I might have mentioned this before, but it bears repeating: Use the mechanical lifts.
One of our larger residents has been suffering a decline in strength. It used to be that I could help them on and off the toilet without a problem and putting them to bed was easily doable by two people. Not any more. The other night their legs gave out before we could get them on the bed. Fortunately, I'm pretty strong, so I was able to pull them over and get them on the bed. Unfortunately, I pulled the tendon by my elbow. The resident is fine and I'm OK, but I'm going to have to baby my elbow until it's fully healed. Not an easy thing to do as a CNA. I'm hoping that I'll get more CMA work than I previously thought.
