Correct answer: B · Support her and change how the look-alike bags are stored
AHRQ's PSNet describes a just culture as one that addresses the system issues behind unsafe acts while keeping individual accountability, with zero tolerance for reckless behavior. It separates human error, such as a slip, from at-risk behavior, such as a shortcut, and from reckless behavior, such as ignoring required safety steps, and it bases the response on the type of behavior, not on how severe the event was. This nurse followed every step and made a slip that the look-alike storage invited, so the fitting response is to support her and fix the storage. Discipline based on the harm the error could have caused judges by severity. Coaching about shortcuts fits at-risk behavior, which the stem rules out. Taking no action leaves the look-alike setup in place for the next nurse.
Look for this next time: In a just culture, the response depends on the behavior: a slip within a sound process calls for support and a system fix, not punishment.
