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
