If you care for adult patients on a medical-surgical unit, you already juggle more conditions, medications, and priorities in a single shift than most people see in a week. The Medical-Surgical Nursing Certification (MEDSURG-BC™) from the American Nurses Credentialing Center (ANCC) recognizes that expertise. Because med-surg covers nearly every body system, the exam can feel impossibly broad at first. The good news is that ANCC publishes exactly how the test is built, and a plan organized around that blueprint makes passing on your first try a realistic goal.

In this guide, we’ll walk you through the exam format, the three content domains and how many questions each contributes, the official resources worth downloading, and the questions candidates ask most often.

What Is the ANCC MEDSURG-BC Exam?

The MEDSURG-BC is ANCC’s board certification for registered nurses (RNs) who practice in medical-surgical nursing. When you pass, you earn the right to use the credential Medical-Surgical Nurse, Board Certified (MEDSURG-BC) for a five-year certification period.

The exam is a competency-based test of how you apply the nursing process to adult patients with acute and chronic medical and surgical conditions. It is not a memorization test of rare diseases. Most questions describe a patient situation and ask you to choose a priority assessment, the safest intervention, the best teaching approach, or the most appropriate professional response.

What Is the ANCC MEDSURG-BC Exam Format?

Here is the exam at a glance, based on the ANCC MEDSURG-BC certification page and the ANCC Certification Handbook:

  • Questions: 150 questions.
  • Scored vs. unscored: 125 scored questions plus 25 unscored pretest questions. The pretest items are mixed in and look like every other question, so treat each one as if it counts.
  • Time: 3 hours to answer all 150 questions, per the MEDSURG-BC certification page. Your total appointment runs longer to allow for check-in, instructions, and a short computer tutorial.
  • Question format: Multiple-choice, with most items written as clinical scenarios.
  • Delivery: Computer-based testing at Prometric test centers year-round. After ANCC approves your application, you have 120 days to schedule and sit for the exam.
  • Passing score: A scaled score of 350 or higher on a scale up to 500.
  • Results: You view your results online through Prometric’s score report portal after testing, and ANCC receives your results within 24 to 48 hours. Your certificate arrives by mail a few weeks after you pass.

With 180 minutes for 150 questions, you have about 72 seconds per question. That is enough time if you read stems efficiently, but longer scenarios with lab values and medication lists can slow you down if you reread them.

What Content Outline Does the MEDSURG-BC Exam Use?

The current exam follows the MEDSURG-BC Test Content Outline, effective September 10, 2024. The outline divides the 125 scored questions into three domains:

  • Domain I, Assessment and Diagnosis: 49 questions (39%)
  • Domain II, Planning, Implementation, and Evaluation: 50 questions (40%)
  • Domain III, Professional Role: 26 questions (21%)

Notice that the outline is organized by the nursing process, not by body system. Cardiac, respiratory, renal, gastrointestinal, endocrine, neurologic, and musculoskeletal conditions all show up, but they are tested through the lens of what you assess, what you do, and how you evaluate the result.

Domain I: Assessment and Diagnosis (39%)

This domain covers gathering and interpreting data, then deciding the patient’s most important problem. It is where your clinical recognition skills get tested.

  • Health history collection.
  • Physical assessment, including vital signs, disease processes, review of systems, and activities of daily living.
  • Psychosocial assessment, including developmental stages, suicide risk, abuse, and substance use disorders.
  • Cognitive assessment, including neurologic status, developmental age, and impairment.
  • Diagnostic and laboratory testing, including patient preparation, response to abnormal values, and medication considerations.
  • Nursing diagnosis identification and prioritization.
  • Knowledge of fluids and electrolytes, including imbalances, disease-related changes, and blood products.

What questions look like: You might see a patient with a potassium of 6.1 mEq/L and be asked which assessment finding is most concerning, or a postoperative patient with new confusion and asked what to assess first. Know normal lab ranges cold so you can spot the abnormal value quickly.

Domain II: Planning, Implementation, and Evaluation (40%)

The largest domain covers what you do with your assessment: planning care, intervening safely, teaching, and checking whether it worked.

  • Nursing care planning, including interventions, modifications, and outcomes.
  • Postoperative complication prevention and management, such as bleeding, infection, and emboli.
  • Patient teaching, including learning preferences, barriers, and evaluation of learning.
  • Education topics such as self-management, acute and chronic conditions, and population-specific needs.
  • Patient safety measures, including screening tools, infection prevention, restraints, and medical equipment.
  • Non-pharmacologic treatments, such as complementary and alternative therapies and diversional activities.
  • Medication interactions and adverse effects, including pain management, polypharmacy, drug-drug, and food-drug interactions.
  • Health and wellness promotion, such as screenings, vaccinations, and healthy lifestyle changes.

Study tip: Expect “first” and “priority” questions about postoperative complications like pulmonary embolism, hemorrhage, and wound dehiscence. Also review high-alert medications (anticoagulants, insulin, opioids) and how you would confirm that teaching was effective, such as with the teach-back method.

Domain III: Professional Role (21%)

This domain tests how you practice as a professional nurse beyond direct tasks: how you communicate, collaborate, advocate, and use evidence.

  • Therapeutic communication, including patient- and family-centered care and cultural competence.
  • Interdisciplinary healthcare team collaboration, including delegation and consults.
  • Nursing ethics, including advocacy.
  • Evidence-based practice, including education and supporting materials.

What questions look like: Which task can be delegated to unlicensed assistive personnel, how to respond when a patient’s family disagrees with the care plan, or how to handle a unit practice that conflicts with current evidence. Remember that an RN cannot delegate assessment, initial teaching, or evaluation.

How Should You Use the MEDSURG-BC Blueprint to Build a Study Plan?

Domains I and II together account for 99 of the 125 scored questions, so most of your time belongs there. Still, Domain III’s 26 questions are too many to leave to chance, and they are often where experienced bedside nurses lose points.

  1. Take a mixed baseline. Answer a set of questions across all three domains before you start reviewing so you know where you actually stand.
  2. Map each miss to an outline statement. Tag every wrong answer with a line from the outline, such as “fluids and electrolytes” or “delegation,” instead of a vague label like “cardiac.”
  3. Weight your time. Spend roughly 40% of your review on Domain II, 40% on Domain I, and 20% on Domain III, then shift time toward whichever statements you miss most.
  4. Study across body systems. Rotate systems within each domain so you practice assessing, intervening, and teaching for many conditions, not just the ones on your unit.
  5. Finish with timed, mixed practice. In the final weeks, practice at exam pace and review every explanation, including the questions you got right.

Frequently Asked Questions About the ANCC MEDSURG-BC Exam

What score do I need to pass the MEDSURG-BC?
You need a scaled score of at least 350 out of 500. Scaled scoring accounts for small differences in difficulty between exam forms, so there is no fixed number of questions you must answer correctly.

What is the MEDSURG-BC pass rate?
According to ANCC’s 2025 certification data, the first-time pass rate for the Medical-Surgical Nursing exam was 71%. Most candidates pass, but roughly three in ten first-time testers do not, so a structured plan is worth the effort.

What happens if I don’t pass?
You can retest 60 calendar days after your last attempt, and you may test no more than three times in any 12-month period. A new application and fee are required.
