Explanation
Glucose tolerance test in combination with a Growth hormone measurement. Acromegaly is a condition in which there is an excess of growth hormone (GH) production by the anterior pituitary gland, resulting in abnormal growth of bones and tissues in the body. The definitive diagnostic test for acromegaly involves a glucose tolerance test combined with a measurement of GH levels. During the test, the client will be given a dose of glucose, and the GH levels will be measured before and after the glucose is given. In acromegaly, the GH levels remain elevated even after glucose administration.
Choice A, bone radiographs, may show the enlarged bones associated with acromegaly, but it is not the definitive diagnostic test for the condition.
Choice C, growth hormone levels, is not specific enough for diagnosing acromegaly, as elevated GH levels can occur in other conditions as well.
Choice D, a serum glucose level, is not specific for acromegaly, as the glucose level may be normal in clients with the condition.
Correct Answer is A
Explanation
Through the application of extreme cold, the tissue is destroyed. Cryosurgery is a procedure that uses extreme cold to destroy abnormal tissues, including tumors and growths. Extreme cold is applied directly to the affected area, and this damages the cells and causes them to die. The destroyed tissue is then gradually absorbed by the body's natural healing processes. Therefore, the correct response to the client's question is that cryosurgery destroys the tissue through the application of extreme cold.
B is not the correct answer because laser surgery uses heat to destroy the tissue, not extreme cold.
C is not the correct answer because cryosurgery does not necessarily remove the entire growth.
D is not the correct answer because cryosurgery freezes the growth and destroys it, not freezes it for removal at a later time.
