A client has been diagnosed with a pituitary adenoma. Which of the following assessment findings supports that it is a nonfunctioning form?

20/40 vision using a Snellen chart
Rationale: Nonfunctioning pituitary adenomas produce symptoms caused by pressure of the tumor on surrounding structures, such as the optic nerve. Frequently, visual loss is the presenting symptom and it may be in the form of decreased acuity. Functioning pituitary adenomas produce endocrine symptoms, such as acromegaly or Cushing's syndrome. A protruding lower jaw, moon-shaped face, and insomnia are not associated with nonfunctioning pituitary adenomas.
