| Question | Answer |
|---|---|
| Posterior pituitary | secretes ADH Raises bp Increases water absorption |
| Anterior pituitary | GH, TSH, Lh, FSH, |
| Thyroid | T3 T4 Increases metabolic rate |
| The pituitary gland is connected to the hypothalamus via the | Infandibulum |
| The hypothalamus produces 2 hormones | ADH and Oxytocin |
| ADH and Oxytocin is stored in the | posterior pituitary |
| Pineal gland | located in the brain and releases melatonin |
| Pituitary gland is divided into two sections the anterior and posterior the anterior.... | is larger and made of glandular tissue |
| Posterior pituitary is smaller and | made of neural tissue |
| Posterior STORES 2 hormones made by the hypothalamus | ADH and Oxytocin |
| ACTH | Adrenal Corticotropic hormone produced by the anterior pituitary targets the adrenal glands |
| TSH | released by anterior pituitary |
| Thyroid | produces T3 and T4 and calcatonin regulates metabolism |
| calcitonin | prohibits the release of calcium from the bones this lowers the serum CA+ level Stops urinary secretion of calcium (calci-NO-nin)=lower Ca+ |
| 4 nodules embedded in tissue in the thyroid | parathyroid |
| parathyroid | releases parathormone |
| parathormone | releases calcium into the blood and increases serum calcium level |
| thymus | located in the chest and is responsible for T cell maturation releases thymosin and thymopoietin |
| Adrenal cortex | Sweet salty sex androgens, aldosterone, and glucocortioids (barking sex) |
| Adrenal medulla | catacholamines Epi and norEpi (inside I'm scared) |
| pancreas | only endocrine and exocrine gland insulin and glucagon and somastatin |
| Beta cells produce | insulin lowers blood sugar |
| alpha cells | produce glucagon increases blood sugar |
| somastatin | "cruise control" keeps blood sugar regulated |
| pheochromocytoma | tumor of the adrenal gland usually benign |
| s/sx of hyperthyroidism | fine thin stringy hair, heat intolerance, weight loss, increased appetite, bug eyes hyperglycemia, increased levels of T3 and T4 decreased serum TSH |
| medication for hyperthyroidism | PTU (propylthiouracil) given at the same time q. day WITH FOOD |
| complication of hyperthyroidism | thyroid storm: S/SX: fever, dehydration, tachycardia, n/v, diarrhea, HF, confusion, and death |
| hypothyroidism | intolerance to cold, facial edema, fatigue, slow speech, anorexia, weight gain,brittle nails and hair, constipation, dry skin, menstrual disturbances decreased T3 and T4 Increase in TSH |
| addisons disease | affects the adrenal cortex bronze skin, bearded lady, GI dist., hypoglycemia, weight loss, postural hypo tension, reduced vascular volume |
| labs for addisons disease | low Na+ and high K+ |
| thyroid post-op care | neck support when turning and TCDB keep a suction kit at bedside |
| medication for hypothyroidism | levothyroxine: before meals in the morning |
| pheochromocytoma nursing care | don't palpate the abdomen |
| DI Diabetes Insipidus causes | head injury, pituitary tumor, or crainiotomy |
| DI s/sx | up to 20L/day urination decreased: urine specific gravity (less than 1.010), osmolarity, BP Increased: thirst Tachycardia |
| DI nursing care | monitor I/O, replace fluids frequent neuro checks |
| Pathophysiology for DI | decreased ADH secreations from the anterior pituitary |
| Cushings syndrome S/Sx | moon face, personality changes, increase r/o infection, gynecomastia, truncal obesity, buffalo hump, hyperglycemia, bruises and petechia |
| causes of cushings syndrome | hypersecretion of cortisol from the adrenal glands |
| ~bonus~ tetraiodothyrodine | hormone produced by the thyroid that regulates metabolsim |
