Final answer:
Nursing assistants in an acute mental health setting can be delegated the task of checking for sharp objects, but tasks like assessing mental status, administering medication, and discussing treatment plans are not part of their responsibilities.
Step-by-step explanation:
The question pertains to the roles and responsibilities that may be delegated to a nursing assistant in an acute mental health setting. Among the tasks listed, checking for sharp objects is within the scope of a nursing assistant's duties. Assessing mental status upon admission, administering medication, and discussing the treatment plan are responsibilities that typically require higher levels of training and licensure and would not be delegated to a nursing assistant. The nursing assistant works under the direct supervision of a registered nurse or another licensed healthcare professional, focusing on direct patient care tasks that do not require clinical judgment or complex medical knowledge.
