The nurse observed that a client with depression sat at a table with two other clients during lunch. What is the best feedback the nurse could give the client?

Choice A reason: Lithium is primarily used for bipolar disorder to stabilize mood swings. It is not effective for transient psychotic symptoms in borderline personality disorder, which are better managed with antipsychotics.

Choice B reason: Benzodiazepines are used for anxiety and agitation but are not appropriate for treating psychotic symptoms. They can also lead to dependence and are not considered first-line for borderline personality disorder psychotic features.

Choice C reason: Anticonvulsant mood stabilizers can help with mood instability and impulsivity but are not the primary treatment for psychotic symptoms. They may be adjunctive but not the most effective option.

Choice D reason: Antipsychotics are the treatment of choice for transient psychotic symptoms in borderline personality disorder. These medications target hallucinations, delusions, and severe thought disturbances, making them the most appropriate intervention.

Choice A reason: Relaxed inhibitions, increased appetite, and distorted perceptions are more characteristic of cannabis intoxication rather than stimulants. Cannabis use often leads to increased appetite ("the munchies") and perceptual distortions, but stimulants typically suppress appetite and increase alertness.

Choice B reason: Depersonalization, dilated pupils, and visual hallucinations are more consistent with hallucinogen intoxication such as LSD or PCP. While stimulants can cause dilated pupils, the presence of depersonalization and hallucinations points more toward hallucinogens rather than stimulants.

Choice C reason: Slurred speech, unsteady gait, and impaired concentration are typical of alcohol intoxication or sedative-hypnotic use. These substances depress the central nervous system, leading to impaired motor coordination and speech, which are not features of stimulant intoxication.

Choice D reason: Hyperactivity, talkativeness, and euphoria are hallmark signs of stimulant intoxication. Stimulants such as cocaine, amphetamines, and methamphetamine increase dopamine and norepinephrine activity, leading to heightened energy, excessive talking, and feelings of intense pleasure or euphoria. These behaviors directly reflect the pharmacologic effects of stimulants on the central nervous system.
