Free Practice Questions for NAHQ CPHQ Exam

The Nominal Group Technique (NGT) is a structured method for group brainstorming that encourages contributions from everyone12. It is designed to facilitate quick agreement on the relative importance of issues, problems, or solutions2. The process involves participants identifying and contributing ideas toward a topic or question specified by the facilitator1. Participants then discuss and individually prioritize the ideas1. This method ensures that the opinions of all group members are taken into account and prevents the discussion and process from being dominated by an individual participant1. Therefore, it encourages equal participation from all team members.

The NAHQ CPHQ exam blueprint highlights the importance of leadership engagement and strategic alignment when launching quality improvement initiatives. Senior management requires a clear understanding of what is being proposed and what resources are required to support it.

A proposed plan outlines goals, scope, and expected outcomes, while resources needed clarify staffing, financial, and infrastructure requirements. Together, these elements support informed decision-making and executive sponsorship.

Other options lack either strategic context or complete resource justification, making Option D the most appropriate and CPHQ-aligned response.

 A run chart is a graph that displays observed data in a time sequence1. It is often used to visualize trends or patterns over time1. In the context of healthcare quality, a run chart would be the most suitable tool to display nosocomial infection rates over time1. This is because it allows for the tracking of changes in the data over time, which can help in identifying any trends or shifts in the process1. This can be particularly useful in monitoring infection rates, as it can help in identifying periodsof increase or decrease, which can then be investigated further1.

Under the Patient Safety domain, a just culture emphasizes balancing individual accountability with system accountability.

This approach focuses on learning from errors, improving system processes, and ensuring staff are treated fairly — distinguishing between human error, at-risk behavior, and reckless conduct.

Repeating assessments and pursuing reliability are important but not the defining characteristic of just culture.

Performance improvement (PI) in healthcare refers to the systematic process of identifying, analyzing, and enhancing the various aspects of healthcare delivery to improve patient outcomes, safety, and satisfaction1.

PI requires a collaborative and data-driven approach that involves multiple stakeholders, such as clinicians, managers, patients, and quality professionals2.

According to the National Association for Healthcare Quality (NAHQ), one of the core competencies for healthcare quality professionals is to facilitate teams and lead change initiatives that align with the organization’s strategic goals and priorities3.

NAHQ also recommends using a variety of performance improvement methodologies, such as Lean, Six Sigma, robust process improvement, and A3 problem-solving, to address complex and cross-functional issues in healthcare.

Therefore, the option that most likely benefits the PI goals of the organization is C. cross-functional processes evaluated by multidisciplinary teams with the support of management. This option reflects the best practices of PI in healthcare, as it fosters a culture of quality, engages diverse perspectives, and leverages data and evidence to drive improvement23 .

The other options are less likely to benefit the PI goals of the organization, as they are either too narrow, too top-down, or too siloed. These options may limit the scope, effectiveness, and sustainability of PI efforts, as they do not involve the relevant stakeholders, address the root causes, or align with the strategic vision of the organization23 . References:

NAHQ guidance emphasizes that initial improvement goals should be realistic, achievable, and benchmark-based. Setting the national benchmark (1.00) as the initial goal aligns performance with external standards and supports incremental improvement.

While zero harm is the ultimate aim, setting an immediate goal of 0.00 may be unrealistic and discouraging. Goals below benchmark are more appropriate after sustained improvement. Therefore, Option B is the correct initial goal.

The most significant limitation of the sampling methodology in which a hospital collects patient satisfaction data by mailing surveys to discharged patients is the potential non-representativeness of the respondents. This can lead to biased results because:

Response Bias: The patients who choose to respond to the survey may have different experiences or opinions compared to those who do not respond. For example, individuals with very positive or very negative experiences may be more motivated to complete and return the survey, while those with neutral experiences may not bother to respond. This creates a response bias.

Nonresponse Bias: If a significant portion of the patient population does not respond to the survey, the data collected may not accurately reflect the overall patient satisfaction. This can result in an overestimation or underestimation of patient satisfaction levels, leading to incorrect conclusions and potentially flawed quality improvement strategies.

Sampling Bias: Since the survey is voluntary, there is no guarantee that the sample of respondents is representative of the entire discharged patient population. Factors such as age, literacy, socioeconomic status, and health condition might influence who responds, further skewing the results.

Impact on Data Validity: The lack of representativeness can compromise the validity of the findings. Decision-makers relying on these survey results may implement changes based on incomplete or biased information, which might not address the needs or concerns of the broader patient population.

The Ishikawa diagram, also known as a fishbone diagram or cause-and-effect diagram, is the best tool to determine the root cause of variations in a process. This diagram helps teams visually map out all potential causes of a problem, categorizing them into major factors such as methods, machinery, materials, and people. By exploring these potential causes systematically, teams can identify the root causes of variations and focus their improvement efforts accordingly.

Histogram (A): A histogram is used to display the distribution of data points but does not help in identifying root causes.

Shewhart chart (C): Also known as a control chart, it monitors process stability over time but is not specifically for root cause analysis.

Scatter plot (D): A scatter plot shows relationships between two variables but does not identify root causes of variations.

Sustaining knowledge from performance improvement (PI) training requires embedding learned concepts into routine practice to ensure long-term application and cultural integration.

Option A (Integrating key improvement teachings into daily work): This is the correct answer. The NAHQ CPHQ study guide states, “Integrating performance improvement principles into daily workflows ensures sustained knowledge application and reinforces a culture of quality” (Domain 3). For example, using PDSA cycles in routine problem-solving embeds training concepts.

Option B (Rewarding demonstrations of performance improvement): Rewards can motivate but do not ensure knowledge retention as effectively as daily integration.

Option C (Using simulations to illustrate complex concepts): Simulations aid initial learning but are less effective for sustaining knowledge compared to ongoing practice.

Option D (Requiring repeat training and reassessments): Repeat training may reinforce knowledge but is resource-intensive and less effective than practical application in daily work.

CPHQ Objective Reference: Domain 3: Organizational Leadership, Objective 3.3, “Develop and sustain training programs,” emphasizes embedding training into practice. The NAHQ study guide notes, “Sustained learning occurs when improvement concepts are applied in daily operations, reinforcing training” (Domain 3).

Rationale: Integrating PI teachings into daily work ensures continuous application, making it the most effective for sustaining knowledge, as per CPHQ’s training principles.

In the Performance and Process Improvement domain, the chart provided is a bar chart (histogram) showing the timing of pre-employment health assessments.

The largest percentage of employees falls under category A ("Left before health assessment completed") and B ("Still incomplete"), followed by C ("Later than four weeks").

This pattern shows that a majority of assessments were not completed before employment began, indicating non-compliance with the intended process requirement that assessments be finalized prior to duty assumption.

This variation represents a process breakdown requiring root cause analysis and corrective action to ensure timely completion.

In the Organizational Leadership domain, the first step in implementing system-wide change is to assess the current state — in this case, evaluating the existing quality assurance model to understand structure, processes, and limitations.

This assessment establishes a baseline and guides strategy development for transition to a multidisciplinary model. Leadership commitment and communication follow once the baseline and needs are clearly identified.

The NAHQ CPHQ exam blueprint emphasizes that foundational education in quality improvement must begin with a shared understanding of quality definitions, principles, and methodologies. These elements create a common language and framework that enables consistent application of improvement concepts across the organization.

Option C is correct because quality definitions (e.g., structure, process, outcome measures) and principles (e.g., systems thinking, continuous improvement, data-driven decision-making) are essential for building competency and alignment. Without this foundation, staff may misinterpret improvement goals or apply tools inconsistently.

Option A may be useful in applied learning but is not foundational. Option B is related to human resources processes, not QI education. Option D suggests individualized rather than system-focused improvement, which conflicts with CPHQ principles.

The CPHQ framework prioritizes standardized education to support sustainable improvement, making Option C the correct answer.

Before implementing a new infection prevention protocol in a clinic, the first step for a qualityprofessional should be to solicit support from key stakeholders. This step is crucial for several reasons:

Building Consensus and Buy-In: Gaining the support of key stakeholders, such as clinic leadership, department heads, and influential staff members, is critical for the successful implementation of the new protocol. Without their buy-in, the protocol may face resistance, which can hinder its effectiveness.

Resource Allocation: Key stakeholders often control the resources—both financial and human—that are necessary for the implementation of new protocols. Their support ensures that the necessary resources are allocated and that the protocol is prioritized within the organization.

Ensuring Alignment with Organizational Goals: Engaging stakeholders ensures that the new protocol aligns with the clinic's broader goals and priorities. This alignment increases the likelihood that the protocol will be integrated smoothly into existing practices and will be supported by ongoing quality improvement efforts.

Facilitating Communication and Education: Once stakeholder support is secured, they can help champion the protocol, assist with communication efforts, and advocate for necessary staff education and training, all of which are critical for successful implementation.

The preferred culture in promoting patient safety is one that promotes learning from mistakes and fosters collaboration. This is because a culture that promotes learning from mistakes encourages a non-punitive environment where individuals feel safe to report errors and near misses. This openness allows for the identification of systemic issues that can be addressed to prevent future errors1.

On the other hand, fostering collaboration is crucial in patient safety as it encourages open communication and teamwork among healthcare professionals. Collaboration ensures that all team members can contribute their expertise to patient care, which can lead to improved patient outcomes23.
