According to U.S. Army Medical Center of Excellence (MEDCoE), EFMB Test Control Office, “Candidates must complete 60 multiple choice questions in 1 hour 30 minutes or less.”[1]
The EFMB testing cycle evaluates medical personnel through field challenges and a formal Written Test administered by the U.S. Army Medical Center of Excellence (MEDCoE) EFMB Test Control Office. There are no centralized national testing dates. Instead, candidates test through host units. Host units must submit formal requests to test no later than 90 days prior to the anticipated test-start date for CONUS units, or 120 days prior for OCONUS units.
To be eligible to test, candidates must volunteer, obtain a commander recommendation, be qualified on their individual weapon dated within 1 year of testing, maintain current BLS certification, and not be flagged. Testing schedules, site locations, and field training requirements vary by host installation, so candidates should confirm event details with their unit EFMB test representatives.
The Written Test is executed digitally as a prerequisite prior to in-processing and/or at the EFMB site. It consists of 60 multiple-choice questions that candidates must complete in 1 hour 30 minutes or less. Passing requires answering 45 out of 60 questions correctly. While field testing events do not permit retesting, the Written Test is the only retestable event in the testing cycle.
Prepare for the EFMB - Expert Field Medical Badge exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: Which assessment method provides the MOST reliable data for EFMB professionals making critical decisions?
Answer: B. Standardized tools combined with professional observation
Explanation:
Option B is correct because pairing standardized evaluation tools with direct professional observation produces reliable, measurable findings while capturing nuanced situational context. Option A is incorrect because informal verbal feedback alone lacks structured metrics and objective verification. Option C is incorrect because social media reviews and testimonials introduce subjective bias and unverified personal claims. Option D is incorrect because single-source data from one stakeholder creates informational blind spots. The general rule is to base critical decisions on structured measurement tools corroborated by direct observation rather than isolated subjective input.
Question: What does Line 9 of the MEDEVAC request indicate?
Answer: B. NBC contamination of the casualty
Explanation:
Option B is correct because Line 9 communicates nuclear, biological, or chemical contamination status, warning flight crews and receiving facilities about hazardous exposures prior to arrival. Option A is incorrect because ambulatory patient counts fall under casualty categorization lines rather than Line 9. Option C is incorrect because security conditions at the pickup site are communicated in security reporting lines. Option D is incorrect because terrain descriptions belong to landing zone obstacle coordination. The general rule is that Line 9 identifies contamination hazards to safeguard evacuation assets and medical personnel during transport.
Question: Tranexamic acid (TXA) must be administered within how many hours of injury to be effective in trauma patients?
Answer: C. 3 hours
Explanation:
Option C is correct because tranexamic acid demonstrates efficacy when administered within 3 hours of initial traumatic injury to stabilize blood clots and limit hemorrhage. Option A is incorrect because 1 hour is within the treatment timeframe but does not mark the boundary limit for administration. Option B is incorrect because 2 hours is safe for administration but does not define the full therapeutic interval. Option D is incorrect because administration at 6 hours post-injury exceeds the therapeutic window and can worsen clinical outcomes. The general rule is to initiate antifibrinolytic treatment within 3 hours of injury.
Begin preparation by pairing official military medical doctrine with targeted question sets. Review casualty evacuation procedures through EFMB Medical Evacuation & Equipment and refresh emergency dosing protocols with EFMB Pharmacology & Medications. Continue reviewing field stabilization techniques using EFMB Medical Skills & Combat Medicine and casualty sorting scenarios with EFMB Triage & Mass Casualty Management.
Next, evaluate documentation guidelines through EFMB Documentation & Legal Standards and clinical practices in EFMB Clinical Procedures & Techniques. Reinforce safety protocols by practicing EFMB Safety & Infection Control and care workflows with EFMB Patient Assessment & Care Planning.
As test day approaches, simulate real testing conditions. The digital Written Test requires completing 60 multiple-choice questions in 1 hour 30 minutes or less, with a passing standard of 45 out of 60 questions correctly answered. Rehearse under timed constraints using the full Start Practice Test module to confirm pacing, identify knowledge gaps, and verify operational recall before testing with your host unit.
Candidates must answer 45 out of 60 questions correctly to pass the EFMB Written Test. The exam consists of 60 multiple-choice questions delivered digitally either prior to in-processing or at the EFMB site. Testers are allotted 1 hour 30 minutes or less to complete all questions. There are no partial credit allowances or alternative scoring scales.
Yes, the Written Test is the only retestable event in the entire EFMB testing cycle. While candidates who fail practical field events or physical challenges are eliminated without a retest option, policy specifically permits retesting on the digital written examination. Candidates must coordinate retake administration directly through their host unit test officials.
Candidates must be volunteers who have obtained a formal commander recommendation and are not currently flagged. Additionally, candidates must possess a current BLS certification and hold an individual weapon qualification dated within 1 year of testing. Meeting all eligibility criteria is required before candidates can be scheduled by their unit.
There are no national testing dates. Candidates test through individual host units, and requests must be submitted through the EFMB test leadership of the host unit. Host units must submit formal requests to test no later than 90 days prior to the test start for CONUS locations, or 120 days prior for OCONUS locations.
The Written Test is executed digitally as a prerequisite prior to in-processing and/or at the EFMB site under the authority of the MEDCoE EFMB Test Control Office. Candidates complete 60 multiple-choice questions within a time limit of 1 hour 30 minutes or less, needing 45 correct answers to achieve a passing evaluation.
