Nope nope nope. I only read the first paragraph and skimmed the rest. I'd check your laws for staffing ratios at the very least.
1) We had a dry spell this summer. We follow a strict staffing ratio, and one night our census was so low that it left one RN (a new grad, nonetheless) and one CRN (who is a bada** RN but had only been in the CRN role for two weeks at this point). They had a code and it was pretty devastating. There wasn't even resources to even begin the code appropriately. Thankfully, the patient was fine, but it really opened admin's eyes to the potential dangers. Apparently they were turning a patient and couldn't hear the vfib alarm on another patient at the nurse's station. When they left the patient's room and heard the alarm, they scrambled to start a code.
2) Our critical care unit consists of a 14-bed intensive care unit and an 8-bed progressive care unit. The PCU hss a minimum of 2 RNs and usually one tech. These patients are still VERY ill, in that they'll be downgraded to PCU a day or two after extubation and stay in PCU for a week or so. We are allowed to have feeding tubes and drips. Sometimes our patients are a "wait to intubate" ED admit, that they keep PCU level overnight until the pulmonologist can intubate in the morning. We RNs each have a 4-patient team (My team last week was two Afib with RVRs, one post-heart stent who kept having long runs of vtach with reperfussion, and one with respiratory failure satting a sustained 82% on continuous BiPap). It's TOUGH. Sometimes the other RN is JUST as busy, and often our aide will "float" to ICU to clean a stool or turn a patient. If my patient goes downhill, and the other RN is doing a med pass down the hall and our aide is in ICU, I'm pretty screwed. It's happened before and it will happen again. Sometimes I'll call my CRN on my cell and holler for them. This unit is L-shaped too, so there's many places you really can't yell for help. The two RNs and one aide make me nervous, I can't imagine one RN!!
