Pearson CPHQ New Attempt

Probability sampling ensures every individual in a population has a known, non-zero chance of being selected, providing a representative sample for statistical analysis.

Option A (Random sampling): This is the correct answer. Random sampling, where each patient has an equal chance of selection (e.g., using a random number generator), is a probability sampling method. NAHQ CPHQ study materials highlight random sampling as a rigorous approach for surveys to ensure unbiased results.

Option B (Convenience sampling): Convenience sampling (e.g., surveying available patients) is non-probability sampling, as it does not ensure representativeness and is prone to bias.

Option C (Focus group sampling): Focus group sampling is typically purposive (non-probability), selecting participants based on specific criteria, not random chance.

Option D (Quota sampling): Quota sampling is non-probability, as it involves selecting a fixed number of participants from predefined groups, not ensuring equal selection probability.

DMAIC (Define, Measure, Analyze, Improve, Control) is a Six Sigma methodology for process improvement, with each phase serving a specific purpose.

Option A (Measure): The Measure phase collects baseline data to understand current performance, not sustain improvements.

Option B (Analyze): The Analyze phase identifies root causes, not focused on sustaining new processes.

Option C (Improve): The Improve phase implements solutions, but does not ensure long-term sustainability.

Option D (Control): This is the correct answer. The NAHQ CPHQ study guide states, “The Control phase of DMAIC establishes monitoring systems and standardizes processes to sustain improvements over time” (Domain 4). Tools like control charts and standard operating procedures ensure performance is maintained.

CPHQ Objective Reference: Domain 4: Performance and Process Improvement, Objective 4.3, “Use structured improvement methodologies,” includes DMAIC’s Control phase for sustainability. The NAHQ study guide notes, “Control ensures improvements are sustained through ongoing monitoring and standardization” (Domain 4).

Rationale: The Control phase is designed to maintain process performance, aligning with CPHQ’s focus on sustainable improvement.

Engaging meeting participants requires active facilitation techniques to maintain focus, encourage participation, and achieve objectives.

Option A (Assigning a timekeeper among the meeting participants): A timekeeper helps manage time but does not directly engage participants in discussion or decision-making.

Option B (Sending out the meeting agenda one day prior to the meeting): An agenda prepares participants but does not ensure engagement during the meeting itself.

Option C (Using facilitative approaches during the meeting): This is the correct answer. The NAHQ CPHQ study guide states, “Facilitative approaches, such as encouraging input, managing group dynamics, and using interactive techniques, keep participants engaged and productive in meetings” (Domain 3). Examples include asking open-ended questions or using brainstorming.

Option D (Having the support items readily available before the meeting): Support items (e.g., handouts) aid preparation but do not actively engage participants during the meeting.

CPHQ Objective Reference: Domain 3: Organizational Leadership, Objective 3.2, “Facilitate effective meetings,” emphasizes facilitative approaches for engagement. The NAHQ study guide notes, “Facilitation techniques are critical for maintaining participant involvement and achieving meeting goals” (Domain 3).

Rationale: Facilitative approaches actively involve participants, ensuring engagement and productivity, as per CPHQ’s leadership principles.

The performance measure for infection control, such as the number of primary bloodstream infections per 1000 central line days, is an example of a rate. In epidemiology and public health, a rate is a measure of the frequency with which an event, such as a new case of illness, occurs in a population over a period of time. The denominator is the population at risk; the numerator is the number of occurrences of disease. Here, the number of primary bloodstream infections is the numerator, and the number of central line days is the denominator. Therefore, this measure is a rate.
