Congradulations on your new position "wish me luck". I work for the State of Nevada with an inpatient psychiatric hospital and have been with them for the past year or so. Prior to that, I worked for another organization affiliated with the state for about a year. They provided outpatient services.
I enjoy my job. The pay is rather low but I do like that they still retain a pension. Like any government job, they tend to be reactive rather than proactive about patient care. That can make change difficult. With young new minds, sometimes new ideas aren't welcomed. Regardless of whether we are psych nurses or not, we do still care for other co-morbidities. For example, many meds can technically prolong QT waves. We have to have the intuition to know when to further assess clients who may have history of heart problems as a result. Many antipsychotics can lead to metabolic syndrome as well. Knowing to look out for signs of significant weight gain or insulin resistance is therefore also important. Still other meds can lower the seizure thresholds. Many clients, especially those with history of seizure disorders thus have to be carefully watched. Teaching in med-surg like conditions will become part of your basic nursing interventions as a result. In other words, that idea of "they don't lose their bodies" may not be completely accurate.
Regardless, I hope you enjoy psych as much as I have. It's been a rewarding experience and I have gained so much from it. I hope you do too.
