A nurse is caring for a client in an outpatient clinic. The medical record lists the client's name as "Brian" and sex as "male". The client states their name is "Brianna" and their gender is "female". Which of the following terms describes this client?

Providing culturally competent care requires understanding sexual orientation and gender identity terminology. Knowledge of the differences between biological sex assigned at birth and internal gender identity must be applied to correctly identify and support the patient's lived experience. Choice A rationale . Cisgender describes individuals whose gender identity aligns with the biological sex they were assigned at birth. Since this client identifies as female despite a male sex assignment, this term does not accurately describe their identity or experience. Choice B rationale . Bisexuality refers to a person's romantic or sexual attraction to more than one gender. This term describes sexual orientation rather than gender identity. It does not address the disconnect between the client's assigned sex and internal identity. Choice C rationale . Asexual describes individuals who experience little or no sexual attraction to others. Like bisexuality, this is a category of sexual orientation. It does not provide information regarding the client's gender identity or their transition from male to female. Choice D rationale . Transgender describes individuals whose gender identity differs from the sex assigned at birth. The client's self-identification as female while having a male designation in the medical record fits this definition precisely, requiring respectful and affirming nursing care.
