A nurse in a mental health clinic is caring for a client who has bipolar disorder and a prescription for an antipsychotic medication. The provider and nursing staff suspect the client is not adhering to his medication therapy. Which of the following interventions should the staff use to encourage the client's adherence? (Select all that apply.)

The correct interventions to encourage the client's adherence are using sustained-release forms, providing once-daily dosing, and performing mouth checks following medication administration. Sustained-release forms help maintain consistent blood levels, reducing the need for frequent dosing, thus improving adherence. Once-daily dosing simplifies the medication regimen, making it easier for the client to remember and follow. Performing mouth checks helps ensure the client is actually taking the medication. Rotating staff may disrupt rapport and consistency, affecting trust. Engaging in conversation may not directly impact adherence. Thus, choices A and B are incorrect.
