b. Delivers oxygen to peripheral tissues
c. Stimulate the heart and increase heart rate and force of contraction
d. Promotion of growth and development
CORRECT ANSWER
B
Question 2
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
CORRECT ANSWER
1
@THE STUDY VAULT
, C (TRH from hypothalamus. TSH from anterior pituitary. T3 & T4 from thyroid inhibit TSH
from anterior pituitary)

a. Serum T3
b. Serum T4
c. TSH
d. Creatinine
CORRECT ANSWER
C
Question 4
A TSH test is ordered on your patient to screen for hyperthyroidism. Which of the
following results would you anticipate if the patient did have this condition?
a. High TSH levels
b. Low TSH levels
c. Normal TSH levels
d. High TRH levels
CORRECT ANSWER
B (Low TSH levels=hyperthyroidism, High=hypothyroidism)
Question 5
2
@THE STUDY VAULT
,What is the drug of choice to treat hypothyroidism?
a. Methimazole
b. Levothyroxine
c. Liothyronine
d. Propylthiouracil
CORRECT ANSWER
B
Question 6
You are implementing patient education for a client who has just started taking
levothyroxine (Synthroid) for their hypothyroidism. Which of the following statements
made by the client requires further instruction?
a. "I should only use one brand and use the same one every time when taking this

c. "I should recheck my thyroid hormone levels one month after beginning levothyroxine."
d. "I should take this medication 30-60 minutes before breakfast."

Your patient is a 27-year-old female patient with hypothyroidism taking levothyroxine that
is newly married. Which of the following statements would you say to your patient
regarding pregnancy and her medication?
3
@THE STUDY VAULT
, a. "You should be careful about getting pregnant because levothyroxine is toxic to a fetus."
b. "You should decrease your dosage by 50% once your pregnancy is confirmed."
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."
CORRECT ANSWER
D
Question 8
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.
CORRECT ANSWER
A
Question 9
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.
