How many questions do I need to get right?
You need a standard scaled score of 95 to pass. This means you must answer approximately 71% of the 125 scored items correctly.
What makes the test difficult?
The test challenges your clinical judgment across multiple systems and situations. You must apply medical-surgical knowledge to complex patient scenarios rather than simply recalling basic facts.
Which section of the test is the largest?
Patient/Care Management is the heaviest domain. It makes up 32% of your test, which equals 40 items. You should spend the majority of your study time here.
What does the Nursing Teamwork and Collaboration section cover?
This domain accounts for 21% of the test, giving you 26 items. It tests your ability to delegate, communicate, and coordinate care with other nursing staff. For specific task lists, check the official MSNCB candidate handbook.
How heavily is Interprofessional Care tested?
Elements of Interprofessional Care makes up 17% of your score. You will see 21 items focused on how you interact with physicians, pharmacists, therapists, and other healthcare disciplines.
What should I know for the Holistic Patient Care domain?
You will face 19 items, or 15% of the test, in this area. Expect questions on cultural competence, end-of-life care, and patient education. Review the certifying body's guidelines for a complete breakdown of these topics.
Are Professional Concepts a big part of the score?
Professional Concepts also make up 15% of the test, totaling 19 items. This section evaluates your grasp of ethics, legal issues, and evidence-based practice.
How many total questions are on the test?
There are 125 scored questions. You may also see unscored pretest questions mixed in. The exact total number of items administered during your session is outlined in the current MSNCB certification manual.
What is the best way to prepare for the difficulty level?
Consistent testing is the most effective strategy. We offer over 4100 practice questions to help you build stamina and identify your weak areas before test day.
What happens if I fail?
You can retake the test if you do not achieve the required score of 95. For mandatory waiting periods and retesting fees, consult the official medical-surgical nursing test documentation.

Judge the difficulty yourself

These are three CMSRN practice questions at exam difficulty. See where you land. The app has 5,200+, timed and scored.

Question 1

A postoperative patient needs heparin injections. The unit has prefilled syringes ($1.80/dose) and vials requiring nurse-drawn doses ($0.30/dose). The nurse has 12 high-acuity patients. Which method optimizes fiscal and clinical efficiency?

β–Έ Why A is the answer

High patient acuity increases error risks with vial draws (discriminating cue: 12 high-acuity patients). Prefilled syringes enhance safety despite higher cost, aligning with Joint Commission med safety goals. Option B risks dosage inaccuracies and contamination. Options C/D create inconsistent practices. Safety justifies added expense when cognitive load threatens precision.

Question 2

A nurse receives a telemedicine call from a COPD patient using home oxygen. They report increased dyspnea when walking to the bathroom but normal O2 saturations at rest. Which response prioritizes safety?

β–Έ Why A is the answer

Stable rest saturations and isolated exertional dyspnea allow conservative management first. Option A promotes self-management per GOLD guidelines. Option B is premature without fever or resting desaturation. Option C risks oxygen-induced hypercapnia without provider orders. Option D delays non-urgent intervention. Cues (normal rest sats, no systemic symptoms) support monitored self-care.

Question 3

A 68-year-old patient with severe COPD and obstructive sleep apnea is receiving morphine PCA after abdominal surgery. Which assessment parameter requires the MOST frequent monitoring during the first 24 hours postoperatively?

β–Έ Why B is the answer

Patients with COPD and sleep apnea have high opioid-induced respiratory depression risk. Continuous SpO2 detects hypoxemia early, and hourly respiratory rate identifies bradypnea. While pain scores (C) are important, respiratory status takes priority. Blood pressure (A) is less critical than airway compromise. Sedation scales (D) are essential but don't replace respiratory monitoring; every-shift checks are insufficient. CMSRN guidelines emphasize continuous respiratory monitoring for high-risk patients on IV opioids.
