Final answer:
The inner aspect of the forearm is an ideal location for an intradermal injection if it meets specific criteria.
Step-by-step explanation:
An intradermal injection can be given in the inner aspect of the forearm when certain criteria are met. Firstly, it should not be the patient's dominant arm to avoid restricting function. Secondly, the area should be free of any skin lesions that might impede evaluation. Finally, the forearm should be easily moved by the patient to facilitate absorption of the medication.
