Final answer:
The correct intervention for a client with paranoid schizophrenia is to remove medication from sealed packages at the client's bedside to build trust and ensure compliance.
Step-by-step explanation:
The appropriate intervention to include in the plan of care for a client who has paranoid schizophrenia is C.) Remove medication from sealed packages at the client's bedside. This is because patients with paranoid schizophrenia may have trust issues and are likely to be suspicious about their medication being tampered with. Removing medication from sealed packages in their presence can help to build trust and ensure compliance with the medication regimen. Rotating staff assignments could exacerbate the patient's paranoia, and using touch to calm the client during periods of anxiety might be perceived as threatening, given their condition. Moreover, unless the client has a specific impairment that prevents them from feeding themselves, assigning an assistive personnel to feed the client is not necessary and could be demeaning.
