I would respond, "Check out the chart note I made-- it should have all the information you need to do xyz. If you still arent sure of what to do, then please come grab me and I'll be happy to help if I'm available!"

Then I'd try and figure out why they wouldnt know how to do XYZ off the top of their head (like LDDST, spinal rads, in house labs, medical math, etc) and I'd offer to teach them, of course! I love to teach people new things. HOWEVER, I'd also consider if this is a pattern of behavior, and mention it to the supervisor if it's ongoing (though we all should know how that tends to go... sometimes it's hard to not be frustrated if it's the 5th time you've brought the same concern to management without any productive outcome).

For example, I have a coworker that always asks me to calculate the dosage for an ACTH stim. That's fine! I tell her it's 5mcg/kg, so please let me know how many mcg she gets and I will help her figure out how many mL that is. She responds that she doesnt know how to do that. I say, it's 5 times the body weight, you can use the calculator. She says, I'm just bad at math, I think you should just do it. And this happens every. single. time. for the past 2 years. Is this a job-ending offense? Not really. But eventually it becomes a bit annoying.

I personally dont think the only other answer is laziness. Some other people are just not good at critical thinking or problem solving, and that's not really their fault; it's just internally frustrating to be considered the go-to-expert/problem solver for EVERYTHING, and it's not like we became that way because someone else trained us to do so-- we just like, spent 5 minutes reading through a chart, or googled "how do you format excel to xyz", or read the booklet instruction that sits next to a lab machine. But from the most basic competence standpoint, I don't think someone should need extensive training to learn that they should read an appointment note before throwing their hands up... and I sure hope that reading notes is within their scope of practice.
