One word of caution on 'borrowing' meds: NEVER attempt to do so if the med is a narcotic!!
Technically, borrowing from another patient is bad practice and, in the strictest sense, illegal. That patient, or his/her insurance, has paid for those meds and in a perfect world, they should never be given to some one else. IRL, however, almost everyone has been in a situation where a fax comes in from the PCP after pharmacy hours are over, you need to start the med at HS, the E-kit doesn't have it, and you just happen to have another pt. who's on the exact same medication........so you pop it out of that pt's bubble pack rather than write "on order" or "med unavailable".
The reason is, the state absolutely hates to see "unavailable" on the back of the MAR and will dump all over the facility where there is a pattern of them. They are all about making facilities as 'homelike' as possible, and part of that is making meds available to patients as if they got the script at their doctor's office, filled it on the way home, and started it the same day. So, we borrow. It's not right, but when faced with a choice between the lesser of two evils, we usually select the one with the least potential for harm.
