How far from the bend of the elbow should an intradermal injection be administered?

• A. At least 2 inches from the bend of the elbow.
• B. Directly at the bend.
• C. 6 inches from the elbow.
• D. Next to the wrist.

Answer: (A)

For an intradermal injection, the site should be placed on the inner forearm, shallow under the skin, and kept away from the elbow joint. The best distance is at least 2 inches from the bend of the elbow, which places the injection in smooth forearm skin and in the proper depth for dermal administration. Being too close to the elbow bend can involve skin folds or movement that complicates the technique, while placing it near the wrist or much further away (like 6 inches) moves away from the standard forearm dermal area and isn’t practical for this type of injection. So, the recommended approach is to administer it at least 2 inches from the elbow bend.
