Problem: The nurse is caring for a client with acromegaly. The client asks the nurse to explain the difference between acromegaly and gigantism. The nurse differentiates between the two with what statement? "Acromegaly and gigantism are actually terms that are used interchangeably to refer to the same condition of excessive growth hormone secretion." "Both are characterized by excessive growth hormone production; acromegaly occurs after puberty and gigantism before puberty." "Acromegaly affects primarily children and young adults, and gigantism affects the aging population." "Acromegaly is an endocrine disorder of the pituitary gland, and gigantism is a disorder of the musculoskeletal system."
