Expert Field Medical Badge (EFMB) Written Test — Questions and Answers

Question 1: When administering IV fluids in a cold environment, what precaution should the medic take?

Administer the fluid faster to prevent hypothermia
Warm the IV fluid to prevent worsening hypothermia in the casualty (Correct answer)
Use colloids instead of crystalloids in cold weather
Avoid IV fluids entirely in cold environments

Correct answer: Warm the IV fluid to prevent worsening hypothermia in the casualty

Cold IV fluids can significantly worsen hypothermia in a casualty, so fluids should be warmed using chemical warmers or insulation before and during administration.

Question 2: A casualty has a sucking chest wound. After applying a vented chest seal, the casualty deteriorates with worsening respiratory distress. What is the next step?

Apply a second chest seal over the first
Burp or remove the chest seal and reassess (Correct answer)
Administer supplemental oxygen only
Initiate CPR immediately

Correct answer: Burp or remove the chest seal and reassess

If a casualty deteriorates after a chest seal is applied, a tension pneumothorax may be developing and the seal should be burped or removed to allow air to escape.

Question 3: When a EFMB professional encounters an unexpected result during a technical procedure, the FIRST action should be to:

Continue the procedure and address it later
Report the issue without any preliminary assessment
Stop, assess the situation, and determine whether to proceed or seek guidance (Correct answer)
Repeat the procedure from the beginning immediately

Correct answer: Stop, assess the situation, and determine whether to proceed or seek guidance

Stopping to assess the situation when unexpected results occur is critical. This allows the professional to evaluate whether it is safe and appropriate to continue, and to determine if additional guidance or resources are needed.

Question 4: Which landmark is used to perform an emergency intraosseous (IO) insertion at the proximal tibia?

2 cm below the tibial tuberosity on the anteromedial surface (Correct answer)
2 cm above the medial malleolus
Directly over the tibial tuberosity
Lateral aspect of the tibial head

Correct answer: 2 cm below the tibial tuberosity on the anteromedial surface

The proximal tibial IO site is 2 cm below the tibial tuberosity on the flat anteromedial surface of the tibia, away from the growth plate.

Question 5: Which assessment method provides the MOST reliable data for EFMB professionals making critical decisions?

Informal verbal feedback alone
Standardized tools combined with professional observation (Correct answer)
Single-source data from one stakeholder
Social media reviews and testimonials

Correct answer: Standardized tools combined with professional observation

Combining standardized assessment tools with professional observation provides the most reliable and comprehensive data. Standardized tools ensure consistency and validity, while professional observation captures nuances that tools might miss.

Question 6: Which IV fluid is the preferred resuscitation fluid for hypovolemic shock in TCCC?

5% dextrose in water (D5W)
Hextend (6% hetastarch) (Correct answer)
Lactated Ringer's solution
Normal saline (0.9% NaCl)

Correct answer: Hextend (6% hetastarch)

Hextend is the preferred resuscitation fluid in TCCC for hypovolemic shock because 500 mL provides volume expansion equivalent to 2 liters of crystalloid.

Question 7: Which documentation practice BEST demonstrates regulatory compliance for EFMB certified professionals?

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

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

Organized, dated, and signed records demonstrate systematic compliance with regulatory requirements. Proper documentation serves as evidence during audits, protects against liability, and shows a pattern of consistent adherence to standards.

Question 8: In EFMB practice, what happens when regulations are updated or changed?

Previous certifications are automatically revoked
Professionals must update their knowledge and practices to meet new requirements (Correct answer)
Changes apply only to new professionals entering the field
Existing professionals are permanently grandfathered in

Correct answer: Professionals must update their knowledge and practices to meet new requirements

When regulations change, all professionals must update their knowledge and practices to comply with new requirements. While transition periods may exist, compliance with current regulations is mandatory for all practitioners regardless of when they were certified.

Question 9: Which route is preferred for administering medications when IV access cannot be established in a critical trauma casualty?

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

Correct answer: Intraosseous (IO) access

Question 11: Tranexamic acid (TXA) must be administered within how many hours of injury to be effective in trauma patients?

2 hours
6 hours
3 hours (Correct answer)
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 12: What does the acronym 'SALT' stand for in mass casualty triage?

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

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

Colloids are always preferred over crystalloids in hemorrhagic shock
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)
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 14: When establishing a patrol base during field training, the medic's primary responsibility includes:

Coordinating logistics for the entire unit
Building fortifications at the perimeter
Setting up the radio communications net
Conducting a health and welfare check of all soldiers (Correct answer)

Correct answer: Conducting a health and welfare check of all soldiers

The unit medic conducts health and welfare checks at the patrol base to identify injuries, illness, and preventive medicine issues.

Question 15: Within what time window must TXA (tranexamic acid) be administered to be effective in a trauma casualty?

At any time after injury
Within 1 hour of injury only
Within 6 hours of injury
Within 3 hours of injury (Correct answer)

Correct answer: Within 3 hours of injury

TXA must be given within 3 hours of injury; administration after 3 hours has been shown to increase mortality rather than decrease it.

Question 16: In TCCC, what does the mnemonic MARCH stand for?

Massive hemorrhage, Airway, Respiration, Casualty, Hydration
Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia/Head injury (Correct answer)
Monitor, Airway, Respirations, Compressions, Hypothermia

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

Question 21: A casualty presents with Beck's Triad (hypotension, muffled heart sounds, JVD) after a penetrating chest wound. What injury should you suspect?

Tension pneumothorax
Aortic transection
Massive hemothorax
Cardiac tamponade (Correct answer)

Correct answer: Cardiac tamponade

Beck's Triad — hypotension, muffled heart sounds, and jugular vein distension — is the classic presentation of cardiac tamponade caused by blood in the pericardial sac.

Question 22: What is the purpose of a vented (Hyfin) chest seal versus a non-vented chest seal?

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

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 23: When establishing priorities of work at a new patrol base, the medic's FIRST consideration should be:

Ensuring security is established before conducting medical assessments (Correct answer)
Setting up the aid station with all equipment unpacked
Coordinating MEDEVAC assets before anything else
Conducting sick call for any soldiers with minor complaints

Correct answer: Ensuring security is established before conducting medical assessments

Security must be established before any other work begins at a patrol base; no mission function, including medical care, is effective without security.

Question 55: What is the primary concern when treating a casualty with shock?

Administer pain medication.
Restore circulation and oxygen to vital organs (Correct answer)
Provide high doses of adrenaline.
Ensure the casualty is kept warm and hydrated.

Correct answer: Restore circulation and oxygen to vital organs

When a casualty is in shock, their body's vital organs are not receiving enough blood flow and oxygen, which can quickly lead to organ damage or failure. Restoring circulation and oxygen is paramount to prevent irreversible damage and save the casualty's life. This often involves controlling bleeding, maintaining an open airway, and supporting breathing, which are critical steps in tactical combat casualty care (TCCC).

Question 56: An unconscious casualty with no gag reflex needs airway management. What is the preferred airway adjunct in TCCC?

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

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

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

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

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

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

Question 59: Diazepam autoinjector is given to a nerve agent casualty primarily to treat which complication?

Pain from muscle cramps
Respiratory depression
Seizures caused by nerve agent toxicity (Correct answer)
Anxiety and combativeness

Correct answer: Seizures caused by nerve agent toxicity

The diazepam autoinjector (Convulsant Antidote for Nerve Agents, CANA) is used to terminate or prevent seizures that occur with severe nerve agent poisoning.

Question 60: A medic is treating a casualty for cold injuries when the casualty asks if you should rewarm a frostbitten foot if the soldier must still walk out. What is the correct answer?

Rewarm partially to the ankle level only
Rewarm only if shelter is within 1 hour
Yes, rewarm immediately regardless of circumstances
No, do not rewarm if the soldier must walk — refreezing causes far worse tissue damage (Correct answer)

Correct answer: No, do not rewarm if the soldier must walk — refreezing causes far worse tissue damage

Frostbite should NOT be rewarmed if refreezing is possible — walking on frozen tissue causes less damage than the freeze-thaw-refreeze cycle.

Question 61: When documenting assessment findings in EFMB practice, which approach is MOST appropriate?

Use technical jargon that only experts can understand
Record objective findings, measurements, and professional observations factually (Correct answer)
Include only positive findings to maintain optimism
Summarize findings verbally without written documentation

Correct answer: Record objective findings, measurements, and professional observations factually

Assessment documentation must be objective, factual, and comprehensive. Recording measurements, observations, and findings without bias ensures that the documentation is useful for decision-making and withstands scrutiny.

Question 62: What is the primary purpose of administering morphine sulfate in a combat casualty?

To increase blood pressure in shock
To treat infection at the wound site
To manage severe pain while maintaining airway reflexes (Correct answer)
To induce unconsciousness

Across one shoulder with the casualty's arm and leg hanging in front (Correct answer)
Centered across both shoulders
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 65: In a mass casualty incident, which category of patients should generally be treated LAST despite having real injuries?

Expectant
Minimal (Correct answer)
Delayed
Immediate

Correct answer: Minimal

Minimal (T3/Green) patients have minor injuries, are ambulatory, and can often self-treat, so they receive care last to preserve resources for critical casualties.

Question 66: What is the primary function of a tourniquet application during Tactical Combat Casualty Care (TCCC)?

To provide venous access for IV fluids
To control life-threatening extremity hemorrhage (Correct answer)
To immobilize a fractured extremity
To reduce swelling after blunt trauma

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 67: Which litter carry technique is best suited for moving a casualty through narrow corridors or confined spaces?

SKED litter drag (Correct answer)
Two-person litter carry
Fireman's carry
Four-person litter carry

Correct answer: SKED litter drag

The SKED litter allows a casualty to be dragged through narrow corridors, tunnels, or rubble because its flexible design conforms to tight spaces.
