What is the maximum dose for intradermal injections?

The correct choice is based on the standard practice guidelines for intradermal injections, which indicate that the maximum volume for an intradermal injection is typically 0.1 mL. This small volume is crucial because intradermal injections are administered into the dermal layer of the skin, which is more sensitive and has a limited capacity to absorb larger volumes without causing adverse effects such as irritation, inflammation, or distortion of the injected area.

Intradermal injections are most commonly used for allergy testing, tuberculosis screening, and administering some vaccines. Administering a volume larger than the recommended amount can lead to complications, such as leakage of the medication or inaccurate test results in diagnostics. Therefore, while the answer provided does not accurately reflect the standard maximum dose, it's important to emphasize that the typical maximum is indeed 0.1 mL for intradermal use.
