigo with neurological deficits. Option B (BPPV) is wrong because BPPV causes brief episodes of vertigo triggered by specific head movements, not constant symptoms. The vertigo would worsen or improve with position changes, which this patient specifically denies. Option C (labyrinthitis) causes constant vertigo but typically doesn't produce the coordination problems seen here. Inner ear infections cause peripheral vertigo without the neurological deficits like hand clumsiness that suggest brain involvement. Option D (dehydration with orthostatic hypotension) would cause lightheadedness that worsens when standing, not spinning vertigo with coordination problems. The stable vital signs also make this less likely. Remember this pattern: constant vertigo plus neurological symptoms (coordination problems, weakness, speech changes) = think stroke. Peripheral causes of dizziness rarely produce additional neurological deficits. Always consider stroke in elderly patients with new-onset constant vertigo and any accompanying neurological signs.

Question 14

1. Administer dextrose 50% due to her altered mental status.
2. Apply a non-rebreather mask at 15 LPM to treat presumed hypoxia.
3. Establish IV access and administer a 250 mL normal saline bolus. (correct answer)
4. Withhold all interventions until a definitive cause is identified.

Explanation: This patient is hypotensive (BP 88/48) and tachycardic (HR 112), indicating a state of shock, which is likely contributing to her altered mental status. After ensuring airway and breathing are adequate, the priority is to address circulation. A 250 mL fluid bolus is a cautious but appropriate first step to treat the hypotension in an elderly patient. Dextrose is not indicated as her blood glucose is normal. Her SpO2 is adequate, so while supplemental oxygen may be applied, it is not the priority over correcting her perfusion.

Question 15

1. Administer 324 mg of aspirin to prevent further clot formation.
2. Obtain a blood glucose level to rule out a stroke mimic. (correct answer)
3. Establish a large-bore IV and administer a 500 mL normal saline bolus.
4. Notify the receiving hospital of a stroke alert and begin rapid transport.

Explanation: The correct answer is to obtain a blood glucose level. Hypoglycemia can perfectly mimic the signs and symptoms of an acute stroke. Given the patient's history of diabetes, this is a critical differential diagnosis that must be ruled out immediately. Administering aspirin is contraindicated until a hemorrhagic stroke has been ruled out at the hospital. A fluid bolus is not indicated and may worsen cerebral edema. Notifying the hospital is important, but checking blood glucose is a more immediate diagnostic step that can be performed simultaneously with transport preparations.

Question 16

1. The stroke screen is negative because arm drift, the most specific sign, is absent; continue with a secondary assessment.
2. The patient has Bell's Palsy, not a stroke; transport is non-emergent.
3. The stroke screen is positive; prioritize transport to the nearest appropriate stroke center. (correct answer)
4. The findings are equivocal; repeat the stroke screen in 5 minutes to see if arm drift develops.

Explanation: The presence of any one of the three signs in the Cincinnati Prehospital Stroke Scale (facial droop, arm drift, or abnormal speech) constitutes a positive screen. This patient exhibits two positive signs (facial droop and slurred speech). This is a strong indicator of a stroke, and the patient requires immediate priority transport to a stroke-capable facility. Delaying transport to repeat the exam or misdiagnosing the condition in the field is inappropriate.

Question 17

1. A generalized tonic-clonic seizure with a rapid postictal recovery.
2. A syncopal episode, likely with a cardiac or orthostatic etiology. (correct answer)
3. A transient ischemic attack affecting the motor cortex.
4. Hypoglycemia secondary to poor oral intake at dinner.

Explanation: The brief shaking movement following a collapse is characteristic of myoclonic jerks due to cerebral hypoperfusion during a syncopal episode, not a true seizure. The patient's rapid return to a normal mental status, pallor, diaphoresis, and situational context (standing up) strongly suggest syncope. The priority is to investigate a potential cardiac cause (e.g., arrhythmia) or orthostatic hypotension, which is a common cause of syncope in the elderly. A seizure would typically have a more prolonged postictal phase.

Question 18

1. Severe alcohol poisoning
2. Opioid overdose (correct answer)
3. Intracranial hemorrhage
4. Diabetic ketoacidosis

Explanation: The classic triad of opioid overdose is respiratory depression, altered mental status, and miosis (pinpoint pupils). While alcohol can cause CNS depression, it typically causes pupils to be midrange and sluggishly reactive. The combination of severe respiratory depression and pinpoint pupils is highly suggestive of an opioid overdose, which may be co-ingested with alcohol. This is a life-threatening condition requiring immediate airway management and ventilation. While an intracranial hemorrhage (specifically a pontine bleed) can also cause pinpoint pupils, opioid overdose is a more common and readily treatable cause to consider first.
