Erm...I don't know whether to laugh or get irritated :P

We recently had our first experience of head nursing for two weeks. I really don't know whether to laugh or to get irritated. It seemed like our juniors were so dependent on us that they would literally consult every action. One approached me (I hope she doesn't read this...I believe she's not a member of the forum) and asked me "Help, I can't read the IV level of my patient." So I turned to her and asked her why. So why wasn't she able to read it? "I can't see the numbers, they're on the back" See? I don't know whether to laugh...or is posting this be evil for her had she known I did?
