What are the two primary mechanisms for hormonal imbalances (high or
low)? Right Ans - 1) inappropriate amounts of hormone delivered to the
target cell
2) inappropriate responses by the target cell

What are 4 reasons for inappropriate hormone amounts? Right Ans - 1)
endocrine gland disorders causing inappropriate synthesis
2) failure of the feedback systems
3) dysfunctional or ectopically produced hormone
4) defects in delivery of the hormone in the blood stream

what does ADH stand for? What does it do? Right Ans - - antidiuretic
hormone
- holds onto water

What condition is associated with TBI leading to increased water excretion?
Right Ans - neurogenic diabetes insipidus

What happens during diabetes insipidus and how does the body attempt to
correct the problem? Right Ans - Decreased excretion of ADH
increased water excretion = polyuria
hypovolemia
polydipsia - increased thirst, attempt to make up for volume loss

What endocrine gland is responsible for diabetes insipidus? Right Ans -
posterior pituitary gland

What endocrine gland is responsible for SIADH? Right Ans - posterior
pituitary gland

What does SIADH stand for? Right Ans - Syndrome of inappropriate
antidiuretic hormone

What is SIADH characterized by? Right Ans - high levels of ADH -
dilutional hyponatremia and hypervolemia

,What different diseases is SIADH associated with? Right Ans - - ectopic
excretion by tumor cells
- pulmonary disorders
- CNS disorders

What is the thyroid gland associated with? Right Ans - metabolism, growth,
development

What kind of feedback loop is used by the thyroid? Right Ans - negative
feedback loop

Describe the loop of thyroid feedback? Right Ans - T3 T4 decrease below
normal, hypothalamus releases TRH, pituitary stimulated to produce TSH,
thyroid gland produce T3 T4
hormones rise, hypothalamus turns off TRH, stopping pituitary release of TSH

what lab value is associated with hypOthyroidism? Right Ans - high TSH

(body trying to increase T3/T4, but. body not responding, thus more TSH,
continuing loop)

What lab value is associated with hypERthyroidism? Right Ans - low TSH

(body sees to much T3/T4, stops TSH production)

What is hypOthyroidism characterized by? Right Ans - decreased T3/T4 =
decreased metabolism.
Sx: constipation, bradycardia, dyspnea, lethargy

What condition is associated with hypERthyroidism? Right Ans - Graves
Disease

What does Graves Disease results from? Right Ans - Type 2
hypersensitivity reaction in which there is an antibody response against the
TSH receptor

What is the most common form of DM1? Right Ans - immune-mediated
diabetes

, What is Type 1 DM? Right Ans - pancreatic dysfunction secondary to Type
1 Beta-cell destruction
ABSOLUTE INSULIN DEFICIENCY

Are DM1 patients usually obese? Right Ans - No, they are not usually obese

What is Type 2 DM? Right Ans - a chronic metabolic disease characterized
by defects in pancreatic insulin secretion and insulin resistance on target
tissues, resultant hyperglycemia

What is insulin resistance? Right Ans - suboptimal response of insulin-
sensitive tissues (esp liver, muscle, and adipose) to insulin

What is GLP-1? Right Ans - - glucagon-like peptide 1
- incretin that aims to reduce BG, improvs beta-cell responsiveness in pre-
diabetes and DMT2

What is one of the most important contributors to both insulin resistance and
diabetes? Right Ans - obesity

What are the 4 primary complications of diabetes? Right Ans - 1) DKA
2) HHNKS
3) Microvascular disease
4) Macrovascular disease

Why is screening for DM important? Right Ans - complications are
signficant

What is the best test to check long term glucose control? Right Ans -
HgbA1c - glycosylated hemoglobin

Over what period of time does HgbA1c check glucose control? Right Ans -
3-4 months

What is DKA Right Ans - diabetic ketoacidosis

What are three primary causes for DKA? Right Ans - 1) infection
2) new dx
3) non-adherence to treatment plan
