A patient with suspected adrenal insufficiency has been ordered an adrenocorticotropic hormone (ACTH) stimulation test. Administration of ACTH caused a marked increase in cortisol levels. How should the nurse interpret this finding?
A) The patient's pituitary function is compromised.
B) The patient's adrenal insufficiency is not treatable.
C) The patient has insufficient hypothalamic function.
D) The patient would benefit from surgery.
Ans: A
Feedback:
An adrenal response to the administration of a stimulating hormone suggests inadequate production of the stimulating hormone. In this case, ACTH is produced by the pituitary and, consequently, pituitary hypofunction is suggested. Hypothalamic function is not relevant to the physiology of this problem. Treatment exists, although surgery is not likely indicated.
