A young adult female visits the mental health clinic complaining of diarrhea, headache, and muscle aches. She is afebrile, denies chills, and all laboratory findings are within normal limits. During the physical assessment, the client tells the nurse that her sister thinks she is neurotic and calls her a hypochondriac. Which response is best for the nurse to provide?

A) Dismissing the sister's comments may invalidate the client's feelings and concerns. B) While acknowledging the impact of the sister's comments is important, addressing the client's immediate concerns is more therapeutic. C) Suggesting that the client might be a hypochondriac could be perceived as accusatory and may escalate the situation. D) This response acknowledges the client's distress caused by the sister's comments while also exploring other potential stressors in the client's life.
