Review the 4-day trend after a medication error and answer the three questions.

Quick answer
Partially effective — family disclosure and second-victim support occurred, but RCA was delayed until Day 6.

Why this is correct
The response addressed the patient and the nurse promptly, but the system-level analysis (RCA) was not initiated until Day 6, leaving a gap in early system learning.

Clinical picture
In a just culture, immediate priorities are patient care, family disclosure, and staff support. The RCA should be convened as soon as feasible, typically within 24-72 hours, to capture details and begin system fixes.

Memory hook
RCA timing is a key indicator of organizational safety maturity. Delays beyond 72 hours are considered a weakness in the response.

NCLEX decision rule
Evaluate the response phase by phase: patient/family, staff, system. A delay in any phase reduces overall effectiveness.

Why the alternatives are wrong
Ineffective — disclosure was withheld: Incorrect; disclosure occurred on Day 2. Fully effective — all phases timely: Incorrect; RCA was delayed. Ineffective — night RN punished without RCA: Incorrect; RCA was formed, though late, and the nurse received support.
