Parents agree to certain interventions, such as IV line placement, when they seek medical care. Any previous consent would apply to this situation—the parents would need to actively protest further treatment at this point. Furthermore, routine procedures that are noninvasive or have low risk of harm and considered routine and do not require formal consent. The friends are trying to be protective of the child, so it is best to diffuse the situation. Asking them to watch what you are doing and explaining the process can decrease their anxieties.
