my hospital policy does Not recognize localized irritation as a "reaction". Depending upon the manufacturer you research, localized redness, swelling bruising, pain are common to administration sites.
What type of localized reaction are you watching for to classify it as such? Just curious.
We classify reactions as hives, not at insertion site, and all the anaphylactic signs.
Now hives at injection site that spreads to the trunk is different.
I'm just not getting the reason to cause two arms to hurt, and not understanding "watching for reactions".
If a patient gets two immunizations, no matter where the site and has a reaction it is impossible to know which one caused it with out giving an independent test dose of each.
This separate arm thing seems like nursing school
A reaction is an immune system mediated response that does not simply portray itself at the insertion point. I'm not sold.
