Pituitary/Thyroid Disorders Flashcards
1
Q
What is overproduction of GH caused by.
A
A benign pituitary tumor (adenoidal)
-overgrowth of bones and soft tissues
2
Q
Acromegaly
A
Excessive secretion of GH
- thickening of bones and soft tissues
- high IGF; CT and MRI
- enlarged pituitary, headache, facial changes
3
Q
Acromegaly care
A
- hypophysectomy
- radiation
4
Q
Hypopituitarism
A
- visual changes, headaches, anosmia, seizure
- can lead to organ failure
5
Q
Syndrome of inappropriate anti diuretic hormone
A
- older adults
- hyponatremia: muscle cramps
- initial: thirst, dyspnea on exertion
- low urinary output and weight gain (no edema)
- severe: N/V, cramps, cerebral edema
- D: serum osmolality and urine output
6
Q
SIAH Treatment
A
- mild: restrict fluid
- diuretic
- severe: IV NaCl
7
Q
Diabetes insipidus
A
Low ADH
- central: neuro
- nephro
- psycho: thirst
8
Q
Diabetes Insipidus Manifestations
A
- large urine output
- decrease urine gravity and osmolality
- hypernatremia
- polydipsia
- weakness
9
Q
DI Treatment
A
- acute: hypotonic saline or dextrose
- central: demopressin, hormone replacement
- nephrogenic: low sodium diet and thiazide diuretics
- chronic: vasopressin
10
Q
Goiter
A
Enlargement of thyroid gland
11
Q
Thyroid cancer care
A
- M: painless, palpable nodules
- Thyroidectomy: lifelong replacement of thyroid hormones
12
Q
Thyroiditis
A
Due to bacterial, fungal, or viral infection
-chronic autoimmune form can lead to hypothyroidism
13
Q
Hyperthyroidism
A
- women who are 20-40
- most common: Grave’s (hyperthyroidism and thyrotoxicosis)
- increase in metabolism and tissue sensitivity
- abnormal eye appearance with protrusion
- intolerance to heat
14
Q
Graves
A
- autoimmune
- risks: low iodine supply, infection, stress
- antibodies developed to TSH receptor
15
Q
Thyrotoxic crisis
A
- hyperthyroidism complication
- tachycardia, hyperthermia, seizures, vomiting
- T: decrease thyroid hormone and treat manifestations
