Prepare for the Certified Medical-Surgical Registered Nurse exam with 1,000+ blueprint-aligned questions across all five MSNCB domains — weighted to the official blueprint, with clinical med-surg scenarios throughout, a dashboard that shows exactly where to focus, and a full exam simulation when you're ready.

The CMSRN certifies registered nurses in adult medical-surgical practice. The exam spans five domains — patient and care management, holistic patient care, interprofessional care, professional concepts, and nursing teamwork — with clinical med-surg content woven throughout.
Your practice mix mirrors the official MSNCB CMSRN blueprint, so you study in the same proportions the exam tests. Clinical med-surg content — cardiac, pulmonary, GI, endocrine, renal, and more — runs through every domain.
A domain dashboard shows exactly where you're losing points, so study time goes where it counts.
Full exam simulation mirrors the real CMSRN timing and conditions — no surprises on test day.
Progress syncs across all your devices instantly, so you can practice on any break.

An aPTT more than three times control with new bruising signals heparin over-anticoagulation. The priority is to stop the infusion and notify the provider (protamine sulfate is the heparin reversal agent).
Vitamin K reverses warfarin, not heparin. Increasing the rate compounds the over-anticoagulation. Continuing the infusion and waiting six hours lets active bleeding worsen.
Obtaining routine vital signs on a stable postoperative patient falls within the UAP scope of practice and is appropriate to delegate.
Teaching a newly diagnosed diabetic, assessing lung sounds, and evaluating a patient's response to a new medication are all nursing-judgment activities that must stay with the RN.
Assessment is the first phase of the nursing process; a focused respiratory and volume-status assessment provides the data that all subsequent diagnosis, planning, and intervention depend on.
Setting an outcome goal is the planning phase and cannot precede data collection. Giving the diuretic is implementation, which follows assessment, diagnosis, and planning. Writing a nursing diagnosis is the diagnosis phase, which also requires assessment data first.
Two-person bedside verification of patient identifiers against the blood product and paperwork is required before any transfusion, because misidentification is the leading cause of fatal hemolytic reactions.
Only 0.9% saline is compatible with blood; dextrose causes hemolysis. A rapid start risks missing an early reaction; the first 15 minutes are run slowly. Vital signs are needed before, at 15 minutes, and after.
A razor-thin vertical pacing spike appears immediately ahead of every complex, and each spike is followed by a wide slurred QRS with a T wave pointing opposite the terminal deflection. A spike that produces a complex is what capture means, so this tracing shows ventricular pacing with capture, and the opposite-pointing T wave is the expected pattern rather than a problem. Verifying sensing and capture, and watching the incision for infection, are the two pacemaker assessments the new nurse needs to carry forward, along with the precautions about magnets, metal detectors and overhead arm activity on the device side.
The complexes arrive at even intervals here, so nothing supports a fibrillating atrium with its unpredictable spacing. The complexes are wide and slurred rather than narrow, which is what a ventricular paced beat looks like and what separates it from a beat the patient conducted. The T wave points opposite the terminal deflection because the beat was paced, and it is not the tall pointed T on a pinched base that goes with a rising potassium.
