The nurse demonstrates an appropriate use of outcome measurements on a mental health unit when:
Correct Answer: B
Rationale: The correct answer is B because reassigning a client's activity level based on his demonstration of disregard of appropriate social boundaries demonstrates using outcome measurements effectively in mental health care. This shows that the nurse is monitoring the client's behavior and adjusting the care plan accordingly to promote positive outcomes.
A is incorrect because requiring a caregiver to attend a discharge planning meeting does not directly relate to outcome measurements for the client's mental health progress.
C is incorrect because providing clean linen according to a schedule does not demonstrate the use of outcome measurements for mental health assessment and intervention.
D is incorrect because permitting the son to bring ethnic foods does not directly relate to monitoring and adjusting the client's care plan based on observed behaviors.
