Answer to Question 1

Ans:
A

Feedback:

Nonexercise activity thermogenesis includes the energy expended in maintaining posture and in activities such as fidgeting. People with increased NEAT may have less fat gain than those with decreased NEAT. Sympathetic stimulation causes brown fat to generate more heat. Research shows that obese patients with excess caloric intake have increased sympathetic activity. Proteins, not carbohydrates, increase metabolic rate more significantly.

Answer to Question 2

Ans:
A, B

Feedback:

Diagnostic procedures for short stature include tests to exclude nonendocrine causes. If the cause is hormonal, extensive hormonal testing procedures are initiated. Tests can be performed using insulin, CHRH, levodopa, and arginine, all of which stimulate GH secretion so that GH reserve can be evaluated. Persantine, dobutamine, and sestamibi are used in cardiac stress testing. Sestamibi is also used in the testing of the parathyroid.
