Hi, I'm doing a nursing care plan for a client who experienced complications/side effects with using a PCA pump (mostly felt drowsy, later nausea and vomiting). I don't know which nursing diagnosis would be best for this client. I thought there was one for ineffective pain management, but there is none. What should be my diagnosis? I tried looking for other nursing diagnoses but none seem appropriate to what I want to talk about. Or should I just use the nursing diagnosis of Acute pain since her pain is originally from having multiple bone fractures.
