Nurses considering certification through the Medical-Surgical Nursing Certification Board (MSNCB) need to distinguish CMSRN requirements from CAVRN requirements. This page brings together eligibility, exam format, delivery options, and scoring facts, alongside free practice sets organized by nursing topic. Use the worked explanations to examine your reasoning and the study plan to choose what to review next. Our practice questions are written with AI tools and are not real exam questions.

MSNCB Exam at a Glance

What changed for MSNCB in 2026

• Oct 26, 2026: Delivery (CMSRN) changed to Year-round at Pearson VUE test centers or online via OnVUE (previously Pearson VUE test centers or OnVUE online proctoring).^[4]
• Sep 30, 2026: September 30, 2026, was the last day to submit a CAVRN application and still take the current exam. Applications from October 1 onward go to the beta test.^[1]

What the MSNCB is and how it works

According to Medical-Surgical Nursing Certification Board, “The CAVRN exam has 120 multiple choice questions, and 100 of the questions count toward your score.”^[1]

MSNCB offers CMSRN certification for medical-surgical nursing and CAVRN certification for virtual acute-care nursing. Their eligibility requirements and exam formats differ, so check the requirements for your intended credential before applying.

CMSRN eligibility requires a current, unencumbered RN license from the US, its territories, or Canada, plus 2,000 medical-surgical practice hours within the past 3 years. Practice may be as a clinical nurse, manager, or educator. CAVRN requires a current, unencumbered US RN license and 1,000 virtual acute-care practice hours within the past 2 years. MSNCB’s certification pages are the official sources for these requirements.

The CMSRN exam has 150 multiple-choice questions, with 125 scored, and a 3-hour time limit. It is offered year-round, excluding holidays, at Pearson VUE test centers or through OnVUE remote proctoring. You have 90 days to test after receiving Authorization to Test. CAVRN has 120 multiple-choice questions, with 100 scored, and offers Pearson VUE test center or OnVUE delivery.

Both exams require a standard score of 95. MSNCB describes this as about 71% correct for CMSRN and about 83% for CAVRN. Consult the relevant MSNCB certification page and handbook when planning your application; the scoring percentages are approximate.

MSNCB content outline and where to practise each area

Worked examples: how to reason through MSNCB 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: When documenting assessment findings in MSNCB practice, which approach is MOST appropriate?

1. Include only positive findings to maintain optimism
2. Record objective findings, measurements, and professional observations factually
3. Use technical jargon that only experts can understand
4. Summarize findings verbally without written documentation

Answer: B. Record objective findings, measurements, and professional observations factually

Explanation:

Option B is correct: objective findings, measurements, and factual professional observations give the care team a usable record of the assessment. The documentation should describe what was found without adding unsupported interpretations. Option A is wrong because recording only positive findings leaves out information that may affect care; maintaining optimism is not a reason to omit findings. Option C is wrong because language that readers cannot understand makes the record less useful. Option D is wrong because a verbal summary does not replace written documentation. Remember: document findings factually and clearly, including relevant findings that do not fit an encouraging picture.

Example 2

Question: Which sign/symptom is MOST specific to a pheochromocytoma?

1. Persistent hypertension unresponsive to medication
2. Episodic hypertension with headache, diaphoresis, and palpitations
3. Orthostatic hypotension with tachycardia
4. Hypertension with bilateral leg edema

Answer: B. Episodic hypertension with headache, diaphoresis, and palpitations

Explanation:

Option B is correct: episodic hypertension accompanied by headache, diaphoresis, and palpitations matches the characteristic pattern of catecholamine surges described in the question’s explanation. The combination and episodic timing make this the best answer among the choices. Option A describes persistent hypertension without the associated symptom pattern, so it is less specific. Option C describes a blood-pressure drop on standing with tachycardia, rather than the hypertensive episodes in the characteristic presentation. Option D pairs hypertension with leg edema and does not match that pattern. Remember: compare the whole symptom cluster and its timing, rather than selecting an answer solely because it mentions hypertension.

Example 3

Question: Why is it necessary to monitor a patient’s response to medication?

1. To determine if the medication is providing immediate relief
2. To evaluate effectiveness, identify side effects, and adjust treatment as needed
3. To limit the need for patient education
4. To reduce the amount of medication prescribed

Answer: B. To evaluate effectiveness, identify side effects, and adjust treatment as needed

Explanation:

Option B is correct: monitoring establishes whether a medication is producing its intended effect and helps identify side effects that may require a change in the treatment plan. Option A is too narrow because immediate relief is not the only outcome to assess; ongoing effectiveness and unwanted effects also matter. Option C is wrong because observing a response does not remove the need for patient education. Option D is wrong because reducing the amount prescribed is not the purpose of monitoring; any adjustment depends on the findings. Remember: assess both benefit and harm, and use the patient’s response to inform ongoing treatment decisions.

How to use these practice tests

Start with the official MSNCB certification page and handbook for your intended credential. Check eligibility and delivery requirements before planning practice. Keep the official content outline beside your study notes; the topic links here are practice choices, not a replacement for that outline or evidence that every domain is fully covered.

Begin with Patient Assessment & Care Planning. Answer before reading explanations, then record the reasoning behind missed answers and guesses. Identify whether the difficulty was recognizing a finding, choosing a priority, or distinguishing plausible options.

Choose follow-up practice from those notes. Use Fluid & Electrolyte Balance, Respiratory Care, or Pharmacology & Medication Management where relevant. Explain why each alternative is less appropriate before checking the rationale. Verify uncertain clinical points against your nursing references.

Return to missed topics and check whether you can explain the rule without recalling the answer wording. Before test day, revisit the official scheduling instructions. For CMSRN, plan around the 3-hour exam and your 90-day testing period.
