Quality Control & Assurance Flashcards

A CNS is tasked with reducing CAUTI rates on a 30-bed medical unit. The current rate is 3.2 per 1,000 catheter-days versus a national benchmark of 1.0. Which initial QI strategy is most appropriate?

Answer: Conduct a gap analysis of current practices against CDC/HICPAC CAUTI prevention guidelines

Gap analysis against evidence-based guidelines identifies specific practice deficiencies before intervention selection — this prevents implementing solutions without understanding the problem.

A CNS is using Statistical Process Control (SPC) to monitor a medication reconciliation process. After implementing a new protocol, the control chart shows 8 consecutive data points below the centerline. What does this indicate?

Answer: Special cause variation suggesting the intervention has had a significant positive effect

Eight consecutive points below the centerline is a Western Electric SPC rule violation indicating special cause variation — a non-random signal suggesting the intervention has changed the process.

The CNS is conducting a root cause analysis (RCA) following a patient safety event. Which tool best helps identify systemic contributing factors visually?

Answer: Fishbone diagram (Ishikawa/cause-and-effect diagram)

The fishbone diagram visually maps cause-and-effect relationships across multiple categories (people, process, equipment, environment, management, materials), identifying systemic contributing factors.

A CNS reviewing ventilator-associated event (VAE) data notices that rates vary significantly between day and night shifts. What is the most likely explanation and appropriate response?

Answer: Variation in adherence to VAE prevention bundle elements between shifts suggests a consistency of care problem requiring targeted education and monitoring

Significant shift-related variation typically reflects inconsistent bundle adherence — this requires investigation of specific practices on each shift and targeted educational intervention.

A CNS is implementing Lean methodology to improve patient throughput in a medical-surgical unit. Which Lean tool best identifies waste in the current patient discharge process?

Answer: Value Stream Map (VSM) documenting every step, wait time, and information flow in the discharge process

Value Stream Mapping visualizes every step, wait, and handoff in a process, explicitly identifying non-value-added steps (waste) for elimination.

Which national database provides benchmarked nursing-sensitive quality indicators specifically for acute care settings, allowing CNS comparison of unit performance to national peer groups?

Answer: National Database of Nursing Quality Indicators (NDNQI)

NDNQI (now Press Ganey) provides nursing-sensitive quality indicators benchmarked by unit type and patient volume, allowing CNSs to compare unit performance to national peer groups.
