Anyone been a PCA for "security checks"??

I had an interview today at my #1 choice hospital for a PCA position. I get there, and they inform me that most of my job will be security checks / watches for suicidal people, 72 hour holds, combative patients, etc. Basically, I will have to sit one on one with someone and watch them. I will have a different assignment every day, sometimes a few in a day, in different areas of the hospital. Also, I will be scheduled occasionally to be on the floor as a float in different departments.

Negatives: It sounds like I will be BORED OUT OF MY MIND just sitting there, and also be mentally exhausted depending on the patient. I won't get to sharpen my skills as much (I'm a fairly new CNA and never worked in a hospital). I won't have a "home unit".

Positives: It would be a plus to get to know different areas of the hospital, and meeting more people = making more connections. I would possibly get to observe a lot. Also, it is a way to get my foot in the door and the nurse manager who interviewed me said if something else opens up I can transfer to a different PCA position in 4 or 5 months.

If I get offered the job, I'm thinking I should take it. Just wondering if anyone has thoughts or experience with this, and can give me any more insight into this position!!! Thank you.
