Maybe she’s a newer nurse and just read the stuff wrong? Not that there is an excuse when you’re in the medical field to be messing up like that…but at least she can learn from her mistakes. If more mistakes keep happening tho I’d consider switching
Sometimes it could just be input wrong. I'd have them retake it.
I would call them and have them adjust it/bring you back in to redo it! Especially when it comes to his growth, you want the correct measurements recorded.
