Mary Jones, a nurse practitioner, is faced with a dilemma regarding Sandy Wilson's suspected pregnancy at the age of 15 years old. Despite her mother's wishes to keep the pregnancy confidential, Mary must take informed consent from Sandy and involve her mother in decision-making. This is because, as a minor, Sandy does not have the capacity to make decisions about her medical treatment. Mary should proceed with informing Sandy's mother and taking the best course of action for Sandy's protection and well-being, while also considering beneficence and respecting patient autonomy.
