A nurse is caring for an adolescent who is scheduled for insertion of an intrauterine device. Which of the following actions should the nurse take?

A. Calling the guardian to obtain verbal consent may not be necessary if the adolescent is legally able to consent to reproductive health services, depending on state laws. The nurse should understand the legal requirements regarding consent for minors. B. Encouraging the adolescent to wait until after the procedure to ask questions undermines informed consent and can increase anxiety. The adolescent should be encouraged to ask questions before the procedure to ensure understanding and comfort. C. Witnessing the adolescent's signature on the consent form is an appropriate nursing action, confirming that the adolescent has voluntarily agreed to the procedure after receiving adequate information. D. Rescheduling the procedure until guardian consent is obtained is not always required if the adolescent has legal authority to consent. The nurse should verify legal guidelines rather than automatically delay care.
