Quick answerTest hourly rounding on one hallway and measure what happens. PDSA favors a small, observable first test rather than an immediate organization-wide rollout.
Why this is correctA limited trial reduces risk and makes cause-and-effect easier to observe. The team can compare fall events, call-light use, and workflow problems, study the result, and revise the next cycle before expanding the intervention.
Easy analogy or mental pictureA PDSA test is like trying a recipe in one small pan before cooking it for an entire banquet. The small batch reveals what needs adjustment, but a successful local test still requires thoughtful evaluation before broad adoption.
Memory hookPlan the change, do it small, study the data, then act on what was learned.NCLEX decision ruleWhen an NCLEX item asks for the first PDSA action, choose a defined small-scale test with a measurable outcome. Do not choose immediate full implementation, policy replacement without data, or passive delay.
Why the other choices are wrongUnit-wide rollout skips the learning phase. Replacing policy after one meeting does not test performance, and waiting for annual data delays a low-risk improvement that can be evaluated now.
