When preparing to administer an intradermal injection to an adult, the nurse ensures that the dose amount does not exceed 0.1 mL. A 1 mL tuberculin syringe is used with a 25-gauge needle and is administered at which angle?

Choice A reason: A 12-degree angle is too shallow, increasing the risk of incorrect placement and ineffective administration of the intradermal injection. Choice B reason: The 15-degree angle ensures precise intradermal placement, forming a wheal that indicates proper administration into the dermis for optimal absorption. Choice C reason: A 30-degree angle places the medication too deep into subcutaneous tissue, compromising intended drug absorption. Choice D reason: A 45-degree angle results in subcutaneous rather than intradermal injection, altering the drug’s effectiveness and purpose.
