I'm a new nurse. I had a really busy day at work. While I was in the middle of doing so many things I think I used the wrong needle to give a flu vaccine. Ugh why did I do it!? I realized afterward that I used the 23 guage 1 inch needle I believe. I gave the flu vaccine with 23 gauge 1 inch needle to a husband and wife. /we use this needle on kids usually. The husband barely had any meat on his bones while the wife easily had atleast 1-2 inches of fat on her arms. im freaking out. what will happen to them if the needle is too short?? is this oK? or will there be serious issues??
