What type of syringe is typically used for intradermal injections?

Intradermal injections are performed to administer small volumes of medication just below the outer layer of the skin. The accurate choice involves a 1-mL tuberculin syringe with a 25- to 27-gauge needle, which is ideal for this type of injection for several reasons.

The 1-mL tuberculin syringe allows for precise measurement of small doses, typically ranging from 0.01 to 0.1 mL, which is sufficient for intradermal administration. The use of a finer gauge needle, like the 25- to 27-gauge, minimizes the potential for discomfort and helps achieve the correct angle and depth required for the injection, ensuring that the medication remains within the dermal layer. Additionally, these needles are specifically designed for intradermal procedures, offering better control and accuracy when injecting.

In contrast, larger syringes and needles, such as those mentioned in the other options, are more suited for subcutaneous or intramuscular injections where larger volumes and deeper penetration are required. For example, the 3-mL and 5-mL syringes indicated would be excessive and not provide the precision needed for an intradermal injection, while the 10-mL
