A 28-year-old woman with a history of unstable interpersonal relationships, self-harm, suicide attempts, mood lability, substance abuse, and extreme irritability presents to the psychiatric nurse practitioner for an evaluation. She states, “I just want to know what’s wrong with me. I feel like I spend 95% of my time either angry or on the floor crying in the fetal position.” The PMHNP suspects this client has borderline personality disorder. In this scenario, how would the discomfort the client experiences as a result of her behaviors best be described?

Choice A reason: Neural tube defects are commonly associated with folate deficiency and medications like valproic acid or carbamazepine, not lithium.

Choice B reason: Ebstein's anomaly is a congenital heart defect involving the tricuspid valve and is the most well-documented teratogenic risk associated with lithium exposure during the first trimester. It is rare but serious, making this the correct answer.

Choice C reason: Cleft palate is associated with various teratogens, including phenytoin and alcohol, but not typically with lithium.

Choice D reason: Floppy baby syndrome refers to hypotonia in infants and is most commonly linked to maternal benzodiazepine use, not lithium.

Choice A reason: Clear boundaries in a family system allow for healthy autonomy and appropriate involvement between members. A mother intervening in her adult daughter’s academic affairs suggests a lack of autonomy, which contradicts the concept of clear boundaries.

Choice B reason: Rigid boundaries are characterized by emotional distance and disengagement between family members. The mother’s overinvolvement in her daughter’s academic life does not reflect rigidity but rather excessive enmeshment.

Choice C reason: Diffuse boundaries are marked by overinvolvement, lack of autonomy, and blurred roles between family members. The mother’s action—intervening in her adult daughter’s academic affairs—demonstrates a lack of differentiation and autonomy, which is a hallmark of diffuse boundaries in structural family therapy.

Choice D reason: Individuation refers to the process of developing autonomy and a distinct identity. The mother’s behavior undermines individuation by not allowing her daughter to manage her own academic responsibilities.
