A nurse is interviewing a client who reports ongoing feelings of depression after the death of his sibling 9 months ago. Which of the following actions should the nurse take?

The correct answer is B: Explain to the client that the duration of grief is highly variable and can last for years. This is the most appropriate action because it acknowledges the client's feelings of depression and grief as valid and normal following the death of a loved one. By explaining the variability in the duration of grief, the nurse provides reassurance and validation to the client's experience. This approach helps in normalizing the client's emotions and promotes a sense of understanding and acceptance.
Choice A is incorrect because recommending solitary activities may worsen the client's depression by isolating them. Choice C is incorrect as encouraging avoidance of discussing the death can hinder the client's grieving process. Choice D is incorrect as cautioning against feeling angry can invalidate the client's emotions.
