1. Common endocrine problems: Hirsutism
Alopecia
Gynecomastia
Increased neck mass
Polydipsia
Polyphagia
Polyuria
Unexplaned weight gain/loss
2. Organize endocrine disorders: Glandular Disorders
Thyroid
parathyroid
pituatary
adrenal
Diabetes
DM1
DM@
hypoglycemia
Metabolic disorders
Obesity
Gout
3. Pituatary gland: the endocrine system's most influential gland. Under the influence of the hypothalamus, it
regulates growth and controls other endocrine glands.
When thyroid hormone levels in the blood are low, the pituitary releases more TSH. When thyroid hormone levels are
high, the pituitary decreases TSH production.
When theres a problem in the pituatary you will see tsh and T4 both down.
4. How to differentiate hypothyroid and hyperthyroidism.: What differentiates one from
the other
•Causes
, MVU Nurs 623 Exam 2
Study online at https://quizlet.com/_i14bfe
•Clinical presentation
•Diagnostic tests
•Treatment
5. Hyperthyroidism: •Excess secretion & synthesis of one or both: Thyroxine (t4)
triiodothroinine (t3)
Long term effects without treatment:
Heart disease
osteoporosis
Mental disease
infertility
6. Hyperthyroidism clinical findings: "Hot/buldging/fast"
-intolerance to heat
-thin fine hair
-bulging eyes (exopthalmus)
-thryomegaly
-tachycardia
-HTN
-weight loss
-Tremors.
-pretibial myxedema (thickening of skin on shins usually)
-decreased visual acuity
-photophobia.
7. Hypothyroid clinical manifestations: "cold/slow/tired"
-Intolerance to cold, coarse hair/ hair loss, extreme -fatigue, lethargy, slow speech, constipation, brittle -hair/ nails.
-High TSH
-Low free T4 levels
-Once confirmed diagnosis of hypothyroidism, -thyroid peroxidase antibody (TPO) to confirm
-Hashimoto's thyroiditis (gold standard for diagnosis of Hashimoto's)
8. hyperthyroidism causes: Graves disease (diffuse toxic goiter) is most common. Subacute or painless
thyroiditis. Toxic nodular goiter. Factitious hyperthyroidism.

9. Hypothyroidism causes: Hashimoto thyroiditis (90% of cases)
Subacute painless lymphocytic thyroiditis
Hypopituitarism, iodine deficiency, enzyme deficiency
Drugs: Amiodarone, lithium, sulfonamides, phenylbutazone
Hypothalamic dysfunction/hypopituitarism
10. Diagnostic tests for thyroid problems: TSH
Free T 4
- meds can alter labs: Steroids, adrogens, estrogens, salicylates, heparine, iodine containing coumpounds.
If Ft4 normal, then do FT3
Also do CBC and LFT
11. Further testing after initial thyroid testing: TSH receptor antibody
Nuc med scan
24 hour iodine uptake
ultrasound
fine needle biopsy
12. Hyperthyroid (graves disease) Labs
TSH level would be __
T3/T4 would be ___: TSH would be low
Serum free T3 and T4 would be elevated.
Remember the knocking on the door analogy:
the pituitary gland recognizes that the t3 and t4 are elevated, so it will not send anyone to knock on the thyroids door
to increase it (aka will not send out any more TSH)
13. Hypothyroidism (hashimotos's) labs
TSH level would be __
T3/T4 would be ___: TSH level is high
