Med decisions in LTC

I am applying to nursing school and joined this site to ease my way into the "community."

I have a grandmother in a LTC facility and was curious after my last visit.

How often do Drs make rounds in the LTC setting? and, how involved is the nursing staff with regard to medicating patients - not just passing them out but which meds should be used, etc. It seems that the staff would be more aware of which meds and dosages are working and if there are any side effects and/or complaints.

Just wanted to get some input...

Thanks!
