NURS 6630 MIDTERM EXAM REVIEWA noncompliant patient states, “Why do you want me to put this poison in my body?” Identify the best response made by the psychiatric-mental health nurse practitioner (PMHNP). Selected Answer: C. “Most medications that work in the brain will result in restoring an imbalance of one or more neurotransmitters that your body already produces helping to alleviate your symptoms .” Ms. Hill is currently being treated for schizophrenia but has stopped taking her medications due to some side effects she claims she was experiencing.
