Question 1 of 5
A 29-year-old woman with systemic lupus erythematosus has been treated with corticosteroid therapy for several years because of recurrent lupus nephritis. She undergoes an emergency appendectomy for acute appendicitis. On postoperative day 2, she becomes somnolent and develops severe nausea and vomiting. She then becomes hypotensive. Blood cultures are negative, and laboratory studies now show Na+ of 128 mmol/L, K+ of 4.9 mmol/L, Cl- of 89 mmol/L, CO2 of 19 mmol/L, glucose of 52 mg/dL, and creatinine of 1.3 mg/dL. Which of the following morphologic findings in the adrenal gland cortex is most likely to be present in this patient?
Correct Answer: B
Rationale: This woman has findings of acute adrenocortical insufficiency (acute addisonian crisis). Long-term corticosteroid therapy shuts off corticotropin stimulation to the adrenal glands, leading to adrenal atrophy. When this history is not elicited, and the patient is not continued on the corticosteroid therapy, a crisis ensues, in this case made worse by the stress of surgery.
