A nurse is assessing a client who is admitted for elective surgery and has a history of AddisonÔÇÖs disease. Which of the following findings should the nurse expect?

The correct answer is C: Hyperpigmentation. Addison's disease is characterized by adrenal insufficiency, leading to decreased production of cortisol and aldosterone. This results in increased production of ACTH, which can cause hyperpigmentation, especially in sun-exposed areas. Purple striations (A) are seen in Cushing's syndrome, not Addison's. Hirsutism (B) is excessive hair growth, commonly seen in conditions like polycystic ovary syndrome, not Addison's. Intention tremors (D) are associated with cerebellar dysfunction, not typically seen in Addison's.
