List at least three diagnostic test for Acromegaly. | In addition to H and P, 1. evaluation of plasma IGF-1 levels, 2. evaluation of IGF binding protein–3 (IGFBP-3) levels, and 3. GH response to an oral glucose challenge., 4. CT scanning with contrast 5. and MRI |
After surgery in which a transsphenoidal approach has been used, list at least two nursing actions. | 1. HOB up 30 degrees, 2.Monitoring neurologic status, including pupillary response, 3.clear nasal drainage should be sent to the laboratory to be tested for glucose. |
A possible postoperative complication is transient diabetes insipidus (DI). Why? | DI may occur because of the loss of antidiuretic hormone (ADH), which is stored in the posterior lobe of the pituitary gland, or cerebral edema related to manipulation of the pituitary during surgery. To assess for DI, urine output and serum and urine os |
