What are the functions of the endocrine system?
-Maintian and regulate cital functions
-growth and development
-metabolism of energy
-muscle and adipose tissue distribution
-fluid and electrolyte balance
What do hormones do?
regulate and integrate body functions
What is the difference between endocrine and exocrine glands?
endocrine secrete into blood
exocrine secrete into another organ
What is Negative feedback?
sensors detect changes in hormone levels and respond to regulate the level. Example would be if gulcose is to high insulin is released.
What are some common causes of hormonal disorders?

-side effects from treatments(steroids)
What are some abnormal pyshical findings for hormonal disorders?

Also palpation of the thyroid gland
What is hypothyroid?

High levels of thyroid hormone
also known as

-monitor for med interactions(no calcium and vitamins at the same time of med)
Who does hypothyroidism most commonly affect?
occurs most frequently in older woman
What is Creatnism?

-dry, itchy skin
-Weight loss/ increased appetite
-bowel and menstrual changes
What are post op concerns for a thyroidectomy?
-hypocalcium(check calcium levels post op)
* reasoning- parathyroid can be damaged or removed resulting in low calcium
What are some medical treatments for HYPERthyroidism?
-PTU ana ntithyroid agent that inhibits the release of thyroid hormone. It is used until Euthyroid is reached, and the pt is weaned off of it.
-131 I or thyroid storm is a radioactive iodine the destroys overreactive thyroid cells. given in 1 dose by a radiologist.closely monitor cardiac for dysrthmea, and fever, and neuro impairment
What is the function of the parathyroid?
What does parathormone do?
regulates calcium and phosphorus balance.
Insulin glargine can be mixed with regular insulin,
True or False
False. Glargine insulin is not compatable with normal insulin such a s Humulin R or Novolin
Cool and Clammy give them ????
(Hypoglyciemia) they need sugar.
Hot and Dry .....
Sugar is TOO High ! Pt needs insulin.
Low parathormone causes what?
Increase in serum phosphate, and decrease in serum calcium
What is hypoparathyroidism?
Low parathormone production,
-can be caused from surgery, trauma or the atrophy of the gland.
Increase in phosphate and decrease in calcium can cause what?
TETANY? (test question)
Low levels of serum calcium which causes muscle tremors, twitching, uncoordinated movement, numbness and tingling in extremities and face, can lead to bronchospasms, and death.
What is a considered a normal level of serum calcium?

What is the biggest risk factor for type 1 diabetes?
Genetice predisposition combined with immunologic enviromental factors.
Type 1 pathophysiology?
-inability of beta cells to produce insulin.
-glucose cannot be stored
-kidnesy cannot reabsorb the glucose so it is in urine
Type 2 Pathophysiology?
-insulin resistance (decreased tissue sensitivity to insulin)
-cellular membrane resistance
