Endocrinology II Endocrinology II 1 / 10 A patient with a pituitary tumor has a blood test revealing high levels of prolactin but low levels of other pituitary hormones. What is the most likely explanation? The tumor is affecting the hypothalamus, leading to decreased secretion of releasing hormones. The tumor is secreting prolactin directly, causing an overproduction. The patient has developed autoimmune destruction of the pituitary gland. The tumor is blocking the blood supply to the pituitary, causing overall hormone deficiency. 2 / 10 A 25-year-old woman experiences rapid heart rate, sweating, and anxiety before public speaking. Which hormone is primarily responsible for these symptoms? Insulin Estrogen Epinephrine (adrenaline) Thyroid-stimulating hormone (TSH) 3 / 10 A pregnant woman develops gestational diabetes. Which hormone produced by the placenta is primarily responsible for this condition? Insulin Human chorionic gonadotropin (hCG) Human placental lactogen (hPL) Placental growth hormone (hPG) 4 / 10 A patient experiences symptoms like anxiety, tremors, and weight gain after stopping long-term use of cortisol replacement therapy. This is an example of: Primary adrenal insufficiency Secondary adrenal insufficiency Cushing’s syndrome Addison’s disease 5 / 10 A newborn baby exhibits ambiguous genitalia, meaning the external sex organs are not clearly male or female. Which hormonal pathway disruption could be a potential cause? Estrogen deficiency Testosterone deficiency Pituitary gland dysfunction Congenital adrenal hyperplasia (CAH) 6 / 10 A 40-year-old woman experiences excessive thirst, frequent urination, and unexplained weight loss. What hormone imbalance is most likely the culprit? Growth hormone deficiency Hypothyroidism Hyperthyroidism Diabetes insipidus 7 / 10 Which hormone is responsible for stimulating the synthesis and secretion of cortisol? ACTH (Adrenocorticotropic hormone) GH (Growth hormone) TSH (Thyroid-stimulating hormone) FSH (Follicle-stimulating hormone) 8 / 10 Which condition is characterized by excessive secretion of growth hormone in adulthood? Cushing’s syndrome Acromegaly Addison’s disease Hyperthyroidism 9 / 10 Which hormone is primarily responsible for the regulation of water reabsorption in the kidneys? Vasopressin (ADH) Renin Atrial natriuretic peptide (ANP) Aldosterone 10 / 10 Which hormone is responsible for regulating appetite and satiety?
