The nursing instructor is talking with the junior nursing class about glial cell tumors
The instructor tells the students that the most common type of glioma is an astrocytoma and that astrocytomas are graded from I to IV, indicating the degree of malignancy. What would the instructor tell the students the grade is based on?
A) Cellular density, number of cells, and appearance
B) Size of cells, number of cells, and appearance
C) Cellular density, cell mitosis, and appearance
D) Cell mitosis, size of cells, and appearance
Ans: C
Feedback: Astrocytomas are the most common type of glioma and are graded from I to IV, indicating the degree of malignancy. The grade is based on cellular density, cell mitosis, and appearance. Usually, these tumors spread by infiltrating into the surrounding neural connective tissue and therefore cannot be totally removed without causing considerable damage to vital structures. The grading of the tumor is not based on the size of the cells or the number of cells.
