EFMB Practice Test

This page provides practice questions and testing details for candidates preparing for the EFMB Written Test. Testing is open to military personnel who volunteer, receive a commander recommendation, qualify on their individual weapon dated within 1 year of testing, possess current BLS certification, and are not flagged. Use these practice resources alongside official military publications to prepare for testing administered digitally through your host unit.

What the EFMB is and how it works

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.

Worked examples: how to reason through EFMB questions

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.

Example 1

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

1. Informal verbal feedback alone
2. Standardized tools combined with professional observation
3. Social media reviews and testimonials
4. Single-source data from one stakeholder

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.

Example 2

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

1. Number of ambulatory patients
2. NBC contamination of the casualty
3. Security at the pickup zone
4. Terrain description of the landing zone

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.

Example 3

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

1. 1 hour
2. 2 hours
3. 3 hours
4. 6 hours

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.

How to use these practice tests

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.
