CRNI Exam Quality Improvement and Outcomes Management in Infusion Therapy — Questions and Answers
Question 1: A nurse infusion team tracks catheter-associated bloodstream infection (CLABSI) rates and compares them to national benchmarks. Which organization publishes the most widely used CLABSI benchmark data for acute-care settings?
- Centers for Disease Control and Prevention (CDC) / NHSN (Correct answer)
- Joint Commission on Accreditation of Healthcare Organizations
- Infusion Nurses Society (INS)
- American Nurses Credentialing Center (ANCC)
Correct answer: Centers for Disease Control and Prevention (CDC) / NHSN
The CDC's National Healthcare Safety Network (NHSN) is the national surveillance system that collects and publishes CLABSI rates by facility type, providing the benchmark data used to evaluate infusion program performance.
Question 2: An infusion program wants to reduce peripheral IV infiltration rates. Using the Plan-Do-Study-Act (PDSA) cycle, which step involves analyzing collected data to determine whether the change produced improvement?
- Plan
- Do
- Study (Correct answer)
- Act
Correct answer: Study
The 'Study' phase of the PDSA cycle is where data collected during the 'Do' phase are analyzed and compared against the baseline to determine whether the intervention achieved the intended improvement.
Question 3: Which infusion-specific quality indicator is most directly used to evaluate the effectiveness of a central venous access device (CVAD) care bundle?
- Phlebitis rate per 1,000 peripheral IV days
- CLABSI rate per 1,000 central-line days (Correct answer)
- Medication error rate per infusion order
- Patient satisfaction scores for IV insertion
Correct answer: CLABSI rate per 1,000 central-line days
CLABSI rate per 1,000 central-line days is the standard outcome metric tied directly to central line care bundles (hand hygiene, maximal barrier precautions, chlorhexidine skin prep, optimal site selection, and daily review). A reduction in this rate demonstrates bundle effectiveness.
Question 4: According to INS Standards of Practice, how should an infusion nurse respond when evidence-based research contradicts an existing institutional policy?
- Continue following the institutional policy until it is formally updated through governance
- Immediately implement the new evidence-based practice without notifying management
- Advocate for policy review through appropriate channels while complying with current policy (Correct answer)
- Document personal disagreement in the patient record and follow personal clinical judgment
Correct answer: Advocate for policy review through appropriate channels while complying with current policy
INS Standards require nurses to practice evidence-based care and to advocate for policy changes through appropriate organizational channels (e.g., practice councils, clinical leadership) while continuing to comply with existing policy until it is formally revised.
Question 5: A hospital's infusion team implements a phlebitis grading scale consistently across all nurses. This standardization primarily serves which quality improvement purpose?
- Reducing the cost of peripheral IV supplies
- Ensuring reliable, comparable outcome data for trend analysis (Correct answer)
- Eliminating the need for physician notification of phlebitis
- Shortening the duration of IV site assessments
Correct answer: Ensuring reliable, comparable outcome data for trend analysis
Standardizing a phlebitis grading scale (e.g., the Visual Infusion Phlebitis scale) ensures that all nurses assess and record phlebitis consistently, producing reliable, comparable data that can be trended over time to identify patterns and drive improvement initiatives.
Question 6: When calculating a CLABSI rate for a quarterly report, which formula is correct?
- (Number of CLABSIs ÷ Number of patients with central lines) × 100
- (Number of CLABSIs ÷ Number of central-line days) × 1,000 (Correct answer)
- (Number of CLABSIs ÷ Number of patient days) × 1,000
- (Number of CLABSIs ÷ Number of CVAD insertions) × 100
Correct answer: (Number of CLABSIs ÷ Number of central-line days) × 1,000
The standardized CLABSI rate formula is (number of CLABSIs ÷ total central-line days) × 1,000. Using central-line days as the denominator—rather than patients or patient days—accounts for duration of exposure and allows meaningful comparison across units and facilities.
