Just as a note, the MA, not sure her name (sorry) she was very friendly, but she mentioned I needed shots Tetanus and Shingles. I asked if they could be done at the same time, and she googled it on her computer in front of me. This did not instill trust or knowledge in this MA. While she was getting the shots, I looked it up myself as she mentioned I could get them in each arm or the same arm. (CDC) advised giving one in each arm for about 6 different shots and these two were on the list. Which to my non-clinical knowledge meant for these two given together to do one in each arm. When she came back, she asked if I wanted them in each am or the same. I told her from what I could tell from CDC recommendations they should be in each arm, and she said ok. Non-pulsed, no apology. My recommendation, if she doesn't know something, is to say let me check and then check outside the pt viewing. Again, very friendly and personable and she said she had a lot of experience e in giving shots, which again, did not make me feel very comfortable if you use Google for your medical source of truth.
