|
What is the function of the endocrine system?
|
To control or regulate metabolic processes.
|
|
|
What is hypopituitarism?
|
Diminished or deficient secretion of pituitary hormones
|
|
|
What is the most common cause of hypopitu.?
|
Tumors
|
|
|
What is constitutional growth delay?
|
It refers to individuals with delayed linear growth.
|
|
|
How do they treat constitutional growth delay?
|
They dont. Usually GH is not indicated because they will eventually "catch up" in growth.
|
|
|
How do they diagnose pituitary growth problems?
|
Stimulating growth hormone secretions.
(Usually done 20-30mins after exercise or 40-90 mins after sleep because that is when GH is being secreted the most) |
|
|
How do they treat GH deficiency?
|
By replacing GH through therapy.
|
|
|
When is GH usually given and why?
|
GH is usually given before bedtime to go with the body's normal secretion pattern.
|
|
|
Pituitary Hyperfuncion: Define
|
Excess GH before closure of the epiphyseal shafts results in proportional overgrowth of the long bones.
Proportional enlargement of head circumference also occurs and could delay closure of the fontanels. |
|
|
Define Acromegaly.
|
Over-secretion of GH occurs after epiphyseal a closure. Growth occurs in transverse direction which cause this condition.
|
|
|
What are possible complications from acromegaly?
|
Hyperglycemia and DM (Diabetes Mellitus)
|
|
|
How do they diagnose Pituitary hyper-secretion?
|
Diagnosis is based on a history of excessive growth during childhood and evidence of increased levels of GH.
|
|
|
Nursing Care Management of Pituitary Hyper-secretion
|
Identify children with excessive growth rates.
-Refer for medical evaluation -Observes for signs of a tumor |
|
|
Precocious Puberty: Define
|
Early sexual development before age 9 for boys and age 8 for girls
|
|
|
Central Precocious Puberty: Define
|
early puberty that is caused by GnRH (gonadtropin releasing hormone)
|
|
|
Peripheral Precocious Puberty: Define
|
Hormones other than GnRH causes early puberty development.
|
|
|
Precocious Puberty-Therapeutic Management
|
Administration of luteinizing hormone-releasing hormone. It causes breast development to regress and growth rates to return to normal.
|
|
|
When is precocious treatment discontinued?
|
At a chronologically appropriate time, allowing pubertal changes to resume.
|
|
|
What causes Diabetes Insipidus?
|
under-secretion of ADH (Antidiuretic Hormone); producing a state of uncontrolled diuresis.
|
|
|
What are the cardinal signs of DI (Diabetes Insipidus)?
|
Polyuria and polydipsia
|
|
|
How do they diagnose Diabetes Insipidus?
|
Oral fluids restricted to see if urine formation will still occur; weight loss between 3-5% indicates dehydration.
|
|
|
Why is aqueous vasopressin given in DI?
|
To alleviate polyuria and polydipsia.
|
|
|
How is DI treated?
|
hormone replacement of ADH.
|
|
|
Diabetes Insipidus: Nursing Management
|
-monitor I/O
-educate parents on lifelong treatment |
|
|
SIADH: Define.
|
Oversecretion of the ADH from the posterior pituitary
|
|
|
What does excess ADH cause?
|
It causes most of the filtered water to be reabsorbed from the kidneys back into central circulation. Serum osmolality is low and urine osmo. will be high.
|
|
|
What is the immediate management for SIADH?
|
Fluid restriction.
|
|
|
SIADH: Nursing Care Management
|
-accurate I/O's
-daily weight -observe for fluid overload -seizure precautions implemented |
|
|
What two hormones does the thyroid gland secrete?
|
TH and calcitonin.
|
|
|
What is the main action of TH?
|
To regulate the basal metabolic rate which controls the process of growth.
|
|
|
What is the main action of calcitonin?
|
It helps maintain blood calcium levels by decreasing calcium concentration.
|
|
|
What is the main action of PTH (parathyroid hormone)?
|
Increases concentration of Calcium in the blood.
|
