A nurse on a mental health unit is planning a group therapy session about assertiveness training. For which of the following clients should the nurse recommend the training?

Choice A reason: Delirium is an acute cognitive disturbance requiring medical stabilization. Assertiveness training is not appropriate during this phase. Choice B reason: Auditory hallucinations may impair reality testing and concentration, making participation in assertiveness training ineffective or distressing. Choice C reason: Mania involves elevated mood, impulsivity, and distractibility, which can interfere with the structured learning required in assertiveness training. Choice D reason: Clients with somatic symptom disorder often struggle with expressing emotional needs and boundaries. Assertiveness training can help improve communication and reduce reliance on physical symptoms to express distress.
