Question

The preferred gauge of the needle for an SQ injection is___________.

a) 18-20
b) 22-25
c) 26-30
d) 14-16

Answer 1

The preferred needle gauge for an SQ injection is 22-25, which is optimal for reaching the subcutaneous tissue and minimizing discomfort.

Step-by-step explanation:

The preferred gauge of the needle for an SQ (subcutaneous) injection is 22-25. Subcutaneous injections are administered into the fatty tissue just below the skin. This type of injection is commonly used for vaccines, insulin, and heparin, and requires a needle that is long enough to reach the subcutaneous tissue but short enough to avoid deeper structures. A gauge of 22-25 is fine enough to cause minimal discomfort and large enough to properly administer the medication.
