Answer to Question 1

ANS: A, B, C
GH stimulation, or provocative testing, involves the use of pharmacologics to provoke the release of GH either directly or indirectly. Provocative testing involves the use of neuromodulators such as levodopa or agents such as clonidine, arginine, insulin, propranolol, or glucagon followed by the measurement GH blood levels. Cortisone is given to replace hormone deficiencies that can occur with GH deficiency. Biosynthetic GH is used to treat GH deficiency
