A nurse is educating a young boy about the assessments required to make a diagnosis of growth hormone deficiency. What information should the nurse include in the teaching?

Rationale: A. A testicular biopsy is unrelated to growth hormone deficiency and is not part of the diagnostic process. B. An X-ray of the wrists is used to determine bone age, which helps evaluate delayed growth and is a key assessment in diagnosing growth hormone deficiency. C. An MRI may be performed later to assess the pituitary gland, but it is not the primary or initial diagnostic tool. D. A pituitary uptake study using IV dye is not a common or standard procedure in diagnosing growth hormone deficiency in children.
