A nurse is caring for a school-age child who is taking valproic acid. The nurse should expect the provider to order which of the following diagnostic tests?

Borderline.

• A. Borderline personality disorder is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, and affect, as well as marked impulsivity and recurrent suicidal behavior. The client's history of seeking counseling for relationship problems and selfinflicted lacerations are consistent with this disorder. Therefore, this choice is correct.
• B. Antisocial personality disorder is characterized by a disregard for and violation of the rights of others, as well as a lack of remorse for one's actions. The client's behavior does not indicate this disorder. Therefore, this choice is incorrect.
• C. Paranoid personality disorder is characterized by a pervasive distrust and suspiciousness of others, as well as a tendency to interpret others' motives as malevolent. The client's behavior does not indicate this disorder. Therefore, this choice is incorrect.
• D. Histrionic personality disorder is characterized by excessive emotionality and attentionseeking behavior, as well as a tendency to dramatize situations and exaggerate emotions. The client's behavior does not indicate this disorder. Therefore, this choice is incorrect.

- A. Incorrect. The nurse should check the functioning of oxygen equipment daily, not weekly, to ensure safety and proper delivery of oxygen.

- B. Correct. The nurse should instruct the client to wear clothing made with cotton fabrics while oxygen is in use, as synthetic fabrics can generate static electricity and cause sparks that could ignite the oxygen.

- C. Incorrect. The nurse should instruct the client to avoid petroleum-based lubricants, such as Vaseline, as they are flammable and could cause burns if exposed to oxygen. The nurse should recommend water-soluble lubricants, such as K-Y jelly, instead.

- D. Incorrect. The nurse should instruct the client to store full oxygen tanks upright, not on their side, to prevent them from rolling and damaging the valve or regulator.
