Answer to Question 1

Correct Answer: 4
Rationale 1: Negative feedback does not stimulate secretion from the first hormone.
Rationale 2: Negative feedback does not stimulate secretion from the second hormone.
Rationale 3: Negative feedback does not prevent a response from the endocrine system.
Rationale 4: Negative feedback loop inhibits secretion of the first hormone.

Answer to Question 2

Correct Answer: 1
Rationale 1: Hypernatremia and hyperglycemia are seen due to the aldosterone effects (mineralcorticoid activity) causing sodium and fluid retention, and elevations of blood glucose due to promotion of gluconeogenesis.
Rationale 2: Hypernatremia would be seen, but hypokalemia would be seen, not hyperkalemia.
Rationale 3: Hypercalcemia and hypokalemia would be seen with this therapy.
Rationale 4: Hypoglycemia and hyponatremia would not be seen with hydrocortisone therapy.
