Final answer:
The statement is false; a daughter can act as a designated agent to pick up a prescription for her mother, which does not relate to the concept of children's competence to provide consent.
Step-by-step explanation:
The statement is false. While Mrs. Patel can indeed have her daughter pick up the prescription for her, the daughter does so in the role of a designated agent. A designated agent is someone who is authorized to act on behalf of another person, in this case, picking up a prescription. However, the information provided which states that 'children are not competent to provide consent for themselves' refers to the idea that minors generally cannot give legal consent and is not directly related to the scenario of a daughter acting as an agent for her mother.
