I've worked as the RN for an ALF. I always called in a home health IV agency to start the IVs, due to the liability, and the fact that there was enough work to do already. I instructed the caregivers (usually CNAs) in how to do personal care around an IV site - beyond that, they weren't allowed to touch them. The IV therapies were usually short term, for hydration, or for IV antibiotics managed by the agency nurses. If the resident is really sick and unstable, they should be in a hospital, or have a hospice agency involved if they're needing terminal care. The administrator will always object to hospitalization, even if it's best for your resident, because the resident doesn't pay rent while they're admitted. The admin will want to do IV therapy, because in most ALF companies, they can then charge more for the RN in-house to monitor it, because the level of care has gone up. For the admins, it's ALL about income. The families should be told these things, but sometimes aren't. Your resident will get safer care in the hospital - maybe fewer personal touches from kind caregivers like yourself, but at least safe care.
Even if your state allowed CNAs to start IVs, you're not being paid enough for that kind of liability. We're all better off sticking to what we do often, and do well.
And beware of administrators in assisted living, or LTC, that used to be CNAs or even LPNs. These folks think that since they've had some management training, they know everything that RNs know. They are "wannabe" nurses who quite likely were not good CNAs - otherwise they'd still be involved in nursing. They are being paid good money, as long as they bring in income for the facility. Admins. who were never nurses tend to know their limits. Steer clear of this woman until she does something to embarrass or anger the owners. You could also report her anonymously for her statement about IVs, to the state board of nursing, and they would make a random drop-in visit to check on things.
Good luck to you! Keep up the good work.
