Correct answer: To control life-threatening extremity hemorrhage

Tourniquets are applied to control life-threatening hemorrhage from extremity wounds when direct pressure alone is insufficient to stop bleeding.

Question 70: What is the primary purpose of the hypothermia prevention bundle in TCCC?

Improve wound visualization
Prevent the lethal triad of hypothermia, acidosis, and coagulopathy (Correct answer)
Reduce pain perception
Provide cushioning for fractures

Correct answer: Prevent the lethal triad of hypothermia, acidosis, and coagulopathy

The hypothermia prevention bundle directly combats the 'lethal triad,' which worsens bleeding and shock outcomes in trauma.

Question 71: What is the purpose of a vented (Hyfin) chest seal versus a non-vented chest seal?

Vented seals allow air to escape preventing tension pneumothorax; non-vented seals seal all airflow (Correct answer)
Vented seals are used on exit wounds; non-vented on entry wounds
Vented seals are used for abdominal wounds; non-vented for chest wounds
There is no functional difference between the two types

Correct answer: Vented seals allow air to escape preventing tension pneumothorax; non-vented seals seal all airflow

Vented chest seals have a one-way valve that allows air to exit the chest cavity on exhalation, preventing tension pneumothorax, while non-vented seals create a complete occlusion.

Question 72: Which personal protective equipment (PPE) principle applies to ALL EFMB certified professionals regardless of their specific role?

PPE is only necessary during formal inspections
Any PPE will provide adequate protection
PPE must be properly fitted, maintained, and replaced as needed (Correct answer)
PPE is optional if experienced in the field

Correct answer: PPE must be properly fitted, maintained, and replaced as needed

Regardless of experience level or specific role, PPE must be properly fitted to the individual, regularly maintained in good condition, and replaced when worn or damaged. Improperly fitted or degraded PPE can provide a false sense of security.

Question 73: Which of the following is an absolute contraindication to using a nasopharyngeal airway?

Patient is semi-conscious with intact gag reflex
Patient is in respiratory distress
Patient has a bloody nose from trauma
Suspected mid-face fracture or basilar skull fracture (Correct answer)

Correct answer: Suspected mid-face fracture or basilar skull fracture

Suspected basilar skull or mid-face fractures are contraindications for NPA because the tube could inadvertently enter the cranial vault.

Question 74: In the START triage system, what respiration rate range classifies a patient as 'Immediate'?

Less than 8 or greater than 28 per minute
Less than 12 or greater than 20 per minute
Less than 10 or greater than 30 per minute (Correct answer)
Less than 6 or greater than 24 per minute

Correct answer: Less than 10 or greater than 30 per minute

START triage labels a patient Immediate if respirations are absent after airway repositioning, fewer than 10, or more than 30 breaths per minute.

Question 75: What is the correct method for packaging a casualty for MEDEVAC transport in cold weather?

Elevate the casualty's legs only
Wet the casualty's clothing to prevent overheating during transport
Place the casualty in a hypothermia prevention kit or wrap in a space blanket before transport (Correct answer)
Leave the casualty exposed so the crew can assess injuries on arrival

Correct answer: Place the casualty in a hypothermia prevention kit or wrap in a space blanket before transport

Casualties must be packaged in a hypothermia prevention kit (space blanket, heat-reflective materials) before MEDEVAC transport to prevent or treat hypothermia during flight.

Question 76: What does CASEVAC differ from MEDEVAC in terms of aircraft and personnel?

There is no difference; the terms are interchangeable
CASEVAC is only used for mass casualty events; MEDEVAC is for individuals
CASEVAC uses non-medical aircraft or vehicles without dedicated medical personnel; MEDEVAC uses dedicated medical assets (Correct answer)
CASEVAC uses dedicated medical helicopters with medics onboard; MEDEVAC uses non-medical aircraft

Correct answer: CASEVAC uses non-medical aircraft or vehicles without dedicated medical personnel; MEDEVAC uses dedicated medical assets

CASEVAC (Casualty Evacuation) uses non-dedicated, non-medical vehicles or aircraft with no guaranteed medical personnel, while MEDEVAC uses dedicated medical assets with trained medical crew.

Question 77: Which factor MOST significantly affects the quality of technical outcomes in EFMB practice?

The practitioner's training, preparation, and attention to detail (Correct answer)
The speed at which procedures are completed
The brand of equipment being used
The time of day the procedure is performed

Correct answer: The practitioner's training, preparation, and attention to detail

The quality of technical outcomes depends primarily on the practitioner's level of training, thorough preparation, and careful attention to detail. While equipment matters, the professional's competence is the most significant factor.

Question 78: When treating a heat stroke casualty in the field, what cooling method is most effective?

Fanning the casualty without water application
Oral hydration with cool water
Applying ice packs to the neck only
Cold water immersion or wet sheet evaporative cooling (Correct answer)

Correct answer: Cold water immersion or wet sheet evaporative cooling

Cold water immersion or wet sheet evaporative cooling is most effective for rapidly reducing core temperature in heat stroke.

Question 79: What is the recommended IV fluid rate for a conscious hemorrhagic shock patient to achieve hypotensive resuscitation?

Infuse at maximum rate regardless of blood pressure
Infuse to achieve a systolic blood pressure of 110 mmHg
Infuse to restore normal blood pressure (120/80 mmHg)
Infuse to achieve a systolic blood pressure of 80–90 mmHg (Correct answer)

Correct answer: Infuse to achieve a systolic blood pressure of 80–90 mmHg

Hypotensive resuscitation targets a systolic blood pressure of 80–90 mmHg in hemorrhagic shock to maintain perfusion while minimizing clot disruption.

Question 80: What is the correct procedure when applying a combat application tourniquet (CAT) to a limb?

Apply directly over a joint for maximum compression
Apply at the mid-shaft of the limb and leave slack
Apply below the wound to avoid nerve damage
Apply 2–3 inches above the wound over clothing if needed, then tighten until bleeding stops (Correct answer)

Correct answer: Apply 2–3 inches above the wound over clothing if needed, then tighten until bleeding stops

The CAT is applied 2–3 inches proximal (above) the wound, tightened until bleeding stops, and the time of application is marked on the tourniquet and the casualty's forehead.

Question 81: Which documentation practice BEST demonstrates regulatory compliance for EFMB certified professionals?

Filing documents only when audited
Relying on memory for routine procedures
Maintaining organized, dated, and signed records of all activities, training, and incidents (Correct answer)
Keeping informal handwritten notes

Correct answer: Maintaining organized, dated, and signed records of all activities, training, and incidents

Question 82: What does Line 9 of the MEDEVAC request indicate?

Terrain description of the landing zone
Number of ambulatory patients
NBC contamination of the casualty (Correct answer)
Security at the pickup zone

Correct answer: NBC contamination of the casualty

Line 9 of the MEDEVAC request describes nuclear, biological, or chemical (NBC) contamination status of the patient, which affects how the receiving aircraft and facility will handle the casualty.

Question 83: Which of the following BEST exemplifies 'mission command' leadership philosophy as it applies to a combat medic?

Following only explicit orders and taking no independent action
Centralizing all medical decisions at the battalion surgeon level
Requesting permission from leadership before treating any casualty
Understanding commander's intent and exercising disciplined initiative to accomplish the mission (Correct answer)

Correct answer: Understanding commander's intent and exercising disciplined initiative to accomplish the mission

Mission command empowers subordinates to exercise initiative within the commander's intent when communications fail or situations evolve beyond explicit orders.

Question 84: When a EFMB professional identifies a potential regulatory violation, the CORRECT first step is to:

Document the violation and report it through proper channels (Correct answer)
Discuss it casually with coworkers
Wait to see if it resolves on its own
Address it only if directly affected

Correct answer: Document the violation and report it through proper channels

Question 85: In an austere field environment, what is the most reliable indicator that a soldier is developing dehydration?

Complaint of thirst
Increased heart rate alone
Body weight loss of 2% or more combined with dark urine (Correct answer)
Decreased appetite

Correct answer: Body weight loss of 2% or more combined with dark urine

A body weight loss of 2% or more combined with dark-colored urine is the most reliable field indicator of clinically significant dehydration.

Question 86: During a night land navigation course, a soldier uses a lensatic compass. What technique ensures accurate azimuth maintenance while moving through dense terrain?

Use terrain association only
Shoot an azimuth every 500 meters
Travel in a straight line regardless of obstacles
Identify a visible landmark on the azimuth before moving (Correct answer)

Correct answer: Identify a visible landmark on the azimuth before moving

Identifying an intermediate landmark (aiming off) on the desired azimuth before moving prevents deviation when navigating around obstacles.

Question 87: During initial triage of a mass casualty event, what should the triage officer do FIRST?

Begin treating the most severely injured patient
Survey the scene and estimate the number of casualties (Correct answer)
Establish radio communication with battalion
Request immediate medevac for all casualties

Correct answer: Survey the scene and estimate the number of casualties

Surveying the scene and counting casualties establishes situational awareness so resources can be allocated effectively before any individual treatment begins.

Question 88: How should a hypothermic combat casualty be managed in Tactical Evacuation Care (TACEVAC)?

Keep the casualty sitting upright and exposed to air
Remove wet clothing, apply heat packs to the axillae and groin, cover with a hypothermia wrap (Correct answer)
Administer cold IV fluids slowly to stabilize core temperature
Immerse in warm water if available

Correct answer: Remove wet clothing, apply heat packs to the axillae and groin, cover with a hypothermia wrap

Preventing and treating hypothermia involves removing wet clothing, applying chemical heat packs to high-blood-flow areas, and wrapping the casualty in an insulating layer.

Question 89: Which IV fluid is considered the first-line resuscitation fluid for hemorrhagic shock in the field?

Lactated Ringer's solution (Correct answer)
Normal saline (0.9% NaCl)
Sterile water for injection
Dextrose 5% in water (D5W)

Correct answer: Lactated Ringer's solution

Lactated Ringer's solution closely mimics the electrolyte composition of plasma and is preferred over normal saline for hemorrhagic shock resuscitation.

Question 90: When conducting a risk assessment for EFMB operations, which factor should receive the HIGHEST priority?

Convenience for daily operations
Time required for safety training
Cost of implementing safety measures
Probability and severity of potential harm (Correct answer)

Correct answer: Probability and severity of potential harm

The probability and severity of potential harm are the primary factors in risk assessment. While cost and convenience are considerations, they should never override the assessment of how likely an incident is and how severe its consequences could be.

Question 91: During a 3-day field exercise, a soldier complains of weakness, nausea, headache, and confusion after drinking large amounts of water. Serum sodium is likely:

Low (hyponatremia) (Correct answer)
Unaffected by water intake
Elevated (hypernatremia)
Normal

Correct answer: Low (hyponatremia)

Drinking excessive plain water without electrolyte replacement dilutes serum sodium, causing hyponatremia with these neurological symptoms.

Question 92: When using a one-handed carry (fireman's carry) to move a casualty, where should the casualty's weight be distributed on the rescuer?

Centered across both shoulders
Across one shoulder with the casualty's arm and leg hanging in front (Correct answer)
Dragged by both arms from behind
Across the rescuer's back with arms wrapped around the neck

Correct answer: Across one shoulder with the casualty's arm and leg hanging in front

In the fireman's carry, the casualty is draped across one shoulder so their torso rests on the rescuer's shoulder with one arm and one leg hanging in front for balance.

Question 93: What is the primary difference between a crystalloid and a colloid IV fluid?

Crystalloids contain large protein molecules; colloids contain small salt ions
Crystalloids contain small ions that pass through capillaries; colloids contain large molecules that stay in vessels (Correct answer)
Colloids are always preferred over crystalloids in hemorrhagic shock
Crystalloids are given faster than colloids in all situations

Correct answer: Crystalloids contain small ions that pass through capillaries; colloids contain large molecules that stay in vessels

Crystalloids (like normal saline) contain small ions that freely cross capillary membranes, while colloids (like albumin) contain large molecules that remain in the vascular space longer.

Question 94: Which route is preferred for administering medications when IV access cannot be established in a critical trauma casualty?

Subcutaneous injection
Rectal administration
Intramuscular injection into the deltoid
Intraosseous (IO) access (Correct answer)

Correct answer: Intraosseous (IO) access

Intraosseous (IO) access provides rapid, reliable vascular access when IV cannot be established and can deliver medications and fluids at rates comparable to IV.

Question 95: Which regulatory requirement is UNIVERSAL across all Expert Field Medical Badge practice settings?

Working exclusively during business hours
Limiting services to local jurisdictions only
Maintaining current certification and meeting continuing education requirements (Correct answer)
Using specific proprietary software systems

Correct answer: Maintaining current certification and meeting continuing education requirements

Question 96: Tranexamic acid (TXA) must be administered within how many hours of injury to be effective in trauma patients?

6 hours
3 hours (Correct answer)
2 hours
1 hour

Correct answer: 3 hours

TXA is most effective when given within 3 hours of injury; after this window, it may actually increase mortality in trauma patients.

Question 97: What does the acronym 'SALT' stand for in mass casualty triage?

Sort, Analyze, Locate, Treat
Stabilize, Administer, Locate, Transfer
Survey, Assess, Limit, Transfer
Sort, Assess, Lifesaving interventions, Treatment/Transport (Correct answer)

Correct answer: Sort, Assess, Lifesaving interventions, Treatment/Transport

SALT stands for Sort, Assess, Lifesaving interventions, Treatment/Transport — the sequential steps of this triage method.

Question 98: An unconscious casualty with no gag reflex needs airway management. What is the preferred airway adjunct in TCCC?

Endotracheal intubation
Nasopharyngeal airway (NPA) (Correct answer)
Surgical cricothyrotomy
Oropharyngeal airway (OPA)

Correct answer: Nasopharyngeal airway (NPA)

The NPA is preferred in TCCC because it can be used in semi-conscious patients and doesn't require the patient to be fully unconscious, reducing aspiration risk.

Question 99: What minimum urine output color indicates adequate hydration during field operations?

Dark yellow (apple juice color)
Clear/colorless
Pale yellow (lemonade color) (Correct answer)
Orange

Correct answer: Pale yellow (lemonade color)

Pale yellow urine (lemonade color) indicates adequate hydration; clear urine may indicate overhydration while dark urine signals dehydration.

Question 100: In a MEDEVAC request, Line 3 describes the number and precedence of patients. What is the order of precedence from most to least urgent?

Urgent, Priority, Routine, Convenience
Urgent, Urgent Surgical, Priority, Routine, Convenience (Correct answer)
Priority, Urgent, Routine, Convenience
Immediate, Delayed, Minimal, Expectant

Correct answer: Urgent, Urgent Surgical, Priority, Routine, Convenience

The MEDEVAC precedence categories are Urgent (2 hours), Urgent Surgical (2 hours with surgery needed), Priority (4 hours), Routine (24 hours), and Convenience.
