I like to alleviate anxiety when possible, but I always explain that it's a scope of practice issue; the doctor will have to interpret the results so I really shouldn't be giving them if I can't interpret them specifically for that patient.
So. Middle-aged lady whose troponin is over 40, but has stabilized a bit and can breathe, is on cardiac drips, has atypical or no chest pain, and normally denies what symptoms she does have, is anxious about her lab results. Hm. Add that it's 3 am and she finally is clearheaded enough to be worried, she slept all day and no doc is coming through in the next 4 hours to explain things to her. I want her to rest; she wants to know something so she can rest. She says, "the doc mentioned my number on my enzymes was high, did I have a heart attack?" I explain scope of practice and then a bit about my background. "From my experience, what the doc meant was that your heart is definitely having a problem, but he's going to have to explain to you how severe it is." That gets me around the interpretation business, the lady is not completely stupid, just needs a little info and will gladly wait on the interpretation. We then move on to plan of care issues like, I want to know symptoms, and she will rest and relax, if she needs help with that, I've got what she needs.
It's not always that scripted but it's really painless to explain things to people if you mention scope of practice. It certainly keeps you from putting your foot in your mouth and having to deal with it later.
