ENDOCRINESYSTEM AND MAJOR

DISORDERS

By: MISS SHENELL A. DELFIN, RN

FUNCTION:Endocrine system consist of a series of glands

“ductless” that function individually or conjointly to integrate and control innumerable metabolic activities in the body.

These glands automatically regulate various body processes by releasing chemical messengers called hormones.

OVERACTIVITY OR UNDERACTIVITY of any one of them affects the whole system.

FUNCTION:Control and coordination of the processes

which are wide spread in the body such as:Response to stress or injuryGrowth and developmentReproductionFluids and electrolytesAcid base-balanceEnergy metabolism

Endocrine Disorders

If you can remember what each hormone does in the body, it will be easier to remember what results from imbalances of that hormone. Most symptoms of hormone HYPERACTIVITY are the

opposite of symptoms of that hormones HYPOACTIVITY.

THYROID DISORDERS

Hypothyroidism underactive state of the thyroid gland hyposecretion of thyroid hormone most common in women, middle-age primary function is to control the level of cellular

metabolism by secreting thyroxin (T4) and triiodothyronine (T3)

DX: decreased T3, T4 Elevated TSH, cholesterol

HypothyroidismA state of low serum TH levels

or cellular resistance to TH

AutoimmuneDevelopment

alDietary

Iodine deficiencyOncologic

DrugsIatrogenicNon-

thyroidalEndocrine

Pathophysiology inadequate secretion of thyroid hormone

general slowing of all physical and mental process

metabolic rate oxidation of nutrients for energy heat production

Complications :• Cretinism – severe physical and mental

retardation resulting from severe deficiency of thyroid function in infancy or childhood (congenital hypothyroidism)

requires lifetime hormone replacement• Myxedema – occur from prolonged severe

disease accelerated devt. of coronary artery disease coma – rapid dev’t. of impaired consciousness and suppression of vital functions

MYXEDEMA COMA- a condition resulting from persistent low thyroid production.

Med. Mgt. – thyroid replacement therapy Levothyroxine (Synthyroid) , liothyronine Expected effects: diuresis, puffiness, improved reflexes and muscle tone, PR

Nsg. Interventions provide a warm environment, conducive to

rest avoid use of all sedatives assist client in choosing calorie, cholesterol

diet fluid and fiber to relieve constipation physical activity and sensory stimulation

gradually as condition improves monitor cardiovascular response to increased

hormone levels carefully provide info. about prescribed medications

(name, dosage, side effects) and importance of lifelong medical supervision

Hyperthyroidism

over-secretion of the thyroid gland also called thyrotoxicosis or graves disease, tissues are stimulated by excessive thyroid hormone a recurrent syndrome, may appear after emotional

stress or infection occurs mostly in women 20-50 yrs old

Causes : adenoma, goiter, viral inflammation, auto-immune glandular stimulation, grave’s disease - most common cause

Hyperthyroidism (cont.)

DX: > elevated T3, T4 valuesT4= 5-12mcg/dl , T3= 70-220 ng/dl , TSH= 0.2-5.4 mU/L• abnormal findings in the thyroid scan

Goiter – enlargement of the thyroid gland • due to stimulation of the thyroid gland by TSH

Simple goiter – enlarged thyroid gland• due to iodine deficiency, intake of goitrogenic

foods cabbage, turnips, soybeans• may be hereditary

Grave’s Disease disorder char. by one or more of the ff:

diffuse goiter

hyperthyroidism

infiltrative opthalmopathy exophthalmos seen in females under age 40 result from stimulation of the thyroid gland by thyroid-stimulating immunoglobulins (TSI) cause is unknown, may be hereditary, gender-

related, often occurs after severe emotional stress or infection

http://www.gifs.net/image/Hobbies_and_Entertainment/Excitement/Hot_head/10258

Complications :

cardiovascular disease (HPN, Angina, CHF) Exophthalmos – abnormal protrusion of the eyeballs

- caused by abnormal deposits of fat and fluid in the retroocular tissue

Corneal abrasion Thyroid storm or crisis life-threatening hypermetabolism and excessive adrenergic response (HR, RR, BP)

Thyroid Storm or Crisis

a medical emergency pts. develop severe manifestation of hyperthyroidism

temp., tachycardia, dysrhythmias worsening tremors, restlessness delirious or psychotic state or coma abdominal pain BP and RR

Precipitated by a major stressor: infection trauma or surgery (thyroidectomy) inadequate treatment

Do you take this woman as your wife…. In sickness and

in health…

TAKE ME! TAKE ME!!

Anxiety Flushed, smooth skin Heat intolerance Mood swings Diaphoresis Tachycardia Palpitations Dyspnea Delirium, coma Heart failure

Assessment Findings: Thyroid storm

Med. Mgt.• Medications

Propylthiouracil (PTU) – antithyroid drug - blocks thyroid hormone production- can cause agranulocytosis- monitor pt. CBC

Methimazole (Tapazole) – blocks TH prod. Iodine preparations – the size and vascularity of the thyroid gland; inhibit release of thyroid hormones 1.) Lugol’s solution

can be given with milk or fruit juice should be taken with a straw – may stain the teeth complications : brassy taste in the mouth, sore teeth and gums

2.) Saturated solution of potassium iodide (SSKI)

Med. Mgt.• Medications

Propanolal (Inderal) and other adrenergic blockers• relieve the adrenergic effects of excess thyroid

hormone (sweating, palpitations, tremors)

• Radioactive iodine – limits the secretion of the

hormone by damaging or destroying thyroid tissue

• Surgical intervention (performed only when pt. is in a

euthyroid state) subtotal thyroidectomy (large goiter) total thyroidectomy (if carcinoma is present)

Nsg. Interventions: Provide calm, restful envt.

1. physical comfort, cool envt. temp., bathe frequently w/ cool water

2. provide adequate rest, avoid muscle fatigue3. stressors in the envt.— noise and lights4. relaxation techniques

Provide adequate nutrients1. calorie, protein, balanced diet (4,000-5,000

cal/day)2. fluid intake3. Restrict stimulants (tea, coffee, alcohol)4. small, frequent feedings if hypermotility is

present5. Daily wt.

Nsg. Interventions:

Provide emotional support

Provide eye care1. eye drops, dark glasses, patch eyes if

necessary2. elevate head of bed for sleep3. restrict dietary sodium4. assess adequacy of lid closure

Be alert for complications

Post-op care after Thyroidectomy

O2 therapy, suction secretions Monitor for signs of bleeding and excessive edema elevate head of bed 30o, support head and neck –

to avoid tension on suturescheck dressing frequently, check behind the neck

for bleeding assess for signs of resp. distress, hoarseness (laryngeal edema or damage) keep tracheostomy set in patient’s room for

emergency use

Post-op Complications: be alert for the possibility of:

1. Tetany (due to hypocalcemia caused by accidental removal of parathyroid glands)

assess for numbness, tingling or muscle twitching

Chvostek’s sign and Trousseau’s sign Ca+ gluconate IV

2. HemorrhageWOF: hypotension, tachycardia, other signs of

hypovolemiaWOF: irregular breathing, swelling, choking---

possible hemorrhage and tracheal compressionWOF: early signs of hemorrhage: repeated

clearing of the throat, difficulty swallowing

Post-op Complications: be alert for the possibility of:

3. Thyroid storm - life-threatening- sudden release of thyroid hormone- fever, tachycardia, increasing restlessness

and agitation, delirium

PARATHYROID GLAND DISORDERS

Hypoparathyroidism is characterized by decrease in

the PTH level

DIABETES MELLITUS(TYPE I, TYPE II)

TWO TYPES OF DIABETES

Diabetes Mellitus

is a chronic disorder of carbohydrate, protein, and fat metabolism resulting from insulin deficiency or abnormality in the use of insulinPredisposing factors:

exact cause of diabetes mellitus remain unknown

genetic / hereditary predisposition viruses pancreatitis pancreatic tumor autoimmune disorder obesity (overweight people require more insulin

to metabolize the food they eat or the number of insulin receptor sites in cells is decreased)

Types1.Insulin – Dependent Diabetes Mellitus (IDDM) or

Type I destruction of beta cells of the pancreas little or no

insulin production requires daily insulin admin. may occur at any age, usually appears below age 15

2.Non Insulin–Dependent Diabetes Mellitus (NIDDM) or Type II probably caused by:

disturbance in insulin reception in the cells number of insulin receptors loss of beta cell responsiveness to glucose leading

to slow or insulin release by the pancreas

occurs over age 40 but can occur in children common in overweight or obese w/ some circulating insulin present, often do not

require insulin

DIAGNOSTIC TEST FOR DM

1. Fasting Blood Sugar (FBS) NPO for 12 hours Normal value= 80-120 mg/dl 140 mg/dl or more – diagnostic of DM

2. Postprandial blood sugar Blood is withdrawn 2 hrs. after a meal N value = < 120mg/dl 200 mg/dl or more is diagnostic of DM

3. Oral Glucose Tolerance Test (OGTT) NPO 12 hrs, no smoking, coffee or tea,

minimize activity, minimize stress obtain FBS, administer 100 gm. Glucose by

mouth diluted in juice; obtain blood and urine specimen after 1, 2 and 3 hrs.

N value = blood glucose rise to 140 mg/dl in the 1st hour and returns to normal by 2nd and 3rd hrs.

Abnormal = blood glucose does not return to normal by 2nd and 3rd hrs.; all urine specimen positive for glucose

Diagnostic Tests for DM

4. Glycosylated hemoglobin Provides information about blood glucose

level during the previous 3 months bec. glucose in the bloodstream attaches to

some of the hemoglobin and stay attached during the 120-day lifespan of the RBC

D-I-A-B-E-T-E-SD- DIET: 50-60% CHO, 20-30% FATS,

Management of Hypoglycemia

1. Give simple sugar orally if pt. is conscious and can swallow – orange juice, candy, glucose tablets, lump of sugar

2. Give Glucagon (SQ or IM) if pt. is unconscious or cannot take sugar by mouth

3. As soon as pt. regains consciousness, he should be given carbohydrate by mouth

4. If pt. does not respond to the above measures, he is given 50 ml of 50% glucose I.V. or 1000 ml of 5%-10% glucose in water I.V.

Oral Antidiabetic AgentsClassification &

ExamplesMechanism of Action

Sulfonylureas-Tolbutamide (Orinase)- Chlorpropamide (Diabinese)- Glipizide (Glucatrol)- Glimepiride (Amaryl)- Glibenclamide

stimulate beta cells of the pancreas to secrete insulin improve binding bet. insulin and insulin receptors no. of insulin receptors

Biguanides- Metformin (Glucophage)

body tissues’ sensitivity to insulin glucose uptake inhibit glucose prod. by the liver

Alpha-Glucosidase Inhibitors- Acarbose (Precose)- Miglitol (Glyset)

delay absorption of glucose in the intestine

Thiazolidinediones- Rosiglitazone (Avandia)- Pioglitazone (Actos)

enhance insulin action at the receptor sites

B. Teach pt. on correct administration of insulin and other hypoglycemic agents.

1. insulin in current use may be stored at room temp., all others in ref. or cool area

2. avoid injecting cold insulin lead to tissue reaction3. roll insulin vial to mix, do not shake, remove air

bubbles from syringe4. press (do not rub) the site after injection (rubbing

may alter the rate of absorption of insulin)5. avoid smoking for 30 mins. after injection (cigarette

smoking absorption)6. Rotate sites Failure to rotate sites may lead to Lipodystrophy Lipodystrophy – localized disturbance of fat

metabolism Ex. Lipohypertrophy – thickening of subcutaneous

tissue at injection site, feel lumpy or hard, spongy result to absorption of insulin making it

difficult to control the pt.’s blood glucose

Teach pt. to estabilish and maintain a pattern of regular exercise Benefits of exercise :

promotes use of CHO & enhances action of insulin blood glucose levels need for insulin the no. of functioning receptor sites for insulin

perform exercise after meals to ensure an adequate level of blood glucose

carry a rapid-acting source of glucose during exercise

excessive or unplanned exercise may trigger hypoglycemia

take insulin and food before active exercise
