What should you expect to see after administering an intradermal injection?

After administering an intradermal injection, you should expect to see a wheal. This reaction is characterized by a raised, swollen area that appears at the injection site due to the small volume of fluid that is introduced into the dermal layer of the skin. The wheal forms as the body responds to the injected substance, typically as part of a diagnostic test for allergies or other conditions, reflecting an immediate hypersensitivity reaction.

Redness and swelling may occur at the injection site, but they are not the primary expectation for an intradermal injection. Instead, the wheal is the most definitive indicator that the injection has been successful. Blisters and bruising are not typical outcomes of an intradermal injection; blisters can indicate a more significant reaction or irritation, while bruising might occur due to other factors such as needle trauma or incorrect injection technique.
