b) Increase in weight

i) Rationale: If the dose of this medication has been adequate, the nurse should see a decrease in

weight, as hypothyroidism causes a decrease in metabolism with weight gain.

c) Increase in hr of sleep per night

i) Rationale: If the dose of this medication has been adequate, the nurse should see a decrease in

i) Rationale: In hypothyroidism, the nonfunctioning thyroid gland is unable to

respond to the TSH, and no endogenous thyroid hormones are released. This results

in an elevation of the TSH level as the anterior pituitary continues to release the

TSH to stimulate the thyroid gland.

Administration of exogenous thyroid hormones, such as levothyroxine, turns off this

feedback loop, which results in a decreased level of TSH.

3) A nurse is reviewing the medication list for a client who has a new diagnosis of type 2 diabetes mellitus.
