Q

FUNCTIONS OF THE ENDOCRINE SYSTEM

Q

WHAT DOES THE ENDOCRINE SYSTEM DO

A
  1. GROWTH AND DEVELOPMENT
  2. SEX DIFFERENTIATION- REPRODUCTION
  3. METABOLISM-DIGESTION, USE AND STORAGE OF NUTRIENTS, REGULATION OF SOME ELECTROLYTES AND FLUIDS
  4. ADAPTATION TO AN EVERY CHANGING ENVIRONMENT- HOMEOSTASIS

Q

HOW DO HORMONES FUNCTION AS CHEMICAL MESSENGERS

A

MOVE THROUGH BLOOD TO DISTANT TARGET SITES OF ACTION.
CAN ACT LOCALLY AS PARACRINE OR AUTOCRINE MESSENGERS
MOST ARE PRESENT IN BODY FLUIDS AT ALL TIMES IN VARYING AMOUNTS

Q

CHARACTERISTICS OF HORMONES

A

SINGLE HORMONE CAN EXERT VARIOUS EFFECTS IN DIFFERENT ISSUES–> ESTRODIAL—FROM OVARY BUT DOES THINGS IN ALL KINDS OF TISSUES

SINGLE FUNCTION CAN BE REGULATED BY SEVERAL HORMONES-LIPOLISIS- BREAKDOWN OF FAT— TAKES SEVERAL HORMONES

A

tsh
acth
fsh
lh

120
Q

Explain the negative feedback mechanism involved in the regulation of thyroid hormones.

A

The Thyroid Feedback Mechanism. TH regulates TRH gene expression and production through a negative feedback mechanism; TRH expression is high when TH levels are low, and TRH expression is suppressed when TH levels are increased.

121
Q

What is the physiologic effect of insulin?

A

carb metabolism
increases rate of transport of glucose across the cell membrane in adipose tissue and muscle
increases rate of glycolysis
stimulates the rate of glycogen synthesis

122
Q

What is the physiologic effect of glucagon?

A

Glucagon is secreted into the portal vein and thus has its major physiologic action at the liver to break down glycogen.

123
Q

What happens to glucose when the liver and skeletal muscle tissue are saturated and can no longer store glycogen?

A

the “excess” glucose is “converted” to fat tissue through catabolism IN the fat cells, which essentially “grow” with the glucose consumed… and, by the way… this process actually burns off some of the glucose… about 10% of the amount stored is “burned” to store it.

124
Q

What clinical manifestations would be observed in a child with GH deficiency?

A

slow height growth each year after a child’s 3rd birthday. A child with GH deficiency may also have a younger-looking face and a chubby body build.

125
Q

What is the pathophysiology for Diabetes Insipidus (DI)?

A

when your body doesn’t make enough antidiuretic hormone (ADH) or your kidneys don’t use it properly. Your body needs ADH to retain appropriate amounts of water. Without ADH, your body loses water through urine. Diabetes mellitus is much more common than diabetes insipidus

126
Q

What is the pathophysiologic difference between type I and type II diabetes mellitus?

A

In diabetes type 1, the pancreas does not make insulin, because the body’s immune system attacks the islet cells in the pancreas that make insulin. In diabetes type 2, the pancreas makes less insulin than used to, and your body becomes resistant to insulin.

127
Q

What electrolyte imbalances should the nurse suspect in Addison’s disease?

A

hyponatremia, hyperkalemia, and hypoglycemia.

128
Q

What are the clinical manifestations of hypoglycemia?

A

Fast heartbeat.
Shaking.
Sweating.
Nervousness or anxiety.
Irritability or confusion.
Dizziness.
Hunger.

129
Q

What clinical manifestations may be seen in a client with Cushing’s Syndrome?

A

their face get round (“moon face”), they gain weight in unusual ways, bruise easily or feel weak, tired and sad.

Q

What electrolyte is involved in excitatory amino acid injury?

A

acid glutamate

131
Q

What is the difference between brain death and a persistent vegetative state?

A

A persistent vegetative state means the person has lost higher brain functions, but their undamaged brain stem still allows essential functions like heart rate and respiration to continue. A person in a vegetative state is alive and may recover to some degree, given time. Brain death means the person has died.

132
Q

Describe where production and flow of CSF occurs. What occurs when there is excess of CSF?

A

Hydrocephalus is a buildup of cerebrospinal fluid (CSF) in the spaces deep inside your brain (ventricles). As a result of the excess fluid, the ventricles widen and put pressure on the brain tissue. In hydrocephalus, the cycle that allows CSF fluid to flow freely is out of balance and fluid builds up in the ventricles.

133
Q

Order the meningeal layers of the brain starting from the outermost to innermost layer

A

dura mater
arachnoid
pia mater

134
Q

Interpret the Glasgow Coma Scale—what does it mean when the client’s GCS is increasing?Decreasing

A

Based on the level of consciousness, a score is assigned. A higher score indicates a greater level of consciousness. The GCS uses three sites for stimulation. This includes fingertip pressure, trapezius pinch and supraorbital notch.

135
Q

What cranial nerve is responsible for pupillary changes?

A

oculomotor nerve
cn iii

136
Q

what is the formula for cpp

A

cpp = map - icp

137
Q

what is normal icp

138
Q

what is normal cpp

A

60-80 mmhg

139
Q

What are the 3 major causes/classifications of increased ICP

A

brain, cerebrospinal fluid, and blood. Any increase in the volume of its contents will increase the pressure within the cranial vault. An increase in the volume of one component will result in a decrease in volume in one or two of the other components.

140
Q

Monroe-Kellie Hypothesis

A

What finally came to be known as the Monro-Kellie doctrine, or hypothesis, is that the sum of volumes of brain, CSF, and intracranial blood is constant. An increase in one should cause a decrease in one or both of the remaining two.

141
Q

What is the difference between a stroke and a TIA?

A

A TIA is a brief blockage of blood flow to part of the brain, spinal cord or the thin layer of tissue at the back of the eye known as the retina. This blockage may cause temporary stroke-like symptoms. But a TIA doesn’t damage brain cells or cause permanent disability. This is how it differs from a regular stroke.

142
Q

What vessel is commonly damaged in patients with epidural hematoma?

A

middle meningeal artery

143
Q

What acronym do we use to assess for s/s of stroke?

A

be fast
balance
eyes
face
arm
speech
time

144
Q

What is the target organ for FSH and LH?

A

anterior pituitary

145
Q

A __________ (primary, secondary,tertiary) disorder is associated with damage to the hypothalamus

146
Q

A tumor that causes damage to the thyroid gland is an example of a____________ (primary, secondary, tertiary) disorder.

147
Q

A tumor that destroys the posterior pituitary gland is an example of a____________(primary, secondary, tertiary) disorder?

148
Q

what stimulates the production of gh

149
Q

gh

A

somadotropin

150
Q

what inhibits the production of gh

A

somadastatin
ghih

151
Q

ghrh and ghih are released from

A

hypothalamus

152
Q

growth hormone
igf 1 deficiency

A
  • Idiopathic GH deficiency- Lacks hypothalamic
    GHRH
  • Pituitary tumors, agenesis of the pituitary- Cannot produce GH
  • Laron-type dwarfism- Hereditary defect in IGF production
153
Q

growth hormone
igf1
excess

A
  • Gigantism - childhood* Before puberty and fusion of epiphyseal plates
  • Acromegaly – adult* After fusion of epiphyseal plates
154
Q

gh excess in adults

A

Overgrowth of the small bones and cartilaginous parts of the skeleton
* Epiphyseal plates closed –don’t grow taller
* Enlargement of the heart and other organs of the body
* Metabolic disturbances resulting in altered fat metabolism and impaired glucose tolerance - can lead to diabetes
