Endocrine Flashcards
What is hypopituitarism?
p. 861-866
Deficient secretion of pituitary hormones which lead to retarded growth, gonadotropin deficiencies, thyroid and adrenal deficiencies depending on which hormones are deficient.
What is congenital hypothyroidism?
p. 869-870
Decrease in T3 and T4 which slows the metabolic rate. Usually an
embryonic autosomal recessive defect in the thyroid gland.
What is congenital adrenal hyperplasia?
p. 873-874
Family of genetic conditions affecting the adrenal glands that interferes with normal growth and development including normal development of the genitals due to decreased or absent cortisol synthesis
What is Turner syndrome?
p. 892
Chromosomal disorders interfering with normal growth processes; absence of X chromosomes: 45 XO karyotype
What is Klinefelter Syndrome?
p. 893
Chromosomal disorders interfering with normal growth processes;
excess of X chromosomes: 47 XXY karyotype
S/s of hypopituitarism
- Short stature
- Delayed bone age
- Infertility
- Intolerance to cold
- Fatigue
- Loss of hair
S/s of congenital hypothyroidism
- Pallor
- Decreased temperature
- Hypoactivity (sluggish)
- Decreased muscle tone
- and reflexes
- Large tongue
- Bradycardia
- Constipation
- Feeding difficulties
- Dry and cracked skin
- Edema at eyelids
S/s of congentital adrenal hyperplasia
- Salt wasting - which can be life threatening (shock)
- Hyponatremia
- Hyperkalemia
- Hypoglycemia
- Ambiguous genitalia
S/s of Turner Syndrome
- Edema to hands and feet
- Low posterior hairline/webbed neck
- Low set ears
- Short stature
- Delayed pubertal development
- Amenorrhea
- Normal growth until 3 years, then
- no growth spurts
- Infertile
- Kidney, thyroid, heart and other
- problems
- Learning difficulties
S/s of Klinefelter Syndrome
- Not detected until puberty
- Varying degrees of mental
- impairment
- Severity of intellectual disability
- increases with the additional #
- of X chromosomes
- Tall
- Hypogenitalism
- Gynecomastia
- Sterile
- Poor social interactions
Tx of hypopituitarism
- Replacement of Growth hormone every day until growth plates close (side effects: increase in blood glucose and gynecomastia)
Tx of congenital hypothyroidism
Thyroid hormone replacement
Tx of congenital adrenal hyperplasia
Steroid (hydrocortisone +/- fludrocortisone) replacement, Salt replacement
Tx of Turner Syndrome
Growth hormone Estrogen (beginning around 12 -13 years)
Tx of Klinefelter Syndrome
Testosterone replacement beginning at puberty
Nursing Implications of hypopituitarism
- Family teaching and support
- Child will reach normal adult height, but more slowly than others (takes 3-6 months to see changes)
- Wear a medical identification bracelet
Nursing Implications of Congenital Hypothyroidism
- Give med on empty stomach
- 30 minutes before food
- Separate from iron and calcium supplements by 4 hours
- Testing is done at newborn screening
Nursing Implications of Congenital Adrenal Hyperplasia
- Increased steroid doses during times of illness, injury and stress.
- Foster bonding between parent and child
- Educate parents about reconstructive surgery options
Nursing Implications of Turner Syndrome
- Educate about learning abilities and fertility
- In vitro fertilization can be effective
Nursing Implications of Klinefelter Syndrome
- Therapies (OT, PT, speech)
Causes of hypoglycemia
- Insulin dose too high for food eaten
- Insulin injection into muscle
- Too much exercise for insulin dose
- Too long between snacks/meals
- Too few carbohydrates eaten
- illness, stress
Clinical manifestations of hypoglycemia
- Rapid onset
- irritability, nervousness, tremors, shaky feeling, difficulty concentration or behavior change, confusion, repeating something over and over
- unconsciousness, seizure, shallow breathing, tachycardia
- pallor, sweating
- moist mucous membranes, hunger,
- headache, dizziness, blurred vision, double vision, photophobia
- Numb lips or mouth
Clinical therapy of hypoglycemia
- If conscious, give 15g of carbohydrate
- Wait 15 minutes and recheck blood glucose
- Give another 15g of carbohydrates if 70mg/dL or below
- Recheck the blood glucose in 15 mins
If unconscious, give glucagon by injection
