I agree with previous posters and with what you did. Definitely chart. I'm not a nurse yet, but this is something I do know about. I'm a medical transcriptionist who has a client who's an OB/GYN. I don't do his "regular" transcription but his medicolegal work. He acts as an expert witness in many malpractice cases. I can't tell you the number of times a nurse and/or the practice doctor has had their butts saved because telephone calls were properly documented. Lack of such documentation results in a "he said, she said" situation and can get extremely messy. Sometimes the plaintiff seems to have forgotten all about a telephone call, but its existence ends up changing the whole outlook of the case and often results in my client pretty much saying that there's no case to answer. I often hear about telephone calls to pharmacies too, and they can be relevant in some cases.
Bottom line is, document, document, document. I have a sneaking suspicion you're heard that mantra before. :wink2:
Of course, it could work against you, but only if you weren't practicing safe in the first place.
Keep on doing what you're doing and stop doubting yourself. It's not the MA's license that's on the line.
