1. A quality manager reviews a control chart of monthly patient-fall rates and notices that the last eight plotted points all fall below the centerline, even though every point stays between the upper and lower control limits. How should the manager interpret this pattern?
AA special-cause shift has occurred and needs investigation
BCommon-cause variation is present and action is unwarranted
CThe process is out of control because a point exceeds a limit
DThe measurement system is unreliable and needs recalibration
Correct: A special-cause shift has occurred and needs investigation.
Rationale

A run of eight or more consecutive points on one side of the centerline is a recognized run-rule violation signaling non-random, special-cause variation — a sustained shift. Staying within the control limits does not mean the process is in control; the run itself is the signal and warrants investigating what changed.

Why the other options are wrong

Calling it common-cause variation misreads a non-random run as ordinary noise. Claiming a point exceeds a limit contradicts the described pattern. Blaming the measurement system invents a problem the chart gives no evidence for.

2. A team completes a failure mode and effects analysis on a medication process and rates each failure mode for severity, occurrence, and detectability: wrong-dose entry scores 5, 6, and 6; mislabeled syringe scores 8, 3, and 4; omitted allergy check scores 9, 2, and 5; and delayed administration scores 6, 5, and 4. Which failure mode should the team prioritize first?
AMislabeled syringe, because its severity score is high
BOmitted allergy check, because its severity is highest
CWrong-dose entry, because its priority number is highest
DDelayed administration, because its occurrence is high
Correct: Wrong-dose entry, because its priority number is highest.
Rationale

FMEA prioritizes by risk priority number — severity × occurrence × detectability. Wrong-dose entry scores 5×6×6 = 180, the highest of the four (mislabeled 96, omitted allergy 90, delayed 120), so it is addressed first even though it does not carry the top severity rating.

Why the other options are wrong

Mislabeled syringe (RPN 96) has high severity but low occurrence. Omitted allergy check has the single highest severity yet the lowest RPN at 90 — the classic trap of ranking on severity alone. Delayed administration (RPN 120) is second, not first.

3. A team pilots a new discharge-teaching checklist with six patients and finds that readmission-related callbacks dropped, but nurses skipped the medication-review portion because it sat at the bottom of a long form. What is the team's best next step in the improvement cycle?
AScale the checklist to the full department without retesting
BAbandon the checklist and return to the prior process
CRefer the low completion rate to leadership for a decision
DAdjust the form layout and run another small test cycle
Correct: Adjust the form layout and run another small test cycle.
Rationale

The pilot showed a promising signal alongside a specific, fixable design flaw — exactly what PDSA is built for: adapt the change and test the revised version in another small cycle before committing further. Modifying the form and re-piloting preserves the gains while correcting the omission.

Why the other options are wrong

Scaling department-wide bakes the known defect into wider practice before it is fixed. Abandoning the checklist discards a change that already reduced callbacks over a correctable flaw. Escalating to leadership offloads a routine iteration the team is equipped to make itself.

4. A fall-reduction team built this Pareto chart of fall locations. Where should the team focus its first PDSA cycle?
80% 40 Bathroom 33 Bedside 14 Hallway 9 Chair 4 Shower 100 0
AShower and chair
BBathroom and bedside
CMainly the hallway
DSpread evenly
Correct: Bathroom and bedside.
Rationale

Bathroom (40) and bedside (33) are the two tallest bars and account for the bulk of the cumulative percentage, making them the highest-yield focus for the first improvement cycle.

Why the other options are wrong

Shower and chair are the trivial many. Hallway alone misses the two largest sources. Spreading evenly ignores the vital few.

5. A quality manager must compare central-line infection performance between a 30-bed unit and a 12-bed unit that places far fewer central lines, and wants the comparison to be fair despite the difference in line usage. Which measure should the manager report?
AThe total count of infections recorded on each unit
BThe infections per 1,000 central-line days on each unit
CThe percentage of unit beds occupied by line patients
DThe number of central lines newly placed each month
Correct: The infections per 1,000 central-line days on each unit.
Rationale

A raw count is not comparable across units with different exposure. Expressing infections per 1,000 central-line days normalizes for how much and how long lines are actually in use, producing a rate that lets the two units be compared on equal footing.

Why the other options are wrong

A total count rewards the smaller unit simply for having fewer patients. Percentage of beds occupied describes census, not infection risk. Lines placed per month captures device volume but omits infection events and dwell time.
