◉ The nurse is teaching a client who has been newly diagnosed with
hypothyroidism about the function of the thyroid. Which of these
does the nurse explain to the client is the role of the thyroid gland?
Answer: The thyroid gland is responsible for increasing the
metabolic rate.
◉ A patient experiences an increase in thyroid hormone as a result
of a thyroid tumor. Which of the following hormonal responses
demonstrates the negative feedback mechanism? Answer:
Decreased thyroid-stimulating hormone (TSH)
◉ While reviewing the concept of nuclear receptors with a group of
pathophysiology students, the instructor uses the example of type 2
diabetes mellitus patients taking Pioglitazone (Actos), a
thiazolidinedione medication. Because of the peroxisome
proliferator-activated receptors (PPARs), the drug has which effect
on the patients diabetes? Select the best answer. Answer: Promote
glucose uptake and increase the synthesis of certain proteins
involved in fat metabolism, which reduces levels of certain types of
lipids.

adrenal and gonadal steroid hormones excreted? Answer: Bile and
urine
, ◉ The kidney produces 1,25-dihydroxyvitamin D. This form of
vitamin D is responsible for which action in the body? Answer:
Stimulates calcium absorption from the intestine
