NURS 3303 EXAM 5 - FINAL Questions and
Correct Answers/ Latest Update / Already
Graded
Tropic Hormones

Ans: - stimulating hormones
- Hypothalamus
- Pituitary


Hypothalamic-Pituitary-Hormonal Axis

Ans: - the hypothalamus secretes a releasing factor that
stimulates the pituitary gland
- pituitary is stimulated - releases a "tropic" hormone that
targets a specific endocrine organ
- target endocrine organ secretes a hormone that acts on the
body and causes a physiologic effect


Pituitary Gland (Master Gland)

Ans: - regulates all the other endocrine glands
- two lobes: anterior & posterior
- responds to hypothalamus signal by releasing a tropic
hormone
- signals an endocrine gland to secrete a specific hormone

- senses rise in that hormone in the blood, ceases tropic
hormone signal = negative feedback loop


Anterior Pituitary Gland

Ans: - growth hormone
- adrenocorticotropic hormone (ACTH)


Posterior Pituitary Gland (neurohypophysis)

Ans: - TSH
- FHS
- LH


Endocrine Gland Receptors: Down Regulation

Ans: - prolonged stimulation of an endocrine gland's receptor
cells by pituitary = decreased number of receptors = decreased
sensitivity


Endocrine Gland Receptors: UP Regulation

Ans: - inadequate stimulation = increased number of receptor
cells = increased sensitivity

Endocrine Disorders

Ans: - endocrine dysfunction occurs when the hypothalamus -
pituitary-hormone axis is disrupted
3 types of Endocrine disease:
- Hormone DEFICIENCY
- Hormone EXCESS
- Hormone RESISTANCE


Deficiencies Hormones

Ans: Occur because of glandular destruction due to:
- Autoimmune disease (overstimulation/overproduction)
- Inflammation
- Infarction
- Tumor infiltration


EXCESS Hormone

Ans: occur because of tumors, autoimmune disorders, genetic
mutations


Primary Disorder

Ans: dysfunction caused by the endocrine gland itself

Secondary Disorder

Ans: dysfunction caused by abnormal pituitary activity


Tertiary Disorder

Ans: dysfunction caused by a hypothalamic origin


Posterior Pituitary Gland Disorder: Low ADH

Ans: - Vasopressin
- AKA Diabetes Insipidus (DI)
Caused By:
- Head trauma
- Tumor
- Pituitary surgery
- Toxins


Signs and Symptoms of Low ADH

Ans: - increased urine output (polyuria)
- decreased H2O in blood causes increase in Na+
- Dehydration
- increased thirst (polydipsia)
