Chapter 10 Endocrine Function Flashcards
Deficient levels of GH, somatotropin, somatotropin releasing hormone cause _______ which results in short stature
Dwarfism
Refers to excessive fluid excretion in the kidneys caused by deficient ADH levels
Diabetes insipidus
Hypopituitarism can cause a decrease in GH which then leads to
Dwarfism
Refers to tall stature caused by excessive GH levels prior to puberty
Gigantism
Describes increased bone size caused by excessive GH levels in adulthood
Acromegaly
Refers to an abnormal enlargement of the thyroid gland
Usually evident as pronounced swelling of the neck
Goiter
Can occur in hyperthyroidism, hypothyroidism, and normal thyroid states
Goiter
Iron deficiency is the most common cause of __________ worldwide
Goiters
Treatment strategies for gigantism and acromegaly
Tumors will likely require surgery, radiation, and chemotherapy
Treatment strategies for dwarfism
Lifelong hormone replacement therapy
Increases the reabsorption of calcium from bones to blood; raises blood calcium
Increases reabsorption of calcium and excretion of phosphate by the kidneys
Increases reabsorption of by the small intestine
Blood calcium levels are critical, because calcium is essential for muscle contraction including the heart muscle.
Parathyroid hormone/ parathyroid gland function
ADH deflect disease
Profound diuresis occurs, person may excrete up to 25 liters of urine per day
Emergency replacement of fluids necessary or extreme dehydration will result
Hormone replacement therapy in most cases
Diabetes insipidus
Early detection of dehydration
Maintain adequate hydration
Accurately measuring I & O
Check urine specific gravity
Daily weights
Provide Po fluids in amount equal to urine output
If IV fluids, monitor hourly
Nursing interventions for diabetes insipidus
Treatment may include total or subtotal thyroidectomy; administration of anti thyroid drugs or radioactive iodine; or use if thyroid hormone to block release of TSH
Thyroid hormone replacement for life
Treatment strategies for a Goiter
Hyposecretion of thyroxine T4 in an adult
Decreased metabolic rate results in physical and mental lethargy
Most severe form of hypothyroidism
Characterized by swelling of hands, face including preorbital tissues, and feet
If untreated may lead to coma and death
Myxedema
Refers to a group of conditions characterized by hyperglycemia, resulting from defects in insulin production, insulin action, or both.
Diabetes mellitus
May be a result of excessive dietary carbohydrate intake as well as insufficient insulin. If the cells are starved for energy, the body may begin to break down fat producing toxic acids
Hyperglycemia
