What action should take precedence if a client shows signs of an allergic reaction during a tattoo?

The best course of action when a client shows signs of an allergic reaction during a tattoo is to stop the procedure and seek medical assistance. Allergic reactions can manifest in various ways, such as swelling, redness, itching, or more severe symptoms like difficulty breathing or hives. Continuing the procedure could exacerbate the client's condition and lead to serious health complications.

Taking immediate action to stop the procedure helps ensure the safety and well-being of the client. Seeking medical assistance is vital because a trained healthcare professional can provide the necessary treatment, whether it's administering antihistamines or other interventions. Addressing the reaction promptly can prevent further complications and ensure the client receives appropriate care.

This approach prioritizes the client's health over completing the procedure, which is essential in any body art practice.
