Q

Thyroid can NOT make thyroid hormone without _______________

A

Iodine

26
Q

Primary vs secondary thyroid disease?

A

Primary - this occurs when the thyroid doesn’t produce thyroid hormones Secondary—This occurs when the pituitary gland fails

27
Q

exophthalmos

(hyperthyroidism) or (hyperthyroidism)

A

Hyper

28
Q

TX for HYPOthyroidism

A
  • thyroid hormone replacement (ie, synthroid Cytomel)
  • Avoid sedatives & narcotics —b/c these patients are very sensitive to them and they increase the chances of myedema coma
29

30
Q

Management of Thyroid Storm

33
Q

TRUE OR FALSE

a patient on synthroid should use Fiber laxatives to assist

with the constipation

FALSE

Fiber laxatives reduce absorption of the synthroid and should be avoided3
