1A nurse manager calculates HPPD for a 32-bed medical unit. Last week the unit recorded 192 nursing care hours per day across an average daily census of 24 patients. What is the HPPD?

A.6.0

B.8.0

C.0.125

D.768

Explanation: Hours Per Patient Day (HPPD) = total nursing hours worked divided by patient days. 192 nursing hours / 24 patient days = 8.0 HPPD. HPPD is the standard nurse manager metric used to compare actual staffing to a budgeted target and to benchmark against units with similar acuity.

21 FTE in U.S. healthcare staffing math is most accurately defined as which of the following?

A.1,950 paid hours per year

B.2,080 paid hours per year

C.2,080 productive hours per year (excludes PTO and orientation)

D.40 hours per pay period

Explanation: 1 Full-Time Equivalent (FTE) = 2,080 paid hours per year (40 hours per week x 52 weeks). This includes both productive hours (worked at the bedside) and non-productive hours (PTO, education, orientation). Productive FTE is a separate, smaller figure derived after subtracting non-productive time.

3A unit's productivity report shows: required hours = 360, actual hours worked = 400. What is the productivity index?

A.111%

B.90%

C.40%

D.1.11

Explanation: Productivity = (required hours / actual hours) x 100. 360 / 400 = 0.90 or 90%. A productivity index below 100% means the unit used more hours than the workload-based target, indicating an over-staffing variance the manager should investigate.

4A nurse manager reviews the monthly operating budget and finds salary expense was $48,000 over budget while patient days were 12% above plan. This is best categorized as which type of variance?

A.Unfavorable price variance

B.Favorable volume variance with associated volume-driven expense increase

C.Unfavorable efficiency variance

D.Capital budget variance

Explanation: Higher patient days (volume) typically drive higher salary expense because more nursing hours are needed. The volume itself is favorable (more revenue and care delivered); the expense increase that scales with volume is expected, not a sign of poor management. The right next step is to flex the budget for volume and re-examine the residual variance.

5Which staffing metric is most useful for comparing nursing labor cost across procedural areas like the OR or cath lab where length of stay is measured in hours, not days?

A.HPPD (Hours Per Patient Day)

B.HPUOS (Hours Per Unit Of Service)

C.Nurse-to-patient ratio

D.Productive FTE

Explanation: HPUOS (Hours Per Unit Of Service) flexes the unit of service to the area: OR minutes, cath lab cases, ED visits, infusion chairs, etc. HPPD assumes a midnight-census patient day and breaks down in procedural and short-stay areas. CNML candidates should be able to pick the right denominator for the care setting.

6On a med-surg unit, the nurse manager wants to convert HPPD to a nurse-to-patient ratio at the bedside on a 12-hour shift. The budgeted HPPD is 6.0. Approximately what nurse-to-patient ratio does this support, assuming RN-only direct care?

A.1:4

B.1:5

C.1:6

D.1:8

Explanation: With HPPD = 6.0 and RN-only direct care, each patient needs 6.0 nursing hours per 24-hour day, or 3.0 RN-hours per 12-hour shift. One RN provides 12 RN-hours per 12-hour shift. 12 RN-hours / 3.0 hours per patient = 4 patients per RN, so the supported ratio is 1:4. The general conversion is 24 / HPPD = patients per RN on 12-hour shifts (24 / 6.0 = 4).

7A staff RN announces resignation. Which sequence best represents an effective succession-planning response from the nurse manager?

A.Post the position externally and wait for HR to screen candidates

B.Identify internal high-potential staff already cross-trained, hold a stay conversation with the resigning nurse, and review the unit succession bench

C.Reassign the workload to remaining staff and defer hiring until budget review

D.Promote the most senior RN to fill the gap

Explanation: Effective succession planning is proactive: managers maintain a development bench, identify high-potential internal candidates ahead of vacancies, and use stay interviews to retain talent. Reactive external posting alone misses the opportunity to grow internal staff and shortens hiring lag.

8Which performance-improvement framework follows a four-step cycle: Plan, Do, Study, Act?

A.Lean

B.PDSA

C.Six Sigma DMAIC

D.A3 problem solving

Explanation: PDSA (Plan-Do-Study-Act), also called the Deming cycle, is the foundational rapid-cycle improvement model used throughout healthcare quality work. It is the engine of IHI Model for Improvement and is the most widely taught QI framework on the CNML.

9A unit-based council is reviewing a process problem and wants a single-page document that captures the current state, root cause, target state, and countermeasures. Which Lean tool fits?

A.Fishbone diagram

B.A3 report

C.Pareto chart

D.Run chart

Explanation: The A3 report is a Lean problem-solving document on a single A3-size page that walks the reader from problem statement and current state through root cause, target state, countermeasures, and follow-up. It is widely used in Lean-mature health systems.

10Which of these is a primary aim of the Pathway to Excellence framework, distinct from the Magnet Recognition Program?

A.Documenting nursing research output

B.Establishing a positive nursing practice environment with strong frontline staff voice

C.Achieving CMS Conditions of Participation

D.Replacing the unit-based council structure

Explanation: Pathway to Excellence focuses on a positive nursing practice environment built on six standards (shared decision-making, leadership, safety, quality, well-being, professional development). Magnet adds outcomes-driven research and exemplary professional practice expectations on top. Pathway is often the entry credential for organizations and is highly relevant for front-line nurse manager scope tested on CNML.

CNML: Suggested Study Strategy

1Master the financial math: HPPD, productivity (required/actual), 1 FTE = 2,080 hours, fixed vs variable cost, and variance analysis.

2Know the EBP models by name: Iowa (triggers, team, evidence, pilot), Johns Hopkins (PET), Stetler, ACE Star, Rosswurm and Larrabee.

3Memorize the difference between CNML (front-line manager) and CENP (executive) scope — the exam tests this directly.

4Be fluent in regulatory baselines: TJC NPSGs, CMS Conditions of Participation, HIPAA, OSHA Bloodborne Pathogens, EMTALA, FLSA, FMLA, NLRA Section 7.
