Certified Professional in Healthcare Quality Examination:
Advanced Mastery in Quality Improvement, Patient Safety,
Regulatory Compliance, Risk Management, and High-
Reliability Healthcare Systems
Target Audience: Experienced healthcare quality professionals, CPHQ candidates
Difficulty: Mixed (60% Advanced / 40% Hard)
Domain 1: Quality Improvement – Advanced Tools and Applications (Questions 1–40)
1. A hospital’s stroke team achieves 85% door-to-needle time ≤45 minutes but wants to reach 95%. Which tool is BEST
for identifying specific bottlenecks within the current workflow?
A) Spaghetti diagram
B) Pareto chart of delays by process step
C) Affinity diagram
D) Radar chart
Correct Answer: B
Rationale: A Pareto chart of delays per step will highlight the “vital few” process steps
causing most of the delay.
2. A QI team plans to reduce C. difficile infections. They map the patient journey from admission to discharge. Which
tool helps visualize handoffs and delays between departments?
A) Value stream map
B) Control chart
C) Scatter plot
D) Gantt chart
Correct Answer: A
Rationale: Value stream mapping includes process steps, wait times, and information
flow across departments.
3. A hospital implements a new electronic health record (EHR). Post-implementation, medication errors increase by
15%. The most appropriate QI approach is:
A) Abandon the EHR
B) Conduct a failure modes and effects analysis (FMEA) on the EHR ordering process
C) Discipline the training department
D) Extend the EHR to outpatient clinics
Correct Answer: B
Rationale: FMEA prospectively identifies and mitigates risks in a new or changed
process.
4. A quality director wants to compare post-operative infection rates across four surgical services with different
,volumes. Which chart is most appropriate?
A) Run chart
B) U-chart (standardized per unit)
C) X-bar and R chart
D) Histogram
Correct Answer: B
Rationale: U-chart (defects per unit) adjusts for different sample sizes (e.g., surgeries per
service).
5. A team uses a Kano model to prioritize patient experience improvements. A “basic need” (dissatisfier if absent) for
hospital food would be:
A) Gourmet chef
B) Meal arrives hot and on time
C) Restaurant-style menu
D) Free dessert
Correct Answer: B
Rationale: Basic needs are expected (hygiene factors); their absence causes
dissatisfaction.
6. In a Six Sigma project to reduce lab turnaround time, the team calculates a baseline DPMO of 50,000. This
corresponds to approximately which sigma level?
A) 2.0
B) 2.5
C) 3.2
D) 4.5
Correct Answer: C
Rationale: 50,000 DPMO ≈ 3.15–3.2 sigma (without 1.5 shift).
7. A hospital’s readmission reduction team plans a “rapid cycle improvement” week. The best daily structure is:
A) Plan for 6 months, then implement
B) PDSA cycles every 24–48 hours
C) One large implementation at week’s end
D) No data collection
Correct Answer: B
Rationale: Rapid cycle = multiple small PDSA cycles in short timeframes.
8. A QI team is deciding between three fall prevention interventions. They evaluate cost, feasibility, and expected
impact. The best prioritization tool is:
A) Brainstorming
B) Prioritization matrix (Pugh matrix)
C) Fishbone diagram
D) Run chart
Correct Answer: B
Rationale: Prioritization matrix scores options against weighted criteria.
, 9. A process capability analysis for ED door-to-provider time yields Cp = 0.8 and Cpk = 0.5. This indicates:
A) Process is centered but not capable
B) Process is not capable and not centered
C) Process is fully capable
D) Process is over-specified
Correct Answer: B
*Rationale: Cp<1 = incapable; Cpk<Cp = off-center.*
10. A hospital uses “Kanban” for surgical supplies. The primary QI benefit is:
A) Increased inventory
B) Just-in-time supply with reduced waste
C) Higher costs
D) Eliminating all staff training
Correct Answer: B
Rationale: Kanban is a Lean pull system to reduce overstock and waste.
11. A team presents a project using an A3 report. The “current condition” section should include:
A) Future state vision only
B) Graphical data (run chart, process map) and gap analysis
C) Only financial data
D) Individual performance reviews
Correct Answer: B
Rationale: A3 includes baseline data and visual depiction of the problem.
12. Which of the following is a balancing measure for a project to reduce length of stay (LOS)?
A) Average LOS in days
B) ED wait time for admission
C) Post-discharge mortality within 7 days
D) Number of discharge planners hired
Correct Answer: C
Rationale: Unintended consequence of shorter LOS could be higher early mortality.
13. A QI team uses a “five whys” technique and stops at the third “why” – “staff didn’t follow protocol.” The most
likely error is:
A) Asking too many whys
B) Stopping at a human behavior instead of system cause
C) Using the wrong QI model
D) Involving too many people
Correct Answer: B
Rationale: True root cause requires probing beyond individual behavior to system
factors.
14. A control chart of monthly fall rates shows 4 consecutive points near the upper control limit but within it. This
indicates:
A) Immediate special cause
