A) The concentration of a substance in plasma
B) Details about the size of the organ and its location
C) The functioning of endocrine glands
D) The client's blood sugar level
C
Feedback:
Measuring blood hormone levels helps determine the functioning of endocrine glands. A radioimmunoassay determines the concentration of a substance in plasma. The measurement of blood hormone levels will not reveal a client's blood sugar level. Radiographs of the chest or abdomen determine the size of the organ and its location.
