• Aldosterone

• Cortisol

• Androgens

• Mineralocorticoid

The adrenal cortex manufactures three classes of adrenal steroids. Which of the three regulates physiologic levels of sodium and potassium and is relatively independent of pituitary gland feedback?

• Aldosterone

• Cortisol

• Androgens

• Mineralocorticoid

• Glucocorticoid

The adrenal cortex manufactures three classes of adrenal steroids. Which of the following is the primary glucocorticoid responsible regulation of carbs, fat, and protein metabolism, maintenance of vascular reactivity, inhibition of inflammation, maintenance of homeostasis during stress, and insulin antagonist?

• Aldosterone

• Cortisol

• Androgens

• Mineralocorticoid

What gland secretes hormones that specifically regulates temperature, weight, energy, and metabolism?

(a)  

The following hormones are secreted by the thyroid gland EXCEPT

• thyroxine (T4)

• calcitonin 

• triiodothyronine (T3) 

• Cortisol

Answer explanation

Cortisol is produced by the adrenal cortex (perimeter of adrenal gland)

What triggers the pituitary to produce more thyroid hormones?

• Low amounts of thyroid hormones

• High amounts of thyroid hormones

• Hyperthyroidism

• Hypothyroidism

Which of the following is a life-threatening condition which occurs most frequently in patients with severe thyrotoxicosis (like Graves Disease) often precipitated by severe illness, infection, or major surgery?

• thyroid storm

• Thyrotoxic crisis

• Hypothyroidism

• Hyperthyroidism

Answer explanation

Symptoms include elevated temp, agitation, and tachycardia

(a)   is a classic feature of graves disease. 

What are the classic signs of hypothyroidism?
