b. Delivers oxygen to peripheral tissues
c. Stimulate the heart and increase heart rate and force of contraction
d. Promotion of growth and development - ANSWER✔✔-B
Which of the following is the correct order steps for thyroid hormone regulation?
a. The TRH is released from the hypothalamus and stimulates the release of T3 and T4 from the
anterior pituitary, which stimulates TSH from the thyroid to produce biologic effects
b. TSH is released from the hypothalamus and stimulates the release of TRH from the anterior
pituitary which stimulates T3 and T4 from the thyroid to produce biologic effects
c. TRH is released from the hypothalamus and stimulates the release of TSH from the anterior
pituitary, which stimulates T3 and T4 from the thyroid to produce biologic effects

,d. T3 and T4 are released from the hypothalamus to stimulate the release of TRH from the anterior
pituitary, which stimulates TSH from the thyroid to produce biologic effects - ANSWER✔✔-C
(TRH from hypothalamus. TSH from anterior pituitary. T3 & T4 from thyroid inhibit TSH from
anterior pituitary)

b. Low TSH levels
c. Normal TSH levels
d. High TRH levels - ANSWER✔✔-B (Low TSH levels=hyperthyroidism, High=hypothyroidism)

(Synthroid) for their hypothyroidism. Which of the following statements made by the client requires

a. "I should only use one brand and use the same one every time when taking this medication
because not every brand has the identical effect."
b. "This medication should only take a week for an effect to take place."
c. "I should recheck my thyroid hormone levels one month after beginning levothyroxine."
d. "I should take this medication 30-60 minutes before breakfast." - ANSWER✔✔-B

, c. "Once your pregnancy is confirmed, increase your dosage of the medication by 50% percent."
d. "Because fetuses are unable to produce thyroid hormones during the first trimester, make sure to
increase your dosage by 30% as soon as your pregnancy is confirmed to reduce the risk of decreased
IQ and neuropsychological function in the fetus." - ANSWER✔✔-D
One month after your patient started taking levothyroxine for their hypothyroidism, a TSH test is
ordered to test the function of the medication. Which of the following results would indicate that
the thyroid hormone replacement is working?
a. The TSH level is dropping or in normal range.
b. The TSH level is elevating.
c. The TSH level has remained the same.
d. The TRH level is elevating. - ANSWER✔✔-A
Your patient's hypothyroidism is being treated with levothyroxine. What laboratory value would
indicate that your patient needs a decreased dose?
a. A TSH which is below the normal range.
b. A TSH which is above the normal range.
c. A T3 which is below the normal range.
d. A T4 which is below the normal range. - ANSWER✔✔-A (TSH that is below the normal range
indicates a decreased dose because the medication is lowering the TSH by too much.)
