Answers to Exam Questions
- Answer D is correct. Prolactinoma tumors are tumors arising from hyperplasia of the pituitary gland that are prolactin hormone–based. Amenorrhea and anovulation are associated with prolactinomas because the pituitary gland assists with stimulation of the ovaries and ovulation, so answer A is incorrect. Because the pituitary is located in the center of the skull, adjacent to the brain, answers B and C are associated with increased intracranial pressure. Answer D is incorrect because weight gain can occur, not weight loss.
- Answer C is correct. Dostinex is used to shrink the prolactin-based tumor. Answers A and B are antineoplastic drugs. Answer D is an antiviral medication.

This hormone is associated with pregnancy. Answer D is incorrect because an elevated LDH is associated with muscle trauma. It is, however, elevated in a myocardial infarction.
