Re: I feel so stupid. What should I have done?
Sounds like you did the right thing, UTI's in elderly can be so tricky! I am a new grad, so I don't have much nursing experience to share with you, but my first degree is in psychology and this is where I can add my 2 pennies!
You can actually use one of those textbook phrases on the son; "It must be so difficult for you to see your mother in so much pain."
Unless this is his everyday attitude, the son isn't a jerk nor does he really think it is 'all your fault'. He's scared and angry that his mother is deteriorating and he has zero control over it. He feels powerless and is projecting that fear and anger onto the closest person, you.
Try the above phrase and see if he is able to open up. We meet people in the most vulnerable states and often take the brunt of outbursts. You did a great job at critical thinking, don't let the incident take that from you.
