I have found that my techs or PCA's where I work have been a blessing from above. I make sure that if I need frequent vitals I remind them every so often, oh by the way did you remember to get the vitals for Mrs. so and so. I believe that if you have a mutual respect that makes a big difference. I have no hesitation if I'm asked to helpout with a boost, etc. And I will usually make it clear that if you need any help, let me know. Also, I will explain certain things, if there's a remrk made about what the big deal is for daily wts, etc. I will take a few seconds to explain the reasoning behind the chore. When someone understands why it is being done, they are more likely to comply with it. Also remember that they are busy also with their work, and maybe consider doing rounds together once a shift. You can go in the room, have an extra hand to turn the pt while you check their sacrum and listen to their lungs. While your in their you change the brief, or whatever, while you're assessing pt, Pca can get vitals, change trash, etc. And then you can move on to the ext pt room. Then when you sit down to chart, all of your pt are repositioned and comfy, and it will be easier for the PCA to answer call lights and keep up with other things.
