Question:
The appropriate needle gauge for intradermal injection is:

Option A):
20G
Option B):
26G
Option C):
25G
Option D):
22G

Correct Answer is Option B):
26G

Explanation:
Because an intradermal injection does not penetrate deeply into the skin, a small-bore 25G needle is recommended. This type of injection is used primarily to administer antigens to evaluate reactions for allergy or sensitivity studies. A 20G needle is usually used for I.M. injections of oilbased medications; a 22G needle for I.M. injections; and a 25G needle, for I.M. injections; and a 25G needle, for subcutaneous insulin injections.
