An adult is being evaluated for a possible pituitary tumor. What test(s) does the nurse expect may be ordered for this client to confirm the diagnosis? Select all that apply.
Correct Answer: C,F
Rationale: To confirm a pituitary tumor diagnosis, imaging and functional tests are essential. An MRI (C) is the gold standard for visualizing pituitary tumors due to its detailed imaging of soft tissues. A visual field test (F) assesses any potential impact on vision, as pituitary tumors can compress the optic chiasm, leading to visual field deficits.
The other options are less relevant: 24-hour urine (A) may be useful for assessing hormone levels but is not definitive for tumor diagnosis. PT and PTT (B) evaluate coagulation, which is unrelated. Nerve conduction studies (D) assess peripheral nerve function and do not pertain to pituitary evaluation. A skull x-ray (E) is outdated for this purpose, as MRI provides superior information.
