Sample Question
A 23-year old male patient comes to your office who is 3 feet 6 inches tall. your initial diagnosis is that an endocrine disorder accounts for his short stature. To confirm your diagnosis you run a series of laboratory tests. The laboratory results come back with the following findings: 1) plasmaIGF-1levels are extremely low, 2) plasma GH levels are very high, and 3) exogenous GHRH elicits a further increase in GH. What would be the most likely defect in this individual to explain his dwarfism?

Excessive production of somatostat in by periventricular hypothalamic neurons.

Inadequate production of GHRH by arcuate neurons of the hypothalamus

Inadequate production of IGF-1 by somatotrophs of the anterior pituitary gland.

Overproduction of GHRH by arcuate neurons of the hypothalamus.

Inability of the liver to produce IGF-1.
