Exam Title: Santa Clara County Utilization Review Nurse Certification Examination:
Comprehensive Assessment of Medical Necessity Determination, Regulatory Compliance, Care
Coordination, Denials Management, and Ethical Standards in Acute, Behavioral Health, and
Post-Acute Care Settings
, 2
Target Audience: Experienced Registered Nurses seeking Utilization Review certification or
competency validation within Santa Clara County healthcare systems, including Santa Clara
Valley Medical Center, San Jose Behavioral Health, and affiliated managed care organizations.
Difficulty Level: Advanced / Mixed (combining foundational knowledge with complex clinical
reasoning and application-based scenarios)
SECTION 1: MEDICAL NECESSITY AND CLINICAL CRITERIA (Questions 1-30)
1. A utilization review nurse is evaluating a patient admitted for observation status who has
been in the hospital for 36 hours. The patient's clinical condition remains stable with no
significant changes. According to CMS guidelines, what is the most appropriate action?
A. Automatically convert the patient to inpatient status due to time elapsed
B. Continue observation status and reassess every 24 hours
C. Evaluate whether the patient meets criteria for inpatient admission under the Two-Midnight
Rule
D. Discharge the patient immediately to avoid Medicare audit penalties
-detailed answer 100% correct :- C
Rationale: Under CMS's Two-Midnight Rule, inpatient admission is appropriate when the
patient is reasonably expected to require hospital care spanning at least two midnights, and the
medical record supports that expectation. Observation status requires ongoing clinical
assessment; the UR nurse must evaluate whether the patient's condition now meets inpatient
criteria rather than relying solely on time elapsed. Simply converting based on time (A) or
discharging without clinical justification (D) are inappropriate. Reassessment every 24 hours (B)
is insufficient without applying formal criteria.
2. Which of the following best defines "medical necessity" in the context of utilization review?
A. Any treatment ordered by the attending physician
B. Services that are convenient for the patient and family
C. Health care services that are appropriate, clinically indicated, and essential for the diagnosis
or treatment of a patient's condition
D. Services that generate the highest reimbursement for the facility
-detailed answer 100% correct :- C
, 3
Rationale: Medical necessity requires that services be appropriate and clinically indicated for
the patient's specific condition. It is not determined by physician preference alone (A), patient
convenience (B), or reimbursement considerations (D). UR nurses must apply evidence-based
criteria to determine whether proposed services meet medical necessity standards.
3. A UR nurse is reviewing a chart for a patient with pneumonia who was admitted three days
ago. The patient's vital signs have normalized, and oral intake is adequate. The physician
orders continued inpatient stay for "observation." What should the UR nurse do?
A. Approve the continued stay without question
B. Request a peer-to-peer review to discuss medical necessity for continued acute care
C. Automatically deny the stay and discharge the patient
D. Document the physician's order and close the review
-detailed answer 100% correct :- B
Rationale: When clinical indicators suggest the patient no longer meets acute care criteria, the
UR nurse should initiate a peer-to-peer review or discussion with the physician to evaluate
ongoing medical necessity. The UR nurse does not have independent authority to discharge (C)
but must advocate for appropriate level of care. Approving without question (A) or passive
documentation (D) fails the UR nurse's gatekeeping responsibility.
4. InterQual criteria are used by UR nurses to:
A. Determine hospital reimbursement rates
B. Evaluate the medical necessity and appropriateness of the level of care
C. Assign ICD-10 diagnosis codes
D. Calculate patient length of stay averages
-detailed answer 100% correct :- B
Rationale: InterQual provides evidence-based criteria that help determine the right level of care
and appropriate settings, anchoring decisions to clinical facts and time-sensitive thresholds. It is
not used for reimbursement determination (A), coding (C), or statistical calculations (D), though
these may be informed by UR decisions.

5. A patient is admitted with chest pain. Cardiac enzymes are negative, EKG shows no acute
changes, and the patient is pain-free. The physician wants to keep the patient for "rule out
MI" for an additional 48 hours. Using MCG criteria, the UR nurse should:
A. Approve the stay since the physician ordered it
B. Request additional clinical justification for continued acute care
C. Immediately discharge the patient against medical advice
D. Place the patient on a 1:1 observation
-detailed answer 100% correct :- B
Rationale: When clinical findings do not support ongoing acute care, the UR nurse must seek
additional justification or recommend a lower level of care. MCG and InterQual criteria require
objective clinical evidence to support continued stay. Immediate discharge (C) exceeds the UR
nurse's authority, and approval without justification (A) violates UR standards.
6. What is the primary purpose of the Two-Midnight Rule established by CMS?
A. To limit all hospital admissions to two days maximum
B. To establish when an inpatient admission is necessary and payable under Medicare Part A
C. To require all patients to be discharged by midnight
D. To eliminate observation status entirely
-detailed answer 100% correct :- B
Rationale: The Two-Midnight Rule establishes when an inpatient admission is necessary and
payable under Medicare Part A, generally applying to cases where a hospital stay crossing two
midnights is expected. It does not limit all admissions to two days (A), require midnight
discharges (C), or eliminate observation status (D).
7. A UR nurse is reviewing a Medicare patient admitted for elective total knee replacement.
The surgery is on the Medicare Inpatient-Only List. The expected length of stay is 2 days. How
should the UR nurse classify this admission?
A. Observation status because the stay is less than two midnights
B. Inpatient admission because the procedure is on the Inpatient-Only List
C. Outpatient surgery with 23-hour observation
D. Skilled nursing facility placement
-detailed answer 100% correct :- B
