National Registry of Emergency Medical Technicians (NREMT) Paramedic Cognitive Exam — Questions and Answers

Question 1: During ice rescue, EMS should approach a victim through ice by:

Running quickly to distribute weight
Using a ladder bridged across the surface
Walking slowly in single file
Crawling prone to spread body weight over a larger area (Correct answer)

Correct answer: Crawling prone to spread body weight over a larger area

Crawling prone distributes body weight over a larger surface area, reducing point-pressure that could break thin ice.

Question 2: Which spinal injury pattern results from axial loading and is most commonly associated with diving accidents?

Burst fracture (Correct answer)
Hyperextension
Chance fracture
Flexion-distraction

Correct answer: Burst fracture

Burst fractures result from axial loading forces compressing the vertebra and are classic injuries seen in diving accidents and falls from height.

Question 3: In the management of suspected cardiac tamponade in a pulseless patient, which intervention is definitive?

Pericardiocentesis (Correct answer)
Needle decompression of the chest
Administration of epinephrine 1 mg IV
Fluid resuscitation with 1-2 L NS

Correct answer: Pericardiocentesis

Pericardiocentesis, the needle drainage of blood from the pericardial sac, is the definitive treatment for cardiac tamponade.

Question 4: The following are all included in EMS transmissions, EXCEPT:

a citizen notifier
computer-aided dispatch (CAD)
emergency medical dispatcher
online medical control with base station physician (Correct answer)

Correct answer: online medical control with base station physician

EMS transmissions encompass the entire communication process from the initial call to patient handoff. While online medical control with a base station physician is a critical component of patient care communication, it is a *specific type* of interaction that occurs *during* an incident. The other options – computer-aided dispatch (CAD), emergency medical dispatcher, and a citizen notifier – represent the fundamental *components and origins* of the broader EMS transmission *system* that initiates and manages the overall response.

Question 5: When using the SBAR communication tool during a patient handoff, what does the 'R' stand for?

Recommendation (Correct answer)
Response
Report
Review

Correct answer: Recommendation

In SBAR (Situation, Background, Assessment, Recommendation), 'R' stands for Recommendation — the paramedic's suggested next steps for care.

Question 6: During assessment of a patient with altered mental status, you note his breath smells like ammonia. He has a distended abdomen, jaundice, and spider angiomas. What metabolic emergency is most likely?

Hepatic encephalopathy (Correct answer)
Uremic encephalopathy
Wernicke's encephalopathy
Diabetic ketoacidosis

Correct answer: Hepatic encephalopathy

Ammonia breath with signs of liver disease (jaundice, spider angiomas, ascites) and altered mental status indicates hepatic encephalopathy from liver failure.

Question 7: You have successfully resuscitated a 50-year-old patient from cardiac arrest. The patient remains comatose and unable to follow commands. According to the most recent resuscitation guidelines, what is the primary goal of targeted temperature management (TTM) for this patient?

Rapidly inducing deep hypothermia to 30°C.
Alternating between periods of cooling and warming.
Warming the patient to 38°C to prevent infection.
Actively preventing fever by targeting a temperature ≤ 37.5°C. (Correct answer)

Correct answer: Actively preventing fever by targeting a temperature ≤ 37.5°C.

Recent guidelines have shifted the focus of post-cardiac arrest temperature management. The primary goal is now the active prevention of fever. It is recommended to target a core temperature of less than or equal to 37.5°C for patients who remain comatose after the return of spontaneous circulation (ROSC). While earlier protocols focused on inducing moderate hypothermia (32-34°C), current evidence suggests that actively preventing fever is a critical intervention.

Question 8: Crew Resource Management (CRM) in EMS is designed primarily to:

Improve communication and reduce errors in high-stress environments (Correct answer)
Train dispatchers for call prioritization
Reduce ambulance fuel consumption
Standardize medication dosing protocols

Correct answer: Improve communication and reduce errors in high-stress environments

CRM focuses on using all available resources — communication, teamwork, and decision-making — to minimize errors.

Question 9: What is the mechanism of action of magnesium sulfate in the treatment of torsades de pointes?

Acts as a competitive antagonist at potassium channels
Increases heart rate to overdrive the dysrhythmia
Blocks calcium channels and stabilizes cardiac membranes by inhibiting sodium influx (Correct answer)
Prolongs the QT interval to stabilize repolarization

Correct answer: Blocks calcium channels and stabilizes cardiac membranes by inhibiting sodium influx

Magnesium stabilizes cardiac membranes and blocks calcium, interrupting the triggered activity responsible for torsades de pointes.

Question 10: Which vehicle positioning strategy is recommended when an ambulance is blocking a lane at a roadway incident?

Angle the ambulance 45° with the rear toward traffic (Correct answer)
Park perpendicular to the road
Position behind the fire apparatus
Park parallel to traffic flow

Correct answer: Angle the ambulance 45° with the rear toward traffic

Angling the ambulance 45° with the rear toward traffic creates a traffic break and deflects vehicles away from workers.

Question 11: What is the target end-tidal CO2 range for a ventilated traumatic brain injury patient without signs of herniation?

45–55 mmHg
25–30 mmHg
35–45 mmHg (Correct answer)
30–35 mmHg

Correct answer: 35–45 mmHg

Normocapnia (ETCO2 35–45 mmHg) is the target for TBI patients to avoid secondary injury from hypocapnia-induced vasoconstriction or hypercapnia-induced vasodilation.

Question 12: After needle decompression of a tension pneumothorax, the patient's condition does not improve. What is the next step?

Perform needle decompression on the opposite side
Repeat needle decompression at the same site
Perform a finger thoracostomy (Correct answer)
Increase IV fluid rate

Correct answer: Perform a finger thoracostomy

If needle decompression fails to relieve tension pneumothorax, a finger thoracostomy provides a definitive prehospital decompression by creating an open chest wall opening.

Question 13: A patient with Type 1 diabetes is found unconscious with Kussmaul respirations and a fruity odor on breath. Blood glucose is 520 mg/dL. What acid-base disturbance is present?

Metabolic acidosis (Correct answer)
Respiratory alkalosis
Respiratory acidosis
Metabolic alkalosis

Correct answer: Metabolic acidosis

DKA causes metabolic acidosis from ketoacid accumulation, and Kussmaul respirations represent the respiratory compensation attempt.

Question 14: An 82-year-old female presents with acute onset of confusion, generalized weakness, and shortness of breath. She denies any chest pain. Her medical history includes hypertension and diabetes. Which condition should the paramedic maintain the highest index of suspicion for?

Sepsis
Acute Myocardial Infarction (Correct answer)
Pulmonary Embolism
Hypoglycemia

Correct answer: Acute Myocardial Infarction

Elderly patients, especially women and those with diabetes, frequently present with atypical symptoms of Acute Myocardial Infarction (AMI). Classic chest pain may be absent, and they may instead present with symptoms like weakness, confusion, syncope, shortness of breath, or nausea.

Question 15: What is the normal two-way radio mobile range?

10-15 miles (Correct answer)
30-45 miles
40-55 miles
20-25 miles

Correct answer: 10-15 miles

The typical effective range for a mobile two-way radio (vehicle-mounted) operating in a relatively flat, unobstructed environment is generally 10-15 miles. This range can be influenced by terrain, obstructions, antenna type, and power output, but 10-15 miles is a common practical estimate for reliable communication.

Question 16: What is a gadget that receives a low-power portable radio transmission on one frequency and sends it out again on a different frequency with a larger power?

Voter
Encoder
Repeater (Correct answer)
Tweaker

Correct answer: Repeater

A repeater is an electronic device that receives a radio signal and retransmits it at a higher power or on a different frequency, extending the range and improving the clarity of radio communications. This is crucial in EMS for maintaining communication over large areas, through obstructions, or with low-power portable radios.

Question 17: Which of the following is the CORRECT tidal volume to deliver when ventilating an adult with a BVM?

1000-1200 mL over 3 seconds
300-400 mL over 0.5 seconds
500-600 mL over 1 second (Correct answer)
800-1000 mL over 2 seconds

Correct answer: 500-600 mL over 1 second

Adult BVM ventilation should deliver 500-600 mL (enough to produce visible chest rise) over approximately 1 second to minimize gastric inflation.

Question 18: A patient with a suspected C-spine injury requires intubation. Which technique is most appropriate?

Blind digital intubation without any stabilization
Nasotracheal intubation with hyperextension
Orotracheal intubation with manual in-line stabilization (Correct answer)
Defer intubation until CT imaging is complete

Correct answer: Orotracheal intubation with manual in-line stabilization

Orotracheal intubation with manual in-line cervical stabilization (MILS) maintains the airway while minimizing cervical spine movement.

Question 19: A patient presents with a wide-complex tachycardia at 180 bpm. The patient is hemodynamically unstable with a BP of 70/40 mmHg. What is the most appropriate immediate intervention?

Unsynchronized defibrillation at 200 J
Synchronized cardioversion starting at 100 J (Correct answer)
Administer amiodarone 150 mg IV
Adenosine 6 mg rapid IV push

Correct answer: Synchronized cardioversion starting at 100 J

Unstable wide-complex tachycardia requires immediate synchronized cardioversion; pharmacologic therapy is reserved for stable patients.

Question 20: Which of the following correctly describes pulseless electrical activity (PEA)?

Organized electrical activity on ECG but no detectable pulse (Correct answer)
Rapid narrow-complex tachycardia without a palpable pulse
Disorganized chaotic electrical activity with no pulse
No electrical activity and no pulse

Correct answer: Organized electrical activity on ECG but no detectable pulse

PEA is defined as organized electrical activity visible on ECG without a corresponding palpable pulse or blood pressure.

Question 21: What is the maximum depth at which chest compressions should be performed in an adult during CPR?

Exactly 2 inches (5 cm)
At least 2 inches (5 cm) with a maximum of 2.4 inches (6 cm) (Correct answer)
At least 2.5 inches (6.5 cm) with no maximum
As deep as possible to maximize output

Correct answer: At least 2 inches (5 cm) with a maximum of 2.4 inches (6 cm)

AHA guidelines specify compression depth of at least 2 inches but no more than 2.4 inches to optimize perfusion while avoiding injury.

Question 22: How much gas is typically expelled or inhaled during a respiratory cycle?

Tidal volume (Correct answer)
Alveolar volume
Minute volume
Dead space volume

Correct answer: Tidal volume

Tidal volume is the amount of air that is typically inspired or expelled during a single, normal respiratory cycle at rest. It represents the volume of air exchanged with each breath. This measurement is crucial for assessing respiratory function and ensuring adequate ventilation.

Question 23: The revised trauma score (RTS) is calculated using which three parameters?

Heart rate, respiratory rate, and pupillary response
Systolic BP, heart rate, and GCS
GCS, oxygen saturation, and mechanism of injury
Glasgow Coma Scale, systolic blood pressure, and respiratory rate (Correct answer)

Correct answer: Glasgow Coma Scale, systolic blood pressure, and respiratory rate

The RTS combines GCS, systolic blood pressure, and respiratory rate, each coded and weighted to produce a score that correlates with survival probability.

Question 24: Personal flotation devices (PFDs) used in swift-water rescue must be rated as which USCG type?

Type III or Type V whitewater-rated PFD (Correct answer)
Any Coast Guard-approved device
Type II near-shore buoyant vest
Type I offshore life jacket only

Correct answer: Type III or Type V whitewater-rated PFD

Type III or Type V whitewater-specific PFDs provide the mobility and rescue features required for swift-water operations.

Question 25: A 45-year-old female presents with a regular, narrow-complex tachycardia at a rate of 180/min. She is pale, diaphoretic, and has a blood pressure of 78/50 mmHg. Which of the following is the most appropriate initial intervention?

Administer a 150 mg bolus of Amiodarone over 10 minutes.
Administer a 6 mg rapid IV push of Adenosine.
Attempt vagal maneuvers, such as the Valsalva maneuver.
Perform synchronized cardioversion. (Correct answer)

Correct answer: Perform synchronized cardioversion.

The patient is exhibiting clear signs of instability (hypotension, pallor, diaphoresis) due to the tachyarrhythmia. In cases of unstable tachycardia, immediate synchronized cardioversion is the indicated treatment to rapidly restore a stable rhythm and improve perfusion. While Adenosine is appropriate for stable SVT, the patient's instability makes electrical therapy the priority.

Question 26: You respond to a 45-year-old male with massive facial trauma after an assault. He is unconscious, breathing agonally, and has significant bleeding in the oropharynx that suctioning cannot control. You are unable to intubate or ventilate with a BVM. What is the most appropriate next step?

Place the patient in the recovery position and transport rapidly.
Attempt a nasotracheal intubation.
Insert a laryngeal mask airway (LMA).
Perform a surgical cricothyrotomy. (Correct answer)

Correct answer: Perform a surgical cricothyrotomy.

This patient is in a 'can't intubate, can't ventilate' situation. A surgical cricothyrotomy is indicated when other, less invasive, methods of securing an airway have failed or are impossible due to conditions like massive facial trauma, clenched jaw, or severe airway swelling. An LMA would likely be ineffective due to the bleeding, and nasotracheal intubation is often contraindicated in severe facial trauma. The patient requires an immediate definitive airway.

Question 27: Which of the following is the preferred initial energy setting for defibrillation of ventricular fibrillation with a biphasic defibrillator?

50 J
120-200 J as recommended by the manufacturer (Correct answer)
360 J
200 J monophasic equivalent

Correct answer: 120-200 J as recommended by the manufacturer

Biphasic defibrillators should be used at the manufacturer-recommended dose (120-200 J); if unknown, use the maximum available.

Question 28: What information must a caller give the dispatcher first?

Condition of the patient
Nature of the event
Other hazardous conditions
Name and call-back number (Correct answer)

Correct answer: Name and call-back number

While the nature of the event and location are critical, dispatchers are trained to first obtain the caller's name and call-back number. This ensures that if the call is disconnected, the dispatcher can re-establish contact, which is vital for gathering further information or providing updates. This is a standard protocol in emergency communications.

Question 29: Which of the following is NOT something that can be evaluated while the patient is still trapped?

Extent of wounds (Correct answer)
Vital signs
Patient responsiveness
Airway constriction

Correct answer: Extent of wounds

While a patient is still trapped, paramedics can typically assess immediate life threats like airway constriction, patient responsiveness (level of consciousness), and vital signs (pulse, breathing). However, a full and detailed assessment of the *extent* of all wounds, especially internal or hidden injuries, is often difficult or impossible until the patient is disentangled and fully accessible. This comprehensive evaluation usually occurs once the patient is freed.

Question 30: A 28-year-old female who is 36 weeks pregnant is found actively seizing. Her partner reports a recent history of severe headaches, visual disturbances, and significant swelling in her hands and feet. Her blood pressure is 190/110 mmHg. What is the most appropriate medication to treat this patient's condition?

Labetalol
Furosemide
Magnesium Sulfate (Correct answer)
Diazepam

Correct answer: Magnesium Sulfate

This patient is presenting with classic signs and symptoms of eclampsia, which is defined as seizures in a patient with preeclampsia. Magnesium sulfate is the first-line anticonvulsant for both treating active eclamptic seizures and preventing recurrence. While benzodiazepines like diazepam can be used for refractory seizures and labetalol for hypertension, magnesium sulfate is the primary treatment for the underlying cause of the seizures.

Question 31: What makes croup distinctive?

Drooling
Child prefers to sit up
Occasional stridor
Slow onset (Correct answer)

Correct answer: Slow onset

Croup (laryngotracheobronchitis) is typically characterized by a slow, gradual onset, often starting with cold-like symptoms that progress over a few days to the classic barking cough, inspiratory stridor, and hoarseness. This distinguishes it from conditions like epiglottitis, which has a rapid onset and is associated with drooling and a preference to sit up.

Question 32: Which finding is most indicative of a tension pneumothorax in a trauma patient?

Tracheal deviation away from the affected side (Correct answer)
Paradoxical chest wall movement
Subcutaneous emphysema only
Bilateral absent breath sounds

Correct answer: Tracheal deviation away from the affected side

Tracheal deviation away from the affected side is a hallmark late sign of tension pneumothorax as mediastinal structures shift under increasing pressure.

Question 33: A 10-month-old presents limp with bulging fontanelle and a history of vomiting. Parents report the baby 'fell off the changing table.' What injury pattern is most concerning?

Epidural hematoma from arterial injury
Isolated clavicle fracture
Skull fracture from direct impact
Retinal hemorrhages and subdural hematoma consistent with shaken baby syndrome (Correct answer)

Correct answer: Retinal hemorrhages and subdural hematoma consistent with shaken baby syndrome

Retinal hemorrhages combined with subdural hematoma and an inconsistent history are classic findings of abusive head trauma (shaken baby syndrome).

Question 34: For a witnessed, monitored VF arrest in a patient with an implanted pacemaker, how should defibrillator pads be positioned?

Standard anterior-apex positioning is always acceptable regardless of device location
At least 8 cm away from the pacemaker generator (Correct answer)
Posterior-anterior positioning only
Directly over the pacemaker generator for best conduction

Correct answer: At least 8 cm away from the pacemaker generator

Defibrillator pads should be placed at least 8 cm from an implanted device to prevent damage to the pacemaker and ensure effective current delivery.

Question 35: When lifting a heavy patient, which body mechanics rule is MOST important to prevent back injury?

Bend at the waist and keep legs straight
Use only one hand for lighter loads
Twist the torso to change direction quickly
Keep the load close to the body and lift with the legs (Correct answer)

Correct answer: Keep the load close to the body and lift with the legs

Keeping the load close and lifting with leg muscles protects the spine from compressive and shear forces.

Question 36: Which mechanism of injury MOST commonly causes aortic transection?

Fall from less than 10 feet
High-speed deceleration crash with anterior chest impact (Correct answer)
Direct lateral blow to the thorax
Penetrating abdominal trauma

Correct answer: High-speed deceleration crash with anterior chest impact

Aortic transection typically occurs at the ligamentum arteriosum due to shear forces in high-speed deceleration crashes, most often anterior chest impacts.

Question 37: During cardiac arrest resuscitation, epinephrine 1mg IV/IO should be administered every:

2 minutes
3–5 minutes (Correct answer)
5–10 minutes
Once only per resuscitation

Correct answer: 3–5 minutes

The AHA recommends epinephrine 1mg IV/IO every 3–5 minutes during cardiac arrest.

Question 38: A patient has a sucking chest wound. After applying a vented chest seal, the patient's condition deteriorates with increasing respiratory distress and hypotension. The next step is:

Perform needle decompression at the 2nd intercostal space bilaterally immediately
Apply a second unvented occlusive dressing over the first
Remove or burp the chest seal and reassess for tension pneumothorax (Correct answer)
Administer a 500 mL fluid bolus

Correct answer: Remove or burp the chest seal and reassess for tension pneumothorax

Deterioration after chest seal application suggests conversion to tension pneumothorax; temporarily lifting (burping) the seal releases trapped air and is the first response.

Question 39: Which of the following is the BEST indicator that an incident command system is functioning effectively at an MCI?

Resources are being deployed in an orderly and coordinated manner (Correct answer)
All responders are using the same radio frequency
The Incident Commander is the most experienced paramedic
Patients are transported before triage is completed

Correct answer: Resources are being deployed in an orderly and coordinated manner

Effective ICS is demonstrated by organized, coordinated resource deployment that prevents freelancing and ensures all tasks are assigned and tracked.

Question 40: In a patient with suspected spinal injury who is combative and cannot be immobilized safely, the best approach is:

Immobilize the head only with a cervical collar and transport
Abandon all spinal precautions and focus on other injuries
Use chemical restraint and then immobilize once sedated (Correct answer)
Physically restrain the patient and force full immobilization

Correct answer: Use chemical restraint and then immobilize once sedated

Chemical restraint followed by appropriate spinal motion restriction is safer than forceful immobilization, which can cause additional injury to both patient and providers.

Question 41: A 42-year-old male presents with sudden onset crushing chest pain, diaphoresis, and nausea. His 12-lead ECG shows 2 mm ST elevation in leads II, III, and aVF. Which coronary artery is MOST likely occluded?

Left anterior descending artery
Left circumflex artery
Left main coronary artery
Right coronary artery (Correct answer)

Correct answer: Right coronary artery

ST elevation in leads II, III, and aVF (inferior leads) indicates an inferior wall MI, most commonly caused by right coronary artery occlusion.

Question 42: A 45-year-old male presents with wheezing, urticaria, hypotension (BP 70/40), and stridor after eating shellfish. What is the FIRST drug to administer?

Diphenhydramine 50 mg IV
Epinephrine 0.3-0.5 mg IM (Correct answer)
Albuterol via nebulizer
Methylprednisolone 125 mg IV

Correct answer: Epinephrine 0.3-0.5 mg IM

Epinephrine IM is the first-line treatment for anaphylaxis due to its immediate alpha and beta adrenergic effects.

Question 43: A patient requiring rapid sequence intubation is hypertensive and tachycardic with head trauma. Which induction agent is RELATIVELY contraindicated?

Propofol
Ketamine (Correct answer)
Midazolam
Etomidate

Correct answer: Ketamine

Ketamine increases intracranial pressure via sympathomimetic effects, making it relatively contraindicated in isolated head trauma with elevated ICP.

Question 44: Which anatomical landmark is used to identify the cricothyroid membrane for cricothyrotomy?

Space between the cricoid cartilage and first tracheal ring
Space between the thyroid cartilage and cricoid cartilage (Correct answer)
Space between the first and second tracheal rings
Space between the hyoid bone and thyroid cartilage

Correct answer: Space between the thyroid cartilage and cricoid cartilage

The cricothyroid membrane lies between the thyroid cartilage superiorly and the cricoid cartilage inferiorly and is palpated in the midline.

Question 45: Which of the following represents the correct interpretation of a QTc interval greater than 500 ms?

Significantly prolonged, associated with risk of Torsades de Pointes (Correct answer)
Sign of hyperkalemia
Indicates accelerated idioventricular rhythm
Normal variant in elderly patients

Correct answer: Significantly prolonged, associated with risk of Torsades de Pointes

A QTc >500 ms significantly increases the risk of Torsades de Pointes, a life-threatening polymorphic ventricular tachycardia.

Question 46: What should be done initially when managing an asthma attack in a child?

Administer supplemental, humidified oxygen
Administer an inhaled beta agonist (Correct answer)
Establish an airway
Administer a steroid preparation

Correct answer: Administer an inhaled beta agonist

The initial and most critical step in managing an acute asthma attack in a child is to administer a rapid-acting inhaled beta agonist, such as albuterol. These medications quickly relax the smooth muscles of the airways, relieving bronchospasm and improving airflow. While oxygen, steroids, and airway management are important, bronchodilator administration is the immediate priority for reversing the primary problem of bronchoconstriction.

Question 47: The Cincinnati Prehospital Stroke Scale is NOT part of trauma assessment; however, which trauma tool assesses CNS status in the primary survey?

Revised Trauma Score
Hunt-Hess scale
CPSS
AVPU scale (Correct answer)

Correct answer: AVPU scale

The AVPU scale (Alert, Voice, Pain, Unresponsive) provides a rapid CNS assessment during the primary survey's neurological component.

Question 48: What kind of management must the sector officer employ?

Passive
Aggressive
Cooperative (Correct answer)
Assumptive

Correct answer: Cooperative

A sector officer, also known as a branch director or group supervisor in the Incident Command System, must employ cooperative management. This involves working collaboratively with other sector officers, subordinates, and the Incident Commander to ensure coordinated efforts and effective resource utilization. Cooperative management fosters teamwork and ensures all operational objectives are met safely and efficiently.

Question 49: Which waveform on capnography indicates a patient is rebreathing CO2 due to an incompetent expiratory valve?

Elevated baseline above zero (Correct answer)
Absent waveform
Shark fin waveform
Prolonged plateau phase

Correct answer: Elevated baseline above zero

An elevated CO2 baseline above zero on capnography indicates rebreathing of CO2, often due to an incompetent expiratory valve or exhausted CO2 absorber.

Question 50: Which of the following is the correct sequence of events confirming ETT placement?

SpO2 reading → chest X-ray → ETCO2 → auscultation
Auscultation only → secure tube → monitor SpO2
Direct visualization through cords → bilateral breath sounds → chest rise → waveform capnography (Correct answer)
Direct visualization → ETCO2 → chest rise → SpO2 → auscultation

Correct answer: Direct visualization through cords → bilateral breath sounds → chest rise → waveform capnography

Best practice: visualize ETT passing through the cords, then confirm with chest rise, bilateral breath sounds, and continuous waveform capnography.

Question 51: What is the PRIMARY advantage of using video laryngoscopy over direct laryngoscopy?

Allows intubation without a stylet
Eliminates the need for RSI medications
Faster intubation time in all cases
Improved glottic visualization without requiring direct line of sight (Correct answer)

Correct answer: Improved glottic visualization without requiring direct line of sight

Video laryngoscopy provides a magnified, indirect view of the glottis on a screen, improving visualization especially in difficult airways.

Question 52: The 'cold zone' at a hazmat MCI is the appropriate location for:

Entry team preparation and PPE donning
Technical rescue operations and victim extraction
Command post, staging, and treatment of decontaminated patients (Correct answer)
Decontamination of ambulatory patients

Correct answer: Command post, staging, and treatment of decontaminated patients

The cold zone is the safe, uncontaminated area where command, staging, and treatment of already-decontaminated patients occur.

Question 53: Which of the following describes the proper body mechanics for lifting a heavy patient on a stretcher?

Keep your feet close together to concentrate your lifting power.
Bend at your waist and use a slight twisting motion to smoothly guide the stretcher.
Keep your arms extended as far as possible to improve leverage during the lift.
Lift with your back in a straight, upright position, using the powerful muscles of your legs and glutes. (Correct answer)

Correct answer: Lift with your back in a straight, upright position, using the powerful muscles of your legs and glutes.

Proper body mechanics are crucial to prevent career-ending back injuries. The key is to maintain a straight, neutral spine and use the large, powerful muscles of the legs and glutes to perform the lift. This is achieved by squatting, keeping the back straight, and lifting by extending the legs.

Question 54: What is the most critical requirement that must be fulfilled for an EMT to assist a patient with angina who wants to take their nitroglycerin?

The patient must be experiencing severe chest pain.
The patient's systolic blood pressure must be above 100 mm Hg.
The nitroglycerin must be administered sublingually.
The EMT must have medical control. (Correct answer)

Correct answer: The EMT must have medical control.

While specific conditions like systolic blood pressure above 100 mm Hg and sublingual administration are important considerations for nitroglycerin, the overarching and most critical requirement for an EMT to administer or assist with any medication is to have medical control. This means receiving explicit permission or following standing orders from a physician or medical director. Without medical control, an EMT cannot legally or ethically administer medication.

Question 55: You are treating a patient with signs of anaphylaxis including urticaria, bronchospasm, and hypotension. After epinephrine 1:1000 0.3 mg IM, the patient's condition worsens. What is the next step?

Administer methylprednisolone 125 mg IV
Repeat epinephrine 1:1000 0.3 mg IM
Establish IV access and begin epinephrine infusion (Correct answer)
Administer diphenhydramine 50 mg IV

Correct answer: Establish IV access and begin epinephrine infusion

Refractory anaphylaxis unresponsive to IM epinephrine requires IV epinephrine infusion (1:10,000 or infusion) along with aggressive IV fluid resuscitation.

Question 56: A patient has third-degree (complete) heart block with a ventricular rate of 30 bpm and hypotension. Which treatment is most appropriate?

Transcutaneous pacing (Correct answer)
Adenosine 6mg IV push
Amiodarone 300mg IV
Diltiazem 0.25 mg/kg IV

Correct answer: Transcutaneous pacing

Transcutaneous pacing is the definitive prehospital treatment for symptomatic third-degree heart block.

Question 57: You are treating a 55-year-old female for symptomatic bradycardia with a heart rate of 38 and signs of poor perfusion. She has a history of a heart transplant. Which of the following interventions is LEAST likely to be effective for this patient?

Dopamine infusion
Epinephrine infusion
Transcutaneous pacing
Atropine sulfate (Correct answer)

Correct answer: Atropine sulfate

Atropine works by blocking the vagus nerve's effect on the heart. In heart transplant patients, the nerve connections to the heart are severed (denervated), rendering atropine ineffective. Transcutaneous pacing and infusions of chronotropic drugs like epinephrine or dopamine are the appropriate treatments.

Question 58: In ICS, a 'branch' is established when:

The number of divisions or groups exceeds the span of control (Correct answer)
Two or more agencies are operating under unified command
Air operations are integrated with ground operations
The incident spans more than one operational period

Correct answer: The number of divisions or groups exceeds the span of control

A branch is added between the Operations Section Chief and Divisions/Groups when the number of groups or divisions exceeds manageable span of control.

Question 59: Which of the following is NOT regarded as one of the signs and symptoms of the patient?

Obstetrical conditions
Behavioral issues
The patient's last oral intake (Correct answer)
Environmental emergencies

Correct answer: The patient's last oral intake

Signs and symptoms are observable indications or subjective feelings reported by the patient that relate to their current medical condition. Obstetrical conditions, behavioral issues, and environmental emergencies are categories of medical problems that present with specific signs and symptoms. The patient's last oral intake, while important for medical history (e.g., for diabetic emergencies or before surgery), is not itself a sign or symptom but rather a piece of historical information.

Question 60: What is the primary mechanism of action by which adenosine terminates stable, narrow-complex supraventricular tachycardia (SVT)?

It acts as a potent beta-blocker, decreasing myocardial contractility.
It temporarily blocks conduction through the atrioventricular (AV) node. (Correct answer)
It increases sympathetic tone, causing vasoconstriction and increasing heart rate.
It blocks sodium channels in the ventricular myocardium, slowing repolarization.

Correct answer: It temporarily blocks conduction through the atrioventricular (AV) node.

Adenosine's primary antiarrhythmic effect is to slow or completely block electrical conduction through the AV node. This action interrupts the re-entry circuit that is responsible for most forms of SVT, allowing the sinoatrial (SA) node to regain control and restore a normal sinus rhythm.

Question 61: Which of the following is the CORRECT method for sizing an oropharyngeal airway (OPA)?

From the center of the mouth to the angle of the jaw
From the corner of the mouth to the earlobe (Correct answer)
From the center of the lips to the mastoid process
From the corner of the mouth to the tip of the earlobe

Correct answer: From the corner of the mouth to the earlobe

An OPA is sized by measuring from the corner of the patient's mouth to the earlobe (or center of mouth to angle of jaw), ensuring proper fit.

Question 62: A patient presents with symptomatic bradycardia at 38 bpm unresponsive to atropine. What is the next intervention?

Initiate transcutaneous pacing (Correct answer)
Administer a second dose of atropine 1 mg IV
Synchronized cardioversion at 50 J
Administer adenosine 6 mg IV

Correct answer: Initiate transcutaneous pacing

When atropine fails to treat symptomatic bradycardia, transcutaneous pacing is the next step while preparing for transvenous pacing.

Question 63: A construction worker is found unresponsive after suspected carbon monoxide exposure. His skin appears cherry red. SpO2 reads 99%. What is the CORRECT interpretation?

The reading confirms CO poisoning
The patient is adequately oxygenated
The patient is hyperoxic and oxygen should be withheld
SpO2 is falsely elevated due to carboxyhemoglobin (Correct answer)

Correct answer: SpO2 is falsely elevated due to carboxyhemoglobin

Pulse oximetry cannot differentiate oxyhemoglobin from carboxyhemoglobin, so it reads falsely high in CO poisoning — treat with 100% O2 regardless.

Question 64: During a multiple-casualty incident, a patient tagged BLACK in START triage is classified as:

Immediate — needs care now
Minor — walking wounded
Delayed — stable but needs care
Expectant — deceased or unsurvivable (Correct answer)

Correct answer: Expectant — deceased or unsurvivable

Black tags in START triage indicate patients who are deceased or have injuries incompatible with survival given available resources.

Question 65: During rapid sequence intubation, succinylcholine is contraindicated in a patient with crush injuries from 10 days ago. Why?

Upregulation of acetylcholine receptors leads to life-threatening hyperkalemia (Correct answer)
Myoglobin binds succinylcholine causing prolonged paralysis
It causes bronchospasm in trauma patients
It prolongs the QT interval in traumatized muscle

Correct answer: Upregulation of acetylcholine receptors leads to life-threatening hyperkalemia

After 48–72 hours, denervated or damaged muscle upregulates acetylcholine receptors; succinylcholine causes massive potassium efflux, potentially causing cardiac arrest.

Question 66: A 19-year-old presents with hallucinations, agitation, and tachycardia after ingesting psilocybin mushrooms. Which intervention is most appropriate?

Administer naloxone 0.4 mg IV immediately
Provide a calm environment and consider benzodiazepines for severe agitation (Correct answer)
Administer flumazenil 0.2 mg IV
Apply physical restraints immediately and give haloperidol

Correct answer: Provide a calm environment and consider benzodiazepines for severe agitation

Hallucinogen intoxication is best managed with a calm, quiet environment and benzodiazepines for severe agitation; physical restraints alone can worsen agitation and cause rhabdomyolysis.

Question 67: During a two-person CPR in the ambulance while en route, which safety rule applies to the provider performing compressions?

The provider must wear a harness attached to the stretcher
The provider must be seated and belted at all times
The provider should stand and hold a grab rail for balance
The provider may kneel unrestrained on the squad bench (Correct answer)

Correct answer: The provider may kneel unrestrained on the squad bench

When CPR must continue en route, the provider may kneel unrestrained on the squad bench while all other crew members remain belted.

Question 68: A 22-year-old male presents with a single stab wound to the right side of his chest. He is anxious, tachycardic at 130 bpm, and hypotensive at 80/50 mmHg. You note absent breath sounds on the right, jugular vein distention, and tracheal deviation to the left. What is the most critical immediate intervention?

Apply an occlusive dressing to the chest wound.
Initiate a rapid fluid bolus with normal saline.
Perform needle decompression of the right chest. (Correct answer)
Apply a high-flow oxygen mask.

Correct answer: Perform needle decompression of the right chest.

The patient's signs and symptoms (hypotension, JVD, absent breath sounds, and tracheal deviation) are classic for a tension pneumothorax, which is an immediate life-threatening emergency. Needle decompression is the critical intervention to relieve the pressure in the pleural space, allowing the lung to re-expand and relieving pressure on the heart and great vessels.

Question 69: A paramedic is injured on the scene and cannot complete patient care. The best immediate action is to:

Transport the patient immediately without documentation
Continue treating the patient until help arrives
Refuse all further care and await an ambulance for yourself
Notify dispatch and request additional resources while ensuring scene safety (Correct answer)

Correct answer: Notify dispatch and request additional resources while ensuring scene safety

Notifying dispatch allows additional resources to be sent while ensuring the patient still receives necessary care.

Question 70: Which waveform on capnography indicates correct endotracheal tube placement?

Flat waveform at 0 mmHg
Saw-tooth waveform
Square waveform with EtCO2 35-45 mmHg (Correct answer)
Spike-only waveform

Correct answer: Square waveform with EtCO2 35-45 mmHg

A square capnography waveform with EtCO2 between 35-45 mmHg confirms tracheal placement with normal ventilation.

Question 71: A patient with atrial fibrillation has a ventricular rate of 140 bpm and a BP of 88/60 mmHg with altered mental status. What is the most appropriate intervention?

Diltiazem 15-20 mg IV over 2 minutes
Synchronized cardioversion (Correct answer)
Amiodarone 150 mg IV over 10 minutes
Metoprolol 5 mg IV to control rate

Correct answer: Synchronized cardioversion

Unstable atrial fibrillation with hemodynamic compromise requires immediate synchronized cardioversion to restore sinus rhythm.

Question 72: Which START triage category is assigned to a patient who is breathing after a head-tilt/chin-lift but has a respiratory rate of 32 breaths per minute?

Green
Yellow
Red (Correct answer)
Black

Correct answer: Red

A respiratory rate above 30 breaths per minute after repositioning classifies the patient as Red (Immediate) in START triage.

Question 73: When performing an IO insertion on a pediatric patient, which is the PREFERRED primary site?

Distal humerus
Proximal tibia, 2 cm below the tibial tuberosity (Correct answer)
Iliac crest
Distal femur

Correct answer: Proximal tibia, 2 cm below the tibial tuberosity

The proximal tibia is the preferred primary IO site in pediatric patients due to its large, flat medial surface and ease of identification.

Question 74: You have just assisted with a field delivery. The placenta has delivered, but the mother continues to have heavy, bright red vaginal bleeding. On palpation, her uterine fundus feels soft and "boggy." Which of the following is the most important initial intervention?

Perform a firm, vigorous fundal massage. (Correct answer)
Administer a 2-liter bolus of Lactated Ringer's.
Apply a pelvic binder.
Place the patient in a Trendelenburg position.

Correct answer: Perform a firm, vigorous fundal massage.

The clinical presentation of a soft, boggy uterus combined with heavy postpartum bleeding is indicative of uterine atony, the most common cause of postpartum hemorrhage. The most critical initial intervention is to perform a vigorous fundal massage to stimulate the uterus to contract, which constricts the blood vessels at the placental site and controls the bleeding. Fluid resuscitation is important but secondary to controlling the source of the bleed.

Question 75: A paramedic is treating a patient in pulseless electrical activity (PEA). Which of the following is considered one of the reversible 'H' causes that should be immediately assessed and managed?

Tension Pneumothorax
Hypoxia (Correct answer)
Thrombosis (pulmonary)
Tamponade (cardiac)

Correct answer: Hypoxia

The reversible causes of PEA are often remembered by the 'H's and T's' mnemonic. Hypoxia is one of the 'H' causes, along with Hypovolemia, Hydrogen ion (acidosis), Hypo/hyperkalemia, and Hypothermia. Tension pneumothorax, Tamponade, and Thrombosis are all part of the 'T' causes.

Question 76: During a vehicle rescue, which technique refers to the controlled removal of the roof to provide full patient access?

Dash roll
Total roof removal (Correct answer)
Third-door conversion
A-post displacement

Correct answer: Total roof removal

Total roof removal involves cutting all roof posts and removing the entire roof to provide unobstructed access for spinal precautions and patient extrication.

Question 77: Which age group should be questioned away from the parents?

1-3 years
12-15 years (Correct answer)
6-12 years
3-5 years

Correct answer: 12-15 years

When there are concerns about child abuse, adolescents in the 12-15 year age group should ideally be questioned away from their parents. At this age, children are typically mature enough to articulate their experiences and feelings, and separating them from parents can provide a safer, more open environment for disclosure without fear of reprisal or influence. This allows for a more accurate and unbiased account.

Question 78: How should the majority of communications between the paramedics and the sector officer be conducted?

Two-way radio
Cellular phone
Face-to-face (Correct answer)
Written order

Correct answer: Face-to-face

While two-way radios are essential for broader communication in an Incident Command System, the majority of direct communication between paramedics and their immediate supervisor, the Sector Officer, should ideally be face-to-face. This allows for clearer understanding, visual assessment of the situation, and reduces radio traffic, especially in a chaotic mass casualty incident.

Question 79: Which lung compliance finding is consistent with tension pneumothorax in a ventilated patient?

Sudden increase in peak airway pressures with decreased tidal volume delivery (Correct answer)
Increased tidal volume delivery at the same pressure
Decreasing peak airway pressures over time
Stable airway pressures with declining SpO2

Correct answer: Sudden increase in peak airway pressures with decreased tidal volume delivery

Tension pneumothorax causes the affected lung to collapse and mediastinal shift, dramatically increasing airway resistance and peak pressures while reducing effective tidal volume.

Question 80: If the paramedic receives improper directions, what should they do?

Ignore them
Question them (Correct answer)
Report them
Follow them

Correct answer: Question them

If a paramedic receives directions that seem improper, unsafe, or unclear, they have a professional and ethical obligation to question them. Following improper directions could jeopardize patient safety, rescuer safety, or the success of the mission. It's crucial to seek clarification or alternative instructions rather than blindly proceeding.

Question 81: Which is the MOST common complication of prolonged bag-valve-mask ventilation without a gastric tube?

Tracheal mucosal injury
Laryngospasm
Pneumothorax
Gastric distension and aspiration risk (Correct answer)

Correct answer: Gastric distension and aspiration risk

Positive pressure from BVM ventilation frequently forces air into the stomach, causing distension that elevates the diaphragm and increases aspiration risk.
