Agencies I've worked at rank the cases' priority 1, 2, and 3. The 2's and 3's would be ok without a nurse, having a reliable caregiver in the event of bad weather or other emergency. Priority 1 are the vents and other most intense cases. Some nurses are more flexible than others in availability, personal responsibilities, reliable transportation, etc. So hopefully they can pull the most available nurses off other cases to cover the most urgent ones. If someone is going into home health care, that person does need to decide how they are going to be reliable to their employer and their cases, at least most of the time. One way of doing this is to try and have or have access to an all wheel drive vehicle. I have a Subaru and I cannot say enough good things about it. Last week I drove in 9 inches of unplowed snow like it was nothing. Driving in snow is not as horrific as some would make it. A couple of inches isn't that bad. It can be done, just take it slow. Fortunately, there will be enough scared souls hiding at home for the roads to be less congested and easier to handle. Now, if it were straight ice on the roads, forget it. Trying to go anywhere on ice is foolhardy. That I will not do for any job.
