Yes, grandparents can give medical consent if a parent or legal guardian has authorized them to make healthcare decisions for the child. The grandparent must present a signed medical consent form before the child can receive medical care. In an emergency, the document is essential as healthcare professionals will not perform medical procedures until they see they have permission. If you grant a grandparent authorization, you should ensure they store the document in an accessible place. This way, your child can then receive medical care without delay, and you can avoid unnecessary stress.
